The Kind ? U-boat, designed in key during 1933?1944, had been a brand new generation of German attack submarines. They'd a much more effective striking force compared to Type ?.They had five torpedo tubes, four into the bow and something astern and might carry eleven torpedoes onboard or 22 TMA (23 TMB) mines. Additionally they had 88mm fast-firing deck weapon and 20mm AA gun. At the start of the war, the 88mm deck weapon ended up being very useful in sinking vendor ships, enabling the more expensive torpedoes become saved for bigger and much more valuable targets. These Type ? U-boats were the spark plug of �Wolf Pack�. Their manufacturing was in big people. On top of that, German Navy suffered the big losses of this force, losing 784 U-boat, which 519 had been Type ? U-boat.?
