The MoD, which has been developing the Taranis along with BAE Systems, describes the unmanned drone as the "most advanced aircraft ever built by British engineers".
The supersonic aircraft is designed to carry a weapons payload of guided missiles and bombs.
The British military claims it will be able to operate the Taranis via satellite link from any location in the world, and, like US B-2 stealth bombers, it will be able to fly undetected by radar.
Far from prying eyes and measuring 127,000 square kilometres, the Woomera facility, dubbed Australia's Area 51, is - according to the Australian Defence Department - the largest weapons and aircraft testing range in the world.
The United Kingdom has a long association with Woomera, having conducted nuclear weapons tests there from 1956-63, along with the development of military rockets and various space projects.
