Royal Navy goes with 'Windows for Subs'

Bucking the open-source trend, the British Royal Navy has developed a modified version of Microsoft Windows XP and has begun installing it on its fleet of nuclear submarines.

The new Submarine Command System Next Generation (SMCS NG) employs standard multifunction consoles with double LCD screens, linked with "commercial grade" cables and software to internal Ethernet local area networks (LANs) aboard each sub.

Ever thrifty, the spit-and-baling-wire Brits went with Windows in part because it was cheaper to maintain. The use of commercial off-the-shelf technology is expected to save the U.K. taxpayers up to $32 million over the next 10 years -- or about one-thousandth of the operating costs of a Vanguard class submarine, according to one estimate.

"This is a fantastic achievement," Capt. Pat O'Neill said in a press release. "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."

The Royal Navy, working with defense contractor BAE Systems, installed an entire Windows SMCS NG LAN on the HMS Vigilant in a mere 18 days, according to BAE.

Training time is faster as well. Given that Windows runs on approximately 85 percent of the world's PCs, there is a good chance sailors are familiar with it. However, so are hackers -- both the amateur and the cyber warfare pro variety. Not a problem, according to BAE, since all hack-prone elements of Windows "were tended to during the modification."

Meanwhile the Yanks, citing better security and more versions to choose from, continue to go all-in with Linux to boot up both warships and the long awaited Future Combat Systems. But then, they still drive on the wrong side of the road.

Not a debate on what OS they should/could/must/might be using. I just have one question, why XP instead of Vista? Yes, this is not really a serious question, I was just wondering what made them choose. This is not a XP vs Vista bash, I am thinking there must be a technology related or cost reason maybe?

Not "LOL VISTA IS BLOAT, XP SLEEPS WITH MOM SO IT ROOLS".

"since all hack-prone elements of Windows "were tended to during the modification."" I also wonder how this will play out. No software is hack-proof.

I agree, with all the hacking they did to get Windows XP secure, they could have saved themselves some time and trouble by taking advantage of Vista's own improved security architecture such as UAC (which is actually worth being an annoying in an environment like that), ASRL (Address Space Randomization Layer) - which basically jumbles up code on boot up of the system fooling malware and any type of malicious code, would be great for their mission critical systems. Device Driver Signing in 64 bit Vista which is excellent and guarantees that hardware is designed for the OS without the guarantee of it bringing down the system, no kernel mode drivers, kernel patch protection which would prevent hackers from easily picking the OS's brain, DEP in addition to Windows Defender and Vista's Firewall with Advanced Security and richer Group Policy Editor with support for blocking devices like unauthorized USB thumb drives. Seriously, why did they choose Windows XP?

If you look at the time it takes to go through any military procurement, which isn't much shorter in the UK than it is in the States, and then the time required to do all the security modifications and check them out, you quickly work back to a start date where Vista wouldn't have been an option.

Software with no network connection sitting onboard a nuclear submarine with armed guards is pretty hack proof. If someone manages to get to that computer then the software on it is the least of your concerns.


XP was chosen because of the development cycle of the software. Military hardware/software have a very slow development cycle compared to civilian. Basically if they used Vista the testing process would take so long that we would be looking at Windows 8 before it was finished. Despite rabid fanboy opinion the choice of XP has nothing to do with the merits of Vista. If it did then you could apply the same logic to why OSX and other *nix OSs weren't chosen.

Nothing could have really been gained by the additional Vista security features in this scenario. Again.. no public network, physically secured environment etc..

Portions of the American Aegis system run on NT 4.0 kernels with Java. The thing is bloated, crappy, and incredibly slow but it does exactly what it is supposed to and does so reliably. The US military was also using DOS and Kermit (if you even remember what that was) up through the Windows 98 days.

smilin:) : is there a fact that says there is no network connection to the outside world? maybe even back to base/headquarters via satellite or a RJ45 port on one of the undersea cables that keep getting cut? (last part is a joke, of course).

I do agree, XP is smart in terms of tried and true due to its age.

Putting windows on a submarine is about as smart as open a window in space....remember the summer of 2008 when a US Astronaut opened a window the US shuttle...he transferred a virus from his thumb drive...and infected the computer. Opening a window on a submarine could result in a flood of problems... can you say ID-10-T error.

What, no i-Sub?
by jgo10 December 29, 2008 6:51 AM PST
How long has this been under development, that probably will answer the way XP vs. Vista debate. These projects usually take years to develope.

Even so....... you would have thought that they would have been working side-by-side Microsoft on improvements to the operating system that both military and civilians would be able to use.
by ballmerisanape December 29, 2008 6:57 AM PST
XP? Are they that confident that they were able to do something that microsoft could not? What happens when the system bloats itself after a year....wipe and reinstall? Hope they reboot before before each battle ;)

I would make it so you have to submit a request, in writing, to install a program. And have the only people that has permissions to install programs back on land, so by the time there's a chance to install, the person either forgets about it or doesn't care any more because he can use his own computer. You must keep users and their bloatware oceans apart (pun intended).

My god I can see the next Bond screenplay now: 13 year olds from LA seize control of the British Fleet from their xBOX. AND the MAC/PC AD: PC is dressed in a British navel uniform and being controlled by a kid off stage with an xBOX. I bet even the African Pirates aren't use Windows.

this sounds rather dangerous. since windows isnt open source any code changes the navy makes may make the OS unstable. they might need to learn it the hard way...

