The U.S. Air Force has awarded The Boeing Company an $85 million contract for four MH-139A Grey Wolf helicopters, marking the program’s transition into full-rate production for the nuclear security mission.

Announced by Boeing in a press release on October 1, 2026, the September 25, 2026 contract award accelerates the replacement of the Vietnam-era UH-1N Huey fleet currently guarding intercontinental ballistic missile (ICBM) fields across the United States.

Transitioning to full-rate production

The full-rate production contract allows the U.S. Air Force (USAF) to scale the deployment of the MH-139A across its strategic missile fields. Prior to this award, Boeing delivered 27 aircraft, which included 20 low-rate initial production assets and several test aircraft. The new order brings the total number of Grey Wolf helicopters under contract to 42.

Kathleen Jolivette, Vice President and General Manager of Vertical Lift Programs at Boeing Defense, Space & Security, stated that the milestone validates key readiness levels for the aircraft. Adding the helicopters to the production queue, she noted, brings momentum to ongoing fielding and modernization efforts.

The production milestone follows a critical operational achievement for the platform. On August 31, 2026, Air Force Global Strike Command (AFGSC) announced that the MH-139A achieved Initial Operational Capability (IOC) on August 10, 2026. The IOC designation officially cleared the aircraft for real-world nuclear security missions.

Modernizing nuclear security capabilities

The MH-139A program was established to replace the UH-1N Huey, a platform that has guarded U.S. ICBM fields for more than 50 years. The Grey Wolf provides substantial performance upgrades over the legacy fleet, offering a 50 percent speed increase and the ability to carry twice the payload. These enhancements are designed to improve the rapid response capabilities of security forces patrolling 33,600 square miles of ICBM fields.

The helicopters will be deployed to secure assets at Malmstrom Air Force Base in Montana, F.E. Warren Air Force Base in Wyoming, and Minot Air Force Base in North Dakota.

Based on the commercial Leonardo AW139, the MH-139A is manufactured through a partnership between Leonardo Helicopters and Boeing. Leonardo builds the base helicopter at its facility in Philadelphia, Pennsylvania, before transferring the airframe to Boeing for the installation of specialized military equipment.

Procurement targets for the program have fluctuated since the initial contract award on September 24, 2018. The USAF originally planned to acquire 80 helicopters, later reducing the objective to 42. However, the fiscal year 2026 budget request recently increased the procurement objective to 56 aircraft. Deliveries for the four helicopters in this initial full-rate production batch are expected in 2028 or 2029.

The shift to full-rate production signals stabilization for the MH-139A program following earlier procurement quantity adjustments. Securing this contract alongside recent F-15EX and F/A-XX awards caps a highly successful procurement week for Boeing Defense, Space & Security. We view this momentum as a critical reinforcement of Boeing’s position in U.S. military modernization efforts, providing a stable production outlook for the Philadelphia manufacturing line through the end of the decade.

BAE Systems has secured AIMS certification for its AN/APX-127(V)1 Combined Interrogator Transponder, clearing the modernized Identification Friend or Foe system for operational use on the U.S. Air Force F-16 Fighting Falcon.

Announced in a company press release on September 29, 2026, the certification validates the system’s compliance with current United States and NATO interoperability standards. The approval specifically covers the encrypted Mode 5 protocol required to distinguish allied aircraft from potential threats in contested airspace.

System architecture and production

The AN/APX-127(V)1 Combined Interrogator Transponder (CIT) consolidates interrogator and transponder functions into a single unit designed for highly maneuverable tactical aircraft. BAE Systems engineered the unit with an open-system architecture, allowing for future software upgrades without requiring hardware modifications. The manufacturer maintained the same form factor as its legacy systems, enabling the new CIT to serve as a drop-in replacement for the AN/APX-113(V), AN/APX-125(V), and AN/APX-126(V) systems currently operating on multiple domestic and international platforms.

Seth Guanu, Combat Identification Products program area director at BAE Systems, stated the company is investing in the next generation of Identification Friend or Foe (IFF) technology to support customer missions.

“Our multi-domain systems are designed for high-performance; easily upgradeable; and meet size, weight, and power objectives for existing and emerging platforms. This solution provides added security and real-time information pilots need in a variety of threat environments.”

Manufacturing and development work for the AN/APX-127(V)1 takes place at BAE Systems facilities in Greenlawn, New York, and Austin, Texas. The company expects to begin delivering the first 90-unit production lot in 2026.

The Mode 5 transition and AIMS certification

The AIMS certification is a mandatory interoperability standard for IFF solutions used by the U.S. military and allied forces. The certification is overseen by the U.S. Department of Defense (DoD) AIMS program office, though the BAE Systems press release referred to the certifying body using the historical designation “Department of War.”

A primary driver for the AN/APX-127(V)1 upgrade is the integration of Mode 5 capabilities. Mode 5 is the current encrypted NATO standard, which replaces the older Mode 4 protocol. The updated standard ensures secure identification of friendly aircraft to prevent friendly fire incidents during complex multi-domain operations.

The AIMS Mark XIIB IFF certified system also supports Mode S and includes additional receive channels for the passive acquisition of Mode 5 Level 2 and Automatic Dependent Surveillance-Broadcast In (ADS-B In) data.

