Historical reference

The CH-53 Sea Stallion (Sikorsky S-65) is a family of heavy-lift transport helicopters designed and built by Sikorsky Aircraft. Originally developed for use by the United States Marine Corps, it is currently in service with Germany, Iran, Israel, and Mexico. The United States Air Force operated the HH-53 "Super Jolly Green Giant" during the late– and post – Vietnam-War era, updating most of them as the MH-53 Pave Low.

The dimensionally-similar CH-53E Super Stallion is a heavier-lifting, improved version designated S-80E by Sikorsky. Its third engine makes it more powerful than the Sea Stallion, which it has replaced in the heavy-lift mission.

In 1960, the United States Marine Corps began to seek a replacement for their HR2S piston-powered helicopters. On 27 January 1961, the Marine Corps began working with the U.S. Army, Navy, and Air Force on the "Tri-Service VTOL transport", which would eventually emerge as the Vought-Hiller-Ryan XC-142A tiltwing. The design became more elaborate and the program stretched out, causing the Marines to drop out when they decided they would not receive a working machine in a satisfactory timeframe. In particular, there were concerns that the high levels of downwash produced by the XC-142A would render shipborne operations impractical. In the end, the XC-142A, although a very innovative and capable machine, never entered production.

In March 1962, the United States Navy's Bureau of Naval Weapons, acting on behalf of the Marines, issued a request for a "Heavy Helicopter Experimental / HH (X)". The specifications dictated a load capability of 8,000 pounds (3,600 kg) with an operational radius of 100 nautical miles (190 km; 120 mi) at a speed of 150 knots (280 km / h; 170 mph). It was also specified to possess a higher top speed and greater lifting capacity than existing helicopters while also having a lower empty weight than preceding designs as well. The HH (X) was to be used in the assault transport, aircraft recovery, personnel transport, and medical evacuation roles. In the assault transport role, it was to be mostly used to haul heavy equipment instead of troops.

In response, Boeing Vertol offered a modified version of the CH-47 Chinook; Kaman Aircraft offered a development of the British Fairey Rotodyne compound helicopter; and Sikorsky offered what to a scaled-up version of the S-61R, with twin General Electric T64 turboshaft engines and the dynamic system of the S-64 / CH-54, to be designated the S-65. Kaman's proposal quickly died when the British government dropped its backing of the Rotodyne program. Competition between Boeing Vertol and Sikorsky was intense, with the Chinook having an advantage because it was being acquired by the United States Army. During July 1962, it was announced that Sikorsky's bid had been selected as the winner on account of various considerations, including cost, technical factors, and production capability. However, a contract was not immediately forthcoming due to budgetary limitations.
