Joint Support Ships

The Mission

The Joint Support Ships currently being constructed for the Royal Canadian Navy will be purpose-built, multi-role vessels that will provide an important auxiliary function to the Royal Canadian Navy. One of the most important aspects of these vessels is their ability to replenish naval task groups with marine fuel and other provisions while at sea. This allows the Royal Canadian Navy to operate away from port for longer periods of time. In addition to replenishment at sea, the vessels will support training and naval manoeuvres and humanitarian operations, ensuring Canada’s continued safety and security at home and abroad.

Joint Support Ships facilitate collaboration with allied navies by enabling the Royal Canadian Navy to operate away from port for longer periods of time.

Seaspan Shipyards has worked with the Royal Canadian Navy to ensure these ships fully meet Canada’s needs and contain modern systems and equipment.

Canada’s auxiliary ships are being built based on a successful design that was used to construct Germany’s replenishment vessels.

Each month we capture and share progress photos of the vessels currently being constructed at Seaspan Shipyards. These vessels include three Offshore Fisheries Science Vessels for the Canadian Coast Guard and the first of two Joint Support Ships for the Royal Canadian Navy.
