Hensoldt TRS-4D Radar for New Batch of K130 Corvettes
Second Batch of German K130 Corvettes to be Equipped with Hensoldt’s TRS-4D Radar
“With the TRS-4D, the corvettes will be given an extremely powerful radar system which has already proven its capabilities, especially in the difficult environment of coastal waters,” said Hensoldt CEO Thomas Müller. The TRS-4D is already being used on board the new F125 frigate, in a configuration comprising four fixed planar arrays. Moreover, Hensoldt previously equipped the first K130 batch with its TRS-3D radar.
For the second batch of five ships, 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 U.S. Navy’s Freedom-class Littoral Combat Ship (LCS). This radar system is part of a family of products that also includes a ground-based air defense radar — the TRML-4D — and thus benefits from continuous product improvements and advantages with regards to spare parts management and training.
The TRS-4D was designed to be used in anti-aircraft and anti-surface operations. Its rotating antenna combines mechanical and electronic azimuth scanning, which allows targets to be detected and tracked quickly. Thanks to the increased sensitivity of the radar system’s AESA technology it is possible to detect small and maneuvering targets more precisely and to confirm the targets more quickly, which means that the ship crew has more time to respond to threats.
As the system’s characteristics can be defined via its software (aka it’s “software defined”), the radar can be programmed for specific operations and its parameters be set according to the customer’s requirements. It can also be adapted to any new or modified threats that may arise over the useful life of the ship.
The system also includes an MSSR 2000 secondary radar for IFF operation, which complies with all IFF standards, including the latest “Mode S / Mode 5.” At present, all NATO troops and their allies are in the process of converting their IFF systems to Mode 5, as this standard is required for joint operations with NATO and other allied forces.
