I would call it “thirtymumble knots”. The true top end of the CVN’s, much like the top end of our SSN’s, remains classified. Although that does not mean that the Dems have not sold that info, like a lot of other info, to our enemies.
It's not that classified. They've been building carriers for almost a hundred years and 32 to 34 knots is considered fast. A friend of mine was on the JFK when she did a post overhaul high-speed run and she did 33.5 knots. That's pretty good for 80,000 plus tons.
