The Navy has awarded Lockheed Martin a $233 million contract for the delivery of Infrared Search and Track Block II systems, the company announced today.
The IRST21 Block II systems are a next-generation version of the IRST capability and can deliver longer range detection and fast target data, according to the company.
“IRST21 Block II delivers a game-changing leap in passive warfighting capabilities across multiple platforms,” Cristin Stengel, IRST21 program director for Lockheed Martin, said in a statement. “By significantly enhancing the range and accuracy to enable weapon employment in challenging environments, this system ensures pilots remain ahead of evolving adversaries and mission-ready at all times.”
IRST Block II aids F/A-18 E/F Super Hornet squadrons with detection and tracking of targets in certain environments where radar may prove ineffective.
The announcement follows a full-rate production decision for IRST Block II this past summer, and initial operational capability in November 2024. A full-rate production decision was originally scheduled to occur by January 2025, but was pushed back due to delays in flight testing, according to a Government Accountability Office report.
These delays were driven by software defects, causing IRST pods to falsely report overheating, according to GAO. These software issues are now resolved, a Navy spokesperson told Inside Defense in July.
