The Kaiten was a manned fast torpedo intended to be piloted directly into its target, in practice becoming a suicide weapon. As such, its operation differed substantially from the human torpedo as used by Italian, British and German militaries. Russia/USSR After 1945 Siren. It is or was made after 1945. It is longer than a British or Italian Chariot because it has 2 warheads. It has 2 riders. It was designed to exit through a submarine's torpedo tube. See Russian commando frogmen. United States After 1945 There are pictures and descriptions of modern US Chariot-like underwater frogman-carriers used by SEALs and a fast surface boat that can submerge, here: Swimmer Delivery Vehicle (SDV) SEAL Delivery Vehicle Swimmer Transport Device (STD) Other countries Argentina Argentina developed manned torpedoes and special mini-submarines in the 1950s, the latter with a torpedo attached under the two-men crew. Their crews were trained by , a former member of the Italian Decima MAS. Poland In Poland, in the months before the outbreak of the Second World War, a number of volunteers came forward to pilot torpedoes against German warships. A Bureau of Living torpedoes was set up to organize and train these volunteers, and prepare suitable equipment, but nothing had come to fruition before the German invasion and occupation. Yugoslavia The Yugoslav Navy did not have manned torpedoes, but frogmen used the underwater device called R-1 Diver for a variety of missions, including: mine clearance, infiltration, clandestine surveillance and security, and assault missions on enemy shipping and naval objects. These small apparatuses were relegated to the navies of Croatia (HRM) (1991) and Montenegro (2007). Museums Original SLCs (Siluri Lenta Corsa or "Maiale") are displayed at the Naval History Museum Venice, Italy. There are three chariots on public view in Eden Camp Museum near Malton, North Yorkshire in England: A restored original British Mark II, which was found derelict in a scrapyard in Portsmouth. In this design, the two riders sat back to back. A working chariot that was made in 1992 in Milton Keynes with approximately the outside appearance of a British wartime Mark I, but with differing internal working parts. It has been filmed in action for the television. It has a dummy warhead. It was last used in 2006. A replica Italian maiale made soon after 1945 by the same Italian firm (Caproni) who made the wartime maiali. As at July 2008 this was