Eighty years of IFF development and international expansion

BAE Systems has over 80 years of experience developing IFF technology. Across all military service branches, the company has delivered more than 1,500 interrogators, 6,000 combined interrogator transponder systems, and 16,000 transponders for applications including air defense, weapon systems, air traffic control, and range instrumentation.

On December 15, 2025, Korea Aerospace Industries (KAI) awarded BAE Systems an $11 million contract to integrate the same CIT system onto the KF-21 Boramae tactical aircraft. This parallel integration demonstrates the system’s viability on emerging platforms alongside legacy fighters like the F-16.

The transition to Mode 5 represents a critical modernization hurdle for global Air Forces operating legacy combat aircraft. By designing the AN/APX-127(V)1 as a drop-in replacement for the widely used AN/APX-113(V) series, BAE Systems provides operators with a streamlined path to meet the NATO Mode 5 mandate without requiring extensive hardware modifications or prolonged aircraft downtime.

Securing AIMS certification for the F-16 Fighting Falcon opens a massive potential upgrade market, given the thousands of F-16s still in active service globally. The concurrent integration on the clean-sheet KF-21 Boramae indicates the architecture is flexible enough to bridge the gap between fourth-generation upgrades and next-generation fighter development, positioning BAE Systems to capture both retrofit and forward-fit IFF contracts.

Avio USA broke ground on a 900,000-square-foot solid rocket motor manufacturing facility in Pittsylvania County, Virginia, on September 29, 2026, introducing a new independent supplier to the consolidated U.S. defense industrial base.

The project is supported by major defense contractors Lockheed Martin Corporation and Raytheon. According to a company press release, the facility represents an investment of more than $500 million and is expected to create roughly 1,500 technical jobs in the region, adding critical domestic capacity for tactical missile and munitions programs.

Expanding domestic munitions capacity

Avio USA, a subsidiary of Italy-based aerospace company Avio S.p.A., held the groundbreaking ceremony at the Southern Virginia Multimodal Park in Hurt. The event drew representatives from the state government and the defense industry, highlighting the strategic importance of the new site.

The facility is designed to operate as an independent merchant supplier. This model allows Avio USA to provide solid rocket motors to multiple defense primes rather than operating as a captive supplier to a single manufacturer.

“Avio USA is building more than a manufacturing facility in Virginia. We are building an American company and workforce that can bring Avio’s proven propulsion expertise to the U.S. defense market,” said James Syring, CEO of Avio USA. “Our goal is to be an independent, open-source merchant supplier, able to support multiple customers and programs and provide major defense primes with an additional source for this critical capability.”

Executives from both Lockheed Martin and Raytheon attended the ceremony, underscoring the industry demand for the new plant. Tim Cahill, President of Lockheed Martin Missiles and Fire Control, noted that the facility is a significant step toward a more robust supply chain. Bob Butz, Senior Vice President of Operations, Supply Chain and Quality at Raytheon, stated that the groundbreaking expands national manufacturing capacity for solid rocket motors.

State incentives and construction timeline

The September 29, 2026, groundbreaking follows a site selection process that concluded on December 11, 2025. To secure the project, the Virginia General Assembly and the Major Employment and Investment Project (MEI) Commission approved a special appropriation incentive package of up to $97.7 million on February 23, 2026.

The state incentives were based on Avio USA committing to invest more than $500 million and create over 1,000 jobs, though subsequent company communications project the creation of roughly 1,500 high-quality technical roles.

Virginia Governor Abigail Spanberger praised the development, stating that the investment will advance critical manufacturing capabilities and reinforce the position of the state as a premier destination for aerospace and defense industry growth.

According to financial news reporting, construction of the Hurt facility is expected to be completed in late 2028. The commencement of solid rocket motor production is scheduled for early 2029.

Breaking the solid rocket motor duopoly

The U.S. solid rocket motor market has historically been highly consolidated, leading to supply chain bottlenecks as demand for tactical munitions has increased. The Pentagon and major defense contractors have actively pushed for new entrants to increase production capacity, foster competition, and build resilience into the supply chain.

Avio S.p.A., founded in Rome in 1912, specializes in the design and manufacturing of space launchers, including the Vega C, and tactical missiles. The company employs over 1,500 people across Italy, France, French Guiana, and the United States. To serve the U.S. defense market and handle classified materials, Avio USA operates under a Defense Counterintelligence and Security Agency (DCSA) Special Security Agreement.

AirPro News analysis

The entry of Avio USA into the domestic solid rocket motor market addresses one of the most acute vulnerabilities in the U.S. defense supply chain. For years, the sector has been dominated by just two primary suppliers, creating a fragile ecosystem that struggled to scale up production in response to recent global conflicts and the resulting depletion of U.S. munitions stockpiles. By establishing an independent, open-source merchant facility, Avio USA provides prime contractors like Lockheed Martin and Raytheon with a neutral alternative. We view this development as a direct validation of Department of Defense initiatives aimed at diversifying the industrial base, which will likely ease production bottlenecks for critical tactical missile programs by the end of the decade.
