Hensoldt Inc. Vienna, a Hensoldt subsidiary in the State of Virginia, has been upgraded with success the first two TRS-4D radars in the LCS ships of the Freedom Class (LCS = Littoral Combat Ship) of the US Navy. After successful acceptance LCS 17 was USS 'Indianapolis' Lockheed Martin and Fincantieri Marinette Marine handed over to the US Navy in July. It should be provided as the ninth ship, Freedom' variant of the LCS on October 26 in service. The onboard the LCS 19 USS "St. Louis "installed second radar is currently being prepared for the loss.

For the LCS ships the TRS-4D ( "SPS-80 AN /" under the name of the US Navy) provided with a rotating AESA antenna with electronic scanning, while the radar is currently fixed in the German F125 frigate with an antenna is surrounded by scaffolding. The TRS-4D is the first rotating AESA radar on board a ship of the US Navy. Currently, eight TRS-4D systems for the LCS ships of the Freedom class under contract. Six of them have already passed the factory acceptance. The new radar offers a combination of mechanical and electronic azimuth scan so that targets can be confirmed quickly.

The LCS class specially developed for the offshore use and for an order-specific adaptation, consists of two variants of, Freedom 'and the' Independence '. 'For the trimarans of Independence (127 meters lan, 30 meters wide, 3,100 tons displacement, up to 45 knots), of which so far 19 units have been ordered (delivery horizon 2025) draws Austal USA, Mobile, Alabama, in collaboration with General Dynamics responsible. Those Freedom' variant, were appointed by the provisional 16 is built by Lockheed Martin, Marinette, Wisconsin, together with Fincantieri subsidiary FMG. The 115 meters long, 17.5 meters wide monohulls this variant should be able to reach up to 47 knots at a displacement of 3500 tons.

Thanks to an innovative modular design, they are interpretable for fighting Überwasserseezielen, submarines and for mine countermeasures. They can adapt to changing threats and scenarios in their lifetime. Hensoldt has inserted into this concept so far that programmable changes can be made to the software of the radar of the US Navy. This makes it possible to adjust the radar to changing the course of the ship's service life threats. Thus, the modularity of the LCS and adaptability is supported on scenarios by the radar interpretation.
