German submarine U-2516

German submarine U-2516 was a Type XXI U-boat (Elektroboot) of Nazi Germany's Kriegsmarine during the Second World War. She spent the war as a trials vessel and was damaged beyond repair by a British air raid while docked and scrapped in Kiel, Germany.

Construction
The U-2516 was laid down on 3 August 1944 at the Blohm & Voss shipyard in Hamburg, Germany. She was launched on 27 September 1944 and commissioned on 24 October 1944 under the command of Oberleutnant zur See der Reserve Fritz Kallipke with her U-boat emblem being a red deer.

When she was completed, the submarine was 76.70 m long overall (o/a), with a beam of 8 m and a draught of 6.32 m. She was assessed at 1819 t submerged and 1621 t when at the surface. The submarine was powered by two MAN SE supercharged six-cylinder M6V40/46KBB diesel engines each producing a total of 4000 PS for use while surfaced and two Siemens-Schuckert GU365/30 double-acting electric motors each providing a total of 5000 PS and two Siemens-Schuckert silent running GV232/28 electric motors each providing 226 PS for use while submerged. The submarine had a maximum surface speed of 15.6 kn and a maximum submerged speed of 17.2 kn with a speed of 6.1 kn when running on silent motors. When submerged, the U-boat could operate for 340 nmi at 5 kn and when surfaced, she could travel 15.5000 nmi at 10 kn.

The submarine was fitted with six 53.3 cm torpedo tubes (All fitted at the bow) and 23 torpedoes or 17 torpedoes and 12 mines. The boat was also equipped with four 2 cm C/30 anti-aircraft guns. The submarine had a complement of five officers and 52 men.

Service history
U-2516 did not undertake any combat patrols and was instead assigned as a trials boat to the 31st U-boat Flotilla from 24 October 1944 onward always serving under the same commander until her career's end.

The U-2516 was docked at drydock number 1 in Kiel, Germany, on 9 April 1945 when the docks were attacked at 22:30 by British RAF bombers from Bomber Command's 1st, 3rd and 8th Groups. There were three men aboard U-2516 at the time of the attack working in the engine room. Two of them were killed when several bombs hit U-2516, which had also damaged her beyond repair ending her war career. Also destroyed by the bombing of Kiel that night was the GS U-1227. The wreck of U-2516 lay where she was sunk until she was scrapped after the war's end.
