Type 53 is the common name for a family of 53 cm torpedoes manufactured in Russia, starting with the 53-27 torpedo and continuing to the modern UGST. With the exception of the UGST which uses Mark 48 style monopropellants, Soviet 53 cm torpedoes generally use electric power, or kerosene mixed with various oxidizers for propulsion. Russian torpedoes are often named descriptively for their characteristics - examples include "acoustic homing" or "electric torpedo", all in Russian acronyms.
