German submarine U-535 was a Type IXC/40 U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 6 March 1942 at the Deutsche Werft yard at Hamburg, launched on 8 October 1942, and commissioned on 23 December 1942 under the command of Kapitänleutnant Helmut Ellmenreich. After training with 4th U-boat Flotilla in the Baltic Sea, U-535 was transferred to 10th U-boat Flotilla for front-line service. U-535 completed one patrol, but did not sink any ships.

Design

German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-535 had a displacement of 1,144 tonnes (1,126 long tons) when at the surface and 1,257 tonnes (1,237 long tons) while submerged. The U-boat had a total length of 76.76 m (251 ft 10 in), a pressure hull length of 58.75 m (192 ft 9 in), a beam of 6.86 m (22 ft 6 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.67 m (15 ft 4 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 shaft horsepower (1,010 PS; 750 kW) for use while submerged. She had two shafts and two 1.92 m (6 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 18.3 knots (33.9 km/h; 21.1 mph) and a maximum submerged speed of 7.3 knots (13.5 km/h; 8.4 mph). When submerged, the boat could operate for 63 nautical miles (117 km; 72 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 13,850 nautical miles (25,650 km; 15,940 mi) at 10 knots (19 km/h; 12 mph). U-535 was fitted with six 53.3 cm (21 in) torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one 10.5 cm (4.13 in) SK C/32 naval gun, 180 rounds, and a 3.7 cm (1.5 in) SK C/30 as well as a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of forty-eight.

Service history

U-535 sailed from Kiel on 25 May 1943 on her first and only war patrol in the north Atlantic.

On 8 June at about 14:00, the U-boat was attacked with depth charges by a Hudson light bomber from No. 269 Squadron RAF, close to Convoy SC 132. A follow-up attack by another Hudson from the same squadron was aborted when the depth charges failed to release in two attack runs. The aircraft was damaged by the U-boat's flak, and the pilot warned an arriving United States Navy Catalina patrol bomber of Squadron VP-84 that the boat would stay up and fight, so the flying boat shadowed U-535 until it escaped at dusk.

Sinking

At 16:55 on 5 July 1943, a group of three inbound U-boats; U-170, U-535 and U-536 were attacked by a British Liberator maritime reconnaissance aircraft of No. 53 Squadron RAF, north-east of Cape Finisterre, Spain. The U-boats evaded the first attack, and U-536 was strafed in the second. U-536 gave the signal to crash-dive, but for unknown reasons U-535 remained on the surface. Despite hitting the aircraft with her AA guns, the U-boat was straddled by eight depth charges and sank with all hands in position 43°38′N 09°13′W. Damaged and with one crewman wounded, the aircraft immediately left the area and returned to base.
