TRS-3D Baseline D Multi-Mode Radar for 9th NSC.

NavyRecognition reports, “Airbus Defense and Space, Inc., under contract with its affiliate Airbus DS Electronics and Border Security GmbH, will provide the TRS-3D Baseline D multi-mode radar (MMR) for the U.S. Coast Guard’s ninth National Security Cutter (NSC).”

The Bertholf Class have been equipped with the rotating Active Electronically Scanned Array (AESA) TRS-3D multi-mode (air search, surface search, helicopter control, and firecontrol) radars from the first. My understanding is that this is an improved version of the same radar that equips earlier National Security Cutters and the Freedom class LCS.

Airbus (formerly EADS) has an excellent multi-paged description of the system here.

It is not clear to me how this compares with the TRS-4D system, also from Airbus. The TRS-4D will equip Freedom Class LCS beginning with LCS-17, and I expected it to be used on the Offshore Patrol Cutter (OPC). The TRS-4D appears to be very similar in many respects, but it looks at higher elevations and is lighter. Is it a replacement for the TRS-3D or is it a “junior” version of the same technology?

  1. TRS-3D is on the flight 0 LCS. -4D is sold by Airbus as an an upgrade/modernization/replacement based on whats more likely to make the sale. -4D is C-band AESA vesus -3D’s more basic phased array. Baseline D upgrades -3D to Gallium Nitride, which in short means more efficiency, better performance.

      • Well “the best” would be something along the lines of SPY-6….

        I think the upgraded TRS-3D is a cromulent choice, going all the way to -4D would cost more and have a greater impact on the NSC design. Right this moment, I think its more important to get these hulls in the water without raising red flags with any watchdogs. Once theyre all in service, an upgrade program for the class to advance all the hulls to -4D would be worth a look.
