This aircraft, built in Sikorsky’s digital factory, is the first CH-53K from the Lot 2 LRIP contract awarded by the U.S. Navy in 2019, and the seventh overall delivered to the fleet.

The CH‑53K’s heavy-lift capabilities exceed all other U.S. Department of Defense rotary wing platforms and is the only heavy-lift helicopter that will remain in production through 2032 and beyond.

This CH-53K heavy lift helicopter joins the six in operation at Marine Corps Air Station New River in Jacksonville, North Carolina. The CH-53K is the only sea-based, long range, heavy lift helicopter in production and will immediately provide three times the lift capability of its predecessor.

Technical details about the CH-53 K helicopter

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

It features a new digital glass cockpit with fly-by-wire controls and haptic feedback, HUMS, a new elastomeric hub system, and composite rotor blades to improve "hot and high" performance.
