Northrop Equips German Chinooks with Lasers

Germany's acquisition of 60 CH-47F Chinooks, valued at approximately $8.5 billion, is a significant modernization of their heavy-lift capability, replacing the long-serving CH-53G fleet. This move also enhances interoperability within NATO, as many member nations already operate the Chinook platform. The deal is part of a larger €100 billion fund to upgrade the German armed forces. At the heart of the Chinook's defense is the AN/AAQ-24(V) Directional Infrared Countermeasure (DIRCM) system, of which CIRCM is the latest evolution. This isn't just a flare dispenser; it's a high-speed, closed-loop system. The BAE Systems-produced AN/AAR-57 Common Missile Warning System (CMWS) first detects a missile launch using electro-optical sensors. Once a threat is detected, the CMWS passes the missile's trajectory to the CIRCM processor. This is where the system's embedded control logic shines, slewing a pointer/tracker to lock onto the incoming threat in milliseconds. The system then engages a laser to jam the missile's seeker, steering it away from the helicopter. The key enabling technology for CIRCM's effectiveness is its Quantum Cascade Laser (QCL). Unlike older, bulkier solid-state lasers, QCLs directly convert electrical current into infrared radiation, making them more compact, reliable, and suitable for the size, weight, and power (SWaP) constraints of a helicopter. This solid-state source allows for rapid, simultaneous jamming of multiple threats. For those interested in the local Southern California defense ecosystem, the QCL technology within Northrop Grumman's CIRCM is supplied by Leonardo DRS. Leonardo DRS has a significant presence in the region, including an Electro-Optical & Infrared Systems facility in Cypress, CA, that focuses on developing and producing sensor systems for intelligence, surveillance, and reconnaissance (ISR) and targeting. The CIRCM system is designed with a Modular Open System Approach (MOSA). This is a critical concept in modern defense electronics, allowing for rapid upgrades and insertion of new technologies to counter evolving threats without a complete system redesign. This architecture ensures the system can be adapted with new jam codes and processing capabilities to keep pace with adversaries. This defensive suite provides a significant survivability boost, especially against man-portable air-defense systems (MANPADS), which are a primary threat in low-altitude operations. The CIRCM has already been extensively fielded by the U.S. Army on its own helicopter fleets, including Apaches, Blackhawks, and Chinooks, logging tens of thousands of operational flight hours.
