Ok, this is a U.S. jet, but in British service. I bought this one built to add to my phantom collection because of the unique markings. It is a Rolls-Royce Spey engined aircraft in 92 Squadron, 75th Year Commemorative markings; circa 1992. The British designation for the jet is an FGR.2.
You can tell is is a Spey engined aircraft because of the short parts of the engine sticking out at the tail.
