The All Terrain Anti-Aircraft (AT-AA) was a quick-moving, quadrupedal, mobile anti-aircraft walker used by the Galactic Empire.

The AT-AA had four stubby legs and lizard-like locomotion, along with a low profile not seen in other Imperial walkers. On most models, the only weapon was a turreted flak pod, capable of firing several types of ordnance.[4] Other versions could be equipped with one or three rocket-launching tubes.[2] Initially the AT-AA had an inability to fire at ground targets. This was partially rectified with the addition of gun ports to allow the crew to fend off infantry attacks.[2]

Some variation had flak pods replaced with concussion missile launchers.[2] The AT-AA also carried electronic countermeasure systems that could scramble missile guidance systems, thus lowering the risk of missile strikes.[4]

Its preliminary designs were developed as far back as the Clone Wars, and the design began production early on in the time of the New Order.[4] The walker saw action during the Galactic Civil War, where it was used against aircraft, but was useless against any ground vehicles.[2] Although the troopers aboard could fix blaster rifle mounts on the vehicle, the AT-AA still relied heavily on escorting infantry vehicles,[4] including AT-STs.[3]

During the Battle of Kalaan, AT-AA batteries protected the armored columns from airborne enemies, bringing down scores of Alliance T-47 airspeeders.[5]

AT-AAs were used even in the time of the New Republic, where they defended the galactic capital from the New Republic Defense Force.[6]

Behind the scenesEdit

The AT-AA is the only Imperial siege weapon originating from the Expanded Universe to appear in all three of the major Star Wars RTS games.[7][5][8]
