JSK Naval Support has completed its first manufacturing contract for Canada’s Department of National Defense with the delivery of 66 battery packs.

The battery packs will be used to supply electricity to the emergency underwater telephones (EUWTs) installed onto the Royal Canadian Navy’s (RCN) Victoria-class submarines, which previously served as the British Royal Navy’s Upholder-class vessels.

JSK Naval Support is a joint venture (JV) between Canadian company Kaycom, which is a provider for the Canadian Government, and UK-based Cohort company SEA.

The JV secured the Victoria-class contract from Canada’s Public Works and Government Services organisation.

JSK Operations vice-president Neil Herbert said: “This manufacturing contract builds on our established work as a support organisation for the RCN, and through the transfer of IP and technology from SEA underlined the strengths that SEA and Kaycom bring to JSK.”

"The system is a combined EUWT and submarine locator acoustic beacon (SLAB) that allows survivors from a distressed submarine to indicate their position to nearby searching forces."

The equipment is part of Sonar 2073 system that has been deployed on the entire submarine fleet to be used if a boat’s power supply fails, or is initially unavailable in case of an emergency.

The system is a combined EUWT and submarine locator acoustic beacon (SLAB) that allows survivors from a distressed submarine to indicate their position to nearby searching forces by sound signals.

It enables them to establish and maintain voice communication with both surface and sub-surface units.

SEA has served as the Royal Navy’s design authority for Sonar 2073 for approximately 15 years, and has transferred the technology to JSK.
