Model for new Canadian Navy?

This report in the Register talks about plans for the Royal Navy's newest design of destroyer to run Windows:

As The Register has noted in previous pieces on BAE's interesting Windows plans, this is no trivial matter. Whereas most previous naval deployments of Microsoft Windows worldwide have been overhyped, and have dealt largely with non mission-critical, non-lethal installations, AMS really is committing the Royal Navy to Windows-based command, control and combat management systems.

I found this a rather disturbing development, given Windows' deserved reputation for non-performance in critical environments. It also occurred to me that the Canadian Navy might follow suit, should they ever get enough money from the government to buy some new ships. I got really worried when I mentioned it to Jon, who said something like this:

It kind of makes sense, you know. Some wanker at the ministry fired up a Windows box, found the Minesweeper game and realized they could get rid of all those pesky real ships.
