I wouldn't know about the truth of it but they won't buy it off the shelf. They'lll want mods and structural changes and then it will come in late and overbudget as usual.
Think back to the mess that was made of adapting Argosy for military service. One set of doors welded shut, heavyweight floor fitted and couldn't get a Bedford 3 tonner into it without special gear to compress the suspension so that it could fit into the height of the load space. Typical load in Gulf summer was Aden to Bahrain, possibly with a stop at Masirah, carrying 12 men or a ton of freight. Also could not reach safety height to go Bahrain to Akrotiri via Norther Route (Iran and Turkey) ISTR
