Victoria class Modernization
Project Summary

Canada’s four Victoria-class submarines form the core of the Royal Canadian Navy’s (RCN) underwater surveillance capabilities. Covert, well-armed, and capable of patrolling vast distances, these submarines provide support to maritime law-enforcement in investigating narcotics trafficking, smuggling, and polluting cases, as well as conducting domestic and international operations.
Four Victoria-class submarines were purchased from the British Government in 1998, and delivered to Canada over a four-year period from 2000 to 2004. The first three submarines—Victoria, Windsor and Corner Brook—were commissioned into RCN service shortly after their arrival in Canada. The fourth, Chicoutimi, was delivered to Canada in 2004, but was not commissioned into RCN service until 2015, due to a fire in 2004 and subsequent work required.
Through the Victoria-class Modernization (VCM) project, these submarines will be modernized to allow them to continue operating in an evolving environment into the mid-to-late 2030s.
VCM is currently made up of 12 separate equipment upgrade projects. Eight are in the implementation phase and four are in the definition phase.
Most of the equipment acquisition and in-service support will be managed through separate contracts. Platform integration and installation of VCM equipment is primarily managed under the Victoria Class In-Service Support Contract (VISSC), a long-term contract with Canadian Industry.

Industry
Benefiting Canadian Industry
Three Requests for Information have been released to industry to gain insight into costs and availability for the Periscopes Modernization Project.
Industry engagement plans for the Flank Array Modernization Project and Periscopes Modernization Project were approved by the Director General Governance Committee on 09 March 2021.
Industrial Technological Benefits will be considered for all acquisitions in excess of $20M.
Canada will continue to engage with stakeholders on advancing industrial and technological benefits for companies in Canada, and promoting innovation, ensuring best value and supporting Canada’s defence priorities.

About the Victoria-class Submarines
Home ports:
- Esquimalt, British Columbia
- Halifax, Nova Scotia
Facts and figures:
- Length: 70.3m
- Displacement (weight): approximately 2,200 tonnes surfaced / 2,450 tonnes dived
- Speed: 12 knots (surfaced), 20 knots (submerged)
- Patrol Endurance: approximately 8 weeks
- Driving Depth: > 200 metres
- Crew size: 48 crew and 5 trainees
Fleet Status
The Repair Work Period for the HMCS Victoria was completed in late 2020. The Transition Docking Work Period for HMCS Windsor was completed in 2021. Both submarines are now in a normal readiness posture, meaning they are capable of supporting domestic operations on short notice, although their primary focus is on trials and training needed for high readiness.
Modernization of the Victoria-class will make Canada and its allies stronger and safer by:
- Improving the habitability and deployment conditions onboard the VCS for Royal Canadian Navy (RCN) submariners;
- Positioning the VCS to contribute meaningfully to Canadian Armed Forces (CAF) Joint Operations ashore; and
- Ensuring the survivability of the VCS against current and evolving threats in an increasingly complex and changing battle space.
