The squadron is a partner to the 381st Intelligence Squadron at the Alaska Mission Operations Center. The unit's mission is to collect, process, analyze, and report signals intelligence on adversary operations, capabilities, and intentions. Additionally, unit personnel provide tactical analytic support to combat units and conduct communications, maintenance, and administrative actions supporting site operations.^[2]

World War II edit

The first predecessor of the squadron was activated in February 1942 as the 138th Signal Intelligence Company at Fort George Wright, Washington. It received it initial cadre on 25 February drawing from the 404th Signal Company, Aviation; 434th Signal Maintenance Company, Aviation and 39th Signal Platoon, Air Base. However, it was April before a substantial number of people were assigned to the company. The company continued training at Fort Wright until May 1943, when they departed for shipment to the Southwest Pacific, Staging through Fort Dix, New Jersey. On 13 May, the company boarded the USAT Uruguay for a monthlong shipment through the Panama Canal to Brisbane, Australia.^[3]

In August 1942, the squadron moved forward to Port Moresby, New Guinea to begin operations.^[4] The squadron continued radio intercept operations of Japanese radio transmissions until VJ Day.

Following the war, the unit was transferred from the Army Signal Corps to the Air Corps and redesignated the 1st Radio Squadron. However, it remained part of Army Security Agency for more than a year after the United States Air Force became independent, not transferring to United States Air Force Security Service until 1 February 1949.

Korean War edit

The squadron remained in Japan after the war with the mission of monitoring Soviet air and air defense signals.^[5] When the North Koreans crossed the 38th parallel and invaded in June 1950, the squadron's commander ordered its vehicles to be laagered on the Johnson Air Base football field in case of a parachute attack on Japan. A detachment of the squadron moved to Korea on 15 July 1950. However Fifth Air Force had established its own ad hoc signals intelligence party near Seoul, which commandeered the 1st Squadron's equipment. However, additional mobile radio intercept detachments began arriving before the end of the year.^[6]

In March 1951, squadron operators in Japan began picking up voice communications in Russian between ground controllers and Mikoyan-Gurevich MiG-15 fighters. By April, the squadron had established a mobile van in central Korea, which passed information on MiGs to the Fifth Air Force tactical air control center, which passed it on to American North American F-86 Sabres, disguising the information to make it appear that it was coming from radar ground stations, even though the radio intercept van could provide warning of Soviet aircraft movements well beyond the range of American radars. Separate stations were established for intercepting enemy morse code signals dealing with both enemy and friendly traffic. After September 1951, these operations were consolidated in Seoul. The information provided by squadron operators has been credited as the major factor in the increased kill ratio of Sabre pilots over the MiG-15 in Korea starting in mid-1951, especially in view of analysis that indicated that by the fall of 1952 90% of MiG pilots in Korea were Russians.^[7] In January 1951, the squadron moved to Misawa Air Base, Japan, where one of the first Elephant Cage high frequency direction finding antenna assemblies was located.^[1][8] The squadron was inactivated in May 1955,^[1] and its mission, personnel and equipment transferred to the 6921st Radio Squadron, Mobile.

6920th Electronic Security Group edit

The second squadron antecedent was activated as the 6920th Security Squadron at Misawa Air Base, Japan in October 1978. When USAF Security Service became Electronic Security Command, the squadron was expanded to group size as the 6920th Electronic Security Group.^[1]

In October 1992, the unit became one of the operational components, with the Naval Security Group Activity, Misawa, a Marine company, and the 750th Military Intelligence Company, in the Misawa Cryptologic Operations Center.^[9]

301st Intelligence Squadron edit

In October 1993, the 1st Radio Squadron (which had been disbanded in 1985), was reconstituted and consolidated with the 6920th Group and the consolidated squadron was named the 301st Intelligence Squadron.^[1] The squadron mission at Misawa was to process time-critical combat information for unified and specified commands and the National Command Authorities. It conducted satellite communications processing and reporting. The 301st provided sensitive communications support to aircraft. It operated and maintained $500,000,000 of electronic equipment.^[10]

After the massive tsunami and devastating earthquake measuring 9.0 on the Richter Scale struck the coast of Japan in 2011, Airmen of the 301st devoted countless hours alongside other Americans and Japanese during Operation Tomodachi by assisting with clean-up and restoration efforts throughout Japan.^[11]

In June 2014, as the Misawa operations center closed and intelligence personnel there were reduced by more than 500 people, the squadron moved from Misawa to Joint Base Elmendorf-Richardson when the intelligence center at Misawa closed.^[11][12]
