Design

Like all

kilowatts; 3,900 shaft horsepower), two Siemens-Schuckert GU365/30 double-acting electric motors each providing 5,000 PS (3,700 kW; 4,900 shp), and two Siemens-Schuckert silent running GV232/28 electric motors each providing 226 PS (166 kW; 223 shp).[5]

The submarine had a maximum surface speed of 15.6 knots (28.9 km/h; 18.0 mph) and a submerged speed of 17.2 knots (31.9 km/h; 19.8 mph). When running on silent motors the boat could operate at a speed of 6.1 knots (11.3 km/h; 7.0 mph). When submerged, the boat could operate at 5 knots (9.3 km/h; 5.8 mph) for 340 nautical miles (630 km; 390 mi); when surfaced, she could travel 15,500 nautical miles (28,700 km; 17,800 mi) at 10 knots (19 km/h; 12 mph).

2 cm (0.79 in) C/30 anti-aircraft guns. She could carry twenty-three torpedoes or seventeen torpedoes and twelve mines. The complement was five officers and fifty-two men.[5]

Fate

On 3 May 1945, while on her way to Norway, U-2503 was in the Great Belt, near the Ömo Light Tower, when she was caught and attacked on the surface by Royal Air Force (RAF) Bristol Beaufighters of 236 Squadron and 254 Squadron, part of the Banff Strike Wing. U-2503 was struck in the area of the conning tower by at least one rocket, which caused severe damage and killed several crewmen and Kapitänleutnant Karl-Jürg Wächter. U-2503, burning badly, was beached off of Omø, with 13 dead and an unknown number of survivors. The remaining crew landed ashore and scuttled the boat with explosives the next day.
