The V-80 (German: Versuchs-U-Boot V 80) was a 1939 German Navy 76-ton experimental submarine and the only representative of the German Type V design.
The prototype was completed in 1940 in Germaniawerft in Kiel. The 4 man vessel was designed to test the Walter hydrogen peroxide-based turbine propulsion system. Its range was 50 nautical miles (93 km) at 28 knots (52 km/h).
The only earlier attempt in the use of anaerobic air-independent propulsion system was in the 1864 Spanish Ictineo II submarine launched by Spanish inventor Narcís Monturiol i Estarriol, also pioneering the first combustion engine use.
This midget submarine led to the design of the German Type XVII submarine.
