The Lockheed F-104 Starfighter is a single-engine, supersonic interceptor aircraft which later became widely used as an attack aircraft. Initially a day fighter, it was developed into an all-weather fighter in the late 1960s. It was originally developed by Lockheed for the United States Air Force (USAF), but was later produced by several other nations, seeing widespread service outside the United States. One of the Century Series of fighter aircraft, it was operated by the air forces of more than a dozen nations from 1958 to 2004. Its design team was led by Kelly Johnson, who contributed to the development of the Lockheed P-38 Lightning, Lockheed U-2, Lockheed SR-71 Blackbird, and other Lockheed aircraft.
The F-104 set numerous world records, including both airspeed and altitude records. Its success was marred by the Lockheed bribery scandals, in which Lockheed had given bribes to a considerable number of political and military figures in various nations to influence their judgment and secure several purchase contracts; this caused considerable political controversy in Europe and Japan.
The poor safety record of the Starfighter also brought the aircraft into the public eye, especially in German Air Force (Luftwaffe) service. Fighter ace Erich Hartmann was put into early retirement from the Luftwaffe due to his outspoken opposition to the selection of the F-104.
The final production version of the fighter model was the F-104S, an all-weather interceptor designed by Aeritalia for the Italian Air Force, and equipped with radar-guided AIM-7 Sparrow missiles. An advanced F-104 with a high-mounted wing, known as the CL-1200 Lancer, was considered, but did not proceed past the mock-up stage.
Background and early development
Clarence L. "Kelly" Johnson, the chief engineer at Lockheed's Skunk Works, visited 15 USAF bases in Korea in November 1951 and spoke with fighter pilots about what sort of aircraft they wanted. At the time, the U.S. pilots were confronting the MiG-15 with North American F-86 Sabres, and many felt that the MiGs were superior to the larger and more complex American design. The pilots requested a small and simple aircraft with excellent performance, especially high speed and altitude capabilities. Armed with this information, Johnson immediately started the design of such an aircraft on his return to the United States. In March 1952, his team was assembled; they studied several aircraft designs, ranging from small designs at 8,000 lb (3,600 kg), to fairly large ones at 50,000 lb (23,000 kg). In order to achieve the desired performance, Lockheed chose a minimalist approach: a design that would achieve high performance by wrapping the lightest, most aerodynamically efficient airframe possible around a single powerful engine. The engine chosen was the new General Electric J79 turbojet, an engine of dramatically improved performance in comparison with contemporary designs. The small L-246 design powered by a single J79 remained essentially identical to the Model 083 Starfighter as eventually delivered.
Johnson presented the design to the Air Force on 5 November 1952, and they were interested enough to create a general operating requirement for a lightweight fighter to supplement and ultimately replace the yet-to-fly North American F-100. Three additional companies were named finalists for the requirement: Republic Aviation with the AP-55, an improved version of its prototype XF-91 Thunderceptor; North American Aviation with the NA-212, which eventually evolved into the F-107; and Northrop Corporation with the N-102 Fang, another J79-powered design. Although all three finalists' proposals were strong, Lockheed had what proved to be an insurmountable head start, and was granted a development contract in March 1953 for two prototypes; these were given the designation "XF-104".
Work progressed quickly, with a mock-up ready for inspection at the end of April, and work starting on two prototypes late in May. Meanwhile, the J79 engine was not ready; both prototypes were instead designed to use the Wright J65 engine, a licensed-built version of the Armstrong Siddeley Sapphire. The first prototype was completed by early 1954 and first flew on 5 March at Edwards AFB. The total time from contract to first flight was less than a year.
When the USAF revealed the existence of the XF-104, they only gave a vague description of it, similar to its treatment of the secret F-117A Nighthawk program in the 1980s. No photos of the airplane were released to the public until 1956, even though the XF-104 first flew in 1954. At the April 1956 public unveiling of the YF-104A, the engine inlets were obscured with metal covers and visible weapons, including the M61 Vulcan cannon, were also hidden. Despite the secrecy, a drawing of the F-104 appeared in the August 1954 edition of Popular Mechanics that was very close to the actual design.
The prototype made a planned hop into the air during taxi trials on 28 February 1954 and flew about five feet (1.5 m) off the ground for a short distance, but was not counted as a first flight. On the first official flight on 5 March 1954, it experienced landing gear retraction problems. The second prototype was destroyed a few weeks later during gun-firing trials, but in November 1955 the XF-104 was accepted by the USAF.
Based on the XF-104 testing and evaluations, the next variant, the YF-104A, was lengthened and fitted with a General Electric J79 engine, modified landing gear, and modified air intakes. The YF-104A and subsequent models were 5 feet 6 inches (1.68 m) longer than the XF-104 to accommodate the larger GE J79 engine. The YF-104 initially flew with the GE XJ79-GE-3 turbojet with 9,300 pounds of dry thrust (14,800 with afterburner), which was later replaced by the J79-GE-3A with an improved afterburner.
The first YF-104A flew on 17 February 1956 and, with the other 16 trial aircraft, were soon carrying out aircraft and equipment evaluation and tests. Lockheed made several improvements to the aircraft throughout the YF-10A testing period, including strengthening the airframe, adding a ventral fin to improve directional stability at supersonic speed, and installing a boundary layer control system (BLCS) to reduce landing speed.
Problems were encountered with the J79 afterburner; further delays were caused by the need to add AIM-9 Sidewinder air-to-air missiles. On 28 January 1958, the first production F-104A to enter service was delivered to the 83rd Fighter Interceptor Wing.
A total of 2,578 F-104s were produced by Lockheed and under license by various foreign manufacturers.
The Starfighter's airframe was all-metal, primarily duralumin with some stainless steel and titanium. The fuselage was approximately two and a half times longer than the airplane's wingspan. The wings themselves were centered on the horizontal reference plane, and were located substantially farther back on the fuselage than most contemporary designs. The aft fuselage was somewhat elevated from the horizontal reference plane, and the nose was "drooped"; this caused the aircraft to assume a slight "nose-up" attitude, which allowed the plane to fly at the minimum-drag angle of attack. As a result, the pitot tube, air inlet scoops, and engine thrust line were all canted slightly with respect to the longitudinal centerline of the fuselage.
The F-104 featured a radical wing design. Most jet fighters of the period used a swept-wing or delta-wing, which provided a reasonable balance between aerodynamic performance, lift, and internal space for fuel and equipment. The Lockheed tests, however, determined that the most efficient shape for high-speed supersonic flight was a very small, straight, mid-mounted, trapezoidal wing. Much of the data on the wing shape was derived from testing done with the experimental unmanned Lockheed X-7, which used a similar-shaped wing. The wing's leading edge of the wing was swept back at 26 degrees, with the trailing edge swept forward by a slightly smaller amount.
