The U.S. Navy has announced the Initial Operating Capability (IOC) status of its advanced F/A-18 IRST sensor system, developed by Lockheed Martin for the F/A-18 Super Hornet. This development marks an important step toward full-rate production following successful flight tests.
At the core of this advanced system is IRST21, a long-wave infrared search-and-track sensor designed by Lockheed Martin. The system passively detects airborne targets at distances beyond visual range, giving Naval Aviators an enhanced ability to track threats without relying on radar. This improved capability strengthens the F/A-18 IRST platform’s effectiveness and increases mission survivability.
“Achieving IOC for IRST21 is a significant milestone and a testament to the strong partnership between Lockheed Martin and the U.S. Navy,” said Paul Hey, director of Lockheed Martin’s IRST programs. “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.”
The latest version of the IRST21 system offers an extended threat-detection range. On the F/A-18 Super Hornet, the IRST sensor is integrated at the front of the centerline fuel tank, allowing it to operate without emitting signals that could reveal the aircraft’s position.
Advancing Air Combat Strategy
The IRST21 sensor represents a major leap in passive sensing technology, providing pilots with improved situational awareness while reducing reliance on active radar. This capability gives the Super Hornet an advantage in complex threat environments where stealth and early threat detection are essential.
“With this game-changing leap in passive sensing technology, IRST21 will fundamentally reshape how air warfare is conducted while keeping pilots ahead of threats,” shared Hank Tucker, vice president of Mission Systems for Lockheed Martin’s Sensors & Global Sustainment organization. “We’re proud to enhance the F/A-18 Super Hornet with an advanced IRST sensor system that ensures strategic superiority in evolving threat environments.”
With the IOC status now achieved, the U.S. Navy moves closer to full deployment of this advanced IRST system, reinforcing the F/A-18 Super Hornet’s role in modern aerial combat.
