  • Sizeable warhead of ~360 kg TNT equivalent can deal a considerable damage against enemy ships
  • Fast travel speed when not equipped with torpedo mode, long range when equipped


  • Average performance compared to its contempolaries
  • Short range without torpedo mode, equipping the modification will significantly reduce its travel speed


German Torpedoes manufactured prior to the end of World War II were designated as to their diameter, length and propulsion. Modifications were usually, but not always, denoted by T numbers. Length was to the nearest meter. For example, the designation G7a meant that the torpedo was 53.3 cm (21") in diameter, was about 7 meters long and had an wet heater motor.

Diameter Propulsion
F 45 cm D Dampftorpedo (wet heater, World War I)
G 50 or 53.3 cm a Air/steam (wet heater, World War II)
H 60 cm e Electric
J 70 cm u Hydrogen peroxide
M 75 cm

This torpedo is using SW39a explosive. Number indicating year of adaption. It was composed of TNT, Hexinit (HND), Ammonium Nitrate and Aluminum. Content of aluminum powder was increased from previous versions (SW36 and SW39) to increase shock wave.
