About the M37 'Tanker'

The M37 would enter service in 1955 and would be issued as the primary medium machine gun in M48 and M50 Patton tanks. Built as a more adaptable replacement for the M1919 in armored roles, the M37 featured dual-feed options and could be fired manually, or from a solenoid fire control unit. Lighter versions, such as the M37C, would be mounted in helicopter gunships. Due to the US military’s replacement of the .30-06 cartridge for the new 7.62mm NATO round, some variants of the M37 (M37E1) would be converted to the new cartridge as a stop-gap measure. Ultimately, the M37 would be replaced by the M73 in 1959. Most transferable examples are post-war sideplate builds using a mix of surplus parts.
