The 37mm Gun M1 was an anti-aircraft autocannon developed in the United States. It was used by the US Army in World War II.
In addition to the towed variant, the gun was mounted, with two M2 machine guns, on the M2/M3 half-track, resulting in the T28/T28E1/M15/M15A1 series of multiple gun motor carriages.

Two gun units were coupled to the M5 gun director using the M1 remote control system. The system was powered by the M5 generating unit. If the remote system was inoperative the M5 sighting system was used.
The M1 utilized fixed ammunition. Projectiles were fitted with a 37×223mmSR cartridge case.
