The award raises the number of helicopters under contract to 42. Boeing has delivered 27 aircraft to date.
“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,” said Kathleen Jolivette, vice president and general manager of Vertical Lift Programs at Boeing Defense, Space & Security. “Adding these aircraft to the production queue brings additional momentum to ongoing fielding and modernization efforts.”
Boeing said the first full-rate production award enables deployment to scale for operational missions. It adds aircraft to the production queue as the Air Force continues fielding and modernization.
Security and transport roles
The Air Force acquired the MH-139 to monitor intercontinental ballistic missiles and transport security forces and government officials. Boeing integrates military capabilities into Leonardo’s AW139 platform and serves as prime contractor for the U.S.-produced helicopter.
The design also supports patrol, search and rescue, firefighting, and troop and cargo transport. Its modular cabin offers configurations with seating for up to 11 people.
Performance and sustainment
Boeing lists a maximum range of 410 nautical miles and maximum cruising speed of 146 knots. Maximum speed is 167 knots, while the service ceiling is 20,000 feet and maximum takeoff weight is 15,432 pounds.
The helicopter incorporates crashworthy fuel tanks and seats, bird-strike protection and redundant systems. Boeing also identifies encrypted avionics and radio integration among its military and homeland security features.
Training draws on existing AW139 operational flight trainers. Boeing says maintenance can be performed at the operational level, with parts and support available through commercial and defense supply networks.
