Saab has received an order from the U.S. Navy to supply the Sea Giraffe AMB Multi Mode Radar (MMR) for the Navy’s Expeditionary Sea Base (ESB) class ship USNS Hershel “Woody” Williams (T-ESB-4).
The sale also includes Saab’s 9LV Naval Combat Management System for radar control and display delivering enhanced situational awareness as well as Identification Friend or Foe (IFF) capability.
The ship will be operated by the U.S. Navy’s Military Sealift Command (MSC). In 2017, the U.S. selected Saab’s Sea Giraffe MMR for the U.S. Coast Guard’s newest class of ship, the Offshore Patrol Cutter (OPC). The MMR is a 3D, electronically scanned phased array radar providing high-radiated power, selectable waveforms, and modern signal processing to consistently achieve high performance across various marine environments.
“Saab’s Sea Giraffe MMR will strengthen the U.S. Military Sealift Command’s capability by providing total situational awareness across a wide range of tasks including expeditionary warfare missions. Our naval radars are now selected on board five classes of ships in the U.S. This order demonstrates the Navy’s continued confidence in Saab as a strong partner and radar supplier. We are proud that the Navy continues to trust Saab radars to enable its mission success across the full spectrum of maritime environments and operations,” says Erik Smith, President and CEO of Saab Defense and Security USA.
The work will be carried out during the period of 2018-2020 at Saab in Gothenburg, Sweden and Syracuse NY, U.S.
Saab is a world leader in radar and sensor technology. In addition to the U.S. Expeditionary Sea Base and Offshore Patrol Cutter class ships, 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. Saab is also developing a derivative of 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.
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).
