To me it looks like a Hawker Sidley Harrier Jump Jet. The old type had blunt noses, but the later ones were fittled with Radar which looked just like that.
Well i must say this has been the most succesfull quiz sofar...
Good answers but all wrong... The aircraf on the pic was MiG-23PD...an early prototype for the Flogger. The main goal was to produce a good STOL fighter and MiG went on whit two ways, The VG variant wich at the end won the contest and this version whit two RD-36 liftengines (same as in Yak-38). This concept proven out not to be so practical (basicly by the same reasons why the Yak-38 wasen't so practical)
