Ultra Installs First Sonar 2150 on Royal Navy Frigate HMS Portland

The UK Royal Navy Type 23 frigate HMS Portland (F79) becomes the first ship to be fitted with Ultra’s next-generation Sonar 2150 Hull Mounted Sonar as part of a wider refit to the RN frigates.

The sonar has been designed by Ultra Electronics Command & Sonar Systems and will replace the legacy Sonar Type 2050, which has been in the Royal Navy service since the 1990s.

The new sonar incorporates a state of the art User Interface to improve operator effectiveness and usability. The digital control of the outboard array minimizes interference, reduces ship cabling, maximizes reliability and extends array maintenance intervals to at least five years. This sonar is the third-generation hull-mount sonar for Ultra and draws on the capabilities developed for the UK Type 45 and the Australian Hobart Class destroyers, and the UK Sonar 2170 for torpedo defense.

The sonar will be fitted to eight of the Royal Navy Type 23 frigates. Ultra has also been awarded the contract to supply this sonar to the first three Royal Navy Type 26 frigates currently under construction.

As part of Ultra’s ‘Sea Searcher’ sonar range, Ultra has also developed two smaller and lighter weight variants of the Type 2150 Hull Mount Sonar for naval vessels up to 1,000 tonnes and 2,000 tonnes respectively. With state-of-the-art in-board processing and innovative user displays, this family of sonar systems provides a potent Anti-Submarine Warfare (ASW) capability for patrol vessels, frigates and other vessels worldwide.

“Reaching this significant milestone has been key for Ultra. With a number of significant changes from the Sonar 2050 system it replaces, the project team has designed and developed a system that simplifies user operability and significantly reduces life cycle costs and in board footprint. They have truly excelled themselves”, said Mike Williams, Managing Director of Ultra Electronics Command & Sonar Systems.

Ultra Electronics will also provide the UK Sonar 2150 for the BAE Systems’ Type 26 Global Combat Ship being built for the Canadian Surface Combatant (CSC) program.
