The first work on the design of heavy military transport helicopter model Sikorsky CH-37 Mojave, started by American engineers in the early 50-ies of the last century. The initiator of this project was the beginning of the US military command, that there is a strong need to use multi-purpose helicopters, high load capacity, capable to transport on its board of military and transportation of heavy and oversized cargo.

Despite the fact that their first flight of the aircraft model Sikorsky CH-37 Mojave has made already 1953 year, the public at large aircraft project was presented only 1956 year, while, in spite of the relatively high potential of this helicopter, his official operation has been completed by the end of 60-x, which actually refers to the fact that the aircraft does not meet the needs of the US army.

One of the key negative aspects of helicopter Sikorsky CH-37 Mojave is its short range of flight, it is not possible to efficiently operate the aircraft. Even with the introduction of modifications and attempts to install additional fuel tanks, the helicopter could not overcome the distance over 420 kilometers. In addition, the rather large size of the aircraft, made the military-transport helicopter low maneuverable, which also gave certain difficulties in its operation.

On board the aircraft Sikorsky CH-37 Mojave can accommodate up to 29 people, including three crew members and 26-equipped troops. If necessary, the helicopter could carry also the transport on its board and cargo total weight of up to 4,5 tons, which was a very acceptable figure for a given aircraft.

Initially it was assumed. With the helicopter can also receive and combat purpose, in particular, provided for the possibility of its use as an anti-submarine, anti-ship, or means, however, low maneuverability and a small range of flight, was not allowed to exploit it for such purposes.

The Sikorsky CH-37 Mojave helicopter is equipped with two radial engines of the Pratt & Whitney R-2800-54 Double Wasp brand, each of which has its own 2100 hp thrust, which provides the aircraft with a high payload, however, despite this fact, the maximum flight speed of the aircraft of this model is limited to 210 km / h.
