Seaspan Vancouver Shipyards is building two Protecteur-class Joint Support Ships for the Royal Canadian Navy, integrating underway replenishment, helicopter support, medical facilities and limited sealift. The construction programme supports sustained naval task-group operations; delivery and operational acceptance are separate milestones.
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
First ship launched in December 2024; second structurally consolidated in April 2026. DND plans Protecteur delivery in June 2027 and Preserver in 2027/2028.
Contracted Canadian naval construction programme; operational trials follow delivery. The government schedule reflects first-of-class outfitting delays.
A technology readiness level is not established by the reviewed public sources.
No reviewed Mission area or released Defence need connection is currently published.
These records support this capability and its published Mission area and Defence need connections. A source count is not a count of independent confirmations.
