Estonia has received its first IRIS-T SLM medium-range air defense system from Diehl Defence, marking a major advancement in the nation’s layered air defense architecture.
Delivered to the Air Defence Wing at Ämari Air Base, the system extends defensive coverage well beyond the capabilities of Estonia’s short-range air defense assets. Designed to counter aircraft, helicopters, and cruise missiles, the IRIS-T SLM can engage targets up to 40 kilometers away and at altitudes of up to 20 kilometers.
A standard fire unit includes multiple missile launchers, a surveillance radar, and a command-and-control center, along with support vehicles responsible for maintenance, spare parts, and missile replenishment. Its mobile configuration enables rapid deployment and repositioning as battlefield conditions evolve.
The purchase forms part of Estonia’s largest-ever defense investment package announced in 2023, which includes three IRIS-T SLM systems. The remaining units are expected to enter service during the coming year.
Brigadier General Riivo Valge highlighted the system’s high-altitude interception capability as a significant advantage, ensuring comprehensive protection against threats operating above the reach of conventional short-range systems.
Featuring full 360-degree coverage and the ability to engage multiple targets simultaneously, the IRIS-T SLM delivers strong operational flexibility with a compact crew requirement. Diehl Defence states that the system has demonstrated a success rate of more than 95 percent against aerial threats in combat conditions in Ukraine.
Estonia’s procurement is linked to the European Sky Shield Initiative, launched by Germany in 2022 to strengthen continental air defense cooperation. Through the framework, eight participating nations have selected the IRIS-T SLM, benefiting from coordinated procurement and shared support arrangements.
