Track radar for gun and missile fire control. Its long range tracking and missile illumination performance support ship defense with Semi Active Homing missiles such as SM2. Its design is optimized for stealth target detection in demanding littoral and ECM environments. STIR subsystems are operational on-board various types of ships with weapon applications as mentioned above and have therefore proven to meet the operational requirements for this type of product.

• Ship and area defense by early target detection and tracking. • Illumination support for Semi Active Homing missiles • Large 2.4 m dish for extended illumination range • Operation under hostile conditions featuring extensive ECCM

features • Qualified and proven system
