May 26 (UPI) — Boeing has received an $89 million contract to incorporate the Block II Infrared Search and Track System, or IRST, in the F/A-18 E/F Super Hornet, the Department of Defense announced on Thursday.

The contract includes design and development, hardware procurement, technical reviews, risk reduction, and product support and engineering tasks.

Work will be conducted in Orlando, Fla., and St. Louis, Mo. The project is expected to be completed by April 2020. Navy Fiscal 2017 research, development, testing, and evaluation funds of $21 million will be allocated to the program at the time of award, none of which will expire at the end of the fiscal year.

The IRST is designed to locate the heat emitted by aircraft engines without the use of active radar, which is easily detected by enemy planes and ships. It also helps countering stealth technology.

The system has already seen service aboard a King Air test-bed aircraft.

The Super Hornet fighter is the primary Navy and Marine Corps aircraft, capable of land and carrier-based operations. The plane is expected to be upgraded and in use until the 2040s.

A Brief Note on IRST & F/A-18

An IRST is a technique for detecting and tracking objects, which give off infrared radiation such as jet aircraft and helicopters. Starting 1980s, IRST systems resurfaced on modern designs with the introduction of 2-D sensors that cued both horizontal and vertical angle. Enhanced sensitivities lead to better resolution and range.

Boeing’s F/A-18 Super Hornet – a twin-engine, supersonic, all weather multirole fighter jet – is the U.S. Navy’s primary strike and air superiority aircraft. It is capable of landing and taking off from an aircraft carrier. F/A 18E is a single-seat variant of the Super Hornet, which is about 25% larger than its predecessor, the F/A-18C/D, but contains 42% lesser structural parts.

Notably, the F/A-18 IRST system incorporates Lockheed Martin Corp.’s LMT IRST21 sensor, GE Electronics Company’s GE FPU-13 Fuel Tank Assembly and the Meggitt Defense Industry Environmental Control unit. Source nasdaq.com
