US Navy Orders 12 Infrared Search & Track (IRST) Systems for its F/A-18 Super Hornet
 
The U.S. Navy recently placed an order with Boeing for the procurement of 12 low-rate initial production Infrared Search and Track (IRST) systems. Intended for the F/A-18 Super Hornet, the IRST system provides "see first, strike first" capability. It was developed and integrated by Boeing and Lockheed Martin and initally received approval from the U.S. Navy to enter low-rate initial production in January 2015.

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.

IRST is expected to deploy on the F/A-18 Super Hornet in 2017.

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.

Contacted by Navy Recognition, a Boeing Defense spokesperson explained that "the IRST Pod carries 330 gal of fuel in the fuel tank assembly". This means that the pod still acts as an external fuel tank and the IRST feature does not sacrifices range much.
