KMS Type XXI

The Type XXI is a German tier 10 submarine in Naval 1945.

History
The Type XXI submarine was a revolutionary Elektroboot submarine built during WW2. Although 118 were made during WW2, only 4 actually combat ready, and only 2 were used in patrols, but never had a chance to prove themselves in combat. They were the first submarines to receive snorkels and had many improvements over their predecessors, which included power-assisted torpedo reloading and greatly improved diving time. After the war, several navies would obtain Type XXIs and use them as a basis for Cold War era submarines, including the US, Soviet Union, Britain, and Sweden.
