Lockheed Martin has received a $991-million Pentagon contract to deliver 432 electronic warfare modification kits for F-35 Lightning II fighter jets. The upgrades are expected to support the Block 4 modernization program, which enhances the aircraft’s ability to detect, jam, and counter advanced enemy radar and missile threats. The kits will be installed across US Air Force, Navy, and Marine Corps F-35 variants, as well as international partner fleets. The upgraded AN/ASQ-239 electronic warfare suite is designed to improve battlespace awareness and survivability against increasingly sophisticated air defense systems developed by countries such as China and Russia.
