Building on decades of proven performance, Lockheed Martin has updated the sensor suite of the F-16 to even further increase its capabilities. The new variation of the IRST21 (Infrared Search and Track) sensor suite, named Legion-ES (Embedded System), is designed for the F-16 Block 70/72 fleet to optimize aircraft performance.

As a passive, long-range sensor system, IRST21 uses infrared search and track technology to detect and track airborne threats with weapon-quality accuracy, increasing pilot reaction time and improving survivability (Picture source: Lockheed Martin) |
