Lockheed AC-130 Spectre Gunship

http://en.wikipedia.org/wiki/Lockheed_AC-130

The AC-130 Spectre Gunship is a variant of the C-130 transport produced by Lockheed. It is used for close air support, and bombing raids. The Spectre Gunship can carry a variety of weapons from a 105mm cannon, a 40mm cannon, to dual 20mm cannons or a single 25mm cannon. Since the weapon systems are only on one side of the plane, the Spectre is required to fly a steady orbit over the target area. This allows the Spectre to bring all of its weapons to use for a long period of time. Because the Spectre Gunship is a big, and slow moving aircraft, it uses flares(shown above) to defend against missile strikes. The Spectre Gunship costs from 132.4 to 190 million dollars per plane.
