The Dodge M37 (G-741) was a ¾ ton four-wheel drive truck. It superseded the Dodge WC-51 and WC-52 trucks in US service and was used extensively by the United States armed forces during the Korean war. A number of variants were produced with slightly different configurations: the M42 command truck, V41 telephone maintenance vehicle and M43 ambulance.

Development

The six prototypes of the vehicle were produced in early to mid 1950, with the first pre-production pilot vehicle rolling off the assembly line on 14 December 1950 . Production began in earnest in January of 1951, with approximately 11,000 vehicles produced by the end of the year. By mid-1954 63,000 of the vehicles had been produced. In 1958 a number of modifications to the design resulted in the new vehicles being designated as M37B1. From mid-1958 until the end of production 47,600 M37B1 vehicles were produced. Approximately 4,500 Canadian M37CDNs were also produced between 1951 and 1955.

In total between 1951 and 1968 115,000 M37s were produced.
