Sikorsky CH-53

The Sikorsky CH‑53, developed by Sikorsky Aircraft Corporation, entered service in the late 1960s as a heavy‑lift transport helicopter for the United States Marine Corps. Originating from the earlier S‑64 Skycrane concept, the CH‑53 was designed to replace the CH‑37 Mojave and to provide the Marine Corps with a robust tactical air‑mobility platform capable of moving troops, artillery, and supplies in harsh environments. Early variants, the CH‑53A and CH‑53D, featured twin General Electric T64 turboshaft engines, a six‑blade main rotor, and a spacious cargo bay capable of carrying up to 30,000 pounds internally or externally. In the 1990s, the CH‑53E Super Stallion introduced a third engine, a seven‑blade rotor, and increased lift capacity to over 36,000 pounds, becoming the largest and most powerful helicopter in the U.S. inventory. The latest CH‑53K King Stallion, first flown in 2015, incorporates modern avionics, composite blades, and a 35‑percent payload boost, extending range and survivability. Across more than five decades, the CH‑53 family has proven vital in combat support, humanitarian relief, and disaster response, cementing its role as a cornerstone of heavy‑lift aviation worldwide.
