Re: O2 many issues @Dave
That depends on what you call a fast jet!
The only supersonic jet that was deployed on UK carriers was the F-4K Phantom II (FG.1), which was a US design re-worked with British engines and avionics. Only the Ark was capable of flying the F-4K. as Eagle has not been fitted with the reinforced and water cooled blast deflectors that allowed the Ark to operate them. This meant that the Eagle was withdrawn from service before the Ark, even though it was actually in a better state of maintenance (I very sadly saw her in her last days, moored and in reserve at Drakes Island in the Plymouth sound).
Ignoring the Harrier, the last UK produced 'fast' plane was the Blackburn Buccaneer, which was a formidable surface attack aircraft, bot not supersonic. Prior to that it was Sea Vixens, Sea Venoms, Scimatars, and Sea Hawks. All of these were designed in the '40's and '50s, and were regarded as 1st of 2nd generation jets at best.
Amusing story. The F-4K needed afterburners in order to launch with full weapons load (The Spey engines were less powerful without afterburner than the US General Electric J79 engines fitted to the F-4J). When joint operations with the US happened, it was found that the heat of the afterburners, and the increased angle as a result of the lengthened nose wheel would soften and melt the deck and blast-deflectors on the US carriers,which meant that the UK planes were not welcome on the US carriers.
