When the Royal Navy Fleet Air Arm decided on the McDonnell F-4 Phantom in the mid-60s, they made some modifications to minimize the gnashing of teeth in the UK. Notably Rolls-Royce Spey engines replacing the J79s (at considerable engineering expense). To allow the Phantom FG.1 (aka F-4K) to operate from the smaller RN carriers, there was also a nose gear mod to increase the angle of attack for takeoff from the smaller RN carriers and a folding nose to fit onto elevators.
To minimize deck damage, they attached a heat-resistant steel plate behind the catapult and periodically hosed the area down to cool it.
In the event, only one squadron operated Phantoms from HMS Ark Royal and only from 1969 to 1979, after which the RAF inherited the RN's Phantoms to supplement their own Phantom FGR.2s (F-4Ms).
