The US Navy has formally declared Initial Operational Capability (IOC) for the next-generation infrared sensors designed for the F/A-18 Super Hornet.
Developed by Lockheed Martin, the long-wave Infrared Search-and-Track (IRST21) sensor is capable of passively locating a wide range of airborne threats beyond visual range.
It is expected to extend the threat detection range of the Super Hornets, significantly enhancing both survivability and operational effectiveness.
“Achieving IOC for IRST21 is a significant milestone and a testament to the strong partnership between Lockheed Martin and the US Navy,” said Paul Hey, Lockheed IRST program director.
“This advanced sensor provides a critical capability to detect and track airborne threats at greater distances, ensuring pilots can complete their missions with enhanced situational awareness and survivability.”
With the IOC declaration, the IRST21 is now one step closer to a full-rate production decision.
‘Reshaping Air Warfare’
The IRST21 sensor builds on Lockheed’s proven legacy IRST systems, which have reportedly accumulated more than 300,000 flight hours on F-14 and F-15 platforms.
It detects heat sources across a large “field of regard,” even in environments with electronic countermeasures.
Boasting weapon-quality tracking and detection accuracy, the sensor is said to enhance pilot reaction time and improve the effectiveness of precision strikes.
Hank Tucker, Vice President of Mission Systems for Lockheed’s Sensors & Global Sustainment division, described the IRST21 as a “game-changing leap” in passive sensing technology, fundamentally transforming how air warfare is conducted.
“We’re proud to enhance the Super Hornet with an advanced sensor system that ensures strategic superiority in evolving threat environments,” he added.
Lockheed plans to provide up to 170 IRST21 sensor systems to the US Navy to support its operations.
