"There is no such thing as society" - Margaret Thatcher
-
I think that an Oscar firing a salvo of P-700's would be about the only thing that would have a fighting chance of scoring a hit on a USN carrier, as it is the only platform with enough weapons that would reliably get to within launch range.
However, I still think the carrier would have good odds. When we say that the Oscar is going to launch all of its missiles, are we talking about firing all of them at once or consecutively with a few seconds in between? I would have thought that if it fired all 24 at once that the combined backblast wouldn't do the submarine or crew any good, so I figure the latter is the case. Assuming that I am correct you are probably looking at a minute between the first and last missile being launched, which gives AEGIS time to switch its fire control radars to new targets as the original ones are engaged. When the SM-6 comes on line this won't even be an issue as it has an active radar onboard for the terminal homing stage."There is no such thing as society" - Margaret Thatcher

Why would would only the F-15 be limited in this case when Sparrows/AMRAAMs are carried semi-conformally and sidewinders are little, low drag loads, while the Mig-25 isn't with its stinking big missiles?

Yep - all the max speeds you see on those planes, cut'em down by 1/4 or so when they are fully armed. Won't give a precise answer, but close enough. The Raptor would be the exception here.
You can find some -1's for USAF aircraft or in some cases NATOPS publications for USN aircraft with performance charts on the net. Sometimes you can even find them for free - either way they are not usually classified as they just give you an overview of the flight capabilities rather than weapon employment specifics, tactics etc - assuming you're ever curious about it :)

Again, I'm happy we'll never know how efficient AEGIS isWe're so bad, we're even bad at it

Hmmm... my own F-15 dash one shows missile carriage & employment limitations to be "BAL", Basic Aircraft Limits. There are definitely mach limits on external fuel tanks of 1.5 mach, but an otherwise clean F-15 (missiles only) can fly and fire them throughout the aircraft envelope.
I'm looking in section 5, "Operating limitations", "External stores limitations without CFT."
What anything hung on the airplane definitely does do is contribute to an overall Drag Index that hinders performance. You calculate the DI of a particular configuration, and that can tell you how performance like range, ceiling, and acceleration are affected. We'd normally fly with a single centerline tank, one practice AIM-9, and that is designed to simulate the DI of a 4 X 4 loadout.
I'm confident most fighters with external stores have similar methods. Regardless, anything above mach 1.4 is really not a normal combat speed. You become a high-speed dart that cannot turn well, and while this may be fine against other jets, the major SAM systems find the high-speed target to be a pretty simple solution below 50,000 feet. The sweet regime for combat ops is usually between mach 0.8 and mach 1.4.

You have to look at the performance (max speed) charts for an F-15 in combat configuration and 97% engine trim.
Incidentally, just having looked myself, I may have been wrong: Looks like the 1.8 mach limitation might be on the centerline tank, and you can hit M2.2 or so without it. Then again, once you go supersonic with the tank you're not going to jett it (it'll come back up and hit the plane).

A hit on the flight deck, or the island, or an elevator, in short, any hit tthat prevents the carrier from operating planes, and that's it. No more carrier. Also, how much speed does the carrier need to launch fighters with a usefull weapons load? 30knots? Loose the rudder or a propeller..."Only Nixon can go to China." -- Old Vulcan proverb.