The new wing design was extremely thin, with a thickness-to-chord ratio of only 3.36% and an aspect ratio of 2.45. The wing's leading edges were so thin (.016 in, 0.41 mm) that they presented a cut hazard to ground crews: protective guards had to be installed on the edges during ground operations maintenance. The thinness of the wings required fuel tanks and landing gear to be placed in the fuselage, and the hydraulic cylinders driving the ailerons were limited to 1-inch (25 mm) thickness in order to fit.
The small, highly loaded wing resulted in an unacceptably high landing speed, even after adding both leading- and trailing-edge flaps. As a result, the aircraft designers developed a boundary layer control system, or BLCS, of high-pressure bleed air, which was blown over the trailing-edge flaps to lower landing speeds by more than 30 knots (56 km/h; 35 mph) and help make landing the airplane safer. The system proved to be a maintenance problem in service, however, and landing without the BLCS engaged could be a harrowing experience.[failed verification]
The stabilator (fully moving horizontal stabilizer) was mounted high atop the fin to reduce inertia coupling. Because the vertical fin was only slightly shorter than the length of each wing and nearly as aerodynamically effective, it could act as a wing-on-rudder application, rolling the aircraft in the opposite direction of rudder input. To offset this effect, the wings were canted downward at a 10° negative-dihedral (anhedral) angle. This downward canting also had the effect of improving roll control during high-g maneuvers during air-to-air combat.
The fuselage had a high fineness ratio, i.e. slender, tapered towards the sharp nose, and a small frontal area. The tightly packed fuselage contained the radar, cockpit, cannon, fuel, landing gear, and engine. The fuselage and wing combination provided low drag except at high angle of attack (alpha), at which point induced drag became very high. The F-104 had good acceleration, rate of climb, and potential top speed, but its sustained turn performance was poor. A "clean" (no external weapons or fuel tanks) F-104 could sustain a 7-g turn below 5,000 feet with full afterburner, but given the aircraft's prodigious fuel consumption at that altitude and relatively small fuel capacity, such a maneuver would dramatically reduce its time on station.
The F-104 was designed to use the General Electric J79 turbojet engine, fed by side-mounted intakes with fixed inlet cones optimized for performance at Mach 1.7 (increased to Mach 2 for later F-104s equipped with more powerful J79-GE-19 engines). Unlike some supersonic aircraft, the F-104 did not have variable-geometry inlets; instead at high Mach numbers excess air was bypassed around the engine. This bypass air also helped cool the engine. Its thrust-to-drag ratio was excellent, allowing a maximum speed well in excess of Mach 2. Available thrust was actually limited by the geometry of the inlet scoop and duct; the aircraft was capable even higher Mach numbers except for the aerodynamic heating limitations of the aluminum structure.
The engine consisted of a 17-stage compressor, accessory drive section, annular combustion chamber, three-stage turbine, and afterburner. The most powerful version of the J79, the J79-GE-19, was rated at 52.8 kN (11,900 lbf) dry thrust and 79.6 kN (17,900 lbf) with afterburner. Bleed air from the compressor's 17th stage was used for a number of purposes: the BLCS, cabin pressurization and air conditioning, hot-air jet rain removal, fuel transfer, canopy and windshield defogging and defrosting, pressure for the pilot's anti-G suit, radar waveguide and purging of gas from the M61 autocannon. The accessory drive ran two hydraulic pumps, two variable-frequency generators, the generator for the tachometer, and pumps for engine fuel and oil.
The basic armament of the F-104 was the 20 mm (0.79 in) M61 Vulcan autocannon. As the first aircraft to carry the weapon, testing of the Starfighter revealed issues with the initial version of the M61: the Gatling-mechanism cannon suffered problems with its linked ammunition, being prone to misfeed and presenting a foreign object damage (FOD) hazard with discarded links. A linkless ammunition feed system was developed for the upgraded M61A1 installed in the F-104C; the M61A1 has subsequently been used by a wide variety of American combat aircraft.
The cannon, mounted in the lower part of the port fuselage, was fed by a 725-round drum behind the pilot's seat. With its firing rate of 6,000 rounds per minute, the cannon would empty the drum after just over seven seconds of continuous fire. The cannon was omitted in all the two-seat models and some single-seat versions, including reconnaissance aircraft and the early Italian F-104S, with the gun bay and ammunition tank typically replaced by additional fuel tanks. The gun's location was advantageous as gun-flash was not in the pilot's line of sight, and so would not interfere with night-adjusted vision.
Two AIM-9 Sidewinder air-to-air missiles could be carried on the wingtip stations, which could also be used for fuel tanks. The F-104C and later models added a centerline pylon and two underwing pylons for bombs, rocket pods, or fuel tanks; the centerline pylon could carry a nuclear weapon. A "catamaran" launcher for two additional Sidewinders could be fitted under the forward fuselage, although the installation had minimal ground clearance and rendered the seeker heads of the missiles vulnerable to ground debris. The F-104S models added a pair of fuselage pylons beneath the intakes available for conventional bomb carriage and an additional pylon under each wing, for a total of nine.
Early Starfighters were also capable of carrying and launching a single MB-1 (AIR-2A Genie) rocket-powered nuclear missile using an extending trapeze launcher. This configuration was tested on a single aircraft but was not adopted for service use; however, NASA later used it for launching test rockets.
The initial USAF Starfighters had a basic RCA AN/ASG-14T1 ranging radar, tactical air navigation system (TACAN), and an AN/ARC-34 UHF radio. The AN/ASG-14 fire control system used a 24-inch (610 mm) pencil-beam radar antenna with two independent sights, one optical one infrared. Early versions of the radar had a range of approximately 20 miles (32 km) in search mode, with later models reaching up to 40 miles (64 km); the scan pattern was spiral, covering a 90-degree cone. Search mode was usable only above 3,000 feet (910 m) due to ground return effects below that altitude. Track mode was usable within 10 miles (16 km) of the target, which narrowed the scan to 20 degrees and initiated a strobe sweep between 300 and 3,000 yards (270 and 2,740 m) in auto-acquisition mode. The radar also had a third, receive-only mode useful for locking onto source of interference from electronic countermeasures (ECM).
