Boeing's selects Lockheed's Infrared Search and Track system for Block II Super Hornets

St. Louis, USA: The Boeing Company has said that it has selected archrival Lockheed Martin's Missiles and Fire Control division, to supply up to 150 Infrared Search and Track (IRST) systems for its Super Hornet Block II aircraft. It also said that the selection of the Lockheed IRST system, aimed at an eventual IRST development contract from the US Navy next summer, follows a rigorous and competitive request for information process.

"IRST is yet another addition to the Super Hornet Block II arsenal, and it will truly change the nature of the air-to-air fight," said Capt. Donald "BD" Gaddis, US Navy F/A-18E/F and EA-18G programme manager, PMA-265. "Sensor-fused data from IRST, AESA, ALR-67 (v)3 digitally cued receiver and off board information will ensure the Super Hornet Block II dominates and survives against the most challenging air threats well past 2024."

"Integration of IRST significantly enhances the capability of the Super Hornet Block II by providing multi-spectral air-to-air targeting," said Bob Gower, vice president, Boeing F/A-18 programmes. "IRST, a key component of the Super Hornet's 'Flight Plan,' will provide the warfighter with unprecedented on-board situational awareness and enhance the engagement range of modern high-performance air-to-air weapons."

The 'Flight Plan' is a roadmap of planned capability enhancements that will allow the Super Hornet Block II to remain ahead of emerging threats, while addressing warfighting needs in an integrated, cost effective manner, said a Boeing statement.

Historically, the F/A-18 has evolved three variants: A/B, C/D, and E/F. The A, C, and E models are single seat aircraft; the B, D, and F models are two seat aircraft. The A/B and C/D models are currently in service with the US Navy and the Marine Corps. Seven international allies of the US have also procured the F/A-18.

The E/F models are currently in the last year of engineering and manufacturing development.

The IRST
IRST is a passive, long-range sensor system that searches for, and detects, long-wave IR emissions within its field of view. It can track several targets simultaneously and provide an effective air-to-air targeting capability, even when facing advanced threats with radar jamming equipment.

Boeing will conduct a prototype flight demonstration in the first quarter of 2008, using a modified 480-gallon centerline fuel tank to house the IRST system. The modified fuel tank provides a cost effective, software-only integration approach, requiring no structural or wiring changes to the aircraft. This supports potential integration of IRST on existing and future F/A-18E/F/G aircraft.

The production system will contain more than 330 gallons of fuel in addition to providing the IRST capability. First production deliveries of IRST systems are expected in 2012, with initial operational capability anticipated in 2013.
