IRST21 Sensor System

IRST

IRST21 is a passive long-range sensor system that uses infrared search and track technology to detect airborne threats and provide weapon-quality track solutions on those targets. Even in electronic attack environments, IRST21 provides autonomous, accurate tracking data to enhance pilot survivability by enabling see first, strike first capability.

IRST21 is compact enough to mount in various locations, from a conformal fuselage mount to a pylon. Lockheed Martin is developing an IRST21 system that will be transportable across a variety of platforms including the F-16, F-15C and F/A-18.