"My god I can see the next Bond screenplay now: 13 year olds from LA seize control of the British Fleet from their xBOX."

Of course the real villain pulling their strings will be revealed to be none other than (wait for it ...) Bill Gates himself. It's the classic story of a bajillionaire megalomaniac seeking to destroy every city on the globe with a current or planned Apple Store who simply couldn't afford the time necessary to construct his own fleet of submarines and acquire nuclear missiles. Instead, he hijacks what he needs from an unsuspecting British Government after convincing them to install a modified version of XP which allows him to control their fleet from his brown Zune. Gates is ultimately foiled when Bond allows himself to be captured by Gates so he can squirt missile tracking coordinates into Gates' Zune, turning Gates into the first target.

Anybody watch Battlestar Galactica? These subs are going to have to plug in to update at sometime and that is when they will get hacked. Subs do communicate with the outside world as does every freaking ship. You know why you develop your own software for war machines because they contain equipment that no one should know how to use unles they are well aware of proper uses. Shorter training time is stupid if you ask me as now anyone can hijack a sub and start shooting nukes. All the enemy has to do now is write a virus for windows as if the developers can't maintain an open source distro there is no way they can cope with the numerous faults in windows.

Imagine a bluescreen of death during a practice session, or at the wrong time when they are trying to cancel an attack command.

Also doesn't the UK have disagreements with M$ being a monopoly and some other stuff. I mean now they are allowing the monopoly to start controlling their subs. I bet some high ranking admirals are making some pretty good cash from this transaction.

As to the reason why windows XP was chosen over Vista, its because Vista is not that great and it is still relatively new. I laugh when you say that anything in windows is better than an open source distro. Yes you can screw things up in an open source solution, but windows has flaws that are unrecoverable from unless you pay M$ a bunch of money instead of hiring your own staff that are subjugated to confidentiality agreements.

Just think about this why would you install software in government systems that are made from a company that isn't native to your soil and on your side in a potential conflict. Heck to make matters worse you just gave access of all your subs to a company so they can nuke their competition or did u not read the fine printing in the license agreement.

There are no 'unrecoverable' flaws in Windows. Even when my system has been so ****** up to need a complete re-install, the complete re-install has ALWAYS, repeat, ALWAYS fixed it.
by tm_anon December 29, 2008 10:16 AM PST
@Lerianis

'Unrecoverable' in this case means having to do a complete reinstall just to get it running. I'm one of the lucky ones. I used XP for years and never saw a bsod. However, I have had viruses, I have had trojans, I have to run antivirus, antimalware and system cleaner software just to keep it running smoothly. The danger isn't so much in the viruses, it's in how quickly the system needs a defrag. Imagine someone makes a single mistake, clicks the wrong box or the wrong button, arming a nuclear warhead and launching it, but luckily there's a countdown. You think there's enough time to stop the launch by running the failsafe program, so you double click. Now it just has to load up in time to stop the launch and you're done. What you don't know is that nobody has run a defrag in the past year and now the system is so messed up it takes twice as long to load the program. Two seconds after the nukes are launched, the program loads, but there's no way to turn them off remotely because that would be a backdoor for hackers. Millions of people just died because Windows needed a defrag.

Lerianis, I'd like to see you reinstall Windows while your sub is under attack. No pressure there, eh? This would give a whole new meaning to "Blue Screen Of Death"....

If I had to trust my life to an operating system, Windows (in any form) would be far down the list.

A pool for subs. LOL
by Dalkorian December 29, 2008 10:46 AM PST
Thank whatever deity you believe in that our own military is smarter than this. I'm now starting to work on a "screen door" for them, which will prevent predatory sharks from getting inside the sub when the windows are invariably left open.

Or did the comment "all hack-prone elements of Windows were tended to during the modification" mean they redesigned the OS from the ground up, removing the plethora of security issues woven into the fabric of the OS?

So this is a "Security Enhanced" version of XP. Isn't there a Security Enhanced version of Linux already. I would assume BAE would have had to get prior authorization from Microsoft to do what they did to the OS. Being that it was XP I would assume they would have had to make Kernel modifications to get their desired output.

And then there were...THREE: Windows XP for the "British", Linux for the "America"; and OS/2 Warp for the "Russians" and Commander_Spock and Crew! Told ya all a long time ago that Code-Base OS/2 (Windows) will always be Code-Base OS/2 (Windows)!

Now, let's see how soon "THE CONCORDE" flies COMMERCIALLY - again!

Windows XP on subs? Cue "Nearer My God to Thee."

Ironic that a ship where you avoid leaving holes open will run on Windows. Lordy I hope they don't have any nukes being handled with it! :)

well, one good thing, the construction industry should thrive, what with
the resulting renewed interest in Bomb shelters.

It's scary enough trusting Windows with my files, but nuclear submarines?
Thats bloody scary old chap.

Thats bloody scary old chap....". Better this, it is time for Commander_Spock and Crew and the makers of "THE CONCORDE" to restart the commercial business operations for getting "rich" interested persons as "fast"; and, as "far" away as possible if they feel that unsafe. The simple question: "Money" or "'Fly Away On The Concorde For For Your Life"? Ah Ha! (Smile)!

"But then, they still drive on the wrong side of the road."

"Though originally most traffic drove on the left worldwide, today about 34% of the world's people live in left-traffic countries and 66% in right-traffic countries. About 28% of the world's total road distance carries traffic on the left, and 72% on the right."
