The AC-130 gunship is just a modified C-130 cargo plane, but there is no more devastating array of firepower plying the skies anywhere in the world. The 130 started as a spectacular success in 1967 over Vietnam destroying around 10,000 enemy ground vehicles and devastating enemy troops. It's packed with punishing ordnance and renowned for its ability to fly in any conditions, at all times of day, for extended periods of time.
