Airbus Defense and Space has been contracted to deliver additional TRS-4D naval radar for the US Navy’s littoral combat ship (LCS) programme.

Intended for Freedom-class LCS, the TRS-4D radar is a rotating version of the active electronically scanned array (AESA) fixed panel TRS-4D radar, currently used on the German F-125 class frigates.

The new three-dimensional, multi-mode naval radar combines multiple capabilities within a single system, and enables rapid generation of target tracks.

Airbus Defense and Space president Mike Cosentino said: "Superior performance and adaptability for the future are key characteristics of the TRS-4D radar.

"It supports the LCS evolution to a frigate, meets current and future threats, and can readily be adapted to change over the service life of the ship."

The new radar will be equipped on LCS-21 after the scheduled installations of TRS-4D aboard LCS-17 and LCS-19.

"Superior performance and adaptability for the future are key characteristics of the TRS-4D radar."

The three-dimensional, multi-mode naval radar can be deployed for surveillance, target acquisition, self-defence, gunfire support, and aircraft control.

It is also capable of automatically detecting and tracking all types of air and sea-targets in support of LCS reduced crew sizes.

The radar is user-programmable, while its AESA technology boosts sensitivity, and enables precise detection of smaller targets and faster track generation.

Complying with the existing LCS requirements, the TRS-4D can be deployed for LCS missions and threats as they vary in the short and long-term.
