The CH-37 Series Mojave medium cargo helicopter was initially procured in 1956 from Sikorsky (Model S-56) The CH-37A or CH-37B, with a crew of three, was a large medium lift transport helicopter with clam shell doors in the nose that provided access to a cargo compartment. The cargo hold could accommodate two jeeps, a light truck, or a 105mm howitzer (see photo loading M37 truck below). When configured for personnel, the Mojave could carry 26 troops or 24 litters in the MedEvac role.
The CH-37 had a single five-bladed main rotor and a metal four-bladed tail rotor. The CH-37A was powered by two Pratt & Whitney R-2800-50 1900 hp pistons engines while the CH-37B was powered by two Pratt & Whitney R-2800-54 2100 hp piston engines.
The Mojave was used by Army and Marine Corps in Korea and Vietnam for aircraft recovery, cargo, and artillery transport as well as MedEvac. The CH-37 was replaced by the CH-47 Chinook.
