Boeing wins first MH-139A Grey Wolf full-rate production contract from US Air Force

The US Air Force has awarded Boeing the first full-rate production award for the MH-139A Grey Wolf helicopter, clearing the way for real-world deployment.

Boeing announced yesterday (1 October) that it had received the contract to supply four more MH-139A Grey Wolf helicopters. The contract follows the US Air Force’s clearance of the programme for full-rate production (FRP) and Initial Operating Capability (IOC) earlier in 2026.

Kathleen Jolivette, vice president and general manager at Boeing’s Vertical Lift Programs, said, “This milestone validates key readiness levels for Grey Wolf and supports the service’s fielding plans to secure vital national assets across the country’s strategic missile fields.”

Jolivette noted that adding the four more helicopters to the production queue brings “additional momentum to ongoing fielding and modernization efforts.”

To date, Boeing has delivered 27 MH-139A Grey Wolf helicopters, of which 20 are low-rate initial production assets. The new order for four helicopters brings the total under contract to 42.

While this is the first full-rate production contract, Boeing has already completed around half of the programme.

The Air Force’s nuclear escort helicopter

In September, AGN reported that the US Air Force has cleared the Grey Wolf helicopter for nuclear security missions. That development came after the US Air Force deployed the Grey Wolf on its first nuclear missile convoy duty in January.

During that mission, two MH-139A helicopters, assigned to the 40th Helicopter Squadron, escorted an operational Minuteman III intercontinental ballistic missile (ICBM) convoy.

The Air Force describes its roles as providing rapid vertical airlift to protect the nation’s land-based nuclear deterrent and transport government officials and security forces.

Primary missions include emergency security response and convoy escort in support of the Air Force’s ICBM fields. It also provides distinguished visitor (DV)/executive airlift in the National Capital Region, among other missions.

Replacing the Vietnam-era UH-1N Huey

The Grey Wolf is now replacing the iconic UH-1N Huey. It’s around 50% faster and is able to carry around twice the number of troops.

Budget documents describe the Huey as having significant capability gaps in speed, range, endurance, payload capacity, and aircraft self-protection.

The US Air Force had planned to develop a different platform under the former Common Vertical Lift Support Program (CVLSP). After that programme was canceled, the USAF awarded Boeing a $2.4 billion contract to replace the Huey with the Grey Wolf.

That contract was awarded in September 2018 and initially covered 84 helicopters. The first aircraft was delivered to Eglin Air Force Base in December 2019 to begin development testing.

The Grey Wolf is based on the commercial Leonardo AW139 helicopter and comes with modifications for US use.

According to Fiscal 2027 budget documents, the Air Force is requesting another four MH-139As next year. Budget documents show the programme of record is for 56 aircraft; this has been raised from a temporary cut to 42.

The current plan to procure 56 Grey Wolves includes eight Aircrew Training Devices (ATDs). The original plan was to procure 80-84 Grey Wolves.
