Inside the AC-130U Gunship
This is a fine ass kicking machine. The Lockheed AC-130 gunship is a heavily-armed ground-attack aircraft. The basic airframe is manufactured by Lockheed, and Boeing is responsible for the conversion into a gunship and for aircraft support. It is a variant of the C-130 Hercules transport plane. The AC-130A Gunship II superseded the AC-47 Gunship I during the Vietnam War.
