{loadposition bannertop} {loadposition sidebarpub} The US Army awarded Northrop Grumman a 4,838,487,318 for full-rate CIRCM production. Army Contracting Command at Redstone Arsenal, Alabama, is managing the agreement under contract W58RGZ-26-D-0056. Work locations and funding will be determined as individual orders are placed, meaning that the entire contract ceiling is not obligated at once. CIRCM is a directional infrared countermeasure system. It does not independently detect missile launches, but instead receives threat information from warning sensors installed on the aircraft, including the Common Missile Warning System, Limited Interim Missile Warning System, or Advanced Threat Warner. Once the threat has been located, a pointer and tracker assembly is directed toward the incoming missile, acquires it, and projects modulated laser energy toward the infrared seeker in order to disrupt its operation and break its ability to track the aircraft. In its current configuration, CIRCM includes two pointer-tracker units, two lasers, and one system processing unit. Northrop Grumman uses quantum cascade laser technology combined with a lightweight processor, with the architecture designed to limit weight, volume and electrical power requirements on aircraft. These constraints are particularly relevant for helicopters, where additional equipment can affect payload, endurance and performance in hot or high-altitude conditions. This approach distinguishes CIRCM from the Advanced Threat Infrared Countermeasure, whose weight and power demands largely limited its deployment to the CH-47F. CIRCM is designed for broader integration across helicopters, tiltrotor aircraft, and some light fixed-wing platforms. Its open architecture is also intended to allow new software or components to be introduced as hostile infrared seekers evolve, without requiring replacement of the entire aircraft self-protection suite. CIRCM is particularly relevant when aircraft operate at low altitude inside the engagement envelope of portable missile systems. When a warning sensor detects a launch, the tracking and jamming sequence is carried out automatically, reducing crew workload during situations in which reaction time may be limited. This is especially applicable during air assault, medical evacuation, tactical transport or resupply missions, where approach routes, low speeds and terrain can increase helicopter exposure. CIRCM also operates alongside missile warning systems and expendable flares, forming part of a layered defensive architecture rather than functioning as a stand-alone measure. The contract also provides a framework for adaptation over time. Modern infrared seekers are progressively incorporating improved flare discrimination and greater resistance to countermeasures. Maintaining a production line and an upgradeable architecture through 2035 therefore allows the US Army to modify software, jamming techniques, and selected components as the threat environment changes, while limiting extended interruptions in system availability. From a geopolitical perspective, the decision reflects continued US attention to helicopter survivability as portable missiles and short-range air defense systems remain widely distributed. Their mobility, relatively low cost, and ability to threaten aircraft at altitudes commonly used for tactical missions make them a persistent consideration for Western armed forces. Sustaining US production through 2035 also preserves options for allied procurement and Foreign Military Sales. In Europe, the Middle East and the Indo-Pacific, CIRCM is therefore part of a broader shift toward aircraft self-protection architectures designed to remain effective against a growing range of infrared-guided threats.
