US Approves $800M Bell Helicopter Sale to Iraq
The U.S. approved a potential $800M FMS to Iraq for Bell 412EPX and Bell 407M helicopters to replace aging Russian-built platforms.
The U.S. Department of State has approved a potential $800 million Foreign Military Sale to the Government of Iraq for Bell 412EPX and Bell 407M helicopters. The acquisition is designed to modernize Iraqi Army Aviation and replace aging Russian-built platforms as the country assumes greater responsibility for its internal security.
On August 31, 2026, the Defense Security Cooperation Agency (DSCA) formally notified the U.S. Congress of the proposed package. The agreement designates Fort Worth, Texas-based Bell Textron as the principal contractor and includes associated weapons, electro-optical sensors, and training support.
Modernizing Iraqi Army Aviation
The procurement aims to mitigate supply chain risks associated with Iraq’s current fleet of Russian-built rotorcraft, including Mi-17s. According to the State Department notification, the new helicopters will enhance Iraq’s rotary-wing transport, reconnaissance, and air-to-surface targeting capabilities. The agency stated the sale will support United States foreign policy by helping to improve the security of a strategic partner.
Technical specifications and equipment
The proposed package centers on two distinct rotorcraft platforms. The Bell 412EPX is a twin-engine medium utility helicopter co-developed with Subaru. It features a maximum internal weight of 12,200 pounds, a maximum external weight of 13,000 pounds, a useful load of 5,385 pounds, and a cargo hook capacity of 5,000 pounds. The gross weight for the utility platform is listed at 5,535 kilograms.
Complementing the utility fleet is the Bell 407M, a light single-engine armed reconnaissance helicopter with a gross weight of 2,381 kilograms. The Foreign Military Sale (FMS) package includes the integration of GAU-19 three-barrel machine guns and M260 seven-tube 2.75-inch rocket launchers. Sensor and defensive suites include L-3 Wescam MX-15HDI electro-optical/infrared sensors and AN/AAR-60 Block 2 missile launch detection systems.
Geopolitical Context and Security Transitions
The helicopter acquisition aligns with a critical transition period for Iraqi security forces. The United States-led coalition against the Islamic State is scheduled to conclude its military mission in Iraq by the end of September 2026. This drawdown requires Iraqi forces to independently manage counterterrorism operations, aerial surveillance, and infrastructure protection.
Concurrently, the Iraqi government has established a September 30, 2026 deadline for Iran-affiliated militias operating within the country to disarm. Iraqi Prime Minister Ali al-Zaidi visited Washington a month prior to the FMS approval to discuss these regional security concerns.
The $800 million figure represents a cost ceiling for the entire package rather than a finalized contract value. The exact quantity of Bell 412EPX and Bell 407M airframes remains unspecified in the August 31 notification. The proposed sale now enters a mandatory 30-day congressional review period before a formal contract can be signed. This deal follows a previous $500 million Iraqi procurement of 41 Bell 505 helicopters, with the defense ministry announcing the receipt of the first 15 units in October 2024.
AirPro News analysis
We view this procurement as a definitive step in Iraq’s long-term strategy to decouple its military logistics from Russian supply chains. The ongoing global sanctions against Russian aerospace manufacturers have made sustaining legacy platforms like the Mi-17 increasingly difficult for operators worldwide. By transitioning to the Bell 412EPX and Bell 407M, Iraq secures a more reliable pipeline for parts and maintenance support. However, integrating two new Western rotorcraft types simultaneously will place substantial demands on Iraqi Army Aviation training and maintenance pipelines, right as the operational tempo is expected to increase following the departure of coalition forces.

MH-139 Grey Wolf Achieves IOC for US Nuclear Security
The USAF MH-139 Grey Wolf reached Initial Operational Capability on Aug. 10, 2026, replacing the UH-1N Huey in ICBM security.
The United States Air Force’s MH-139 Grey Wolf helicopters officially achieved Initial Operational Capability (IOC) on August 10, 2026, marking the beginning of the end for the Vietnam-era UH-1N Huey fleet in nuclear security operations.
Announced by the Air Force Global Strike Command (AFGSC) on August 31, 2026, the milestone clears the Boeing-Leonardo platform to actively defend the nation’s intercontinental ballistic missile (ICBM) fields. The Grey Wolf will provide security and transport across the 20th Air Force’s 33,600-square-mile area of responsibility, protecting both the legacy LGM-30G Minuteman III and the upcoming LGM-35A Sentinel systems.
Operational transition and capabilities
The MH-139 brings significant performance upgrades over the UH-1N. According to data from AFGSC and The Aviationist, the Grey Wolf offers a 50 percent increase in speed and doubles the troop-carrying capacity of its predecessor. The platform features a 30 percent larger cabin and a 5,000-pound increase in maximum gross weight.
These enhancements allow security forces to respond more rapidly and with heavier equipment across the vast missile fields of the American West. Beyond nuclear security, the aircraft will be utilized for search and rescue, disaster response, and medical evacuations.
“It has been a distinct privilege to watch the iconic Huey faithfully support our global operations throughout my entire career. However, this transition represents a critical leap forward. The advanced capabilities of the MH-139A Grey Wolf will directly empower our airborne forces with the enhanced speed, range, and survivability required to decisively defend and secure the Minuteman III weapons system,” said Col. Bryant Bevan, Commander of the 582nd Helicopter Group.
Development path and convoy milestones
The United States Air Force (USAF) awarded the initial $2.4 billion contract to the Boeing-Leonardo team in September 2018. The MH-139 is a militarized variant of the commercial Leonardo AW139. The airframes are manufactured by Leonardo S.p.A. in Philadelphia, Pennsylvania, before undergoing military-specific modifications by The Boeing Company.
The road to IOC included a key operational test earlier in the year. On January 8, 2026, the 40th Helicopter Squadron conducted the first operational Minuteman III ICBM convoy with the MH-139 at Malmstrom Air Force Base in Montana. During this mission, two Grey Wolf helicopters escorted a column of missile maintenance and armored security vehicles over 100 miles during a six-hour movement without requiring refueling.
“For more than half a century, the UH-1N Huey has been a key element of our Inter-Continental Ballistic Missile (ICBM) security, and we owe a debt of gratitude to the crews who flew and maintained it over all these years. Securing these missiles demands our best efforts and the MH-139 will significantly improve our capabilities,” stated Gen. S.L. Davis, Commander of Air Force Global Strike Command.
AirPro News analysis
We view the IOC declaration of the MH-139 Grey Wolf as a critical modernization step for the airborne component of the US nuclear triad’s ground segment. The UH-1N fleet has operated well beyond its originally intended service life, creating capability gaps in speed and payload that modern security environments exploit. By leveraging an existing commercial platform in the AW139, the USAF avoided the extended development timelines typical of clean-sheet military rotorcraft, though the integration of military-specific systems still required a multi-year effort following the 2018 contract award. The successful deployment of the Grey Wolf is essential to maintaining credible security during the complex transition from the Minuteman III to the Sentinel ICBM architecture over the next decade.