In the late 1960s, Lockheed developed a more advanced version of the Starfighter, the F-104S, for use by the Italian Air Force. Similar to the F-104G, Lockheed produced two main variants of the F-104S, a, all-weather interceptor (CI) and a strike aircraft (CB). The CI variant received a FIAR/NASARR F15G radar with AIM-7 Sparrow guidance capability; however, the new missile-guidance avionics came at the expense of the M61A1 Vulcan cannon, which was removed to make room. The CB variant was equipped with a FIAR/NASARR R21G-H radar and a radar altimeter for low-level strike missions, retaining the cannon as its only air-to-air weapon.
As part of the Aggiornamento Sistema d'Arma (ASA), or "Weapons System Upgrade" in the mid-1980s, both variants were given an ALQ-70/72 ECM and a FIAR/NASARR R-21G/M1 radar with frequency hopping and look-down/shoot-down capability. The new radar and guidance systems enabled the aircraft to carry both the new AIM-9L Sidewinder infrared-guided missile (replacing the older AIM-9B) as well as the AIM-7 Sparrow and the Selenia Aspide radar-guided missiles.
Early Starfighters used a downward-firing ejection seat (the Stanley C-1), out of concern over the ability of an upward-firing seat to clear the "T-tail" empennage. This presented obvious problems in low-altitude escapes, and 21 USAF pilots, including test pilot Captain Iven Carl Kincheloe Jr., failed to escape from their stricken aircraft in low-level emergencies because of it. The downward-firing seat was replaced by the Lockheed C-2 upward-firing seat, which was capable of clearing the tail, but still had a minimum speed limitation of 90 kn (104 mph; 167 km/h). Many export Starfighters were later retrofitted with Martin-Baker Mk.7 "zero-zero" (zero altitude and zero airspeed) ejection seats.
The Starfighter was designed for production rates of up to 20 airplanes per day from a single assembly line. The entire aircraft was designed for modular assembly and disassembly: the two principal fuselage sections were split along the vertical centerline and completely assembled in two separate halves; all equipment, including wiring and plumbing, were installed inside the two halves before being joined together. The wings were then attached with only ten bolts plus a fairing.
U.S. Air Force
Although the F-104 was designed as an air-superiority fighter, the United States Air Force's immediate need at the time was for a supersonic interceptor. In the late 1950s, the United States government believed it was significantly behind the USSR in terms of the size of its jet-powered bomber fleet. In response, the USAF had ordered two interceptors from Convair, the F-102 Delta Dagger and the F-106 Delta Dart, but both aircraft were experiencing long development delays. The Starfighter's speed and rate-of-climb performance intrigued the Air Force, who pressed the F-104A into service as an interim interceptor with the Air Defense Command (ADC), even though its range and armament were not well-suited for the role. On 26 February 1958, the first unit to become operational with the F-104A was the 83rd Fighter Interceptor Squadron at Hamilton AFB, California.
The newly operational aircraft experienced problems with both the J79 engine and M61 cannon, and after just three months of service, the unit was grounded after a series of engine-related accidents. The aircraft were then fitted with the J79-GE-3B engine and another three ADC units equipped with the F-104A. During this time, the Air Force's interest in the Starfighter was waning due to a shift in strategy toward fighters with longer range and heavier ordnance loads. As a result, the USAF reduced their orders from 722 to 296, and the F-104A and F-104B aircraft of the 83rd, 56th, and 337th Fighter Interceptor Squadrons (FIS) were handed over to the 151st, 157th, and 197th Squadrons of the Air National Guard after less than a year of service with ADC.
Taiwan Strait Crisis of 1958
In August 1958, only a few months after establishing operational readiness with the F-104, the 83rd FIS was assigned to a peacekeeping mission in Taiwan after the People's Republic of China began an intense artillery campaign against the Nationalist Chinese on the disputed islands of Quemoy and Matsu. Tensions between the two forces were already high; artillery duels were ongoing since the first crisis in 1954, and the PLAAF had recently relocated 200 MiG-15s and MiG-17s to airfields on the mainland opposite Taiwan. The Starfighters' presence, according to Col. Howard "Scrappy" Johnson, was so the PLAAF would "track them on their radar screens...and sit back and scratch their head in awe."
On 10 September, the first F-104s arrived in Formosa, delivered disassembled by C-124 Globemaster II transport aircraft. This was the first time that air transport was used to move fighter aircraft long distances. Within 30 hours of arriving, 1Lt Crosley J. Fitton had the first of the 83rd's airplanes in the air, and by 19 September the entire unit was ready for day or night alert status. The F-104 flew a number of supersonic runs between Taiwan and mainland China at speeds up to Mach 2 as an air-superiority demonstration, and though there were no direct enemy engagements prior to withdrawal after the 6 October ceasefire, the Starfighter provided a significant deterrent effect. USAF Gen Laurence Cuter, commander-in-chief of the Pacific Air Forces, reported that the F-104A had "made a tremendous impression on both sides of the Taiwan Strait".
Berlin Crisis of 1961
During the Berlin Crisis of 1961, President John F. Kennedy ordered 148,000 United States National Guard and reserve personnel to active duty on 30 August 1961, in response to Soviet moves to cut off Allied access to Berlin. 21,067 individuals were from the Air National Guard (ANG), forming 18 fighter squadrons, four reconnaissance squadrons, six transport squadrons, and a tactical control group. On 1 November 1961, the USAF mobilized three more ANG fighter interceptor squadrons. In late October and early November, eight of the tactical fighter units flew to Europe with their 216 aircraft in "Operation Stair Step". Because of their short range, 60 F-104As were airlifted to Europe in late November, among them the 151st FIS and 157th FIS. As with the Taiwan crisis three years earlier, the Starfighter did not directly engage any enemy fighters, but its presence provided a powerful air-superiority deterrent; it demonstrated very quick reaction times and exemplary acceleration during practice intercepts, and proved superior to all other available fighters in the theater. The crisis ended in the summer of 1962 and the ANG personnel returned to the United States, but the F-104's solid performance helped convince the ADC to recall some F-104s back into active USAF service the following year.
The subsequent F-104C entered service with USAF Tactical Air Command (TAC) as a multi-role fighter and fighter-bomber. The 479th Tactical Fighter Wing at George AFB, California, was the first unit to equip with the type in September 1958. Although not an optimum platform for the theater, the F-104 did see limited service in the Vietnam War. In 1967, these TAC aircraft were transferred to the Air National Guard.
