Boeing has delivered four MH-139A Grey Wolf test aircraft to the U.S. Air Force as the service prepares to replace its aging fleet of UH-1N helicopters.
The Grey Wolf is a multi-mission aircraft – based on the proven commercial AW139 helicopter – designed to protect intercontinental ballistic missiles and transport U.S. government officials and security forces. Boeing was awarded a US$2.4 billion (£2 billion) contract in September 2018 for 80 helicopters, training systems and associated support equipment.
The delivery milestone follows receipt of the Federal Aviation Administration-issued supplemental type certificate, required to commence deliveries. With aircraft in hand, the Air Force will now proceed with military utility testing as the programme progresses toward Milestone C.
