The new surface-to-air guided missile IRIS-T SL (Surface Launched) is an upgraded version of the IRIS-T air-to-air missile. Compared with IRIS-T, IRIS-T SL has an enhanced rocket motor, an aerodynamic hood for extended range, a data link as well as an autonomous GPS/INS navigation system. The missile's vertical launch enables comprehensive 360° protection against aircraft, helicopters, drones and missiles (no ballistic rockets). Thus, the target spectrum is the same as that of IRIS-T. The guided missile IRIS-T SL is designed for easy integration into existing and future air defence systems. This is accomplished by seamless connection to fire control systems via standardized and software-based interfaces. The launch canister intended for missile launch is simultaneously used for missile storage and transport.
The technical and operational validation of guided missiles is carried out by the Hardware-in-the-Loop-Simulation (HIL). Due to the high cost of free-flight testing, simulation regarding missile design and validation as well as the respective guidance and control section has proved to be an extremely effective and economic solution.
Tactical and technical training as well as logistic support during the entire life cycle complement the service portfolio.
Diehl Defence was tasked by the German Armed Forces to develop the IRIS-T SL guided missile for the Bundeswehr´s Tactical Air Defence.
