Looks like there was a plan B after all...
Meanwhile, urgent modifications were carried out on Nimrods to fit them with ex-Vulcan air refuelling probes, a version then designated MR.2P. The MR.2P was also given the ability to carry Sidewinder AAMs, Stingray torpedoes, AGM-84A Harpoon ASMs, and 1000lb iron and cluster bombs. In the event, none of these weapons was actually used in action.
XV229 made the first flight with just the AAR probe installed on April 27th 1982; this was enough to allow crew training to be carried out. The actual fuel plumbing was very much a jury-rigged affair, but it allowed probed MR.2s to fly missions lasting up to 19 hours, refuelling from Victor tankers.
