bet you money it's more like 55 knots or more, they ain't gonna put out that info and older carriers can do that

saw a presentation a few years ago by a navy guy and he was asked about how fast the ships can go. he said he couldnt tell us but he hinted that 40+ knots was easily attainable

an old Tomcat driver buddy of mine was on a sea trial for a new carrier about 25+/- years ago and he said they were at 55 knots back then

that almost seems impossible. that is hauling arse

That's insanely fast. I was impressed with 40+ knots.

that's pretty smokin' but there has to be a point of diminishing returns, how fast does it need to go? the ships around it that it needs for support couldn't keep up with that

I've traveled "very close" to 40+knots at a depth of 500' on my sub.
I can only assume a carrier would be faster. But perhaps not

thought subs on the surface were among the fastest in the fleet

That's more what I was thinking. Back in the 80's the only escort ships that could keep up with a nuclear powered supercarrier were nuclear powered cruisers.
All else was left in their 90,000 ton wake

I guess when you have nuclear kW you're limited by things other than available power.

I dunno about that. Never ran very fast on the surface. Maybe another sub guy could answer that question

I guess close to the surface, where the water is less dense would be more accurate, the same guy that was telling me about the sea trial and I were flying from San Juan to Boston one day after a pretty big Naval exercise, as we past the group he was pointing out what was what and the different speeds, as we were about to pass them all up he pointed out the wake of the subs, just barely beneath the surface, and said that they are usually the fastest of the group

That seems unlikely, at least during flight ops. It would be hard for the crew on the flight deck to avoid being blown overboard, let alone actually get anything done.
With a clear deck maybe though.

I bet few could match our speed. The only ship that would come to mind is the USS Independence (LCS-2) which is a trimaran. Top speed is in excess of 44Kts.
I would doubt a sub could hit that speed on the surface due to cavitation of its propeller and the hull not being designed to plane out of the water.

We always ran fastest in the colder waters because the limiting factor became condenser vacuum in the exhaust boot of the turbines.
They'll go their fastest at about 200-300 feet in cold water. That's always where we tried to go ahead flank during drills/ ORSE/training to see what she could do.
Density at depth wasn't really a limiting issue but on the flip side, anything less than 200 feet and you start playing with drag from the surface of the water.
ETA: you're not breaking 20kts while surfaced. Hull shape is designed so poorly for surface operations. The cavitation of the prop and violent shaking of the sub became quite apparent at ahead full. We limited it to 16kts on the surface.

Operationally speaking if the ship is running at that speed, it is to avoid an ASM threat. I would doubt flight ops would be running at that time anyways.

it was a sea trial, sort of like a lot of fighters can do better than Mach 2 but we don't fight at those speeds

That's Farsi-cal.
