Germany’s Diehl Defence has unveiled the Cobra 600, a jet-powered unmanned launch platform for the IRIS-T missile, giving ground-based air defense units a forward-positioned firing node that can expand engagement reach and complicate enemy attack planning.
Displayed at ILA Berlin Airshow 2026 from 10 to 14 June, the Cobra 600 is designed as an airborne launch rail rather than a combat drone. Its military value lies in reshaping networked air defense geometry by moving the missile launch point away from fixed radars and launchers.

The air vehicle is 600 cm long, which explains the Cobra 600 designation, and uses a full-delta-wing configuration intended to be powered by four turbojet engines. However, the ILA demonstrator was shown with two installed engines because the other two had been removed for another company project. The displayed engines were JetCat P1000-PRO micro turbojets, each producing just under 250 lb of thrust. The design has wingtip vertical stabilizers, retractable tricycle landing gear, and is intended for runway recovery, with possible use from shorter prepared strips or suitable highway sections. The available public data does not yet include maximum speed, service ceiling, endurance, fuel load, radar cross-section, or unit cost, which are all central to judging its practical combat utility.
The armament is a single IRIS-T missile carried on a top-mounted rail, using a Eurofighter-type pylon interface. That choice is technically important because it avoids creating a wholly new missile carriage arrangement and uses an existing NATO combat aircraft weapon interface. IRIS-T itself is 2,936 mm long, 127 mm in diameter, has an approximate maximum range of 25 km in air-to-air use, and reaches about Mach 3. Its guidance package combines an imaging infrared seeker, proximity fuze sensor, target discrimination and flare rejection, with thrust-vector control and lock-on-before-launch or lock-on-after-launch employment. In effect, Cobra 600 does not add a new interceptor; it changes where the existing interceptor begins its flyout.
The difference between missile range and carrier range is the core of the concept. Cobra 600 has an approximate range of 250 miles with the missile fitted, compared with around 25 miles for IRIS-T SLM and about eight miles for IRIS-T SLS in ground-launched roles. Diehl lists the IRIS-T SLM envelope at up to 40 km range and 20 km altitude against aircraft, helicopters, cruise missiles, and drones, but that figure describes the missile’s engagement envelope after launch, not the geographic distance from a base at which a battery can threaten targets. By carrying IRIS-T forward before launch, Cobra 600 can create engagement zones beyond the line where a conventional launcher would be expected, although the missile remains a short-range, high-agility weapon after separation.
The most likely employment model is a networked engagement tied to an existing IRIS-T SLM or SLS fire unit. A radar such as TRML-4D, Giraffe, CEAFAR, or another compatible sensor detects and tracks the target, the tactical operations center assigns a launch opportunity, and Cobra 600 is directed by datalink into a suitable intercept box. Once in position, the missile seeker either locks onto the target before launch or uses a lock-on-after-launch sequence in which target coordinates and inertial guidance place the missile into the predicted search volume before the imaging infrared seeker takes over. This gives commanders more geometry: side-on shots against cruise missiles, forward engagement against one-way attack drones, and coverage of terrain corridors where a ground launcher’s missile would otherwise spend energy climbing or turning. It also creates dependency on secure communications, target-quality tracks, and careful rules of engagement.
Cobra 600 can move a missile away from the defended radar and launcher, which complicates enemy planning and reduces the need to place a full firing unit close to the threat axis. It can also loiter in a sector and wait for cruise missiles, helicopters, armed drones, or low-flying aircraft rather than requiring an immediate launch from the ground. However, the current Cobra 600 has no onboard sensors, so it cannot independently search, classify, or identify targets; its only organic target-acquisition device is the IRIS-T seeker once the weapon is prepared for engagement. Against fast aircraft, the unmanned aerial vehicle’s position before the raid begins will matter more than its sprint speed after detection. Against ballistic missiles, there is no indication that Cobra 600 changes the limitations of the baseline IRIS-T air-to-air missile.
The cost and ammunition expenditure question remains unresolved. IRIS-T is not an economical answer to every small drone, particularly if the target is a low-cost decoy or a small one-way attack drone. Cobra 600, therefore, appears more relevant for threats where geography, warning time, and target value justify using an IRIS-T from an airborne firing position: cruise missiles approaching critical infrastructure, helicopters operating near the forward edge, reconnaissance drones at medium altitude, or strike aircraft forced to operate along predictable terrain corridors. The key issue is whether this unmanned missile carrier reduces the number of high-value radars and launchers that must be exposed near the forward line. It may also serve as a decoy or deception asset, but that role would depend on its radar and infrared signature, which have not been disclosed.
The industrial context is also relevant: Diehl and Polaris signed their cooperation agreement at the Paris Air Show in June 2025, with Helmut Rauch, CEO of Diehl Defence, and Dr. Alexander Kopp, CEO of Polaris Raumflugzeuge, identifying AirLAS as a way to integrate IRIS-T with reusable unmanned carrier aircraft; first flight tests were planned for that year. Cobra 600 has already flown with a dummy IRIS-T, and development is mainly company-funded, with investment from at least one interested nation. In January 2026, Diehl was moving to increase production capacity for IRIS-T SLM and SLS firing units to as many as 16 per year within roughly two years, while the IRIS-T family had reached 21 user countries. Cobra 600 should therefore be read less as a replacement for ground-based air defense and more as an attempt to distribute launch points, preserve scarce firing units, and make the defended airspace less predictable for an attacker.
