 The "Vampire III" was the first of several models that sought to address the demands for greater range from the type.Accordingly, underwing fuel drop-tanks of both 100 and 200 gallon capacities were fitted; other modifications included lowering of the tailplane and reshaping the vertical surfaces of the tail.The design changes to accommodate the hardpoint-mounted drop-tanks had the benefit of enabling the carriage of various stores and effectively readied the type for performing ground-attack duties.
