Canada has selected Thales’ S2087 towed low-frequency sonar for its future River-class destroyers, a move that confirms a major anti-submarine warfare change for the Royal Canadian Navy’s next surface combatants. The contract was awarded by Lockheed Martin Canada to Thales Canada, which will supply the system for integration on the new ships.
The S2087, part of the CAPTAS family, is designed to detect and track quiet submarines at long range in both open-ocean and coastal environments. It is already in service with Royal Navy Type 23 and Type 26 frigates, giving the Canadian program a proven NATO-standard system with established operational use.
The selection marks a turnaround in the planned ASW sonar architecture for the River-class destroyers and strengthens Thales’ role in Canada’s naval sector. The program is aimed at expanding the Royal Canadian Navy’s undersea surveillance and anti-submarine warfare capacity across complex maritime environments, including Arctic operations.
Thales and Lockheed Martin Canada said the deal advances Canada’s defense capabilities, while the contract value and delivery schedule were not disclosed.
