The US Navy has formally declared that the new infrared search and track sensor system developed by Lockheed Martin for the F/A-18E/F Super Hornet fleet has achieved initial operating capability (IOC) status.
The United States Navy has announced IOC for a cutting-edge infrared search and track (IRST) sensor system developed by Lockheed Martin for the F/A-18 Super Hornet. This milestone marks a major advancement in airborne threat detection and survivability.
At the heart of this new capability is the IRST21, a long-wave infrared sensor that passively detects airborne targets well beyond visual range. Designed to enhance situational awareness and survivability, the system provides naval aviators with a decisive edge in modern air combat.
The IOC declaration follows successful flight testing, paving the way for a full-rate production decision by the US Navy.
“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, director of Lockheed Martin’s IRST programs.
The latest iteration of the IRST21 system significantly extends detection range, giving Super Hornet pilots enhanced tracking capability against modern airborne threats. Integrated into the front of the aircraft’s centreline fuel tank, the system allows for passive detection of enemy aircraft without relying on radar, providing a critical tactical advantage.
“This advanced sensor enables pilots to detect and track airborne threats at greater distances, significantly improving mission effectiveness and survivability,” Hey added.
Hank Tucker, vice president of mission systems at Lockheed Martin’s sensors and global sustainment division, expanded on the comments made by Hey, adding, “With this leap in passive sensing technology, IRST21 will fundamentally reshape how air warfare is conducted while keeping pilots ahead of emerging threats. We’re proud to enhance the Super Hornet with an advanced sensor system that ensures strategic superiority in evolving threat environments.”
The Royal Australian Air Force operates a fleet of F/A-18F Super Hornets, making this technological breakthrough highly relevant for Australia’s air combat capability.
As the Indo-Pacific region faces increasingly complex security challenges, advanced sensor technology like IRST21 could play a vital role in maintaining air superiority.
With its ability to detect threats passively at long range, IRST21 represents a transformational capability for modern air combat, reinforcing the importance of technological advancements in Defence aviation.
