30mm vs 20mm cannon (or somewhere in between)?
20mm to fighters and 30mm to interceptors.
>>65161725depends on the use case
Bigger calibers give them better damage in games
30mm is overkill for air targets even for bombers.
>>65161725If the weapon in your pic was more reliable then 27mm is ideal.
>>65161725GIAT 30 791 Powerful round, reasonably compact, and is electrical, so less chance of jam on misfire.
Why not use a 50 cal rotary cannon with an even higher rate of fire?
>>65161765there's a practical limit to ROF without going to multiple barrels/guns and a proper cannon round can fit way more explosives inside. Youd rather 1 of the 5 cannons rounds you fire in the 0.2 seconds the gunlines up hit than 3/17 rounds in some super high rof 50 cal hit, probably
Will we never again see attempts like the German 20mm thin-shell, high-capacity ammunition?
>>65161744that was already not true in back 1942 none of this matter anyway, modern air combat will probably never see air to air gun kill ever again gun are only useful for shooting cheap drones and even that is being done by other drones now
>>65161765The GAU-8 wasn't even the biggest autocannon the USA did. They did a 35mm on a prototype SPAAG iirc. Or something like that.
>>65161764GAU-19 exists, anon. It was meant for rotary aircraft, though they thought it could go on fixed wing aircraft. It never did.
>>65161725Depends on what you're shooting at. Fighters? You want that higher rate of fire just to get hits in. Ground targets? 30mm has a bigger blast radius. >>65161818Not necessarily. Missiles are bulky and expensive. If you want to shoot something cheap like a cargo truck or drone it's more efficient to use guns rather that waste the limit stock of missiles.
>>65161832It was 37mm, but the barrel was a bit shorter than the GAU-8 and it lacked the feed system, carrying a ridiculously tiny internal magazine. I think the eventual idea would've been to have it connect to some kind of external ammo supply but it never got that far in development.
>>65161845>If you want to shoot something cheap like a cargo truck or drone it's more efficient to use guns rather that waste the limit stock of missiles. Guided rockets have better range and accuracy. And you can carry quite a decent number of them in a pod. Plus they're not big-bucks expensive, like full-size air-to-ground missiles (ex. Hellfire). Guns on aircraft make sense in turreted mounts on helicopters, to poke holes into some shitty technical. Not very useful on fixed-wing craft.
>>65161725Why not go for a 57mm flak gun? Longer range, greater area affected, much more useful against soft targets on the ground too.
>>65161856If you're going to go big you might as well go all the way.
>>65161861I mean, if we're going ALL the way then the Italians put a 102mm anti-ship gun onto one of their bombers.
>>65161845>If you want to shoot something cheap like a cargo truck or drone it's more efficient to use guns rather that waste the limit stock of missiles.using a gun mean you need an expensive platform to mount and aim it, it also mean you have to be in range of return fire which is a completely unnecessary risk now Ukraine barely use any guns to take out shahead now, most of them are taken out by jamming and fpvs same goes for ground targetthey are raining down fire with on russian convoys with fpvs 160km inland now
>>65161847Say if Meltrandi were a thing would that be the perfect weapon for them or would they need something larger?
>>65161866I'm unsure whether or not that one was ever actually an autocannon. An autoloader was designed for it but there's no record it was actually completed or installed on any of the prototypes. If it was it would be the record for biggest autocannon by caliber though.
>>65161890The P.108A looks like a big enough airframe that you could include a few loaders for gun on the aircrew. Also doesn't it take more than an autoloader to make an autocannon? Or are tanks with autoloaders all carrying giant autocannons?
>>65161887>pisses itself when firing hot loadsOMG he's just like me!
>>65161856too much recoil and stress on airframe
>>65161847The feed system on this is wild.It's a real life clipazine.>fed by 6-round clips which were loaded into a 32 clip pan magazine>192 rounds total, with a variable rate from 120 rounds/min to 3000 rounds/minIt's downright cruel.A gun clearly made to exist in some awesome metal slug reality constrained by our boring, disappointing one.
>>65161725I used to work on 27mm Mausers, feel free to ask questions I guess
>>65161896I think it comes down to rate of fire. The BK 7.5 could put out 30 rpm (and is generally considered an autocannon), while tank autoloaders typically put out less than 10.
>>65161911That's pic unrelated ofc just the same feeling.Here's pic related in the T249 Vigilante
>>65161924
>>65161896>>65161890Excluding artillery or naval guns the largest automatic cannon that sees widespread use is probably the KS-19.
>>65161771Whats up with the wierd shell in the 30x165? Is it some kind of APCR ?
>>65162136it's for turks
>>65162136Ribbed for her pleasure
>>65162136It's a prac round. There's a incendiary/spotting round that's a similar shape, called 3UOR6IIRC they're shaped that way to alter its ballistic coefficient to match the main 3UOF8 HEFI trajectory, even though it's not the same weight
>>65161919>I used to work on 27mm Mausers, feel free to ask questions I guess How many recocking rounds are usually carried?
>>65161725>The Great Debate 30mm vs 20mm cannon Missiles>but what if you run out of missilesGet more missiles>What about shooting drones.50cal on something that isn't an 80mil Stealth Jet>what abut strafingDon't>but A-10Retire or convert to drones
>>65161938The KS-19 has mechanically assisted loading but is not autoloading. A guy has to drop a shell into the tray every shot.
>>65162939Makes you wonder how many conscripts it ate over the years
>>65161845>If you want to shoot something cheap like a cargo truck or drone it's more efficient to use guns rather that waste the limit stock of missilessorry, but I think this is a false economyin anything other than forever-GWOT the stand-off missile is saferit's better to use a $100,000 missile than to mount a cannon on your $100 million jet and hope the other side isn't packing MANPADS or doesn't get lucky with his 23mm Shilka
>>65164214the gun goes inside the aircraft, you get the missile as well
>>65161887That's some Battletech AC5 shit right there.
>>65164246>Battletech AC5 shitis literally WW2-era Bofors forties, even radar-guidedcassette clips, remember>>65164227leaving aside that there is no free lunch and the space the gun and magazine occupies inside the aircraft could have been used for fuel, sensors and internal missile bays, the point of my post was that there is no real reason to mount a gun other than GWOTand even then, modern PGMs are just better and safer. the RAF fired a grand total of thirty-seven (37) Eurofighter cannon shells at ISIS. and I'm not convinced that it wasn't an ND.
>>65162524None, as far as I know. If it jams, it stays jammed. But that was really rare. The first three rounds were inert TP, if some dumb mf forgot to remove the barrel cover they would blast it away.
>>65161919have any actually been fired in anger?
>>65164288Tornados and Typhoons carry them, so most liekly somewhere in the sandbox
>>65164246Its what the autocannons in JabroniTech are actually based off a fact that eludes most smoothbrains and even grogs.
>>65164288They have in Syria. RAF complained about feed issues.
