There is no such thing as a AC-130E or a Pave Aegis as an operational plane.  That is an AC-130U... They have 25mm, 40mm, and a 105mm. W's don't have the 105, and J's don't have the 25. This is an old video. The U-boat does not fly combat missions anymore. The W and J are the only gunships flying downrange now.