Starfighter squadrons made two deployments to Vietnam. Commencing with Operation Rolling Thunder, the Starfighter was used both in the air-superiority role and in the air-support mission. On 19 April 1965 the 476th Tactical Fighter Squadron (TFS) of the 479th Tactical Fighter Wing (TFW) arrived at Da Nang AB to help protect the F-105 Thunderchiefs against MiG-17s and especially MiG-21s that were beginning to be flown by the Vietnamese Peoples' Air Force (VPAF). The F-104 was also deployed extensively as a barrier combat air patrol (BARCAP) protector for the EC-121D Warning Star airborne early warning aircraft patrolling off the North Vietnamese coast. The F-104s were successful in deterring MiG interceptors and performed well as close support aircraft, though they were largely uninvolved in aerial combat and recorded no air-to-air kills during the conflict. The North Vietnamese were well aware of the F-104's performance, and the 479th TFW's pilots felt that the MiGs deliberately avoided engaging them. Twenty-five MiG kills were scored by fighters controlled by EC-121 Big Eye missions, and their Starfighter escorts played a vital role in ensuring their safety.
During the first F-104 deployment from April to December 1965, Starfighters flew a total of 2,937 combat sorties. These sorties resulted in the loss of five aircraft, one from the 476th TFS deployed from April to July 1965, and four from the 436th Tactical Fighter Squadron deployed from July to October 1965. Two Starfighters were shot down by ground fire, one was shot down by a Shenyang J-6 when Capt. Philip E. Smith strayed into Chinese airspace, and two were lost to a mid-air collision while searching for Smith's missing jet. No losses were reported from the 435th Tactical Fighter Squadron's first deployment from October to December 1965.
Starfighters returned to Vietnam when the 435th Tactical Fighter Squadron re-deployed from June 1966 until August 1967. During this time F-104s flew a further 2,269 combat sorties, for a total of 5,206. F-104s operating in Vietnam were upgraded in service with AN/APR-25/26 radar warning receiver equipment, with one example on display in the Air Zoo in Kalamazoo, Michigan. During the second deployment, an additional nine aircraft were lost for a total of 14 F-104s lost to all causes in Vietnam. In July 1967, the Starfighter units transitioned to the McDonnell Douglas F-4 Phantom II.

North American service
The U.S. Air Force was less than satisfied with the Starfighter, and procured only 296 examples in single-seat and two-seat versions. At the time, USAF doctrine placed little importance on air superiority (fighter-to-fighter), and the Starfighter was deemed inadequate for either the interceptor (fighter-to-bomber) or tactical fighter-bomber role, lacking both payload capability and endurance in comparison with other USAF aircraft. The F-104's U.S. service was quickly wound down after the aircraft's second deployment to southeast Asia in 1967. Although the remaining F-104As in regular USAF service had been recently fitted with more powerful and more reliable J79-GE-19 engines, the last USAF Starfighters left regular Air Force service in 1969. The aircraft continued in use with the Puerto Rico Air National Guard until 1975 when it was replaced in that organization by the A-7 Corsair II.
The last use of the F-104 Starfighter in U.S. markings was training pilots for the West German Air Force, with a wing of TF-104Gs and F-104Gs based at Luke Air Force Base, Arizona. Although operated in USAF markings, these aircraft (which included German-built aircraft) were owned by West Germany. They continued in use until 1983.
At dawn on 6 September 1965, Flight Lieutenant Aftab Alam Khan of Pakistan claimed an Indian Dassault Mystère IV over West Pakistan and damaged another, marking the start of aerial combat for the F-104 in the Indo-Pakistani War of 1965. The kill with an AIM-9B Sidewinder is claimed by the Pakistani Air Force (PAF) as the first combat kill by any Mach 2 aircraft and the PAF's first missile kill, though the Indian Air Force (IAF) denied the loss. The Starfighter was also instrumental in intercepting an IAF Folland Gnat on 3 September 1965. F-104s were vectored to intercept the Gnat flying over Pakistan, which was returning to its home base. The F-104s, closing in at supersonic speed, caused the Gnat pilot to land at a nearby disused Pakistani airfield and surrender. The IAF disputed the PAF's claim of forced landing and stated that the landing was an error of the pilot, who made an emergency landing thinking it to be an Indian airstrip. The IAF Gnat is now displayed at the PAF Museum, Karachi.
The first direct air-to-air combat engagements between the F-104 and the MiG-21 took place during the Indo-Pakistani War of 1971. MiG-21FLs flown by the IAF shot down at least two, and possibly four, PAF Starfighters without sustaining any losses. The first confirmed loss occurred on 12–13 December 1971, when MiG-21FLs of the IAF's No. 47 Squadron shot down a PAF F-104 of No. 9 Squadron flown by Wing Commander Mervyn Middlecoat over the Gulf of Kutch. The second confirmed PAF F-104 loss occurred several days later on 17 December when Flight Lieutenant Samad Changezi of No. 9 Squadron, flying a Starfighter on loan from Jordan, was shot down by IAF MiG-21FLs of No. 29 Squadron. The IAF also claimed two additional PAF Starfighter kills that same day, one of whom was Changezi's wingman, Squad Leader Rashid Batti; the PAF claimed he was able to return without damage to Masroor.
Post-war sanctions forced an early retirement of F-104s from the PAF due to lack of maintenance support.
1967 Taiwan Strait Conflict
On 13 January 1967, four Republic of China (Taiwan) Air Force F-104G aircraft engaged a formation of J-6/MiG-19s of the People's Liberation Army Air Force over the disputed island of Kinmen (Qemoy). Major Hu Shih-lin and Captain Shih Bei-puo each shot down one MiG-19. This marked the first uncontested F-104 combat victory in the world.[failed verification] One F-104 did not return to base and its pilot was listed as MIA.
F-104 designer Kelly Johnson stated that this particular battle illustrated the relative strengths and weaknesses of the Starfighter in aerial combat. "We had them on acceleration and we had them on steady-state altitude, but we could not turn with them," said Kelly, who at the time was working on the larger-winged, more-maneuverable CL-1200 Lancer derivative of the F-104.
Other international service
At the same time that the F-104 was falling out of U.S. favor, the West German Air Force was looking for a multi-role combat aircraft to operate in support of a missile defense system. In response, Lockheed reworked the Starfighter from a fair-weather fighter into an all-weather ground-attack, reconnaissance, and interceptor aircraft, and presented it as the F-104G. The redesigned aircraft was chosen over the English Electric P.1 (later the Lightning), Grumman F11F-1F Super Tiger, Chance Vought F-8U Crusader, and Republic F-105 Thunderchief. The Starfighter found a new market with other NATO countries as well, and eventually a total of 2,578 of all variants of the F-104 were built in the U.S. and abroad for various nations. Several countries received their aircraft under the U.S. government-funded Military Aid Program (MAP). The American engine was retained but built under license in Europe, Canada, and Japan. The Lockheed ejector seats were retained initially but were replaced later in some countries by the safer Martin-Baker seat.
