The Ukrainian army began to use the German IRIS-T SLM air defense system. The medium-range air defense system IRIS-T SLM was created on the basis of an aviation missile by Diehl Defense. The air defense system began to be mass-produced in 2014, but so far it has not yet been adopted by Germany. The complex uses only the Sweden version and Egypt. Perhaps the supply of air defense systems to Ukraine will help the sales of the complex on the world market. The IRIS-T SLM air defense system is a cross between the Russian Buk-M3 and TOR air defense systems. The complex uses IRIS-T air-to-air missiles. They are equipped with an infrared homing head used at the final stage of the missile's flight, the missile's speed is Mach 3. The launch range of the IRIS-T SLM missile is 40 km, the reach in height is 20 km. Judging by expert opinions, the complexes are inferior in some ways and superior in some respects to the air defense systems of Russia. There are many opinions on them, but so far air defense systems are not very popular on the market. Among the shortcomings, the possibility of recapturing the target with an infrared head at low altitudes is noted, but all this is guesswork, since the complexes did not participate in hostilities. The standard equipment of the air defense system includes a command post, radar and launchers with anti-aircraft missiles. The cost of the IRIS-T SLM complex is 178 million euros, missiles are 400 thousand euros.
