Ultra to provide hull-mounted sonar for CSC

19th February 2021 - 11:30 GMT | by The Shephard News Team

‘Substantive manufacture and delivery’ deal includes technology transfer to Canada, says Ultra.

Ultra Electronics Maritime Sonar Systems will provide its S2150-C Hull-Mounted Sonar (HMS) system for the Canadian Surface Combatant (CSC) programme, under a new subcontract from Lockheed Martin Canada.

This contract came about two weeks after Lockheed Martin Canada awarded Ultra a subcontract to provide a variable-depth sonar for the 15-vessel programme.

These subcontracts move development of the ASW capability for CSC from the programme definition phase ‘into the substantive manufacture and delivery of the vessels’ suite of sonars’, Ultra noted on 18 February.

Technology for the HMS (pictured) will now be transferred to Canada, meeting one of the key economic and industrial objectives of the CSC programme for the government.

As a combined active/passive array sonar for ASW, mine-avoidance and torpedo defence, the S2150 is already used on UK RN Type 26 frigates (which share design features with the CSC) as well as the Royal Australian Navy (RAN) Hobart-class destroyers.

Sixteen of the sonars have been ordered by the RN and 12 by the RAN, according to Shephard Defence Insight. 

With the same HMS family used by the RN and RAN, Canadian suppliers ‘will have the opportunity’ to be considered as suppliers to the Type 26 and Hobart-class programmes, ‘thus lifting the export potential Canadian industry as a result of CSC’, Ultra claimed.
