The first MH-139 for the Air Force—which replaces the UH-1N Huey in the roles of nuclear missile field support, VIP transport, and some other missions—is in production at Agusta-Westland facilities north of St. Louis, Mo., and if there are no hiccups, it will fly by the end of the year, Boeing officials reported. The Agusta-Westland facility, part of Boeing’s major subcontractor, Leonardo, will assemble the fuselage, put on the rotors, and essentially build a civilian version of the aircraft, Rick Lemaster, company director of vertical lift marketing, told reporters in a briefing at Boeing’s Philadelphia, Pa., helicopter factory on May 16. It is then handed over to Boeing, which militarizes it for the Air Force’s unique missions. Boeing will convert the vanilla aircraft into an MH-139 by changing the baggage door compartment to “allow some special equipment to be installed” that the Air Force declines to identify. Defensive aids, such as flare dispensers and missile warning systems will be added, as will the machine gun mount and a “crashworthy, self-sealing fuel tank,” Lemaster explained.  Additionally, ballistic protection will be added to the floor and cockpit. Once complete, the aircraft will receive USAF certification and fly off to their duty station. Lemaster said the Air Force will likely “turn on production in the next year or two, and once that happens the company anticipates to deliver about 10 aircraft per year into the early 2030s. The numbers may vary, as USAF’s contract allows for more or less aircraft each year. The MH-139 is a $2.38 billion firm, fixed-price contract program, of which $375 million gets the ball rolling with engineering and manufacturing development. Although the Air Force quoted a figure of $1.7 billion in savings when it announced Boeing had won the UH-1N replacement contest last fall, Boeing’s number is more conservative, Lemaster said. “We said we could save $1 billion, in terms of overall life cycle costs, or compared to competitors. That was our calculation, between support cost and acquisition.” The big discriminator between Boeing and its chief rival, the Lockheed Martin/Sikorsky Blackhawk, was the fact that the Air Force didn’t need a larger, combat-capable aircraft, he said. “This aircraft is relatively easy to maintain compared to competitors,” Lemaster said. The MH-139 is “not as big and heavy as a Blackhawk,” which he called “a great capability, great in combat, but that’s not what the Air Force requirement was.” Boeing’s approach was to offer an aircraft that is “right-sized for the mission,” Lemaster asserted. The first two aircraft are to be delivered in late 2020. They will then enter a test program, and if all goes well, operational testing will be in 2022, followed by full-rate production in 2023. The Air Force will buy at least 84 MH-139s. Armed versions with an M240 machine gun externally mounted on the starboard side will be fielded by three Air Force Global Strike Command bases, each with 11 aircraft to rapidly respond to threats at missile fields and provide other support for the ICBM mission. Some 30 aircraft will be based at JB Andrews, Md., for VIP transport. Four aircraft each will support VIP and aeromedical evacuation missions at Yokota AB, Japan, and the Air Force survival, evasion, resistance, and escape school at Fairchild AFB, Wash. The MH-139 “schoolhouse” at Kirtland AFB, N.M., will get the remainder, minus the two initial aircraft, which will stay at Eglin AFB, Fla., for ongoing test of modifications and software.
Lemaster said the AW-139, on which the MH-139 is based, is in service with 250 customers in 70 nations, and the fleet has accumulated more than two million flight hours, “So it’s a very mature product,” allowing Boeing to quote fixed-price support costs. The Air Force plans to fly the aircraft 480 hours per year, each. The highest-time version of the aircraft has just reached 12,000 flight hours, so it will be a long time before the Air Force will need to think about the MH-139’s replacement, Lemaster said.
“There is no airframe life limit, so there’s no requirement to take it back to a depot and do modifications,” he noted. Having succeeded in running over an hour with no transmission oil—a “run dry” test, Lemaster said, “It’s just a very survivable aircraft.” Additionally, the helicopter has been certified for one pilot under instrument flight rules, meaning the service could optionally relax its two-pilot requirement down the road, he said. For ease of maintainability, the engine and transmission are above the cabin, and built-in foot stands allow preflight inspections without putting a hardstand next to the aircraft, he said. There’s “one contiguous open space” in the cabin, offering flexibility of use. Although the engines don’t have infrared suppressors, the exhaust heat is fairly low, without intense hotspots that would make a good infrared target. Lemaster said he thinks the first batch of aircraft will be a run of eight, but “there’s a lot of flexibility in the way the contract is structured, so they can add or subtract the quantity. We’ve given them firm pricing for all of those iterations, and they’ll buy what they want.”

PRESS RELEASE – 25 September 2018

U.S. Air Force selects the MH-139 based on the world-class Leonardo AW139 helicopter for Intercontinental Ballistic Missile protection and government and security forces transport missions.

  • The MH-139 programme, offered by Boeing as prime contractor, is valued at $2.4 billion
    for up to 84 helicopters training devices and associated support equipment with initial
    readiness by 2021
  • Profumo: “This result is testament to Leonardo’s ability to meet the most stringent
    requirements of major customers, and a recognition of the Company as a strong, reliable
    partner and long established contributor to the US industry”
  • Philadelphia-built aircraft will be operated by the U.S. Air Force to replace their UH-1N
    Huey fleet leveraging modern technology, high performance and with a savings of $1
    billion in acquisition and lifecycle costs over the life of the fleet
  • Over 900 AW139s are already in service among 270 governments, militaries and
    companies across the world, with 260 assembled and delivered from Philadelphia

Rome, 25 September 2018 – The United States Air Force (USAF) selected the MH-139, based on the Leonardo AW139 and offered by Boeing as prime contractor, to replace its fleet of UH-1N “Huey” helicopters. The programme awarded today is valued at $2.4 billion for up to 84 helicopters, training devices and associated support equipment. With initial operational capability expected by 2021, the aircraft will take over the role of protecting the nation’s intercontinental ballistic missile (ICBM) bases and the transportation of U.S. government and security forces. Alessandro Profumo, Chief Executive Officer, Leonardo said “We are extremely proud of this outstanding result. Major customers continue to rely on Leonardo to meet the most stringent requirements like the critical mission of protecting missile bases and transporting government personnel and special forces. This selection is also testament to Leonardo as a strong, reliable partner and long established contributor to the US industry.” The MH-139 leverages the market-leading Leonardo AW139 baseline, a modern, nondevelopmental, multi-mission helicopter that is in service worldwide and has already demonstrated its capabilities in protecting critical infrastructures and transporting military and government representatives in various nations. Gian Piero Cutillo, MD Leonardo Helicopters, said “Today’s announcement is a strong recognition of the world-class quality and competitiveness of our product to meet the most demanding needs of leading customers.” The MH-139 is the right-sized aircraft for the mission, exceeds the Air Force’s speed, payload, range, armament and survivability requirements for protecting ICBM bases, and is perfect for VIP  transport. The type features modern design and the best level of affordability with a savings of $1 billion in acquisition and lifecycle costs over the life of the fleet. The AW139 is assembled at the Leonardo northeast Philadelphia plant, with additional components to be integrated into the military MH-139 at the Boeing Philadelphia facility in Ridley Township, Pa. William Hunt, CEO, AgustaWestland Philadelphia Corporation, said “We are happy that the U.S. Air Force has selected our team to deliver a new fleet of Philadelphia-built MH-139s. Our Air Force deserves the best tools; this is the right helicopter for their mission. The more than $125M investment made by Leonardo in the Philadelphia facility demonstrates that we are fully prepared to execute in support of this contract. We look forward to working with Boeing on this programme and we’re committed to deliver according to expectations of the prime contractor, the US Government and taxpayers.”
