When CVN-71 went balls to the wall, it was a bit more than 30 knots and anyone listening could here us on the other side of whatever pond we were sailing on at that particular moment.

I've seen 688 Fast Attacks going at least 30 kts on the surface... Used to live outside of Groton, CT and we'd meet the fast attacks as they came in off patrols - lots of fun riding the wake of one of those bad boys.

Never saw anyone ride the wake of TR (except dolphins and they normally rode the bow wave)...might have made quite the picture.

Yeah, you couldn't get too close because the security boats would get pissed... But you could still catch some nice air off the wake astern of the boats. Granted this was back in the late 1980s before all the terror attacks increased security. I bet you couldn't get within half a mile of one now.

multi millions of dollars, new technology, best damn boat to ever grace the seas, etc

but all it takes is one missle, torpedo or mine and all that bling sits on the bottom..

Not exactly "now", the Soviet Victor was faster than 30 knots and that was in the Sixties.

I heard a Victor could outrun a torpedo, dont know if its true or not, but thats pretty spiff if so.

No Victor could do 30 knots. And no way would it outrun a Mk-46, let alone a Mk-48 or Mk-50 torp. The Victor I was the fastest (and the noisiest) of the 3 Victor classes (VI, VII, VIII). Having had the opportunity to chase several of them in the P-3 flying days using SSQ-63 DICASS sonobuoys, I've seen them use every tactic in the book from evasive maneuvering to flank speed runs trying to break contact (funny what a submarine will do when it hears short-scale pinging from an active sonobuoy close aboard). They act like it's an attack mode [:D] or something!

The first Soviet sub to break 30 knots was the Alfa. The Akula, while not as fast as the LAs, can exceed 30 knots. The Sierra is slower than the Akula. The Severodvinsk SSN was after I retired so I never had a chance to fly on it.

IIRC another big factor in a ship's speed is the length of it's hull. Don't ask me why because I wouldn't have a clue.[:(]

[Raverdave]

*sniff* All this talk about Harpoons and modern ships is making me sad for the fact that Harpoon 4 was cancelled. *Sob*

[kellyc]

Well Harpoon3 isn't bad and last I heard they're still working on MP (I was a beta tester at the beginning of it). Then of course there is HC2002 which is a new and improved Classics version (another thing I beta tested.)

I think I burned out on modern naval war cuz I haven't tinkered with any of the various harpoons in nearly a year. Sad but that happens from time to time, maybe one day I'll get sucked back into it.

I was kinda hoping that Matrix would take up the banner and publish H4, but that looks like it is not going to happen.[:(]

If they can do 30 kts on the surface, they must be able to do close to 40 kts underwater (subs can go faster underwater as they have no "bow-wave" phenomenon to fight).

The "bow-wave" phenomenon is also why ships with longer hulls can go faster. A surface ship can only go as fast as the speed the produces a bow wave the length of the hull (unless it planes out of water like a speed boat or hydrofoil, in which case it has no bow wave to speak of.)

Thus for say, two ships with the same amount of power - one 150 feet long, the other 200 feet long: the shorter ship is going to produce a "bow wave" long before the 200 foot vessel. The extra power goes into deepening the bow wave for the shorter vessel, in effect pulling the ship deeper into the water and causing increased resistance - and no increase in speed once the "bow-wave" reaches the length of the ship.

The bow-wave is actually not just the "bone-in-the-teeth" but the curve of the wave along the length of the hull. If you see a smooth curve that starts at the bow, and ends at the stern, the ship has about maxed out on speed.
