Hmm, in 1990 the RAF had three Tornado GR.1 wings (Marham, Honington and (sort of) Cottesmore), three Tornado F.3 wings (Leuchars, Coningsby and Leeming) and one each of Jaguars, Harriers, Buccaneers and Phantoms in the UK alone, as well as three training establishments with Hawks. Add to that the Royal Navy Sea Harrier squadrons and the USAFE presence of two A-10 wings and two F-111 wings, and there were rather a lot more fast jets around then.
The equivalent now is three RAF wings (2x Tiffie, 1x Tornado), one Hawk training establishment and one US F-15 wing.
