First Prototypes of U.S. Marine Corps CH-53K To Fly Soon

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.
