Powered ground tests of the Sikorsky CH-53K, the U.S. Marine Corps’ future heavy-lift helicopter, are now well under way at the company’s West Palm Beach, Florida facility in the run-up to first flight later this year. The first ground-test vehicle (GTV1) started systems testing in late April, about a week before the first flying article was rolled out on May 5. Operational service of the mostly composite helicopter, which has been dubbed the “King Stallion,” is expected in 2019.

Sikorsky Aircraft rolled out the CH-53K, the U.S. Marine Corps’ future heavy lift helicopter, on May 5 at the company’s West Palm Beach, Fla. facility. According to Sikorsky, the mostly composite helicopter–dubbed the “King Stallion”–will fly by year-end, with operational service expected in 2019.
In the military segment, while clearly concerned with continuing budget constraints, Sikorsky expects to achieve two milestones this year with the first flights of the CH-53K, the latest version of its heavy-lift military transport, and the S-97 Raider.
The first four flying versions of the U.S. Marine Corps’ next generation CH-53K helicopter were advancing through assembly at Sikorsky Aircraft’s West Palm Beach, Florida, facility earlier this year. “We’re well beyond the paper side of the aircraft. We’re building this thing,” Marine Col. Robert Pridgen, H-53 program manager, told reporters at the Navy League conference in April.
