Well the Big E had what, 4 reactors and 6 or 8 screws? I bet she could do in excess of 45.

Well it's not like they have to worry about fuel.
Although I'd think the top speed would be limited more by the speed of the escort ships and their fuel endurance. No point in getting the Carrier in the hot zone without it's protection. |

Enterprise is a dinosaur in terms of propulsion design (8 separate reactors is a bit ridiculous) but pretty much any displacement hull has a maximum hull speed that's a function of its dimensions and design, and more power won't matter. Generally longer boats (at the water line) have higher hull speeds. This does not apply to boats that can plane, but big warships can't anyway. |

A Nimitz class carrier has a waterline length of 1040ft, plug that into the hull speed formula and you get the result that the hull can go 43.21 knots (49.73 mph) without needing to plane (assuming sufficient engine power).

With enough power you can exceed hull speed without going on plane. I've exceeded hull speed on my sailboat a few times at max throttle with a oversize engine. Not by much and the power requirements are a bit extreme. I'd say 45 knots is going to be max. |

Not by much and the power requirements are a bit extreme. I'd say 45 knots is going to be max. Based on my personal experience, and seeing the shafts turning from Main Control, on a "cruiser", fresh out of the yards, bottom clean, optimally weighted (bow slightly up), with a bulbous bow sonar dome. We made indicated turns for around 43 kts. Seeing the steam needed to make those last few knots. Realizing that carriers are not going to have really clean hulls, that no sane engineer is going to push things like they do in the movies or TV, "Scotty, we need more speed.", yes the reactors and steam generation side of the plant has a theorectically ridiculously high capacity. The rest of the systems, feedwater storage and injection, piping and turbine flow restrictions, condensation side (taking turbine exhaust and converting it back to feedwater for transfer to feed tanks) have definite physical limits. You can only stuff so much steam at high system pressures through piping of fixed diameters, the only way to get more power to the turbines and faster shaft speeds is to go to higher pressure and/or higher pressures. Too high pressure or temperature means a failure at some point. And even a small point failure with steam at those conditions means a pretty rapid deterioration to a really bad system casualty. I'd hazard a guess that above two posters are pretty damned close to actuality. (well more than just a casual guess) |

He never said why or where they were headed, but apparently the carrier wasn't concerned with the escort being able to keep up. |

I obviously cant say exactly what i have seen top speed wise but the "+" in "35+ knots" is a very small one. there are many additional limits besides what it is theoretically possible to hit, and the equipment will limit you before available power. I have been on watch for sustained hgh speed runs including top speed runs on sea trials both on the NIMITZ, where I am sitting right now, and on the GW. -Mike |

I can tell you that riding on one going full tilt, that whole ship is shaking and you know you are really moving. very strange feeling. I would guess 40 - 45 knots. Could they outrun the Belknaps? (I was on a Belknap cruiser) maybe by a few knots, maybe "knot". That was in the old days when some of the escorts had 1200 pound steam plants. The Belknaps probably had the optimum hull configuration with their bulbous bow, They Leahy's maybe had a little more horsepower to weight, but the plain bow configuration led to more pitching at max speed. Now with the escorts mostly gas turbine powered, probably they can, but not by a whole lot of knots. They can definitely outlast the escorts. Escorts have limited fuel and range compared to the carriers. The other ships in the battle group, oilers, unrep ships etc., no question they can run away from them. Also your ASW challenge gets a lot worse. A CVBG moving at speed makes a lot of noise, and finding quiet submarines at a safe range actively or passively for the close in escorts is almost impossible. |
