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


In March 2017, the government of Canada awarded Seaspanís Vancouver Shipyards with a contract to produce Queenston-class Joint Support Ships. 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 Queenston 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. The announced names of the new vessels are HMCS Queenston and HMCS Châteauguay.

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.
