Sikorsky to build 6 more CH-53K heavy-lift helicopters for the US Navy

Sikorsky, a Lockheed Martin company will build six additional productions CH-53K King Stallion helicopters under a new contract for the U.S. Navy, Lockheed Martin announced.

The aircraft will further support the U.S. Marine Corps in its mission to conduct expeditionary heavy-lift assault transport of armored vehicles, equipment and personnel to support distributed operations deep inland from a sea-based center of operations.

The six helicopters are part of 200 aircraft Program of Record for the U.S. Marine Corps, and their addition makes a total of 24 CH-53K production aircraft now under contract. Under the terms of this most recent contract – known as Low Rate Initial Production (LRIP) Lot 4 – Sikorsky will begin deliveries of the six aircraft in January 2024.

The CH-53K program has five aircraft on the line at Sikorsky facilities in Connecticut and over two dozen in various stages of production. The program will deliver the first low rate initial production aircraft in September 2021.

Sikorsky and its suppliers have made significant investments in facilities, machinery, tooling, and workforce training to ramp up production required for the CH-53K program. For example, for the first time, newly installed 10-ton cranes lifted a 12,000 lb. gearbox into a CH-53K production aircraft.
