Swedish Carbon-Fiber Stealth Ship Runs NT 526

tiled_rainbows writes "The Guardian has an article today about the Swedish navy's new stealth warship, which they claim is the largest carbon-fiber vessel ever built. Slashdotters will be interested to learn that the ship runs Windows NT. The article says 'While the point-and-click system is popular with conscripts, the ship was fitted with a wooden ship's wheel at the insistence of senior officers. If Windows goes down, they will still be able to steer.' Which raises the question: where can I get a USB-compatible wooden ship's wheel for my computer?"

          The issue was that they divided by 0, and the resultant crash bubbled up and crashed the os on a network controller, in turn taking a whole group of systems down with it. While the proprietary systems triggered the crash, it should not have gone so far, so the OS does bear some responsibility.

      I know it's a joke, so yes, except Sweden doesn't have "nukes".

      Actually (I'm Swedish) we don't have much of an army, airforce, or navy, at all anymore..

      Not that I personally agree to spending the kind of money you do in the US, but the military situation is pretty pathetic in Sweden (although it's been a few hundred years since we were a military power by any standard).

      We can't defend our borders at all, and we probably can't wage an effective (defensive/guerilla) war on Swedish soil either (no militia to speak of, laws against owning weapons other than for hunting, etc.).

      The cuts in the military budget has been brutal, to the point I was kind of amazed that they've been able to develop this stealth vessel at all (with what money - the entire navy budget?!?).

      Without much debate, politicians have been working overtime to convert (reduce) our own military to a few special units (like this stealth corvette thing) - perhaps to be used in some large EU military force.. (Not that I know enough about it to say whether 'tis a 'Good Thing', but I've always considered self-reliance to be important, so.. I guess I think it sucks bigtime.)

        Part of it is the relative quiet in that part of the world. It's one of the reasons that, since 1991, there has been political pressure in the US to move forces from Germany to somewhere else where they'd be more useful. Any power there willing to try to build up forces for offensive operations would likely be unable to hide significant portions of it, and would thus provide time and reason for surrounding nations to match a buildup. Everyone knows it, and Europe is mostly united in its desire to aquire more money instead of more bullets, so there's little reason for anyone to go on the offensive.

        Barring a revival of the Russian bear, there's really not a lot to worry about, and besides, you've got the Finns there to sacrifice themselves for your safety (as has happened on several occasions in the past, IIRC). :)

    I'm not a materials scientist, but I would imagine that carbon fibre can burn. A huge advantage of steel is that it may weaken under heat stress, but it will never contribute to a fire, which is one of the gravest threats to a warship in combat.

    The British learned this lesson the hard way in the Falklands. In that case the new building material was aluminum, which can actually burn when it gets hot enough. This contributed to the loss of several ships which suffered massive fires after being hit by Argentinian aircraft. As a result, not only in the UK but in navies around the world, new naval ships are built entirely out of steel.

      As someone who worked in a carbon fiber development lab in the eighties, I will agree that carbon fiber can burn.

      But as the MSDS for carbon fiber points out:

      Flash Point/Method: Not known, but very high!
      Auto-Ignition Temperature: Not determined
      Flammable Limits: Lower: Not applicable

      Building major combattants out of carbon fiber & epoxy may well expose these ships to fire hasards (however this will be more related to the epoxy that binds the fibers than the carbon fibers themselves. Carbon fibers burn relatively cleanly, epoxies, on the other hand put out fumes that will incapacitate & blind crewmembers that are trying to control the damage). Having carbon structural members burn through & fail is of little import if everyone is already dead due to the smoke.

      Your example of HMS Sheffield is in any case incorrect and is covered in the sci.military.navy FAQ: [hazegray.org]

      There are many misconceptions and incorrect stories regarding the use of aluminum in warship construction.

      One common story is that HMS Sheffield, a destroyer sunk during the 1982 Falkland War, was lost because her alleged aluminum superstructure made her more vulnerable to damage. This story is completely untrue, because Sheffield's superstructure was not aluminum. Like all ships of her class, her hull and superstructure were entirely steel. Aluminum played no role in her loss.

