The Airbus A400M Atlas is a European four-engine turboprop military transport aircraft. It was designed by Airbus Military. The Airbus A400M provides substantial improvements to payload, range, internal volume and operational capacity over the Transall C-160 and Lockheed C-130 that it replaces or augments. It can carry up to 37 metric tons (41 short tons) over 2,000 nmi (3,700 km; 2,300 mi). The cargo box is 17.71 m (58.1 ft) long excluding ramp, 4.00 m (13.12 ft) wide, and 3.85 m (12.6 ft) high (or 4.00 m (13.12 ft) aft of the wing) and can be configured to transport cargo, military personnel, drop paratroops, conduct medical evacuations or carry out aerial refuelling. It can operate out of short, soft landing strips and fly long-range cargo.
