Lockheed Martin Secures $233M Contract for IRST21 Block II Systems for U.S. Navy and ANG

Lockheed Martin has been awarded a $233 million firm-fixed-price contract to deliver IRST21 Block II systems and initial spares to the U.S. Navy and Air National Guard (ANG). This contract marks a significant step forward in enhancing the U.S. military's passive infrared search and track (IRST) capabilities.

What Is IRST21 Block II?

IRST21 is Lockheed Martin’s next-generation long-wave infrared sensor system designed to passively detect and track airborne targets at extended ranges. The Block II variant builds upon its predecessor with advanced optics, processors, and algorithms, significantly improving threat detection and targeting capabilities. This enhancement allows for faster target data processing, bolstering situational awareness and reducing decision-making time for warfighters.

Integration with U.S. Navy and ANG Aircraft

The IRST21 Block II system is integrated into various aircraft platforms:

• U.S. Navy F/A-18E/F Super Hornets: The system is mounted on the centerline fuel tank, providing enhanced passive detection capabilities in radar-denied environments.

• Air National Guard F-15 and F-16 Fighters: IRST21 Block II sensors are integrated into these aircraft to improve long-range detection and targeting, particularly in contested airspaces.

This widespread integration ensures that both Navy and ANG units benefit from the advanced capabilities of the IRST21 Block II system.

Strategic Importance

The IRST21 Block II system enhances the U.S. military's ability to detect and engage threats at extended ranges without relying on radar emissions. This passive detection method is crucial in environments where electronic warfare and radar jamming are prevalent. By providing early warning and targeting information, IRST21 Block II contributes to maintaining air superiority and mission readiness.

The $233 million contract for IRST21 Block II systems underscores the U.S. military's commitment to advancing its passive infrared detection capabilities. With integration across key aircraft platforms and enhanced performance features, the IRST21 Block II system is poised to play a pivotal role in modernizing the U.S. Navy and Air National Guard's operational effectiveness.
