IRIS-T SLS appears in the 2014 Russia-Ukraine War record as a German-supplied Ukrainian short-range air-defense system. Germany's official Ukraine military-support list, archived at its April 17, 2025 state, recorded delivered IRIS-T SLS missiles and six delivered IRIS-T air-defense systems grouped as SLM/SLS, with ten more SLM/SLS systems and additional missiles in preparation or execution.
A September 4, 2024 German government speech at Todendorf gave a more specific fielding milestone: Chancellor Olaf Scholz said four IRIS-T SLM systems were in operation in Ukraine, together with many missiles and three related IRIS-T SLS systems. He also said Germany had contractually ordered eight more SLM systems and nine more SLS systems for Ukraine.

Timeline
The public record supports SLS fielding after the first Ukrainian IRIS-T SLM deliveries, but the most precise SLS-specific public milestone is September 2024, when Scholz stated that three related SLS systems were already in Ukraine. The same speech connected IRIS-T family operations in Ukraine with defense against Russian missiles, drones, and cruise missiles, while separating the specific SLS count from the broader family performance claim.
By March 2025, Ukraine's Ministry of Defence had signed a memorandum with Diehl Defence, the IRIS-T manufacturer, and said the agreement anticipated a threefold increase in deliveries of missiles and air-defense systems. The ministry described IRIS-T systems as an important part of Ukraine's air-defense shield.

Narrative
In Ukrainian service, IRIS-T SLS fills the short-range layer of the broader IRIS-T ground-based air-defense family. Diehl Defence describes SLS as a mobile short-range system built around the standard IRIS-T missile and intended to complement longer-range IRIS-T layers. The later SLS MK4 configuration is described by Diehl as an all-in-one short-range air-defense system for protecting troops on the move and critical infrastructure from airborne threats, with an effective range of 12 km and altitude coverage up to 6 km.
The available public record directly supports transfer and fielding of SLS systems and missiles to Ukraine, but it is less precise about SLS-only combat engagements. German and Ukrainian official sources describe IRIS-T family systems as part of Ukraine's air-defense shield against Russian aerial attacks; this page therefore treats confirmed SLS use as delivered and fielded short-range air defense, without assigning family-wide interception totals to SLS alone.
