HMCS Victoria is currently undergoing her certification refit in Victoria.
Canadian submarines have a major refit every five years, which usually lasts just under two years. This refit ensures that they are safe to take to see, and fixes any major or minor safety-related defects. At the conclusion of this refit, she should have her design, building, layup and recomissioning issues fixed. She'll be fully capable of going to sea, and performing as a "clockwork mouse" for training Canadian and allied navies.
That's the good news. There's also bad news.
Despite the recent upgrade of the displays, the combat system will still be based around a UYK-20, which is about as powerful as an original IBM PC. The cutting edge of early 1980's technology. She'll be safe to drive around, but she won't exactly be a high-end combat unit.
I want a Virginia. Now THAT'S a boat with a high-end combat system.
