"Aircraft carriers offer a more rapid.....means of establishing and sustaining an in-theatre airborne capability than land-based squadrons."
So how long does it take for Invincible to get to the Gulf? Last Jag Sqn to go took 3 days (with a day off) to deploy 10 jets with attack, recce and PW II + PW III/TIALD capability. Oh, and they could take off with the stuff on and bring the whole lot back all year round.
