USS HARRY S. TRUMAN, At Sea (NNS) -- The aircraft carrier USS Harry S. Truman (CVN 75) conducted a full power run and rudder swing checks during sea trials July 8.
The ship rolled more than 13 degrees in each direction.
"After weeks of calibrations and testing, the ship's steering was finally put to the test," said Lt. Kasey Vowell, assistant auxiliary division officer for engineering department.
Truman maxed out at 30 plus knots during the run.

He's not being forthright with you. I watched out the cabin window of a 747-400 as the Enterprise caught up and passed us on the way to New Zealand. Disappeared over the horizon.

That’s jamming for craft that large.
Yes she has to do more than 40 knots if you look at the LWL. 1.34 x square root of the length at waterline gives you about 41 knots without over running the bow wave. Means she can likely push 45 knots if she has to.
Probably can if they ignore shaft longitudinal vibration limits.

Captain: Bootlegger reverse!
Helm: Bootlegger reverse! Aye Aye, sir!
Good point that I’ve never had pop up before. Nothing that big and spinning that fast can stay in perfect alignment.
No thrusters here, it’s basically a function of the fact that a turning ship rotates around a pivot point. Everything forward of the pivot point moves the direction of the turn, everything aft moves the opposite direction. There is also forward (advance) and sideways (transfer) motion in every turn. Laying out tracks on harbor charts I used advance and transfer tables that were entered with degree of turn, degree of rudder and speed to calculate where the ship need to start to turn to end up on the desired track.
the military channel (or A&E, or the science channel, or one of the few other channels that I watch) did a show on the construction and sea trials of one of our newer carriers. seems like it was the bush, but I don’t recall.
they filmed (or videoed, I guess) the high speed rudder test. it was intense. sailors were ridiculously close to laying on the deck to remain upright. on the starboard side of the hangar deck, all you could see was sky. on the port side, nothing but sea.
nothing that massive should roll over on it’s side like that.
On NIMITZ in the Spring of 1988 off the coast of Oregon we took a 24 degree roll (Air Wing was not on board). The wave that hit us knocked the ship 15 deg off course and over half the yellow gear in the hangar bay broke lose and played bumper cars.
Either he had no idea what he was talking about and was blowing smoke out of his ass, or he was having fun yanking your chain.
holy CRAP. what was the height of that wave?
Marines?
The Marines are the wet guys.
Like this?
I recall seeing the flight deck awash in green water as the bow went down and when it popped up we heeled to starboard and got pushed off course. Must have been at least 60 ft; the CO came to the bridge wearing his coffee and eggs.
I knew he was blowing smoke at me but the thing is nowadays if you repeat an exaggeration enough times, bolster it with a $100 million dollar campaign and also you employ a socialistic tutored army to patrol the internet suggesting its true then eventually enough of the herd says, “Well if he thinks its true then so shall I”
Just a small thread hijack on my part.
But I also hear the Japanese have a flying battleship....
Actually, the Burkes are good seaboats for being tin cans.
Damn, that looks like fun!
LOL! Yes it does. :)
