 Starting with LCS-17, the "Freedom"-class ships will be equipped with the TRS-4D naval radar.The TRS-4D is an AESA radar built by Airbus Defense and Space that is similar to the one on German s, the difference being the LCS will have a rotating version instead of a fixed panel, the first AESA rotating radar aboard a U.S. Navy ship.It is a three-dimensional, multi-function naval radar combining mechanical and electronic azimuth scanning that delivers increased sensitivity to detect smaller targets with greater accuracy and faster track generation.
