Ordnance QF 6 Pounder - Self-propelled Mounts

Self-propelled Mounts

Tank gun versions of the 6-pounder were used in Crusader III, Cavalier, Centaur I and II, Cromwell I to III, Valentine VIII to X and Churchill III and IV, and also in the Canadian Ram Mk II and the experimental American Light Tank T7E2. The Deacon and the experimental Alecto Mk II self-propelled guns also mounted the 6-pounder. Another experimental vehicle armed with the 6-pounder was a Firefly tank destroyer, based on the Morris Light Reconnaissance Car.

The only mass-produced vehicle mounting the 57 mm M1 was the M3 Half-track based 57mm Gun Motor Carriage T48 (also known by its Soviet designation SU-57). The production of the T18E2 armored car, also known as Boarhound, was stopped after 30 units were built. A project of tank destroyer armed with the M1—the 57 mm Gun Motor Carriage T49—was cancelled after a single pilot vehicle was built. Similarly, the wheeled 57 mm Gun Motor Carriage T44, based on Ford 4×4 ¾ ton cargo carrier chassis, was cancelled after a brief testing.
