The Type 45 destroyers now being launchedwill run Windows for Warships: and that's not all. The attack submarine Torbay has been retrofitted with Microsoft-based command systems, and as time goes by the rest of the British submarine fleet will get the same treatment, including the Vanguard class (V class). The V boats carry the UK's nuclear weapons and are armed with Trident ICBMs, tipped with multiple H-bomb warheads.