      Two Royal Navy warships lost during the Falklands War did have aluminum superstructures, and their loss is incorrectly attributed to this feature. Ardent was hit by seven 500- and 1000-pound bombs, plus at least two more bombs which failed to detonate, and sank some six hours after the attack. Any warship of her size, regardless of aluminum or steel construction, would likely be sunk by this many bombs, so aluminum cannot be blamed here. Antelope, another aluminum-superstructure ship, was struck by two bombs, which lodged in the ship but failed to explode. Later, while one of the bombs was being defused, it exploded, blowing a major hole in the hull and starting a large fire. The fire eventually reached the magazines, causing these to explode. Again, an aluminum superstructure appears to have little connection to the ship's loss, which was caused by the explosion of the bomb and the magazines.

      A related story claims the US Navy and Royal Navy abanonded aluminum superstructures, in favor of steel, as a result of the Falklands war. Since aluminum superstructures played little or no role in the Falkands losses, this story is obviously untrue. The Royal Navy's switch to steel appears to be a result of a 1977 fire in the frigate Amazon. In the US Navy, the switch from aluminum to steel superstructures was a result of the 1975 collision between the carrier John F. Kennedy and the cruiser Belknap. The collision caused major fires aboard the cruiser, and her aluminum superstructure essentially melted; she was reduced to a badly burnt hulk. This incident lead to a decision to adopt steel superstructures in the next new warship class, the Arleigh Burke (DDG 51) class destroyers. This decision had been made prior to the Falkands War.

    During combat it becomes necessary to increase your rate of fire to ensure the destruction of enemy vessels. Microsoft does not endorse the use of this software on fishing boats, pleasure craft, or walruses.

    From the Control Panel select "Forward Cannon." Right click on the cannon and select "Properties." From the "Firing Rate" tab make sure the "Fire at will" option, and click the apply button. If the ship does not begin firing type "Regedit" at the command prompt. Under "HKEY_CLASSES_LOCAL_MACHINE" search for "Fire Control" and make sure the is a "Fire Control" entry in the registry. If necessary, load the Forward Cannon 1.3 install CD and double click the fcannon.reg file.

    Once the cannon is installed, you may choose to test-fire a round. You will be prompted with a dialog asking if the target was hit. Clicking on No will take you to a web page with possible reasons (non of which will actually apply) as to why the target was missed. Some targets are not compatible with Windows and cannot be hit with the forward Gun.

    From the article:

    In other words, its great weight makes it _more_ likely to avoid attacks -- perhaps by escaping downhill.

    The good: A lightweight, stealth ship. I'd love to have one. I have no need for one, but it would be cool. (I'd rather have a lightweight, stealth car, esp. if it came with a retractable 57mm cannon!) Do we have any idea how well CF will really hold up in this case, though? Both in long term maneuvers and under attack by enemy aircraft? What about barnacles? OK, the good we don't know for sure.

    The bad: Let's see, didn't the US Navy already experience a problem with an NT4-based ship being dead in the water? And a dead ship can't maneuver. If there are other ships around, that's not a good time to be invisible. (Captain of aircraft carrier: "What was that crunchy sound?")

    The ugly (editing): "And if it is detected, the Visby should be quick enough to escape as it is only half as light as a conventional corvette." Presumably they meant half as heavy!

    It might be the one pointed out by the Guinness book cited in the article, hence the various James Bond jokes as well as the Taiwan interest ; indeed, the french stealth frigate appears at the beginning of the last (or before-last) 007 movie, and it was sold to Taiwan by Thomoson , giving rise to a huge financial crisis. The frigate is however not made of carbon.

    I hope the frigate has a lower radar signature than a 1970s Volvo...

    People have been building boats from fibreglass for a long time. There is no difference between working with CF and working with fibreglass - it's just that CF is stronger and more expensive (and thus more difficult to cut).

    Also, if you use the technique the Sweedes used (sandwich expandable foam between two CF layers), the hull is alot more buoyant than a steel hull - which means you can change the shape (within reason) to a more stealthy version.

    Modification would be a bitch though! If you want to weld a new bracket to a steel hull it takes 5min from the inside or a few hours to do externally. If you try the same thing on a CF hull, it takes a few hours (12?) for the CF resin to go off. Forget trying to modify the exterior hull without a drydock. Also, in the event of wartime damage repairs you can weld a new plate over the hull and have it watertight and you are good to go. No chance with CF - it needs a completely dry environment (assuming you even have enough raw CF & resin in the first place - you can't just reuse old sections)

      Emergency repair isn't an impossible situation to handle. There are plenty of epoxy resin systems that have short (15min) cure times. While I can't imagine that they'd have time to properly vacuum bag it in an emergency, it's not the end of the world if a patch is a bit resin-rich. A simpler and more likly alternative is the use of a room temprature curing pre-preg patch. While it would require refrigerated storage, it's a simple peel and stick solution. These are commonly used in auto racing marketed under the "RhinoPatch" brand name. they gel in 30 seconds and cure in under a minute.

