The Sort ? U-boat, developed in key during 1933?1944, was in fact a fresh generation of German assault submarines. They'd a far more effective striking force versus Type ?.They had five torpedo pipes, four inside bow and something astern and might carry eleven torpedoes onboard or 22 TMA (23 TMB) mines. Also had 88mm fast-firing deck device and 20mm AA tool. In the very beginning of the war, the 88mm deck gun ended up being beneficial in sinking merchant vessels, allowing the greater high priced torpedoes become conserved for bigger and a lot more valuable goals. These Type ? U-boats was indeed the spark plug towards �Wolf Pack�. Their production was at big users. At precisely the same time, German Navy suffered the top losings using this type of force, losing 784 U-boat, which 519 had been Type ? U-boat.?
