1914-15: 2nd Flotilla, Portsmouth
What appears to have escaped the eyes of researchers so far is that the first diesel-engined submarine in the Royal Navy was HMS A.13X. Launched at Barrow in 1905. The boat was fitted with what is described now as "a heavy oil engine." It was in fact a diesel engine designed and built by Vickers.
Ruston-Hornsby, then Hornsby, had designed an oil engine but it was rejected on account of being "too heavy". The Vickers design was used instead. Yet diesel propulsion was not generally used until the advent of the D class boats.

In the last days of WWII, Germany, desperate for any last gasp to defeat the allied powers, looked to their last remaining weapons and soldiers. The German Navy and the last remaining U-Boats, were brought together for one last mission, to attack the United States Homeland,
Operation Seawolf. Captain Hans Kessler, a grizzled submarine commander from both World Wars, is called into service to make the mission a success and help turn the tide of the war.