The so-called "Deal of the Century" produced substantial income for Lockheed, but the resulting bribery scandals caused considerable political controversy in Europe and Japan. In 1976, a U.S. Senate investigating committee led by Senator Frank Church determined that Lockheed had paid US$22 million in bribes to foreign officials during the negotiations process of the sale of its aircraft, including the F-104 Starfighter. In Germany, Minister of Defence Franz Josef Strauss was accused of having received at least US$10 million for West Germany's purchase of the F-104 in 1961. On 26 August 1976, Prince-consort Bernhard of the Netherlands was forced to resign as Inspector-General of the Dutch Armed Forces after being accused of accepting approximately US$1.1 million in bribes.
The international service of the F-104 began to wind down in the late 1970s, being replaced in many cases by the General Dynamics F-16 Fighting Falcon, but it remained in service with some air forces for another two decades. The last operational Starfighters served with the Italian Air Force, which retired them on 31 October 2004.
The Starfighter served with NASA from 1956 until 1994. A total of 12 F-104A, F-104B, F-104N, and TF-104G aircraft performed high-speed and altitude flight research at Dryden Flight Research Center. The F-104 also performed many safety chase missions in support of advanced research aircraft, and provided a launch platform for sounding rockets.
In August 1956, the USAF transferred YF-104A serial number 55-2961 to the National Advisory Committee for Aeronautics (NACA, the predecessor of NASA), designating it NF-104A. In preparation for the X-15 test program of the late 1950s, it was fitted with the reaction control system (RCS) consisting of hydrogen peroxide-powered thrusters mounted in the aircraft's nose and wingtips. This system provided invaluable experience for future X-15 pilots and astronauts in spacecraft control and maneuverability. The trials began in 1959 and concluded in 1961, after which the aircraft was used for other NASA purposes until it was retired in November 1975.
Between August and October 1963, Lockheed delivered three single-seat F-104G Starfighters to NASA, designated F-104N for use as high-speed chase aircraft. These were the only Starfighters built by Lockheed specifically for NASA; all other NASA aircraft were transferred from the USAF. The third of these F-104Ns, number 013, was destroyed on 8 June 1966 in a mid-air collision with a North American XB-70 during a publicity photo flight for General Electric.
One NASA F-104G, registration N826NA, was equipped with a flight test fixture (FTF) consisting of a pylon mounted on the fuselage centerline. The FTF contained instruments to record and transmit the research data in real-time to engineers in mission control at Dryden. One application of the FTF was testing the heat-resistant tiles for use on the Space Shuttle, ensuring their bonding was sufficient at high speeds and evaluating their performance in moisture. The last of these missions flew on 31 January 1994, bringing the F-104's service with NASA Dryden to a close after more than 18,000 flights.
Use as space launch platform
In 2011, 4Frontiers Corporation and Starfighters Inc (a private F-104 operator) began working together on a project to launch suborbital sounding rockets from F-104s flying out of Kennedy Space Center. First launches were expected to occur in 2012. As of 16 July 2017, both the 4Frontiers Corporation and Star Lab suborbital websites were unresponsive, and there appeared to be no mention of 4Frontiers or the joint project on the Starfighters Inc website.
In early 2016, another venture, CubeCab, was working on a rocket system that would launch CubeSats from F-104s. The company said it planned to begin providing launch services "in early 2020".
The Starfighter was the first combat aircraft capable of sustained Mach 2 flight, and its speed and climb performance remain impressive even by modern standards. Equipped with razor-edge thin-blade supersonic wings (visible from the cockpit only in the mirrors), it was designed for optimum performance above Mach 1.4. If used appropriately, with high-speed surprise attacks and good use of its exceptional thrust-to-weight ratio, it could be a formidable opponent. It was exceptionally stable at high speed, i.e., 600+ knots (1,100+ km/h; 690+ mph) at very low level, making it a potent tactical nuclear strike-fighter. However, when lured into a low-speed turning contest with conventional subsonic opponents (as Pakistani pilots were with Indian Hunters in 1965), the outcome of dogfights was always in doubt. The F-104's large turn radius was due to the high speeds required for maneuvering, and its high-alpha stalling and pitch-up behavior was known to command respect. In reference to the F-104's low-speed turn performance, a humorous colloquialism was coined by a Canadian pilot and referred to by F-104 pilots the world over: "Banking with intent to turn."
Takeoff speeds were between 180 and 200 knots (330 and 370 km/h; 210 and 230 mph), with the pilot needing to swiftly raise the landing gear to avoid exceeding the limit speed of 260 knots (480 km/h; 300 mph). Climb and cruise performance were outstanding; occasionally a "slow" light would illuminate on the instrument panel at around Mach 2 to indicate that the engine compressor was nearing its limiting temperature and the pilot needed to throttle back. Landings were also done at high speed: the downwind leg of the circuit was typically flown at approximately 210 knots (390 km/h; 240 mph) with flaps in landing configuration, with the long, flat final approach flown at around 175 knots (324 km/h; 201 mph) and touchdown at 155 to 160 knots (287 to 296 km/h; 178 to 184 mph). Extra fuel, crosswinds or gusts, external stores, and other considerations could add up to 20 knots (37 km/h; 23 mph) to these speeds. Unlike most aircraft, the F-104 was landed with the engine at high power, as the boundary layer control system lost effectiveness below approximately 82 percent engine rpm. Pilots were instructed not to cut the throttle while the plane was still airborne, as doing so would cause an abrupt (and generally uneven) loss of lift. A 16-foot (4.9 m) drag chute combined with effective brakes shortened the Starfighter's landing roll.
The F-104 series all had a very high wing loading (made even higher when carrying external stores). During the early stall tests, the aircraft demonstrated the tendency to suddenly "pitch up" once it reached an angle of attack of approximately 15 degrees. This "pitch up" would result in a rapid increase in angle of attack to approximately 60 degrees, accompanied by lateral and directional oscillation, and followed by sudden uncontrolled yaw and roll. At this point the aircraft would be essentially tumbling, descending at a rate of 12,000–15,000 feet per minute (3,700–4,600 m/min). To combat this, an automatic pitch control (APC) was added, which initiated corrective action at the proper time to prevent reaching an angle of attack high enough to cause pitch-up under any operating condition. The high angle of attack area of flight was protected by a stick shaker system to warn the pilot of an approaching stall, and if this was ignored, a stick pusher system would pitch the aircraft's nose down to a safer angle of attack; this was often overridden by the pilot despite flight manual warnings against this practice.
