Sadly we don't know the exact split of near-visiting types, but they have included the mighty Tu-95 "Bear" (shown with a Typhoon in the Crown Copyright image above) and the more menacing Tu-160 "Blackjack" (flanked by a Tornado F3 in the Crown Copyright picture below).
Eurofighter Typhoons are now solely responsible for standing "Q" in the UK, from their bases at RAF Leuchars in Scotland (which previously had Tornado F3s, prior to their retirement in 2011) and Coningsby in Lincolnshire. Others are currently held at short readiness at RAF Northolt to protect London during the Olympics, the opening ceremony for which is on 27 July.
