My uncle flew on ... well I guess today it'd get the designation AC-3. A DC-3 that had 3 mini-guns sticking out the left side. His job was to stand at the very back and toss flares out the door so they could see what they were shooting. And helping get new ammo boxes from where they were strapped down along the centerline of the plane.
But yeah, the modern Spooky and Spectre have what, 105mm howitzer, a couple 40mm bofors, and some 7.62 miniguns? Did they change the loadout not long ago?
The Hercules is one of those things that so ugly, it's pretty. The A-10 is another warplane in that category.
