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

CharacteristicsEdit

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.^[3] 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.^[3]

HistoryEdit

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.^[3] The walker saw heavy action during the Galactic Civil War,^[source?] where it was used against aircraft, but was useless against any ground vehicles. Although the troopers aboard could fix blaster rifle mounts on the vehicle, the AT-AA still relied heavily on escorting vehicles.^[3]

During the Battle of Kalaan, AT-AA batteries protected the armored columns from airborne enemies, bringing down scores of Alliance T-47 airspeeders. AT-AAs were used even in the time of the New Republic, where they defended the galactic capital for the New Republic Defense Force.

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.^[4][5][6]
