CH-37 Mojave

CH-37 Mojave. . , The Army's Sikorsky CH-37 had its origins in an aircraft developed to serve as an assault helicopter for the Marine Corps. The first prototype flew in 1953 with the Marines purchasing sixty aircraft known as the HR2S. The Army evaluated the prototype in 1954 and soon ordered ninety-four CH-37s.

At the time of its delivery, the CH-37 was the largest helicopter in the western world. The two 2100 hp piston engines were mounted in outboard pods that also contained the retractable landing gear. The fuselage was thus left free for cargo which could be loaded and unloaded through large clamshell doors in the nose.

The CH-37 cargo compartment could accommodate two jeeps or a 105mm howitzer. It could also carry twenty six troops or twenty four litters. Several CH-37s deployed to Vietnam where their primary role as aircraft recovery.

The CH-37 was replaced in the late 1960s by the new CH-54 Tarhe and subsequent CH-47 Chinook, both employing the newer turboshaft engines that rendered the larger and heavier piston engines obsolete.

The CH-37B Mojave helicopter on display is a combination of parts from several helicopters. The helicopter was assembled in Arizona and then flown to Fort Eustis as it was too large to ship by truck. The helicopter was later given the markings of the 4th Transportation Company, which in 1958 became the Army's first medium helicopter company when it fielded the CH-37.
