The City Destroyer is an aptly named vessel used as the main attack force of the Harvesters in the film Independence Day. Thirty-six of these city sized craft positioned themselves over major population centers around the globe, then waited until the right time to strike. After obliterating the cities below, they would move to their next target, then repeat the process until there was no chance the local population could fight back. The main and only weapon the Destroyers have is a central energy projector (called ''Energy Cannon'' by the Independence Day Wiki) capable of vaporizing their target, then creating an explosive chain reaction 15 miles, or 24.14 kilometers in diameter. The ship's hull was protected by an energy shield that could block both solid and explosive projectiles (including, but not limited to a nuclear detonation), but also carried a compliment of at least 500 Attackers. However, the exact number of Attackers is unknown. According to the expanded universe novel Independence Day: War in the Desert, an additional indeterminate number of Attackers were still on their launch arms when a particular Destroyer was boarded.
