US Navy Approves F/A-18 IRST System Production

The F/A-18 Super Hornet infrared search and track (IRST) system, developed and integrated by Boeing and Lockheed Martin, received approval from the U.S. Navy to enter low-rate initial production.

The IRST system consists of Lockheed Martin’s IRST21™ sensor, the GE Aviation FPU-13 Fuel Tank Assembly and the Meggitt Defense Industry Environmental Control unit. The system demonstrated its production readiness through a series of extensive assessments and reviews, including flight tests.

IRST21 is the next generation of Lockheed Martin’s legacy IRST sensor system, which accumulated more than 300,000 flight hours on the U.S. Navy’s F-14 and international F-15 platforms. The long-range IRST21 sensor uses infrared search and track technology to detect, track and enable the Super Hornet to engage threats with air-to-air weapons.

In addition to detecting airborne threats, IRST significantly enhances multiple target resolution compared to radar, providing greater discrimination of threat formations at longer ranges. Data from the IRST21 sensor is fused with other on-board F/A-18 sensor data to provide maximum situational awareness to the warfighter.
