STIR is a medium-to-long range tracking and illumination radar system.
The STIR has been designed primarily to control point and area defence missile systems such as NATO Sea Sparrow, ESSM and Standard Missiles (SM1 and SM2).
A secondary application is the direct control of various calibre guns. All STIR configurations have optional TV/IR tracking capabilities. STIR technology stands for high accuracy, excellent performance and extensive ECCM capabilities.
STIR is a well-proven system. More than 150 systems have been sold and are operational. Eleven navies, amongst which are six navies of the NATO alliance, use these systems.
