Scale: 1:96. This model was made as part a joint feasibility study by shipbuilders Yarrow & Company Ltd., the Admiralty Research Department and the Atomic Energy Authority Industrial Group, into a nuclear powered Royal Fleet Auxiliary ship (1965). The midship areas of both sides of the model and the midship deck and superstructure have all been exposed and ‘glazed’ over with transparent material, possibly thin perspex. The large cutaway section allows the internal compartments and machinery, including the nuclear plant, to be viewed. The forward of the two funnels, and other deck-mounted features, have also been partly made from a clear material. Where the midship section of the deck itself has been rendered transparent, fittings such as winches have been placed upon it in their correct positions. The more conventional features of a replenishment tanker, like the fuel booms, can be seen, too. The advantages are obvious of a fleet replenishment tanker that can remain at sea indefinitely.
