I'm bored, politics suck, the holidays suck, the world sucks. Let's talk about yhe big boomers instead:
Bofors 57 mm Naval Automatic Gun L/70 - Wikipedia
This thing can launch an 8lb or programable oprojectile at 3,400 fps and 220 rounds per minute. And its compact and remotely operated.
We should put this thing in AC130s, we should build a Self Propelled Anti Aircraft Gun. Remember SPAAGs aren't just anti air but anti EVERYTHING! The Russians learned this in Chechnya when their armor was nuked from the rooftops of tall buildings. Tanks and APCs couldn't elevate their weapons high enough to return fire but their SPAAGs could and with deadly effect.
In an AC130 Gunship the 57mm could blanket a large area with a wide variety of munitions and with the ability to hot swap between two in an instant. The 57mm could take over tge roles of the aged, tired 40mm Bogors L/60 and M102 howitzers and do the job better than either, could even engage armor from the top wear that armor is weak enough to get wrecked by a 57mm shell.
A 57mm SPAAG could turn ground combatants into paste from long range and uses all sorts of programable air bursting rounds to do it with. Such an SPAAG would be highly effective against helicopters and larger drones from a fairly long range and would be effective also against low flying aircraft. Basically could engage and destroy everything short of a main battle tank and even then 57mm AP could probably severely disable a tank from the side and definitely from the rear.