Another serious design issue that the aircraft encountered was T-tail flutter; Dick Heppe, who served as the initial project aerodynamics engineer for the F-104 program, recalled that "without question, the single most difficult technical challenge encountered in the XF-104 and F-104A development programs was the catastrophic flutter problem of the unique T-tailed empennage configuration." Because the horizontal tail's center of gravity was well aft of both the bending and torsional axes of the vertical tail to which it was attached, it was highly vulnerable to flutter at transonic speeds. During a test flight of the F-104A, the surviving XF-104 was flying chase to observe, and encountered violent T-tail flutter that caused the tail to separate from the aircraft. The test pilot of the XF-104 successfully ejected. This behavior was remedied by increasing the thickness of the stainless steel box covers used in the tail assembly.
The J79 was a brand-new engine, with development continuing throughout the YF-104A test phase and during service with the F-104A. The engine featured variable incidence compressor stator blades, a design feature that altered the angle of the stator blades automatically with altitude and temperature. A condition known as "T-2 reset", a normal function that made large stator blade angle changes, caused several engine failures on takeoff. It was discovered that large and sudden temperature changes (e.g., from being parked in the sun prior to becoming airborne) were falsely causing the engine stator blades to close and choke the compressor. The dangers presented by these engine failures were compounded by the downward ejection seat, which gave the pilot little chance of a safe exit at low level. The engine systems were subsequently modified and the ejection seat changed to the more conventional upward type. Uncontrolled tip-tank oscillations sheared one wing off of an F-104B; this problem was apparent during testing of the XF-104 prototype and was eventually resolved by filling the tank compartments in a specific order.
A further engine problem was that of uncommanded opening of the variable thrust nozzle (usually through loss of engine oil pressure, as the nozzles were actuated using engine oil as hydraulic fluid); although the engine would be running normally at high power, the opening of the nozzle resulted in a drastic loss of thrust. A modification program installed a manual nozzle closure control which reduced the problem. The engine was also known to suffer from afterburner blowout on takeoff, or even non-ignition, resulting in a major loss of thrust that could be detected by the pilot—the recommended action was to abandon the takeoff. The first fatal accident in German service was caused by this phenomenon. Some aircrews experienced uncommanded "stick kicker" activation at low level when flying straight and level, so F-104 crews often flew with the system deactivated. Asymmetric flap deployment was another common cause of accidents, as was a persistent problem with severe nose wheel "shimmy" on landing that usually resulted in the aircraft leaving the runway and in some cases even flipping over onto its back.[page needed]
The introduction of a highly technical aircraft type to a newly reformed air force was fraught with problems. Many pilots and ground crew had settled into civilian jobs after World War II and had not kept pace with developments, with pilots being sent on short "refresher" courses in slow and benign-handling first-generation jet aircraft. Ground crew were similarly employed with minimal training and experience, which was one consequence of a conscripted military with high turnover of service personnel. Operating in poor northwest European weather conditions (vastly unlike the fair weather training conditions at Luke AFB in Arizona) and flying low at high speed over hilly terrain, a great many accidents were attributed to controlled flight into terrain (CFIT). German Air Force and Navy losses totaled 110 pilots, around half of them naval officers.
One contributing factor to this was the operational assignment of the F-104 in German service: it was mainly used as a fighter-bomber, as opposed to the original design of a high-speed, high-altitude fighter/interceptor. In addition to the much lower-level mission profiles, the installation of additional avionic equipment in the F-104G version, such as the inertial navigation system, added far more distraction to the pilot and additional weight that further hampered the flying abilities of the plane. In contemporary German magazine articles highlighting the Starfighter safety problems, the aircraft was portrayed as "overburdened" with technology, which was considered a latent overstrain on the aircrews.
In 1966 Johannes Steinhoff took over command of the Luftwaffe and grounded the entire Luftwaffe and Bundesmarine F-104 fleet until he was satisfied that problems had been resolved or at least reduced. In later years, the German safety record improved, although a new problem of structural failure of the wings emerged. Original fatigue calculations had not taken into account the high number of g-force loading cycles that the German F-104 fleet was experiencing, and many airframes were returned to the depot for wing replacement or outright retirement. Towards the end of Luftwaffe service, some aircraft were modified to carry a flight data recorder or "black box" which could give an indication of the probable cause of an accident. Erich Hartmann, the world's top-scoring fighter ace, commanded one of Germany's first (post-war) jet fighter-equipped squadrons and deemed the F-104 to be an unsafe aircraft with poor handling characteristics for aerial combat. In Navy service it lacked the safety margin of a twin engine design like the Blackburn Buccaneer. To the dismay of his superiors, Hartmann judged the fighter unfit for Luftwaffe use even before its introduction.
Normal operating hazards
The causes of a large number of aircraft losses were the same as for any other similar type. They included: bird strikes (particularly to the engine), lightning strikes, pilot spatial disorientation, and mid-air collisions with other aircraft. A particularly notable accident occurred on 19 June 1962 when a formation of four F-104F aircraft, practicing for the type's introduction-into-service ceremony, crashed together after descending through a cloud bank. Three Germans and one American pilot were killed, and the four aircraft destroyed. This accident was explained as probable spatial disorientation of one of the (trainee) wingmen,[verification needed] and formation aerobatic teams were consequently banned by the Luftwaffe from that day on.
The safety record of the F-104 Starfighter became high-profile news in the mid-1960s, especially in Germany. The Federal German Republic initially ordered 700 (instead of the French Mirage), and later another 216, a total of 916 aircraft. Deliveries started in January 1962 and before the end of the month, the first of no fewer than 262 German F-104s had crashed. In June 1962 four F-104s crashed on the same day. 116 German pilots died during peacetime between 25 January 1962 and 11 December 1984. Grieving widows sued Lockheed from 1969, and by 1975 more than thirty of them had received 3 million DMs each. Hence the F-104 became known as Witwenmacher ("The Widowmaker") in West Germany. Some operators lost a large proportion of their aircraft through accidents, although the accident rate varied widely depending on the user and operating conditions; the German Air Force and Federal German Navy lost about 30% of aircraft in accidents over its operating career, and Canada lost 46% of its F-104s (110 of 235). The Spanish Air Force, however, lost none.
