Re: SkippyBing a navalised Typhoon
True, but if the best you can do is launch a Typhoon with an air to air load and partial fuel I can't see you getting a second one off the deck with enough fuel to transfer across. With the F-4 the catapults could get you off the deck with a full air to ground weapons load and as much fuel as you had room for. The second Phantom could then load up with full internal and external fuel and top up a number of other aircraft once they'd climbed to altitude and got to a more efficient flight regime.
A better comparison might be the Buccaneer S1, which like the Typhoon, couldn't get off the deck with a full weapons load and fuel because of some rather anaemic engines and weak catapults on the carriers in service. In that case tankers were used, but they were normally Scimitars, which could launch with full internal fuel and an external tank on each pylon. But that's not an option for Typhoon as if we had a fighter that could launch with that much payload we'd probably want to use it instead!
TL;DR, You need a tanker that can carry lots of fuel, Typhoon can't.
