Lockheed Martin has announced the Sikorsky HH-60W Combat Rescue Helicopter (CRH) program achieved a Milestone C decision from the U.S. Air Force, which moves the program into low rate initial production.

The Combat Rescue Helicopter will perform critical combat search and rescue and personnel recovery operations for all U.S. military services.

The four instrumented test aircraft at the Sikorsky Development Flight Center in West Palm Beach, Florida, demonstrated their production readiness during rigorous U.S. Air Force (USAF) performance and flight load survey testing.

The joint Sikorsky and USAF flight test team has executed over 150 hours of envelope expansion flights, which provided USAF the data necessary to execute a Milestone C decision.

This decision allows Sikorsky to begin production of the aircraft, which is based on the venerable Black Hawk helicopter. “This affirmative Milestone C decision validates the modifications to Sikorsky’s most successful Black Hawk helicopter, making it capable of saving downed airmen anytime, anywhere around the world,” said Greg Hames, Sikorsky program director. “This establishes the Combat Rescue Helicopter as a production program.
