Airbus A400 Grizzly
The Airbus A400 is a military transport aircraft, roughly sized in between the Lockheed Hercules and the Boeing C-17. It is quite easy to recognise, because there are no other four-engined turboprop aircraft with high wings and a T-tail. You are more likely to confuse it for a Boeing C-17, which has a similar silhouette (but is a jet), or the Antonov An-70, which also has multi-bladed propellers, but not T-tail.
There is essentially one version of the A400, the A400M. The aircraft is designated Atlas C1 is Royal Air Force service.
Confusion possible with
While the C-17 Globemaster III has a very similar silhouette as the A400M, the C-17 is a jet aircraft and the A400 a prop aircraft. Also the A400 is smaller than the C-17.
The An-70 is also a prop-driven transport aircraft, and of the same size as the A400. However, the An-70 has a conventional horizontal stabiliser, attached to the fuselage instead of on top of the vertical stabiliser.
