Airbus Defense and Space Inc. is under contract with Airbus DS Electronics and Border Security, to provide TRS-4D radars for the U.S. Navy’s Littoral Combat Ship (LCS) program through Freedom-class variant prime contractor, Lockheed Martin. A factory acceptance test was recently completed for the radar planned to go aboard LCS 21 ship. This follows the already planned installations of TRS-4D aboard LCS 17 and LCS 19.
The TRS-4D radar for LCS is a rotating version of the Active Electronically Scanned Array (AESA) fixed panel TRS-4D radar currently going aboard the German Navy’s F125 frigates. It combines mechanical and electronic azimuth scanning to achieve fast generation of target tracks.
The TRS-4D is a three-dimensional, multi-mode naval radar for surveillance, target acquisition, self-defense, gunfire support, and aircraft control. It automatically detects and tracks all types of air and sea targets, alleviating crew workload requirements.
