Kriegsmarine U- Boat Type VIIA
If any submarine type could be considered the best fighting submarine, it has to be the German Type VII. This type had very limited crew comforts, was built strictly to hunt and kill, and there were more Type VII German U-boats built than any other type of any navy.
Type VII boats, designed in 1933-1934, were the first of a new generation of German attack U-boats, they were popular with their crews and very agile on the surface. They also had a much more powerful striking power than the smaller Type II`s. They had 5 torpedo tubes (4 at the bow) and would carry 11 torpedoes onboard or 22 TMA mines. They also had the effective 88mm fast-firing deck gun with about 160 rounds of ammunition.
