Who supplies the MH-139A Grey Wolf? Inside the Boeing–Leonardo production model
Published October 2, 2026 / MH-139A Grey Wolf supply chain
The U.S. Air Force has placed its first full-rate production order for the MH-139A Grey Wolf.
The latest award covers four helicopters, taking the total under contract to 42. Boeing has delivered 27 aircraft so far, while the Air Force's current program of record covers 56.
Boeing is the prime contractor, but the MH-139A is based on Leonardo's commercial AW139.
Leonardo manufactures the base helicopter at its facility in northeast Philadelphia before Boeing installs the military-specific equipment at its Ridley Park operation.

Where the first-tier subcontract value flowed
Positive first-tier subcontract obligations beneath Boeing's main award, FY2021–FY2025
Mimir identifies 68 first-tier supplier sites and approximately $416 million in mapped subcontract obligations beneath Boeing's main MH-139A award.
Leonardo's Samarate operation represented the additional approximately 10%.
Together, the two Leonardo operations accounted for approximately $350 million.
The military modification and support network
Selected first-tier supplier positions identified in the Mimir records
The remaining value was distributed across the military modification, mission-equipment and support network. Supplier positions included:
Pinnacle Solutions
Huntsville, Alabama
Aerospace support
Mimir records identify an aerospace-support position beneath Boeing's main MH-139A award.
Teledyne FLIR
Wilsonville, Oregon
Electro-optical/infrared system
Teledyne FLIR supplies the existing Star SAFIRE 380HDc EO/IR system fitted to the aircraft.
BAE Systems
Greenlawn, New York and Austin, Texas
Mapped systems and avionics activity
BAE Systems operations in Greenlawn and Austin appear in first-tier records associated with the program.
Northrop Grumman
Northridge, California
Mapped systems activity
The Northridge operation appears as a specialist first-tier systems position beneath Boeing.
Integris Composites
Hebron, Ohio
Ballistic armor
Integris produces the ballistic armor incorporated into the MH-139A Grey Wolf.
Teledyne FLIR supplies the aircraft's existing Star SAFIRE 380HDc electro-optical/infrared system, although the Air Force is currently evaluating an upgrade to the EO/IR capability. Integris produces the Grey Wolf's ballistic armor.
A commercial-derivative production model
Most of the first-tier value beneath Boeing flowed to Leonardo for the underlying AW139 platform, with the remaining network supporting military-specific systems, modification and support activity.
The subcontract data therefore reflects the MH-139A's commercial-derivative production model.
Full-rate production will scale both parts of that model: Leonardo's AW139 manufacturing base and the suppliers supporting Boeing's military configuration of the aircraft.
