 The biggest mystery of the latest aid package from Germany to Ukraine, laser targeting for Iris T SLM. The German government has officially announced the provision of another aid package to Ukraine. The package includes an additional six Gepard self-propelled anti-aircraft guns, ammunition of various calibres, including 155mm Vector drones, Bieber engineering vehicles and other equipment. However, this package contains a real mystery according to Defense Express. 10 laser illuminators for Iris T SLM have been added to 10 Iris T SLM fire-controlled stations referred to as Laser Zeilbeluchta in the original text and laser-aiming equipment in the English version of the announcement. And this is really a mystery due to the fact that Iris T SLM uses infrared guided missiles and not by a reflected laser beam. That is, there is no need to illuminate the target with a laser for the Iris T missile. However, the developer Deal declares extremely high sensitivity of the missile's seeker head which can detect not only the high temperature signature but the target itself as a whole. This allows the missile with appropriate changes to its software to engage surface targets such as boats. A corresponding successful test was conducted in 2016 by the Norwegian Air Force. Additionally, the Iris T SLM air defense system does not have a separate optical location station where a laser illuminator can be placed. The role of the passive sensor in this system is typically performed by the TWL Envis electronic reconnaissance station from Hedsalt.
