Hellmuth Walter

…hydrogen peroxide rocket designed by Hellmuth Walter, the Komet had spectacular performance, but its short range and ineffective cannon armament made it an operational failure. In addition, the propellants were unstable and often exploded on landing.

Hellmuth Walter, a German scientist, developed a turbine propulsion system using oxygen generated by hydrogen peroxide to operate the turbine while submerged. A simplified submarine, the V-80, built in 1940 and propelled by a Walter turbine system, could attain speeds of more than 26 knots…
