So, we know that a Canadian submarine replacement program has stood up or is about to standup. There is lots of speculation of what Canada will eventually choose. While there is much talk about going with a proven design there are also many who have suggested the RCN going with our own modern design. There are risks such as what AUS has faced with the Collins Class and now with its replacement. I am going to suggest something very controversial and radical. Have BAE Submarine Solutions build an updated version of the UPHOLDER design with the latest in propulsion technology, no AIP and leverage the latest in lithium ion battery technology to increase range and endurance. Even at its worst the Victoria Class are good boats, the fact that the boats were left to their own devices for two years with no maintenance or storage protocols caused all the initial problems that continue to dog us today. The VICTORIA with conventional wet batteries had a range of 12000km and 30 days (about 4 and a half weeks) endurance, new lithium-ion batteries, motors etc. would no doubt extend this. The size and SSK shape of the UPHOLDER design was fine, you could easily enlarge it if needed. No need to Canadianize it as it will already be built with that in mind. Arm it with the MARK 48, Harpoons or NSM and equip it with the latest in sonar technology that the Victoria's have now. Take advance of greater automation to reduce crew sizes, improved crew comfort and resulting build 6 to 8 hulls and purchase enough spares to take the boats to the next 40 years. You could even call it the Improved Victoria Class.
