This document is intended to collect information about the electronics fit aboard the new Protecteur class Joint Support Ships as it becomes available.


On September 12, 2017  the Royal Canadian Navy (RCN) announced that the Joint Support Ships (JSS), its future Auxiliary, Oiler and Replenishment (AOR) vessels, will be known as Protecteur-class ships instead of the Queenston class.

The renaming of the JSS to Protecteur and Preserver by the RCN recognizes the distinguished and remarkable service provided by its past Protecteur-class ships that have carried these names. The renaming perpetuates the Battle Honours awarded to the forbearers of these ships and allows the future ships to add their own Battle Honours to the Preserver and Protecteur legacy.

In March 2017, the government of Canada awarded Seaspanís Vancouver Shipyards with a contract to produce Protecteur class Joint Support Ships as they were called at that time. The project aims to replace the three former Auxiliary Oiler Replenishment vessels which are currently all paid off.  The program to build two ships has been budgeted for $1.7 billion.

Under the contract, Seaspan will provide production and engineering services to support the program. The  two Protecteur class vessels will be part of  its National Shipbuilding Strategy, but consideration is being given to building a third vessel. The government expects the first vessel to be delivered by 2021 and the second by 2022.

Seaspan received the production order after completing an initial design review for the ships based on designs by ThyssenKrupp Marine Systems Canada. The company was previously contracted in December 2015 to supply equipment, propulsion systems, and generators to finalize the design. Once completed, the Joint Support Ships will be used to provide limited sealift capabilities, offshore operations support, and core replenishment duties.
