Thread: How Fast Can Modern US Aircraft Carriers Really Go? | Forums

  1. #1
    I heard something about modern US Aircraft Carriers being able to do something like 50-80 knots at top speed, and that it is supposedly classified information.

    I can't remember where I heard this, but I distinctly remember hearing something about that, from whatever the source may have been.

    It just doesn't seem possbile to me, however.

    As well, I also heard about how the US, Canada, and Britain in WWII conducted experimenting with Arctic Aircraft Carriers, which were made entirely out of some kind of super packed ice, or something like that. The ice had some kind of special name, which I can't seem to recall.

    Apparently, those Ice Aircraft Carriers were never commissioned, for whatever reasons.

    Anybody else hear about any of this?

    I am not sure about the speed of our carriers, but I doubt they can go that fast. As far as I know even new age torpedos max out at like 80 knots.

    Here is a link to the ice carrier. It was a project in Britain and there was a good show on it on the History Channel awhile back.

    I'd guess around 35 knots top speed for a modern nuclear carrier. Aside from that, the escort vessels accompanying a carrier must be able to make at least the same maximum speed as the carrier. Carriers never sail alone, so there's no point in having the carrier go faster than her escorts.

    30+ knots, but real speeds are classified.

    With a conventional displacement hull, there is an upper speed limit at which a ship can travel, regardless of power. I don't have the formula at hand, but I'll see if I can find it - it is related to the vessel length but exactly how I'm not sure. There are ways of exceeding this limit slightly, but to get far beyond it you need a planing hull, which aircraft carriers clearly haven't got.

    Edit ----
    Using the formula from Wikipedia http://en.wikipedia.org/wiki/Hull_speed the limit would be around 44 knots, though more precise methods can now be used to determine this. 50 kts sounds just about plausible, but I'd think 80 kts was highly unlikely.

    Andy, this quote from the page you linked to states:

    The concept of hull speed is not used in modern naval architecture, where considerations of speed-length ratio and Froude number are considered more helpful. It is still used by amateurs in relation to traditional displacement hulls.

    All of your points are well taken, except that, any enemies of the USA should understand, that what I have posted here about the supposed reach of our military power, might actually be correct, at least somewhat, but that is up to those enemies to figure out, and that those enemies, or those who choose to create havoc in this world, should take into account, that they will be dealt with accordingly, should they choose to defy the true defenders of the free world.

    Amen.

    Otherwise, Mr. WhiteKnight77, your avatar is an A-10 Tank Killer, if I am not mistaken?

    So, what is that doing in a SHIII Forum?

    lol

    I took a screenie back when I was playing Jane's USAF. I have used it ever since I joined the Ubi forums.

    Most of the games I play are from Ubi and include GR, early Rainbow Six games, Splinter Cell (at least the first 2), the SH series along with iL2 and some LoMac,

    Is this better?

    Yeah, I saw that. It gives a ball-park figure though. As I said, it says 44 kt, modern design techniques can exceed this, but I'd be surprised if they could almost double it, which is why I said I thought 80 kts unlikely. There are other factors than hull shape that come into play anyway - notably propeller design if you are attempting to push a displacement hull to it's limits.

    I'm sure there are others about who know more on the subject than me, it just seemed a starting point for the question.

    In any case, as has been pointed out, there is little point in having a fast carrier if the escorts can't keep up.

    Hey WhiteKnight77, do you remember Jane's Fighters Anthology and USNF '97? I loved Jane's USAF, but unfortunately it doesn't like something about my more modern computers and crashes when loading anything after the main screen. Fighter's Anthology still runs though! (With an annoying buzz by the computer screen, but it runs, nonetheless.)

    Threadjack complete!
