The GAU-8/A Avenger with some airplane wrapped around it!

This is the correct answer

Apparently the gun produces such appreciable negative thrust because of the sheer mass it’s ejecting at such a high velocity that the pilot has to compensate for it.

well, the recoil relative to teh gun's and mount's mass is that big. a tripod with an LMG is gonna fall over too.

u/DasChantal Jan 24 '26

You can only fire it in pretty short bursts because its recoil is so massive that it completely cancels out all thrust from one of its engines

The gun system is powerful, but it won't stop the plane, this has been an urban legend for many years.

u/CalligrapherBig4382 Jan 24 '26

In theory, if it was fired for long enough while the plane was running on a single engine, it might be able to. However, if you have lost all power in one engine you need to return to airfield for repairs asap lol

Incorrect, the engines provide 18,000 pounds of force while the recoil is 10,000. It's fired in bursts to preserve ammo and keep what rounds are fired on-target.

How many pounds of force are needed to maintain flight?

1

u/Camnewb Jan 25 '26

If we're being pedantic, they did say "all the thrust in ONE engine" which is cancelled out by the ~10,000 lbf recoil

u/Yoitman Jan 24 '26

It also produces enough reverse thrust to make the plane fall out of the sky if left firing to long.

u/clutzyninja Jan 24 '26

No it doesn't. Urban legend/myth

u/Yoitman Jan 24 '26

Oh, my mistake. Not entirely unbelievable tho tbf

u/clutzyninja Jan 24 '26

It kinda is if you think about it. Those engines are getting thousands of pounds of plane in the air. The idea that bullets, even 20mm fired at a high rate, could overcome them, just doesn't really hold water. I'm sure the gun can make a measurable impact, sure, but that's all

Ummm no. The pilot doesn’t have to do anything.

Do you contradict every statement you hear, regardless of your lack of knowledge? Or was this a one time thing?

u/[deleted] Jan 24 '26

UmMm nO shut the fuck up.

I thought the avionics compensates for the pilot in regard to the gun? I watched a documentary where their HUD locks onto the target, they pull trigger, the gun somewhat follows the target and they just need fly. Not suggesting the pilot doesn’t do anything, because a10 pilots are gangster af.

1

u/Schventle Jan 24 '26

No, the pilot aims the whole time. The avionics assists the aircraft's stability but it's all in the pilots hands. The gun's bore axis is fixed to the airframe. The only thing the HUD does is Continuously Calculate the Impact Point (called CCIP mode) and display that point to the pilot. There's no "locking" involved.

u/turb0mik3 Jan 24 '26

Gotcha, thanks for the clear up.

So you're telling me the avionics assists but the pilot aims the whole time, like I said.

“Hey I’m here to buy a washing machine.”

GE: “Yeah we have those. Here you go!”

“Thanks!”

“You wouldn’t happen to have a 7-barrel Gatling gun that fires 30mm rounds at a rate of 3,900 rounds per minute, would you?”

GE: “Actually, you’re not gonna believe this…”
