British requirements in a Crusader III counterfactual

What would the Royal Navy change if it adopted the XF8U-3 Crusader III as its F-8 equivalent?

The requirements are too unclear for a firm redesign, but the proposed missile-carrying role would raise major carrier-size and compatibility questions.

The aircraft choice is too underspecified to establish what Britain would change. British adoption of the Phantom does not establish a requirement for an F-8 equivalent. Under the proposed missile-carrier interpretation, the aircraft could provide an early launch platform for an anti-ship cruise missile. The imagined weapon is roughly half as long as the aircraft and would make carrier compatibility a major constraint. A Malta- or CVA-01-scale carrier enters the scenario as a possible requirement for operating the combination.
