Lockheed Martin’s Sikorsky Aircraft Corp. has landed a $10.8 billion U.S. Navy contract to produce up to 99 CH-53K King Stallion helicopters over the next five years, cementing the program’s largest order to date. The heavy-lift aircraft, built to replace the aging CH-53E fleet, is billed as the most powerful helicopter ever fielded by the United States.

The award, announced Friday, will support Marine Corps operations and potentially international customers, underscoring the King Stallion’s role in shaping the future of battlefield mobility.

A Strategic Win in a Rapidly Shifting Battlespace

Sikorsky’s vice president and general manager Rich Benton hailed the contract as a game-changing milestone. “This multi-year deal lets us drive affordability, streamline production, and secure the supply chain,” he said, noting the importance of giving Marines “a strategic edge in a rapidly evolving battlespace.”

Equipped with three robust engines, the CH-53K can haul troops, supplies, or equipment weighing up to 36,000 pounds—enough muscle to transport armored vehicles or critical gear across combat zones.

Details of the Pentagon Deal

The agreement, a firm-fixed-price modification of an earlier contract, was not open to competition, according to the Department of Defense. The modification consolidates five procurement lots—numbers 9 through 13—into a single five-year buy running from 2029 through 2034. Nearly 270 suppliers across 37 states will contribute to the production push.

Sikorsky has already delivered 20 of the aircraft to the Marine Corps and has 63 more in various stages of production from earlier lots.

Program Leaders Applaud the Momentum

Col. Kate Fleeger, who oversees the Navy’s H-53 Heavy Lift Helicopter Program Office, called the award “a huge win for the entire CH-53K team.” She emphasized that combining orders allows Sikorsky to leverage bulk pricing, stabilize production schedules, and ensure “a dependable delivery to the fleet.”

The streamlined procurement also provides predictability in the Marines’ transition from the CH-53E to the CH-53K, a move seen as vital for maintaining U.S. military heavy-lift dominance into the next decade.
