The Royal Navy and BAE Systems plc were pleased as punch yesterday to announce that their implementation of Windows for Submarines™ is complete ahead of schedule. Windows boxes on Ethernet LANs are now in control of the UK’s nuclear-propelled and nuclear-armed warship fleet.

The programme is called Submarine Command System Next Generation (SMCS NG), and uses varying numbers of standard multifunction consoles with two LCD screens, hooked up on an internal Ethernet network installed on each sub. Initial reports as the programme developed suggested that the OS in question would be Windows 2000, but those who have worked on it have since informed the Reg that in fact it is mostly based on XP. “This is a fantastic achievement,” said Captain Pat O’Neill. “From speaking to operators and maintainers, I know how much they like SMCS NG. BAE Systems’ work is proof that we can get commercial off the shelf technology to sea quickly and support it affordably.”

Here on the Reg naval desk, we’d go relatively easy on submarine worries – even the Trident boats – as sub command LANs are by their nature very isolated and physically secure, and submarines almost never need to give their command systems autonomous firing authority. By contrast, however, an air-defence destroyer like the Type 45 – if it is to be much use – will fairly often have to give its collection of Windows boxes the ability to loose off a sheaf of Aster missiles without human authorisation. Shooting down the possible supersonic sea-skimmers of tomorrow will be even more impossible with the delays of having humans in the loop.

Just to add to the slight feeling of nerves, a destroyer LAN will need to be connected to other networks off the ship as a matter of routine, and physical access to a destroyer is hugely easier than to a sub as well.

So we aren’t really looking at Windows boxes triggering nuclear armageddon if something goes wrong here. But we just might, if things go wrong, be looking at a computer snag causing another USS Vincennes airliner shootdown disaster in coming years. Or, of course, at British sailors of the future staring helplessly at what would shortly be literally a blue screen of death, as the shipkillers bored in without response.

Fire when ready!
