Proposed ships of the Royal Canadian Navy

The General Purpose Frigate, or GPF, was a procurement project for the Royal Canadian Navy during the Cold War. The class was also known as the Tribal-class frigate. Intended as a replacement for the Second World War-era destroyers in service at the time, the frigate design was developed for the Progressive Conservative Diefenbaker government in the late 1950s as part of the general fleet renewal program. The GPF program was cancelled under the Liberal Pearson government as part of their plan to reshape the Canadian Armed Forces. Following the cancellation, a modified version of the design was used for the Iroquois-class destroyers.

The Protecteur class (formerly known as the Queenston class) of naval auxiliaries for the Royal Canadian Navy (RCN) began as the Joint Support Ship Project, a Government of Canada procurement project for the RCN that is part of the National Shipbuilding Procurement Strategy. It will see the RCN acquire two multi-role vessels to replace the earlier Protecteur-class auxiliary oiler replenishment vessels. It is expected that the first of the two ships will be delivered and commissioned into the RCN in late 2025 and the second delivered by 2026.

Harry DeWolf-class offshore patrol vessels are warships of the Royal Canadian Navy (RCN) built within the Government of Canada Arctic and Offshore Patrol Ship (AOPS) procurement project, part of the National Shipbuilding Strategy. In July 2007 the federal government announced plans for acquiring six to eight icebreaking warships for the RCN.

The River-class destroyer, formerly the Canadian Surface Combatant (CSC), and Single Class Surface Combatant Project is the procurement project that will replace the Iroquois and Halifax-class warships with up to 15 new ships beginning in the early 2030s as part of the National Shipbuilding Procurement Strategy.
