Triumph Group Inc.’s Actuation Products & Services business has been awarded a contract from Sikorsky, a Lockheed Martin company, for the CH-53K King Stallion rotorcraft. Triumph will provide the main rotor blade fold actuation and dampening systems for lots 7 and 8, including spares. This work will be performed at Triumph's facility in Seattle, Washington.

"Delivering critical flight components for the CH-53K is an important strategic step in our longtime partnership with Sikorsky," said Mike Boland, president, Triumph Actuation Products & Services. "This multiple lot contract continues Triumph's dedication to providing our military customers with critical high performing technical solutions and engineered products."

In August 2023, the U.S. Navy awarded Sikorsky a $2.7 billion contract to build and deliver 35 additional CH-53K helicopters – the largest procurement to date for this multi-mission aircraft.

The agreement included 12 U.S. Marine Corps Lot 7 aircraft, 15 U.S. Marine Corps Lot 8 aircraft, and eight aircraft for Israel.

Sikorsky will begin delivering these aircraft in 2026.
