Canadian Patrol Submarine
procurement project for Canadian Navy
The Canadian Patrol Submarine Project (CPSP) is a procurement initiative that began in 2021 to replace the Victoria-class submarines of the Royal Canadian Navy (RCN). The project aims to procure up to 12 submarines to enable simultaneous patrols in the Atlantic, Pacific and Arctic oceans. In August 2025, the Canadian government shortlisted two suppliers, Thyssen-Krupp Marine Systems (Type 212CD) and Hanwha Ocean (KSS-III Batch-II), and will conduct in-depth engagements with both companies. On 6 July 2026, TKMS's Type 212CD was selected as the next submarine.
Background
Built for the Royal Navy between 1983 and 1993, the four Victoria-class submarines were purchased by Canada in 1998. The Victoria class will reach the end of their service lives in the mid- to late-2030s. The 2017 defence policy did not commit to a replacement for the submarines but did promise funds to modernize and continue operating the Victoria class.
The CPSP was established in 2021 to identify the RCN's requirements for a new submarine and make recommendations to the government. By 2023, the Ottawa Citizen reported that the RCN was pitching the purchase of up to 12 submarines at a cost of approximately $60 billion CAD.
In 2023, the following 15 draft high-level mandatory requirements were documented as part of initial exploratory work:
The platform shall be a submarine that can perform patrol and surveillance missions in Canada's maritime approaches and littoral waters.
The platform shall be conventionally powered (diesel-electric).

Why this record matters
A short description can identify a subject without explaining its stakes. For “Canadian Patrol Submarine”, the useful work is to connect “procurement project for Canadian Navy” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 22, 2026. The linked authority identifier is Q136469264. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2021, 2025, 2026 and 1983.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
