Combat experience in 1941-1942 showed that the troops needed a mobile anti-aircraft system capable of escorting mechanized columns and protecting against enemy aircraft. Development of the new vehicle began in 1942. The first prototype of the T65 self-propelled artillery piece was created using the M5A1 light tank chassis, though it was replaced during trials with the M24 light tank's more modern version.
