The entire Atlas fleet will be based at RAF Brize Norton. The A400M will replace the C-130 in RAF service but, because it can carry approximately twice as much load, or the same load twice as far, fewer aircraft will be required.
Uniquely it is able both to cruise at jet-like speeds and altitudes over intercontinental ranges due to its extremely powerful engines and advanced aerodynamic design, as well as to operate repeatedly from short and unprepared airstrips close to the scene of military action or humanitarian crisis.
