The Sikorsky S-56 was developed to meet a U.S. Marine Corps requirement for a large assault helicopter.  The S-56 had two nacelles on either side of the fuselage that held both the piston engines and retractable landing gear.  The prototype first flew in 1953.

The S-56 was delivered to the Marine Corps as the HR2S.  The U.S. Army designated their version the H-37 Mojave.  Later versions could lift 11,000 lbs of cargo or 36 fully armed troops.
