It's 20mm, not 25mm.....A minigun made of the Bushmaster rounds would be quite nice though, but the RPM on the 20mm is nice, 2000 to 6000 RPM depending on your settings.

These planes have a E-3/E-4 on board whose entire MOS and duty is to carry a shovel and shovel the excess brass out the door. Hopefully this falling brass hits a couple of Taliban on their head as they look up at the nice fireworks display.

"It's 20mm, not 25mm"

nope-

Late in the 1980's, however, the Air Force decided that it needed to upgrade the capacities of the AC-130, and the AC-130U project was begun. The weapons were changed somewhat, with the twin 20mm vulcan cannons being dropped in favor of a GAU-12 25mm rotating cannon.

It's 20mm on the AC-130H Spectre, but it is 25mm on the AC130U Spooky. From above, the 25mm round is efective against all armour.
