First ya need a gun…
Oops, gun in too big to fit in any current airplane… Need new airplane…
Hello, Fairchild-Republic? Yep, remember the P-47 Thunderbolt? Yeah, yeah, can you update that a bit? Couple of jet engines would be good; yep, tanks and stuff like that… Uh huh, A10 Thunderbolt works for us, kthxbi.
NOW we’re making progress just design the damn airplane AROUND the gun…
Make it Old School, butt ugly, powerful and with a Titanium Tub for the pilot, just in case… After all it IS going to be low, slow and shooting at things that CAN shoot back…
And just in case the bad guys get lucky, make everything at least doubly redundant (Old School- Belt AND Suspenders)… and triply redundant on flight control systems two hydraulic and one manual…
Capt. Kim Campbell sustained this damage over Baghdad and flew for another hour before returning to base. Story HERE. And here’s one by Michael Yon.
Get the biggest damn bullet you can, 30mm 6500 grains depleted uranium penetrator and push it real fast…
Just to put it in perspective, the .223 Rem (M16 rifle round) is fast. It shoots a 55 or so grain bullet at about 3300 feet/sec, give or take. It’s the fastest of all those rounds shown (except one). When you move up to the .30 caliber rounds, the bullets jump up in weight to 160-200 grains. Speeds run from about 2600 to 3000 fps or so.
The .338 Lapua is the king of the sniper rifles these days and shoots a 350 grain bullet at 2800 fps or so. They kill bad guys at over a mile with that one.
The .50 BMG is really big. Ask AEpilot Jim…
The bullet for the 30×173 Avenger has an aluminum jacket around a spent uranium core and weighs 6560 grains (yes, over 100 times as heavy as the M16 bullet, and flies through the air at 3500 fps (which is faster than the M16 as well).
The gun shoots at a rate of 4200 rounds per minute. Yes, four thousand. Pilots typically shoot either one- or two-second burst which set loose 70 to 150 rounds. The system is optimized for shooting at 4,000 feet.
How big IS the gun? Well, here is a PR photo done with an old VW Beetle…
Seven barrels, 112 inches long, total gun length? 19 1/2 feet long…
Oh yeah, stick a few hard points on the wings too will ya, we ‘might’ want to carry ‘other’ things…
And the Air Force Generals hated it, because it was ugly, and the gear wasn’t fully retractable, and they kept trying to kill it…
But the pilots loved it, the maintainers loved it, and they flew the hell out of them, and killed MANY things with them… And the pilots came home almost every time…
And they are STILL being used in combat, and are the ONLY true CAS asset the Air Force has…
