November 28/18: More Block II Lockheed Martin is being tapped to continue to the next phase of its Boeing F/A-18E/F Super Hornet Block II Infrared Search and Track (IRST) upgrade program. Awarded by Boeing, the $108 million contract allows for the development, platform integration, flight test and qualification of the IRST21 Block II sensor system installed on the US Navy’s Super Hornet fighter aircraft. IRST21 is a multi-function sensor system that has been designed to provide long-range detection and tracking of airborne threats in radar-denied environments. It is a passive, long-range sensor system that uses infrared search and track technology to detect and track heat coming off the engines of enemy aircraft. The IRST21 autonomously detects and tracks airborne targets at long ranges, and can merge the data with the fighters’ other sensors to provide a multi-dimensional view of threats. The Navy plans to field a 170 Block II sensor across its F-18 fleet.
