The test took place over several days at sea, running the sonar, detecting and tracking the âtargetâ. Despite somewhat harsh weather conditions, the Ultra test team successfully demonstrated active and passive performance in conjunction with Royal Navy personnel.
The 2150 Hull Sonar, designed by Ultra, replaces the Type 2050 Sonar, which has been in service with the Royal Navy since the 1990s. It incorporates a state-of-the-art user interface to improve operator efficiency and ease of use. Digital outboard network control minimizes interference, reduces vessel wiring requirements, aiming to maximize reliability and extends network maintenance intervals. The sonar will equip the Type 23 frigates of the Royal Navy.
As part of its âSea Searcherâ hull sonar line, Ultra has developed two smaller and lighter variants of the Type 2150 for warships up to 1,000 tonnes and 2,000 tonnes, respectively.
With state-of-the-art on-board processing and innovative user displays, this family of sonar systems brings powerful anti-submarine warfare capability to patrol boats, frigates and other ships around the world.
HMS Portland is a Type 23 frigate in service with the British Royal Navy. The ship was accepted into service by the Royal Navy on December 15, 2000 and entered service on May 3 of the following year.
Citing the Naval-Technology website, the Type 23 frigates were originally designed for anti-submarine warfare (ASW), but the addition of the Seawolf vertical-launch missile defense system and the ground-based missile Ground Boeing Harpoon has expanded its role to include anti-surface warfare (ASuW).
