Denmark has strengthened its national air defense network by procuring additional IRIS-T SLM fire units under the German-led European Sky Shield Initiative (ESSI). The decision expands Copenhagen’s investment in layered ground-based air and missile defense as regional threats continue to evolve following Russia’s invasion of Ukraine. The IRIS-T SLM, developed by Diehl Defence, has already been selected as Denmark’s preferred ground-based air defense system earlier this year.
The IRIS-T SLM is a medium-range air defense solution capable of intercepting aircraft, helicopters, cruise missiles, and unmanned aerial systems at distances of up to 40 kilometers and altitudes reaching 20 kilometers. Its advanced sensors, high mobility, and precision engagement capabilities provide enhanced protection for civilians, military installations, and critical infrastructure—areas increasingly vulnerable to drone incursions and asymmetric threats.
Denmark’s procurement was conducted through ESSI’s standard contracting framework, a mechanism designed to accelerate acquisitions and reduce administrative burdens for participating nations. Established in 2022 in response to Russia’s war in Ukraine, ESSI aims to create a unified, layered air and missile defense shield across Europe. Countries such as Bulgaria, Slovenia, and Switzerland already operate or have procured the IRIS-T SLM, benefitting from joint logistical support, shared training programs, and coordinated procurement.
Copenhagen’s air defense expansion goes beyond IRIS-T. The country recently signed a $579-million contract with Kongsberg for the NASAMS medium-range system. Additionally, the United States has approved a $3.7-billion Danish request for the Integrated Battle Command System, Indirect Fire Protection Capability launchers, and 200 AIM-120C-8 AMRAAM interceptors, signaling one of Denmark’s most comprehensive modernization efforts in decades.
