The IRIS-T SL (Infra Red Imaging System Tail/Thrust Vector Controlled Surface Launched) is a family of short and high to medium air defense surface-to-air missile systems. The missile systems are developed from the IRIS-T air-to-air missile. Two variants and their derivatives are at the moment in service. Those two variants are IRIS-T SLS and the IRIS-T SLM, respectively Surface Launched Short range and Surface Launched Medium range.

The IRIS-T SLS, known locally as the Robotsystem 98 (RBS 98) entered service in 2020 after a trial period. The IRIS-T SLM entered service in 2022 with Ukraine, and later with Egypt.

The IRIS-T air defence system is designed to defend an area from aircraft (including jet fighters), helicopters, cruise missiles, drones, all of which can be stealthy.
