Sikorsky takes delivery of the third fuselage for the CH-53K King Stallion helicopter program
 
Spirit AeroSystems has successfully delivered to Sikorsky the third fuselage section for the CH-53K ‘King Stallion’ heavy lift helicopter program’s System Demonstration and Test Article (SDTA) contract. Consisting of an integrated cockpit and cabin structure with a separately attached tail section, the composite-skinned fuselage will enable prime contractor Sikorsky to begin assembling the third of four SDTA aircraft to further solidify the final production configuration of the CH-53K aircraft for the U.S. Marine Corps.

“Spirit AeroSystems is pleased to be a major supplier to a new generation, heavy-lift helicopter capability for the Marine Corps,” said Phil Anderson, Spirit senior vice president of Defense Programs. “The strong, lightweight composite structures we are providing to Sikorsky will in turn give the Marine Corps a much needed increase in payload capability.”


Sikorsky came under contract to the U.S. Navy in 2013 to assemble and deliver the four SDTA aircraft by 2017 in support of the Marine Corps operational evaluation of the CH-53K platform. Spirit is on contract to deliver to Sikorsky the final SDTA fuselage unit later this year.

The U.S. Marine Corps will employ the four SDTA aircraft to verify the helicopter’s design capability to carry 27,000 pounds over 110 nautical miles under “high hot” ambient conditions, tripling the external load carrying capacity of the current CH-53E Super Stallion helicopter.

The CH-53K is a general redesign with new engines and cockpit layout. The CH-53K will use General Electric T408 (GE38-1B) engines rated at 7,500 shp (5,600 kW) each and will be able to fly 20 knots (37 km/h; 23 mph) faster than its CH-53E predecessor.

It will feature a new digital glass cockpit with fly-by-wire controls, a new elastomeric hub system, and composite rotor blades to improve "hot and high" performance. The split torque gearbox assembly weighs around 12,500 lb (5,670 kg); by itself heavier than a Blackhawk. The CH-53K will also include an improved external cargo handling system, survivability enhancements, and improvements to extend service life. The cabin will be 30 ft (9.14 m) long by 9 ft (2.74 m) wide by 6.5 ft (1.98 m) tall. Its cabin will be 1 ft (30 cm) wider and 15% larger, but will have new shorter composite sponsons.
