U.S. Marines flying a CH-53K King Stallion heavy-lift helicopter transported an F-35C Lightning II airframe from the F-35 Integrated Test Force at Patuxent River (Pax ITF) to a Navy unit located at Joint Base McGuire-Dix-Lakehurst, New Jersey, April 24. A Marine aviator from Marine Test and Evaluation Squadron 1 (VMX-1) piloted the most powerful helicopter in the U.S. Department of Defense that carried the inoperable airframe, which was without mission and propulsion systems, outer wings, or additional equipment, to the Prototype, Manufacturing and Test (PMT) Department of the Naval Air Warfare Center Aircraft Division (NAWCAD) Lakehurst for use in future emergency recovery systems testing. Naval Air Warfare Centers are research organizations within Naval Air Systems CoMMAnd.

The Sikorsky CH-53K King Stallion (Sikorsky S-95) is a heavy transport helicopter designed and produced by Sikorsky Aircraft. The King Stallion is an evolution of the long running CH-53 series of helicopters which has been in continuous service since 1966, and features three up-rated 7,500 shp (5,590 kW) engines, new composite rotor blades, and a wider aircraft cabin than its predecessors. The CH-53K will keep approximately the same footprint as the CH-53E. It is the largest and heaviest helicopter in the U.S. Military. The United States Marine Corps plans to receive 200 helicopters at a total cost of $25 billion. Ground Test Vehicle (GTV) testing started in April 2014; flight testing began with the maiden flight on 27 October 2015. In May 2018, the first CH-53K was delivered to the Marine Corps.

The CH-53K King Stallion is a heavy lift helicopter, being a general redesign of the preceding CH-53E, the main improvements being the new engines and cockpit layout. It has over twice the lift capacity and radius of action of the CH-53E, and a wider cargo hold to allow it to carry a Humvee internally. A new composite rotor blade system is also used, featuring Technology similar to that of the UH-60 Black Hawk helicopter. The CH-53K is powered by the General Electric GE38-1B engine, which was selected over the Pratt and Whitney Canada PW150 and a variant of the Rolls-Royce AE 1107C-Liberty used on the V-22 Osprey. Each of the three T408 engines is rated at 7,500 shp (5,600 kW), and gives the CH-53K the ability to fly 20 knots (37 km/h; 23 mph) faster than its CH-53E predecessor.

The CH-53K has 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.[58] Its cabin will be 1 ft (30 cm) wider and 15% larger, but will have new shorter composite sponsons. The CH-53K can carry two 463L master pallets, eliminating the need to break apart pallets between airlifter and helicopter. The CH-53K is to surpass the capability of its predecessor by carrying nearly 30% more than the CH-53E’s external payload of 27,000 lb (12,200 kg) over the same radius of 110 nmi (204 km). The CH-53K’s payload reaches a maximum of 35,000 lb (15,900 kg). The CH-53K’s maximum gross weight will be 88,000 lb (39,900 kg), which is increased over the CH-53E’s 73,500 lb (33,300 kg).
