Boeing Kicks Off MH-139A Grey Wolf Production

Boeing will start producing first 13 MH-139A Grey Wolf helicopters, following the award of a $285 million U.S. Air Force contract for aircraft, sustainment and support services.

“Advancing the program from testing and evaluation to production is a major step toward entering the MH-139 into service and providing the U.S. Air Force with additional missile security for decades,” said Azeem Khan, Boeing’s MH-139 program director.

“We are working diligently to begin deliveries next year,” Khan said.

The MH-139A Grey Wolf is a dual-piloted helicopter powered by two FADEC-controlled Pratt & Whitney Canada PT6 turboshaft engines. It has a cruising speed of 135kt and a maximum speed of 167kt. It can reach a minimum range of 225 nautical miles without the need for refueling. The maximum endurance of the rotorcraft is three hours.

The MH-139A team consists of Boeing, as the prime contractor, and Leonardo as an original equipment manufacturer.
