Traildust, that is great news! I hope I'm still around to see it commissioned. My opinion of Mabus moved up.............a little bit. :-))

I was told to go to ft Pickens campground, where I could see her. Then I was told no on board tours,. That's just the worst news I could hear. Was told that there is still fuel on board and we can never see her. Is this true. Really too bad

CVA(N)-65 Wasn't attached to the CAG, but landed on her deck off the P.I. in 65. Was the best boat in WestPac at the time. Longest and only carrier to ever have four rudders. I 'd tell what her top speed was, but it may still be classified

Our destroyer was maxed out at 28 knots turbines WO and 1200# boilers pulled down to 980# and the BIG E went by us like a '68 GTO racing a Rambler .......

Published is 33.6 KN

Hull speed formula ------43+ KN
(1.34 X sqrt of hull at waterline)

Your a little low OB, sounds better in MPH..Lol. Lets just say nothing in the group can keep up. The old man did a speed run and the knee knockers where buzzing and passage ways hummin. During the turn deck went to 20 degree angle. There is a published photo of her turn out there somewhere. As 1st nuke carrier with eight reactors, she's to be broken up and used to build the next Big E.

Doesn't matter that she had 8 reactors still only had 4 main shafts which are rated at 280K SP each. Same as the old conventional boiler power.
Steam turbines/reduction gear/shafts/props same regardless of 'power source' (which was still steam)

And very difficult to overcome 'physics'......hull speed & shaft rotational forces limit max speed

I'll stand on my previous numbers posted
Published number.......33.6KN
Hull speed formula.....43+KN (and not much over 43KN)----physics

YES .....
She could out run EVERYTHING out there at the time

Hey its not a contest....take a pill...!
All had powertrain installations designed to provide 280,000 shp except Forrestal which had 260,000 shp. In all cases, the power was delivered via four shafts. The turbines installed on the CVNs are identical to those on the CVs; they generate 280,000 shp over four shafts.

Don't need a pill....panties where never in a wad.

Just a discussion.

Correct about turbines......SAME regardless of 'Boilers' (Nuclear reactors just provide HEAT source to produce Steam)
Turbines are only capable of 'X' amount of steam flow which along with reduction gears/length-size of shafts/diameter of props---pitch etc is how (shaft horse power) SHP Rating is achieved.
280K shp per shaft

How fast a boat can go thru the water is more about hull design then which power plant used

Hull speed is all about physics......something even the Big E had to conform to

1.34 X sqrt hull length at water line
1.34 X sqrt of 1,040' (water line NOT overall length)
1.34 X 32.25 ------ 43.21 KN

Simple physics

Now give me the foot/pounds of energy at that speed and the distance to come to a complete stop! :-) I don't care what you say, that's a lot of energy in movement! WOW!

I landed on the E once in a Cessna Citation jet! :-) I was in the simulator taking a check ride (in the clouds, couldn't see anything) and the Instructor said to just keep a constant rate of decent going and not flare when the "runway" came in sight. I didn't know what he was doing. It came in sight about 100' above and I hooked the 3rd wire (or so he said). I looked around and saw the island in the visuals. Pretty cool. I said I could take off from the deck and he disagreed but allowed me to try. I asked for 35 kts over the bow and with full flaps and max power (102% N1) I rotated about 50 feet from the end a flew off. Well below Vmca, just above stall buffet.

Walked on the deck in San Diego and marveled at how big it is and yet so small to a jet doing 140 kts. The main mess was my biggest surprise at how tight everything was but the history, unbelievable.

A tip of the hat to all of you who wore a uniform. I'm in your debt. And to those who were carrier crashers, at night with a pitching a rolling deck-damn- I would have crapped my pants.

They are not the same steam turbines. CV's run on superheated steam, CVN's run on saturated steam only. Big Difference. CVN steam turbines are larger and have a much higher steam demand because of this fact. But SHP is close to the same.

All nuke plants produce saturated steam only. Therefore a lower BTU content per LB of steam.

I followed her around on a destroyer in the early 70's. We ran on JP-5 and refueled from her. It was amazing to come along side.

Hey what ever you snipes say about hot wet air is fine with me. I got it from a watch stander that was on the bridge at the time, and the number was larger then 33 kts.
As for ship speed factor, the only one I give two sh*ts about was the wind speed over the deck.

Mine was the USS Chicago CG-11, we were with USS Kitty Hawk CV-63.
and my camping bucket list is to watch a ship commissioning.

Come on guys, you don't know nothing about speed until you've been on an old carrier. I made three cruises on good old CVA 34 Oriskany 26 knts and a bent screw, shaking and blowing stack gas like crazy. I was on Coral Sea CV43 during the Libyan problem with Gaddafi during Operation El Dorado Canyon. We were operating just west of Naples Italy when we got the word to get down to the Gulf of Sidra asap. We made a constant 28 knots for about a day and a half I think. Ran right through the Straits of Messina at top speed with two escorts out in front of us and a Russian Heavy Cruiser trailing us the whole way. 28 knots doesn't sound like much in comparison to today's Navy but it was pretty good for that old lady, I was and still am proud of her. Coral Sea also had a bent screw. My berthing compartment was just to the starboard side underneath the number three wire and man o man lots of shaking and vibrating going on. That was back in April of 1986.
