For quite some time Windows has been gaining ground in running non-critical warship systems. But Microsoft are pushing their operating system to the 'next level'… using Windows to run the complete operations of a warship. I don't think Windows or the world is ready for such developments.
The Register tells the tale of a poor guy at BAE Systems who lost his job trying to stop the move to Windows for Warships. It's a very interesting story indeed. It's incredibly worrying that a so-called engineering company accepts using Windows for mission critical operations without an even-handed analysis of the alternatives.
