"Looks like a AC-130U Spectre Gunship...fabulous firepower."
Righty-ho!
105 mm, twin 40 mm, a couple of 20 mm's and a couple of 7.62x51 mm mini-guns.
Don't leave home without it
My company produced these things--13 of them as I recall. As is typical with most such programs, there were many speedbumps along the way but eventually our aircraft division guys got it all under control and delivered an excellent weapon system. I'm semi-retired now, and I don't know whether the Air Force ever ordered any more of them.
