BAE Systems said it has secured $114 million in contracts to deliver missile warning technology to U.S. allies through the U.S. Army’s Foreign Military Sales (FMS) program, a move aimed at improving how partner countries protect their helicopter fleets from ground-fired threats. The contract centers on the AN/AAR-57 Common Missile Warning System (CMWS), a sensor suite designed to detect incoming missiles and give aircrews enough time to deploy countermeasures. For allied air forces operating aging rotary-wing platforms in contested airspace, the timing of this procurement matters as much as the technology itself, as they seek to keep legacy aircraft viable against increasingly sophisticated shoulder-fired missiles and other infrared-guided threats.
According to a BAE Systems announcement, the $114 million in orders will fund production of new CMWS units, spares, and support for multiple allied customers, with deliveries expected to stretch over several years. While the company has not publicly disclosed the full list of recipient nations, BAE Systems said the AN/AAR-57 Common Missile Warning System (CMWS) is used on platforms including the AH-64 Apache, CH-47 Chinook, and UH-60 Black Hawk. For BAE Systems, the contract reinforces its position as a key supplier of aircraft survivability equipment, while for the U.S. Army it underscores FMS as a tool for strengthening coalition air power without committing additional American aircraft to frontline roles.
What the $114 Million Contract Covers
The deal channels funding through the U.S. Army’s FMS pipeline, meaning allied governments are purchasing the systems with American oversight and logistical support rather than buying directly from BAE Systems. This distinction is more than bureaucratic. FMS cases typically include U.S. government oversight and can emphasize interoperability and end-use monitoring compared with some direct commercial sales arrangements. For nations fielding U.S.-built helicopters, the arrangement helps ensure that the warning systems integrate cleanly with existing avionics, power supplies, and countermeasure dispensers without costly custom engineering or lengthy certification campaigns that can sideline aircraft for months.
The AN/AAR-57 CMWS at the heart of this contract uses an array of ultraviolet sensors to detect the exhaust plume of an approaching missile, then alerts the crew and, depending on configuration, can automatically trigger chaff or flare dispensers. The system is already fielded across a wide range of U.S. military aircraft, which gives allied buyers a proven track record rather than an untested prototype. That maturity is a selling point, though it also raises a fair question: whether a sensor architecture designed years ago can keep pace with newer, more agile threats like man-portable air defense systems with improved infrared seekers and counter-countermeasure algorithms. Still, for many operators, the balance of risk favors a robust, widely used system over waiting for a next-generation solution that may be years from operational readiness.
Platforms That Will Carry the System
BAE Systems identified the AH-64 Apache, CH-47 Chinook, and UH-60 Black Hawk as key examples for CMWS integration. Each of these helicopters fills a different tactical role, from the Apache’s precision attack missions to the Chinook’s heavy-lift transport duties and the Black Hawk’s utility and assault operations. Equipping all three with the same warning system creates a common defensive baseline across an allied fleet, simplifying maintenance, training, and spare-parts logistics. A crew chief trained on CMWS aboard a Black Hawk can transfer that knowledge to a Chinook unit without starting from scratch, reducing the training burden and accelerating deployment timelines.
This standardization also has a strategic dimension. When multiple allied nations operate the same sensor on the same airframes, joint operations become far smoother. Pilots flying in multinational formations share a common threat-detection language, reducing the risk of confusion during high-stress engagements. That kind of interoperability is difficult to achieve when each country sources its own missile warning hardware from different vendors with different interfaces and alerting philosophies. By aligning with the U.S. Army’s chosen system, allied air forces effectively plug into an ecosystem of tactics, techniques, and procedures that have been refined over years of combat operations, from crew drills to maintenance best practices.
Why Allies Are Investing Now
Several factors are likely driving allied demand for missile warning upgrades. Conflicts in recent years have demonstrated that even low-cost shoulder-fired missiles can destroy expensive military helicopters. A single infrared-guided missile costing a few thousand dollars can bring down an aircraft worth tens of millions, along with its crew and passengers. For nations watching these engagements unfold, the calculus is straightforward: investing in warning systems is far cheaper than replacing aircraft and training new pilots. CMWS does not guarantee survival, but it dramatically shortens the window between missile launch and crew response, which can mean the difference between a successful evasive maneuver and a catastrophic hit that leaves no time for flares or hard turns.
There is also a procurement timing element at play. Many allied nations acquired their helicopter fleets years or even decades ago, and the original defensive suites may no longer match the modern threat environment. Upgrading to the AN/AAR-57 through the U.S. Army’s FMS channel offers a relatively fast path to fielding modern sensors without the delays of a full competitive procurement. For smaller air forces with limited acquisition staffs, the FMS process handles much of the contracting and certification burden, freeing up resources for training and integration work. Separately, companies often use distribution services such as PR Newswire’s media services to publicly share contract announcements and program updates.
Limits of a Proven but Aging Design
It is worth questioning whether CMWS, for all its battlefield pedigree, represents the best available technology or simply the most accessible. The AN/AAR-57 has been in service for over two decades, and while BAE Systems has incrementally upgraded its software and sensor performance, the fundamental architecture predates the current generation of adversary missile seekers. Some newer threats may incorporate more advanced seekers and counter-countermeasure techniques, which can complicate detection and defeat. Some competing systems from European and Israeli defense firms incorporate multi-spectral detection and tighter integration with directed infrared countermeasures, potentially offering higher survivability in dense threat environments where multiple missiles may be fired in quick succession.
That said, CMWS benefits from a massive installed base and a deep logistics tail. Spare parts are widely available, software updates flow regularly through U.S. government channels, and the system’s performance data draws on real combat deployments rather than just test-range simulations. For many allied nations, the practical reliability of a well-supported program outweighs the theoretical advantages of a newer but less proven alternative. Ongoing sustainment, including configuration management and access-controlled documentation, can give operators confidence that issues are addressed quickly. The choice is not always about peak performance on paper; it is about what works consistently in the field with the maintenance capacity and budgets a given country actually has.
Strategic Implications for Allied Air Power
The broader significance of this contract extends beyond hardware. When the United States sells missile warning systems to allies through FMS, it creates long-term dependencies that bind those nations more closely to American defense supply chains. Future software updates, sensor refreshes, and spare parts will flow through U.S. channels, giving Washington ongoing influence over allied readiness. That is not necessarily a negative outcome for the buyers, who gain access to U.S. testing, threat intelligence, and upgrade roadmaps, but it is a structural reality that shapes defense relationships for years after the initial sale. In effect, each CMWS installation is also a political linkage, reinforcing alignment with U.S. standards and export controls.
For the allied forces receiving CMWS, the immediate payoff is clear: helicopters that can detect and respond to missile threats faster than they could before. In practical terms, that means Apaches conducting close air support, Chinooks hauling troops and supplies, and Black Hawks flying medevac or special operations missions with an added layer of survivability in hostile airspace. Over time, as more nations adopt the same warning architecture, coalition planners gain greater flexibility to mix and match units from different countries in shared operations, confident that their aircraft will respond in broadly similar ways to the same threats. The $114 million contract, then, is not just a transaction for sensors and wiring harnesses; it is part of a wider effort to knit allied air fleets into a more coherent, resilient whole in the face of evolving missile dangers.
