U.S. Coast Guard’s 9th NSC will adopt Airbus Multi-Mode Radar AN/SPS-75 (TRS-3D)
Airbus Defense and Space, Inc. will provide the TRS-3D Baseline D multi-mode radar (MMR) for the U.S. Coast Guard’s ninth National Security Cutter (NSC). NSCs are 418 feet long with a 54-foot beam and displace 4,500 tons with a full load. They have a top speed of 28 knots, a range of 12,000 miles, an endurance of 60 days and a crew of 120.
The contract to provide the AN/SPS-75 MMR is with Lockheed Martin, with whom Airbus has worked to provide radars for all prior NSCs. Lockheed Martin’s intimate knowledge and experience with AN/SPS-75 technology enabled them to successfully integrate the radar with all systems required by the NSC program, and that experience carries forward into the current contract.
Since its introduction in 1995, the radar became a global sales leader with more units being sold than any radar in its class. In the U.S. market, it is in the U.S. Navy inventory aboard Freedom-variant Littoral Combat Ships and in the Coast Guard inventory aboard all NSCs, as well as at the service’s shore-based training center in Petaluma, Calif. Its design has matured over the years to meet evolving customer requirements and keep pace with advances in technology.
The TRS-3D Baseline D, designated AN/SPS-75, utilizes gallium nitride (GaN) technology to deliver traditional TRS-3D robust performance while improving reliability and options for future development. Airbus TRS-3D radars have been aboard every NSC since the program’s inception.
Employing state of the art GaN technology, the TRS-3D is a three-dimensional, multi-mode naval radar for air and surface surveillance, target acquisition, self-defense, gunfire support and aircraft control. It automatically detects and tracks all types of air and sea targets, alleviating crew workload requirements. Life cycle affordability is further enhanced by the reliability of the AN/SPS-75’s solid-state system design, keeping maintenance costs low and further contributing to lower lifecycle costs.
