Second Batch of German K130 Corvettes to be Equipped with Hensoldt’s TRS-4D Radar

ULM, Germany — Hensoldt will equip the second batch of German Navy’s K130 corvettes with the TRS-4D Rotator naval radar and MSSR 2000 IFF iden­ti­fi­ca­tion system. The com­pa­ny was award­ed a cor­re­spond­ing order for seven sys­tems of each type from the German pro­cure­ment author­i­ty BAAINBw, which are to be deliv­ered by 2022.

“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.