The Class A mishap rate (write off) of the F-104 in USAF service was 26.7 accidents per 100,000 flight hours as of June 1977  (30.63 through the end of 2007), the highest accident rate of any USAF Century Series fighter. By comparison, the mishap rate of the Convair F-102 Delta Dagger was 14.2/100,000 (13.69 through 2007), and the mishap rate for the North American F-100 Super Sabre was 16.25/100,000.
Notable U.S. Air Force pilots who lost their lives in F-104 accidents include Maj. Robert H. Lawrence Jr. and Capt. Iven Kincheloe. Civilian (former USAAF) pilot Joe Walker died in a midair collision with an XB-70 Valkyrie while flying an F-104. Chuck Yeager was nearly killed in December 1963 when he lost control of an NF-104A during a high-altitude record-breaking attempt; he lost the tips of two fingers and was hospitalized for a long period with severe burns after ejecting from the aircraft.
On 2 November 1959, an F-104 crashed into a house in suburban Dayton, Ohio, killing two young girls and critically burning their mother; the pilot had ejected to safety a half-mile away from the crash site.
The F-104 was the first aircraft to simultaneously hold the world speed and altitude records. On 7 May 1958, U.S. Air Force Maj. Howard C. Johnson, flying YF-104A 55-2957, broke the world altitude record by flying to 91,243 feet (27,811 m) at Edwards AFB. On 16 May 1958, U.S. Air Force Capt. Walter W. Irwin, flying YF-104A 55-2969, set a world speed record of 1,404.19 miles per hour (2,259.82 km/h) over a course 15 miles (24 km) long at Edwards AFB. Flying F-104A 56-0762 over NAS Point Mugu, California, U.S. Air Force Lt. William T. Smith and Lt. Einar Enevoldson set several time-to-climb records on 13 and 14 December 1958:
- 3,000 metres (9,800 ft) in 41.85 seconds
- 6,000 metres (19,700 ft) in 58.41 seconds
- 9,000 metres (29,500 ft) in 81.14 seconds
- 12,000 metres (39,400 ft) in 99.90 seconds
- 15,000 metres (49,200 ft) in 131.1 seconds
- 20,000 metres (65,600 ft) in 222.99 seconds
- 25,000 metres (82,000 ft) in 266.03 seconds
On 14 December 1959, U.S. Air Force Captain "Joe" B. Jordan, flying F-104C AF Ser. No. 56-0885 at Edwards AFB, set a new world altitude record of 103,389 feet (31,513 m), in the process becoming the first aircraft to cross the 100,000-foot threshold. He also set a 30,000-metre (98,400 ft) time-to-climb record of 904.92 seconds. (The lower-altitude records were surpassed in February 1962 by the Northrop T-38 Talon, and soon after all of the time-to-climb records were broken by the F-4 Phantom.) U.S. Air Force Maj. Robert W. Smith, flying NF-104A 56-0756, set an unofficial world altitude record of 118,860 feet (36,230 m) on 15 November 1963, and on 6 December 1963 he flew the same aircraft to another unofficial altitude record of 120,800 feet (36,800 m).
Jacqueline Cochran flew TF-104G N104L to set three women's world's speed records: On 11 May 1964, she averaged 1,429.3 miles per hour (2,300.2 km/h) over a 15–25 km (9.3–15.5 mi) course, on 1 June she flew at an average speed of 1,303.18 miles per hour (2,097.26 km/h) over a 100 km (62 mi) closed-circuit course, and on 3 June she recorded an average speed of 1,127.4 miles per hour (1,814.4 km/h) over a 500 km (310 mi) closed-circuit course.
Lockheed test pilot Darryl Greenamyer built an F-104 out of parts he had collected. The aircraft, N104RB, first flew in 1976. On 2 October of that year, trying to set a new low-altitude 3 km (1.9 mi) speed record, Greenamyer averaged 1,010 miles per hour (1,630 km/h) at Mud Lake near Tonopah, Nevada. A tracking camera malfunction eliminated the necessary proof for the official record. On 24 October 1977, Greenamyer flew a 3 km (1.9 mi) official FAI record flight of 988.26 miles per hour (1,590.45 km/h).
On 26 February 1978, Greenamyer made a practice run for a world altitude record attempt. After the attempt, he was unable to get a lock light on the left wheel; after multiple touch-and-go tests at an Edwards Air Force Base runway, he determined that it was not safe to land. He ejected, and the N104RB crashed in the desert.
- Two prototype aircraft equipped with Wright J65 engines (the J79 was not yet ready); one aircraft equipped with the M61 cannon as an armament test bed. Both aircraft were destroyed in crashes.
- 17 pre-production aircraft used for engine, equipment, and flight testing.
- A total of 153 initial production versions were built. The F-104A was in USAF service from 1958 through 1960, then transferred to the Air National Guard until 1963. At that time they were recalled by the USAF Air Defense Command for the 319th and 331st Fighter Interceptor Squadrons. Some were released for export to Jordan, Pakistan, and Taiwan, each of whom used it in combat. The 319th F-104As and Bs were re-engined in 1967 with the J79-GE-19, which provided 17,900 lbf (79.6 kN) of thrust in afterburner; service ceiling with this engine was in excess of 73,000 ft (22,000 m). In 1969, all the F-104A/Bs in ADC service were retired. On 18 May 1958, an F-104A set a world speed record of 1,404.19 mph (2,259.82 km/h).
- Three demilitarized versions with an additional 6,000 lbf (27 kN) Rocketdyne LR121/AR-2-NA-1 rocket engine, used for astronaut training at altitudes up to 120,800 ft (36,800 m).
- A total of 22 F-104As converted into radio-controlled drones and test aircraft.
- Tandem two-seat, dual-control trainer version of F-104A. A total of 26 built, the F-104B had an enlarged rudder and ventral fin, no cannon, and reduced internal fuel, but otherwise combat-capable. A few were supplied to Jordan, Pakistan, and Taiwan.
- Fighter-bomber version for USAF Tactical Air Command, with improved fire-control radar (AN/ASG-14T-2), one centerline and two wing pylons (for a total of five), and ability to carry one Mk 28 or Mk 43 nuclear weapon on the centerline pylon. The F-104C also had in-flight refuelling capability. On 14 December 1959, an F-104C set a world altitude record of 103,395 ft (31,515 m) (31,515 m). 77 built.
- Dual-control trainer version of the F-104C. 21 built.
