ÄMARI AIR BASE, Estonia, June 23, 2026 — Estonia has received its first IRIS-T SLM medium-range air defense system at Ämari Air Base, marking the largest defense investment in the country's history and significantly expanding its air defense capabilities.
The German-made IRIS-T SLM was procured through the Estonian Centre for Defence Investments (ECDI) under a joint acquisition program with Latvia. The system fills a key capability gap between Estonia's existing short-range air defense assets, including Mistral and Piorun MANPADS, and longer-range air defense systems.
Manufactured by Diehl Defence, the IRIS-T SLM has gained attention for its performance in Ukraine, where it has been used to intercept cruise missiles, attack drones, and aerial bombs. The system uses an imaging infrared seeker that improves target discrimination and effectiveness against low-signature threats.
The IRIS-T SLM can engage aircraft, helicopters, cruise missiles, and drones at ranges of up to 40 kilometers and altitudes of up to 20 kilometers.
Each firing unit includes multiple mobile launchers, a radar unit, a tactical control center, and support vehicles, allowing independent and mobile operations.
Brigadier General Riivo Valge, Commander of the Estonian Air Force, said the system's engagement altitude provides a capability Estonia previously lacked, preventing hostile aircraft from operating freely over its territory. He also highlighted the system's tactical mobility, which allows rapid repositioning.
The delivery is part of a €400 million contract signed in autumn 2023. Estonia ordered three firing units, with the remaining two scheduled for delivery in 2027.
Latvia signed a separate €600 million agreement for the same system as part of efforts to develop a coordinated, layered air defense network across the Baltic region. Both countries are also participating in the European Sky Shield Initiative (ESSI), launched by Germany in 2022 to strengthen European ground-based air defense cooperation.
Diehl Defence CEO Helmut Rauch said the delivery demonstrates the company's ability to meet commitments despite strong demand for air defense systems across Europe.
Although the first system has arrived, Estonian officials said it will take several months of training before it reaches full operational readiness. The Estonian Air Defence Wing, established in July 2023, continues to expand its personnel and operational capabilities, with its first conscripts beginning service in July 2026.
Defence Minister Hanno Pevkur said the war in Ukraine has highlighted the importance of modern air defense systems for protecting populations, military units, and critical infrastructure.
Estonia, which has a population of approximately 1.4 million and shares a 294-kilometer border with Russia, currently spends about 3.7 percent of its GDP on defense. Once operational, the IRIS-T SLM will become a key element of the country's layered air defense network.
