Hensoldt TRS-4D ROTATOR Passes Factory Acceptance Test

Seven Radars for German Navy Second Batch K130 Corvettes

Hensoldt is in full production of the seven TRS-4D ROTATOR naval radars for the second batch of K130 corvettes under construction for the Germany Navy, the company announced on 1 August. The system successfully passed factory acceptance tests by the BAAINBw, the Bundeswehr procurement authority, only six months after the contract was issued.

With the TRS-4D, the corvettes are getting an extremely powerful radar system […] Since we have started to produce our radars in series a short time ago, we have been able to reduce the time required for delivery to our customers considerably,” commented Hensoldt CEO, Thomas Müller.

Hensoldt has orders for seven radars, which are intended for five ships and two land-based systems and are to be delivered by 2022. The company previously equipped the first K130 batch with its proven TRS-3D radar. For the second batch, the TRS-4D has now been ordered, to be supplied in a version comprising a mechanically rotating antenna (TRS-4D ROTATOR), which is also under contract for the US Navy’s littoral combat ship (LCS). On board the new F125 frigate, the TRS-4D is used in a configuration comprising four fixed planar arrays. This radar system is part of a family of products which also includes a ground-based air defence radar, the TRML-4D. It thus benefits from shorter production cycles and continuous product improvements, as well as advantages in stock levels of spare parts and training.

The TRS-4D ROTATOR has been designed for both anti-aircraft and anti-surface operations. Its rotating antenna combines mechanical and electronic azimuth scanning, which allows targets to be detected and tracked very quickly. Thanks to its higher sensitivity, the active electronically scanned array (AESA) radar allows more precise detection, especially of small and manoeuvring objects, as well as faster confirmation of the target, which means that the ship’s crew has more time to respond to threats. The radar can be specifically programmed for customer-specific needs, and its characteristics can be changed via the software to match new requirements that arise during its service life.

The system also includes an MSSR 2000 I secondary radar for identification friend-or-foe (IFF), which complies with all IFF standards, even the latest Mode S/Mode 5 – all the more important as all NATO forces are currently in the process of converting to Mode 5, which capability enables troops to take part in joint and combined operations.
