The Sikorsky CH-53E Super Stallion is a heavy-lift helicopter operated by the United States military. As the Sikorsky S-80, it was developed from the CH-53 Sea Stallion, mainly by adding a third engine, adding a seventh blade to the main rotor, and canting the tail rotor 20°. It was built by Sikorsky Aircraft for the United States Marine Corps. The less common MH-53E Sea Dragon fills the United States Navy's need for long-range minesweeping or airborne mine countermeasures missions, and performs heavy-lift duties for the Navy. The Sikorsky CH-53K King Stallion, which has new engines, new composite rotor blades, and a wider aircraft cabin, is set to replace the CH-53E.
The CH-53 was the product of the U.S. Marines' "Heavy Helicopter Experimental" (HH(X)) competition began in 1962. Sikorsky's S-65 was selected over Boeing Vertol's modified CH-47 Chinook version. The prototype YCH-53A first flew on 14 October 1964. The helicopter was designated "CH-53A Sea Stallion" and delivery of production helicopters began in 1966. The first CH-53As were powered by two General Electric T64-GE-6 turboshaft engines with 2,850 shp (2,125 kW) and had a maximum gross weight of 46,000 lb (20,865 kg), including 20,000 lb (9,072 kg) in the payload.
Variants of the original CH-53A Sea Stallion include the RH-53A/D, HH-53B/C, CH-53D, CH-53G, and MH-53H/J/M. The RH-53A and RH-53D were used by the US Navy for minesweeping. The CH-53D included a more powerful version of the General Electric T64 engine, used in all H-53 variants, and external fuel tanks. The CH-53G was a version of the CH-53D produced in West Germany for the German Army.
The U.S. Air Force's HH-53B/C "Super Jolly Green Giant" was for special operations and combat rescue, and was first deployed during the Vietnam War. The Air Force's MH-53H/J/M Pave Low helicopters were the last of the twin-engined H-53s and were equipped with extensive avionics upgrades for all-weather operation.
Although dimensionally similar, the three-engined CH-53E Super Stallion is a much more powerful aircraft than the original Sikorsky S-65 twin-engined CH-53A Sea Stallion. The CH-53E also added a larger main rotor system with a seventh blade.
The CH-53E was designed for transporting up to 55 troops with the installation of seats along the cabin center line or 30,000 lb (13,610 kg) of cargo, and can carry externally slung loads up to 36,000 lb (16,330 kg). The CH-53E has incorporated the same crash-attenuating seats as the MV-22B to increase the survivability of passengers, but reduced its troop transport capacity to 30. The Super Stallion has a cruise speed of 173 mph (278 km/h) and a range of 621 miles (1,000 km). The helicopter is fitted with a forward-extendable in-flight refueling probe.
