The second batch of K130 corvettes will be equipped with the Hensoldt TRS-4D Rotator ship radar and MSSR 2000 ID friend or foe detection system (IFF). The Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw) has commissioned HENSOLDT to deliver a total of seven systems by 2022.
The TRS-4D Rotator is designed for anti-aircraft and anti-ship combat. Its mechanically rotating antenna offers a combination of mechanical and electronic azimuth scanning, allowing targets to be acquired and tracked very quickly. The radar's AESA technology enables precise location, especially of smaller and maneuvering objects, giving the ship's crew more time to react to threats.
The integrated MSSR-2000-I secondary identification-friend-or-foe (IFF) radar operates with all IFF standards including the latest "Mode S/Mode 5" to which all NATO forces are currently upgraded and convert their allies.
The F125 frigates are also equipped with the TRS-4D radar. Four fixed transmitter/receivers cover the observation area. Independent radiators are scanned electronically (Active Electronically Scanned Array, AESA) and can track multiple targets simultaneously.
