The M53 Self-Propelled Assault Gun was developed via automotive components taken from existing M46 and M47 Patton medium tanks appearing during the Cold War. The M53, with its 155mm main gun, provided long-range fire support to allied positions and its self-propelled tracked nature ensured that it could keep pace with mechanized formations and provide cross-country capabilities. The series was adopted in 1952 and went on to see service with both the United States Army and Marine Corps. Production of the type was handled through Pacific Car & Foundry Company.
