The submarine was laid down on 3 November 1941 at the Friedrich Krupp Germaniawerft yard at Kiel as yard number 659, launched on 20 August 1942, and commissioned on 3 October under the command of Oberleutnant zur See Robert Schetelig.
After training with the 5th U-boat Flotilla at Kiel, U-229 was transferred to the 6th U-boat Flotilla, (which was based at Saint-Nazaire on the French Atlantic coast), on 1 March 1943, for front-line service. In three war patrols the U-boat sank two merchant ships, totalling 8,352 gross register tons (GRT) and damaged another of 3,670 GRT.
She was sunk by a British warship in September 1943.
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-228 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph). When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-228 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and an anti-aircraft gun. The boat had a complement of between forty-four and sixty.
She sank the British freighter Nailsea Court - part of convoy SC 121 on 10 March 1943 southeast of Cape Farewell, Greenland. In the same attack she damaged the British freighter Coulmore (this ship was salvaged and returned to service in July 1943).
She then sank the Swedish Vaalaren in the same vicinity on 5 April. There were no survivors.
U-229 arrived at St. Nazaire on 17 April.
The boat's second foray commenced with her departure from St. Nazaire on 11 May 1943. On the 17th, west of the Bay of Biscay, she was attacked by a Catalina flying boat of No. 190 Squadron RAF. The damage inflicted was such that she was forced to return to France, arriving in Bordeaux on 7 June.
Having moved from Bordeaux to La Pallice in early August 1943, the boat departed the latter port on the 31st.
She was sunk on 22 September 1943 south-east of Cape Farewell, Greenland in position Coordinates: , by depth charges, gunfire and ramming by the British destroyer HMS Keppel. All 50 hands were lost.
U-229 took part in four wolfpacks, namely.
- Neuland (4–6 March 1943)
- Ostmark (6–11 March 1943)
- Stürmer (11–16 March 1943)
- Leuthen (15–23 September 1943)
