The dirigible to be purchased with the money secured by the popular subscription organized by the Morning Post was ordered from the Lebaudy factory at Moisson in July, 1909, to be delivered directly through the air to Farnborough before November 6, 1910. This stipulation was severe enough, but furthermore the vessel was to be a considerable departure from any thus far built at that famous factory, and was to be the largest air ship yet constructed in France. As usual the general design of the huge balloon was entrusted to the distinguished aëronautical engineer, Henri Julliot, and this was a certain guarantee of its successful operation.