- Dual-control trainer version of the F-104J for the Japanese Air Self-Defense Force. 20 built by Lockheed and assembled by Mitsubishi. After their retirement in Japan, the U.S. delivered some F-104J/DJs to the Taiwanese Air Force.
- Dual-control trainers based on F-104D, but using the upgraded engine of the F-104G. No radar, and not combat-capable. Produced as interim trainers for the German Air Force. All 30 F-104F aircraft were retired by 1971.
- 1,122 aircraft of the main version produced as multi-role fighter-bombers. Manufactured by Lockheed, and under license by Canadair and a consortium of European companies that included Messerschmitt/MBB, Dornier, Fiat, Fokker, and SABCA. The type featured strengthened fuselage and wing structure, increased internal fuel capacity, an enlarged vertical fin, strengthened landing gear with larger tires, and revised flaps for improved combat maneuvering. Upgraded avionics included a new Autonetics NASARR F15A-41B radar with air-to-air and ground mapping modes, the Litton LN-3 Inertial Navigation System (the first on a production fighter), and an infrared sight.
- 189 tactical reconnaissance models based on the F-104G, usually with three KS-67A cameras mounted in the forward fuselage in place of the internal cannon.
- 220 combat-capable trainer versions of the F-104G; no cannon or centerline pylon, and reduced internal fuel. One aircraft was used by Lockheed as a demonstrator with the civil registration number N104L, and was flown by Jackie Cochran to set three women's world speed records in 1964. This aircraft later served in the Netherlands. A pair of two-seat TF-104Gs and a single-seat F-104G joined the NASA Dryden inventory in June 1975.
- Projected export version based on the F-104G with simplified equipment and optical gunsight. Cancelled prior to construction.
- Specialized interceptor version of the F-104G for the Japanese ASDF, built under license by Mitsubishi for the air-superiority role, armed with cannon and four Sidewinders; no strike capability. Some were converted to UF-104J radio-controlled target drones and destroyed. A total of 210 were built, three by Lockheed, 29 by Mitsubishi from Lockheed-sourced components, and 178 by Mitsubishi. After retired in Japan, U.S. delivered some 104J/DJs to the airforce of Taiwan.
- Three F-104Gs were delivered to NASA in 1963 for use as high-speed chase aircraft. One, piloted by Joe Walker, collided with an XB-70 on 8 June 1966.
- 246 Italian versions were produced by FIAT (one aircraft crashed prior to delivery and is often not included in the total number built). Forty aircraft were delivered to the Turkish Air Force and the rest to the Italian Air Force (Aeronautica Militare Italiana). The F-104S was upgraded for the interception role, adding the NASARR R-21G/H radar with moving-target indicator and continuous-wave illuminator for semi-active radar homing missiles (initially the AIM-7 Sparrow), two additional wing and two underbelly hardpoints (increasing the total to nine), the more powerful J79-GE-19 engine, and two additional ventral fins to increase stability. The M61 cannon was sacrificed to make room for the missile avionics in the interceptor version, but retained for the fighter-bomber variants. Typically two Sparrow and two (and sometimes four or six) Sidewinder missiles were carried on all the hardpoints except the central (underbelly), or up to seven 750 lb (340 kg) bombs (normally two to four 500–750 lb [230–340 kg]). The F-104S was cleared for a higher maximum takeoff weight, allowing it to carry up to 7,500 lb (3,400 kg) of stores; other Starfighters had a maximum external load of 4,000 lb (1,800 kg). Range was up to 780 mi (1,260 km) with four tanks.
- F-104S-ASA (Aggiornamento Sistemi d'Arma – "Weapon Systems Update")
- 150 upgraded F-104Ss equipped with the Fiat R21G/M1 radar with frequency hopping and look-down/shoot-down capability, new IFF system and weapon delivery computer, and provision for the AIM-9L all-aspect Sidewinder and Selenia Aspide missiles. It was first flown in 1985.
- F-104S-ASA/M (Aggiornamento Sistemi d'Arma/Modificato – "Weapon Systems Update/Modified")
- 49 airframes upgraded in 1998 to ASA/M standard with GPS, new TACAN and Litton LN-30A2 INS, refurbished airframe, and improved cockpit displays. All strike-related equipment was removed. The last Starfighters in combat service, the F-104S-ASA/M was withdrawn in December 2004 and temporarily replaced by the F-16 Fighting Falcon, while awaiting Eurofighter Typhoon deliveries.
- 200 Canadian-built versions, built under license by Canadair. Optimized for both nuclear strike and 2-stage-to-orbit payload delivery, the CF-104 had NASARR R-24A radar with air-to-air modes, cannon deleted (restored after 1972), additional internal fuel cell, and Canadian J79-OEL-7 engines with 10,000 lbf (44 kN)/15,800 lbf (70 kN) thrust.
- 38 dual-control trainer versions of CF-104, built by Lockheed, but with Canadian J79-OEL-7 engines. Some were later transferred to Denmark, Norway, and Turkey.

Notable appearances in media
The Starfighter was called the "missile with a man in it", a name swiftly trademarked by Lockheed for marketing purposes, and the press coined the F-104 the Widowmaker due to its high accident rate, but neither were used in service. The term Super Starfighter was used by Lockheed to describe the F-104G in marketing campaigns, but fell into disuse.
In service, it earned a host of nicknames among its users:
- American pilots called it the Zipper or Zip-104 because of its prodigious speed.
- The Japan Air Self-Defense Force called it Eiko (Kanji: 栄光, "Glory").
- In Germany it earned several less-charitable names due to its high accident rate, a common name being Fliegender Sarg ("Flying Coffin"). It was also called Witwenmacher ("Widowmaker"), or Erdnagel ("ground nail"), the official military term for a tent peg.
- The Pakistani Air Force called it Badmash ("Hooligan").
- Among Italian pilots its spiky design earned it the nickname Spillone ("Hatpin"), along with Bara volante ("Flying Coffin").
- Among the Norwegian public and Royal Norwegian Air Force it was affectionately known as Vestfjordoksen ("the Vestfjord bull"), due to the immense roar of the aircraft based in Bodø, at the southern end of Vestfjorden.
- In the Canadian Forces, the aircraft were sometimes referred to as the Lawn Dart and the Aluminium Death Tube due to the high operational losses of 40% of airframes, and Flying Phallus due to its shape. It was affectionally called the Silver Sliver, the Zipper, or Zip, but normally the Starfighter or simply the 104 (one-oh-four).
- NASA's F-104B Starfighter N819NA acquired the nickname Howling Howland due to the unique howling sound of its engine at certain throttle settings.
