Saab Receives Additional Order to Supply Sea Giraffe AMB Multi Mode Radar for U.S. Coast Guard’s Offshore Patrol Cutter

Saab has received an additional order from the U.S. Navy to supply the Sea Giraffe AMB Multi Mode Radar (MMR) for the U.S. Coast Guard’s newest class of ship, the Offshore Patrol Cutter (OPC).

Saab received the initial order for the MMR for the Offshore Patrol Cutter from the U.S. Navy in 2017.

The MMR system is a three dimensional, electronically scanned phased array radar providing high-radiated power, selectable waveforms, and modern signal processing to consistently deliver the highest performance across various maritime environments and missions.

“Variants of the Sea Giraffe AMB are currently included in four separate U.S. military and homeland security programs. We are pleased that the U.S. Navy and Coast Guard continue to trust Saab to deliver world leading sensor performance and total situational awareness, even in the most challenging maritime environments,” says Anders Carp, Senior Vice President and head of Saab business area Surveillance.

Saab has sold Sea Giraffe in various configurations to customers around the world, including Sweden, Poland and the US.

In addition to supplying the MMR to the U.S. Coast Guard’s Offshore Patrol Cutter, Saab’s Sea Giraffe AMB radar, which has the U.S. designation AN/SPS-77, is currently deployed on the U.S. Navy’s Independence-class Littoral Combat Ship (LCS).  Additionally, Saab is developing a derivative of Sea Giraffe AMB (AN/SPS-77), known as AN/SPN-50, to meet the U.S. Naval Air Systems Command’s (NAVAIR) shipboard air traffic control requirements on aircraft carrier and amphibious assault class ships.

The work will be carried out by Saab in Gothenburg, Sweden and Syracuse, New York, U.S. with delivery in 2019.

Saab Sea Giraffe AMB

Sea Giraffe AMB is a multi-role medium-range 3D surveillance radar system for naval applications. It is the naval variant of the ground-based Giraffe AMB radar with 3D AMB (Agile Multi Beam) technology.

The radar provides medium range, simultaneous air and surface surveillance and also has weapon designation capability. It is suitable for demanding naval environments from the littorals to blue-water operations.

Sea Giraffe AMB can can detect air and surface targets from the horizon up to a height of 20,000 metres (66,000 ft) at elevations up to 70°, and can simultaneously handle multiple threats approaching from different directions and altitudes, including diving anti-ship missiles. Also, it is specialized for rapidly detecting small, fast moving targets at all altitudes and small surface targets in severe clutter.

The Sea Giraffe AMB is optimized for, and is in service on, vessels such as the Swedish Navy Visby Class corvettes and the U.S. Navy’s Independence class Littoral Combat Ships (LCS).
