German submarine ''U-3524'' was a Type XXI U-boat of Nazi Germany's ''Kriegsmarine'' during World War II. The ''Elektroboote'' submarine was laid down on 8 October 1944 at the Schichau-Werke yard at Danzig, launched on 14 December 1944, and commissioned on 26 January 1945 under the command of ''Kapitänleutnant'' Hans-Ludwig Witt.〔 ''U-3524'' was a brand new, high technology electric boat which could run constantly submerged rather than having to surface to recharge her batteries every day the way submarines until that point had had to do. Unfortunately for the Germans, these advanced vessels were only introduced to the ''Kriegsmarine'' late in 1944, much too late to influence the Battle of the Atlantic, and too late for many of them to serve in an offensive capacity at all. With the end of the war near, training on U-boats had dropped to a minimum due to lack of fuel, falling morale and the effectiveness of allied attacks on U-boat construction and preparation. The exception to this were the new Type XXI boats, which continued to train in the Baltic Sea. ==Design== Like all Type XXI U-boats, ''U-3524'' had a displacement of when at the surface and while submerged. She had a total length of , a beam length of , and a draught length of . The submarine was powered by two MAN SE supercharged six-cylinder M6V40/46KBB diesel engines each providing , two Siemens-Schuckert GU365/30 double-acting electric motors each providing , and two Siemens-Schuckert silent running GV232/28 electric motors each providing . The submarine had a maximum surface speed of and a submerged speed of . When running on silent motors the boat could operate at a speed of . When submerged, the boat could operate at for ; when surfaced, she could travel at . ''U-3524'' was fitted with six torpedo tubes in the bow and four anti-aircraft guns. She could carry twenty-three torpedoes or seventeen torpedoes and twelve mines. The complement was five officers and fifty-two men. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「German submarine U-3524」の詳細全文を読む スポンサード リンク
