The Anti-Air Turret is a Turret that is available in Tech Level 3. It costs 20 Carbon and 150 Ore, and can attack Aircraft. In Tech Level 4, it can be upgraded to the Adv Anti-Air Turret at the Research Center for 200 Carbon and 500 Ore.
The Anti-Air Turret is a deadly defense against aircraft, but cannot attack ground units, so it should be protected by Light Turrets or their upgrades. Air Cruisers outrange Anti-Air Turrets and can easily knock them down from range. Enemies can also use Cannons or other Heavy Weapons to destroy them.
"First available at Tech Level 3, Anti-Air Turrets are specifically designed to fend off aerial assailants from long range. They cannot attack ground units."
Clone Campaigns changes Edit
Originally, the Anti-Air Turret cost 20 Carbon and 100 Ore, and had 20 attack, but did bonus damage to Aircraft (a strange choice, considering that it couldn't attack anything else). The price was increased in the expansion, and the bonus was removed in favor of a higher base attack.