    I don't know anything about this, which is why I ask...

    I RTFA and it mentions being less visible to radar, infrared, etc but says nothing about sonar detection. Isn't sonar a big way of tracking warships? Is this still going to be vulnerable to that?

    According to what little info is avialable from Janes [janes.com] The ship is one of two which were initially ordered in 1995. Military procurement being what it is, no matter where you go, the ships were probably designed with NT in mind, circa '95. However, I doubt NT will last longer than the first refit or post-sea trials.

    The US and UK navies are both experimenting with a number of computer-control options ranging from MS solutions, to various *nixen. Of course there is the now aporcyphal story [seclists.org] of the NT crash that put the USS Yorktown dead in the water. Short answer, it may have been built on the NT platform, but lots of replacement systems exist now and I doubt NT will survive long enough for the ship to enter the active list.

    From the article:
    And if it is detected, the Visby should be quick enough to escape as it is only half as light as a conventional corvette.

    So.... is it twice as heavy as a conventional corvette?

    Apparently the Swedes did not learn from the US Navy's experience of using NT to run the ship. Not a good thing to be dead in the water because a computer crashed. IIRC, in Microsoft's EULA it specifically says not for use in critical systems.

    It makes me sick to see how often fools, imbeciles and idiots attempt to use an OS which has no real-time capability whatsoever to do real-time work.

    NT is known for freezing for periods of up to 10 seconds (maybe more?) at random intervals, quite probably while it defrags the mess it has got its memory into. The same problem happens with Win2000 and I have also seen longish freezes in XP. Controlling a ship, or anything lese for that matter, needs hard real time.

    Not only that, in most countries, evidently not Sweden, the software would have to be capable of validation and verification to a suitable standard, that can of course only be accomplished if you have source. The currently fashionable standard assigns criticality levels Sil1 to SIL4, now NT can't even meet SIL1 (SIL4 is the highest, mandatory in life-threatening situations). Previously, lots of people followed the aircraft industry in assigning levels 1,2,3,4 or A,B,C and D (in these cases 1 or A was required in potentially life-threatening cases). An extra level, Z, was introduced, guess why?

    I once upon a time thought that the Swedes were generally competent, however with the JAS39 Grippen, and now this, I think that their defence industry has become a complete joke. I could tell you about their SAAB civil aircraft, fortunately they are out of production now.....

    7. note on java support. the software product may contain support for programs written in java. java technology is not fault tolerant and is not designed, manufactured, or intended for use or resale as on-line control equipment in hazardous environments requiring fail-safe performance, such
    as in the operation of nuclear facilities, aircraft navigation or communication systems, air traffic control, direct life support machines, or weapons systems, in which the failure of java technology could lead directly to death, personal injury, or severe physical or environmental damage.

    Interesting that they pawn this all off on Java and not anything having to do with Microsoft.

    Carbon fiber is indeed really really strong, but it's a serious bitch to repair. A shell that hit the ship would make a nice big hole (carbon fiber is pretty brittle -- I wonder if they've got a kevlar shell outside of it, or would that mess with the radar signature?) of splintery mess.

    I guess rather than welding it they'd be using epoxy to repair? At least that's what we do with R/C planes that use carbon fiber (well, usually you replace the carbon fiber completely when it breaks -- not an option for a ship made of it.)

      Maybe they use individual plates that can be replaced one at a time.

      Emergency repairs would be a bitch, though.

    NT is one of the only operating systems the FDA approves for class 2 (and higher, I think) medical devices. It's funny to say Windows NT bombs out all the time, but that's mostly because of driver issues. The fact remains that for embedded/turnkey applications, NT is about as stable an OS as you can get. It got that job by replacing OS/2 (in ATM software, etc) not by replacing a UNIX platform.

    Mod me down if you want, but you know it'd be abusive, and this is totally on-topic.
