Windows for Warships
The Type 45 destroyers now being launched will 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.
And here’s a related story about a software bug in the F-22 Raptor stealth fighter. It seems that the computer systems had problems flying West across the International Date Line. No word as to what operating system the computers were running.
EDITED TO ADD (2/27): Here’s a related article from 1998, involving Windows NT and the USS Yorktown.
