names of guns on jets?

It’s been years, but I think there was ( might still be) a term referring to a “SUU” armament which I believe was centerline on the F-4 Phantom Aircraft.
One of the birds in a revetment for reasons I never learned, fired off the weapon. It was a fatal incident as from what I remember. I saw what it had done to a pick up truck and a wheeled fire extinguisher. I never saw the poor soul who died. This was in Korea either in ‘74or ‘75.

A year or two earlier in Taiwan I responded to an incident which for an armament crew was fatal when an AIM-9 missile launched and detonated.

Cannons, I believe. Varied mounted positions, and calibers.

Notable, the A-10's GAU-8/A Avenger -- 30 mm hydraulically driven seven-barrel Gatling-style autocannon at 3900 shots/min. It uses dense, spent uranium shells as rounds against armoured vehicles.

The F-16 20mm M61A1 six-barrel Gatling gun and a linkless ammunition feed system. The 6,000 shots/min

AC-130U/W Spectre gunships and replacement--- AC-130J Ghostrider ---three side-firing weapons, a 25mm Gatling gun, a 40mm Bofors cannon, and a 105mm howitzer

So one of my most hated film moments os when the writing team don’t know the difference between a cannon and a machine gun.
Yes it’s red tails where an American pilot takes 3 mk 108 30 mm cannon shells ,form an me 262 to the chest and carry’s on fighting lol
Each round having a similar amount of explosive as a hand grenade his cockpit and body would be destroyed.

As a counter in the Captain film it really looks like the prisoners have been hit by a 20 mm flak cannon. It’s a great film shows how a true story can be shown.

most combat - air superiority, or ground support jets have some form of gun armament; they learned the hard way with missile only armed f4s severely limited the effectiveness the craft.
older version used .30 to .50, with occasional 20mm cannons. most modern variants use 20-30mm electric gatling guns.

Cannon fires rounds which explode, machine gun fires rounds which don’t. Not seen modern jets with machine guns, though the Americans have one with a gattling gun that tanks are afraid of.

Modern fighter jets have multi-barrel rotating cannons, similar to Gatling guns.

"Gun" is the general term. "Cannon" is a specific type of gun, like "rifle," "pistol," "revolver," "shotgun," etc.

Cannons fire explosive shells of many types, Machine guns fire solid bullets though both may fire tracer to show where the rounds are going.
