XM655 is a B Mk. 2 Vulcan, and the youngest Vulcan in existence (the third to last produced; XM656 and XM657 have both been scrapped). Delivered to 9 squadron at RAF Cottesmore in November 1964, she went on to serve with 50 squadron, 44 squadron, then back to 50 squadron, and then back to 44 squadron again. XM655 returned to 50 squadron and was put up for disposal in late 1983. She was bought by businessman Roy Jacobsen who had hopes to fly her on the airshow circuit.
