AviationNews – German aerospace startup Polaris Raumflugzeuge has successfully conducted the maiden flight of its Cobra 600 unmanned aerial vehicle over the Baltic Sea. Developed in collaboration with Diehl Defence, this innovative jet-powered drone is designed to carry and launch an IRIS-T air-to-air missile, introducing a novel, reusable approach to extending the reach of modern air defense networks.
The Cobra 600 prototype, which features a takeoff mass of approximately 600 kilograms, was developed under the joint Airborne Launching and Attack System (AirLAS) project. The recent maiden flight saw the drone cover a distance of over 20 kilometers, successfully validating its core aerodynamic design. While this initial flight was conducted without a dummy IRIS-T missile mounted on its fuselage rail, future test phases will fully integrate the payload. Polaris, a company primarily known for developing reusable hypersonic spaceplanes, adapted its specialized aerospace technology to create this defense-oriented platform alongside Diehl’s established missile manufacturing expertise.
Serving effectively as a reusable “missile taxi,” the Cobra 600 is engineered to transport a single IRIS-T missile closer to incoming aerial threats before launching it. This operational concept significantly extends the reach and effective engagement distance of the missile, empowering ground or air-based defense units to intercept hostile targets—such as fighter-bombers deploying glide bombs—long before they enter traditional defense perimeters. The drone is designed to rely on the missile’s own sophisticated tracking sensors for the final engagement, which keeps the carrier platform relatively simple and cost-efficient.
“The perfectly smooth first flight covered a distance of 20 km,” Polaris Raumflugzeuge confirmed following the test, adding that the platform “is a light uncrewed aircraft that Polaris is developing in cooperation with Diehl Defence… primarily designed to carry and launch IRIS-T air-to-air missiles for air defence missions”.
The successful maiden flight clears the path for a series of progressively complex test flights planned for the coming months, which will test the aircraft with a realistic missile payload. If fully realized and deployed, the Cobra 600 could seamlessly integrate into existing ground-based air defense systems or broader future combat air architectures, offering a flexible and cost-effective layer of interception. Diehl Defence has also indicated that the foundational technology could eventually support multi-domain operations, including maritime defense and advanced hypersonic applications.
The debut flight of the Cobra 600 prototype marks a notable milestone in the evolution of unmanned air defense technology. By combining a reusable drone carrier with a highly capable, combat-proven interceptor missile, Polaris and Diehl Defence are actively shaping the future of cost-effective aerial interception capabilities.
