Sikorsky and the U.S. Army have established a flexible production agreement for the UH-60M Black Hawk helicopter, beginning with an initial order of 16 aircraft to bridge the gap between current and future procurement cycles.

Announced by Lockheed Martin on September 30, 2026, the arrangement is designed to maintain an active manufacturing line at the company’s Stratford, Connecticut, facility as the Army’s 10th multiyear contract concludes at the end of 2027. The structure allows the U.S. Department of Defense to add aircraft as domestic requirements emerge and Foreign Military Sales (FMS) cases mature, avoiding the costs and delays associated with a cold production restart.

Structuring the undefinitized contract action

The foundation of the new arrangement was laid on September 17, 2026, when the U.S. Army awarded Sikorsky a $234.46 million undefinitized contract action (UCA). According to reporting by Breaking Defense, this modification brings the cumulative value of the underlying contract to $356.25 million. A UCA allows the manufacturer to begin acquiring long-lead components and start subassembly work before the final price is formally negotiated.

By initiating work now, Sikorsky can ensure that deliveries of the 16 newly ordered UH-60M helicopters will begin in 2028. The estimated completion date for this initial batch of aircraft is June 30, 2028. Lockheed Martin expects the total number of aircraft ordered under this novel agreement structure to increase by over 100 units in the coming years.

Funding for the initial 16 aircraft utilizes Congressional appropriations from fiscal years 2025 and 2026. Additionally, the procurement is supported by proceeds from the Army’s Black Hawk Exchange and Sales Transaction (BEST) program. The BEST program allows the military branch to divest older aircraft models to help fund the acquisition of new helicopters without requiring additional taxpayer resources.

Rich Benton, vice president and general manager of Sikorsky, emphasized the utility of the new procurement model in a company press release. Benton noted that the contract structure provides the Army with flexibility as budgets and needs fluctuate year-to-year.

“This agreement turns a partner-nation decision into aircraft on the ramp faster than conventional procurement allows,” Benton stated.

Supply chain and industrial base stability

A primary driver behind the novel production agreement is the preservation of the specialized aerospace industrial base. The Sikorsky supply chain for the Black Hawk program encompasses 230 suppliers distributed across 43 U.S. states. Allowing the production line to go cold at the end of 2027 would have risked the dispersal of this skilled workforce and the degradation of manufacturing capabilities.

Ken Demaree, vice president of Army and Air Forces Systems at Sikorsky, highlighted the difficulty of rebuilding such a workforce once lost. Demaree stated that the agreement ensures aircraft will continue to flow to the Army and allied nations without a pause in production.

The continuity also supports ongoing modernization efforts. Maintaining an active line allows engineers and manufacturers to focus on incorporating new capabilities into the UH-60M platform to evolve alongside the missions flown by military personnel.

Col. Ryan Nesrsta, project manager for the Utility Helicopters Project Office at the U.S. Army, reinforced the strategic necessity of the agreement. Nesrsta stated that the contract ensures the maintenance of a ready, modern, and survivable rotary-wing capability for both domestic forces and international partners.

Half a century of Black Hawk operations

The UH-60 Black Hawk has served as the primary tactical utility transport helicopter for the U.S. Army for decades, executing air assaults, medical evacuations, and resupply missions. The aircraft first flew in 1974 and officially entered production for the Army in 1978. Since that time, Sikorsky has delivered over 5,000 Black Hawk helicopters.

The global footprint of the platform is substantial, with 36 allied nations currently operating the aircraft. Across its operational history, the Black Hawk fleet has accumulated 15 million total flight hours, including 5 million hours logged in combat environments.

The UH-60M represents the current-generation variant of the helicopter. It features significant upgrades over the earlier A and L models, including a fully digital cockpit, wide-chord rotor blades for improved lift, and more powerful engines. The Army awarded Sikorsky its 10th multiyear production contract for the Black Hawk in 2022, a framework that remains active through the end of 2027.

While the U.S. Army continues to develop future vertical lift programs intended to eventually replace the Black Hawk, the UH-60M remains in high demand. The new production agreement is specifically designed to keep the manufacturing line warm and responsive to international orders as they mature, setting the foundation for the platform’s continued production.

The U.S. Army’s decision to utilize an undefinitized contract action for this production agreement highlights a pragmatic approach to industrial base management. By securing long-lead components now, the Army mitigates the risk of a production pause that could have severely degraded Sikorsky’s specialized supply chain of 230 vendors. Reconstituting a dormant aerospace manufacturing line is historically expensive and time-consuming, making this bridge contract a cost-effective stabilization measure.

Furthermore, structuring the agreement to easily accommodate Foreign Military Sales indicates that the Department of Defense views international demand as a critical lever for sustaining domestic manufacturing capabilities. As the Army balances the funding requirements of its future vertical lift initiatives with current operational needs, leveraging allied procurement to keep the UH-60M line active ensures that the U.S. retains a warm production base for tactical utility helicopters well into the next decade.

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.
