South Korean fighter KF-21 equipped with Gatling's "card holder"

_{Flight Simulation KF-21}

In South Korea, the process of creating the first national fighter KF-21 (claimed to be 4 ++ generation) is in an active stage: the first flight of the new machine is scheduled for 2022. Before it goes on its first flight, various aircraft systems, including combat ones, are being fine-tuned.

As reported on the website of the American company General Dynamics, a decision was made to equip the fighter with a 20-mm Gatling gun M61A2, which, as explained, "provides maximum rate of fire." It is 6000 rounds per minute, the ammunition load is 480 rounds, which are fed through a special conveyor according to the belt principle by a hydraulic mechanism.

The technical characteristics of the 20-mm KF-21 gun are indicated: total weight - 294 kg, gun weight - 91,6 kg, feed system - 123,8 kg, ammunition - 122,5 kg. As explained, the gun is compatible with all 20 mm M50 and PGU series ammunition.

The KF-21 is designed to update the outdated fleet of South Korean fighters, which is represented, in particular, by such machines as the KF-5 (about 80 units) - a licensed version of the American F-5. One of the aircraft of this type crashed on January 11 of this year (2000 F-12s have been lost since 5). The 29-year-old pilot died as a result of the crash.

According to preliminary reports, Major Shim Jong Min deliberately did not eject to prevent civilian casualties during the KF-5E crash, driving the plane up a hill located 100 meters from civilian housing.

American not new aircraft gun - a lightweight version of the "Volcano". It has already been discussed at VO.

but it will not fall apart from the shots of the "gatling"?

[Klingon]

What's this? The entire ammunition load in 4,8 seconds? gee... - geyyy
Although if you make half-second volleys then ... But who will shoot from a cannon at all? Except in DCS

[Sahalinets]

Dryers release the entire BC in six seconds, MiGs in four.

On the MiG-27, the six-barreled GSh-6-30A ammunition was enough for 3,5 seconds of continuous firing. True, at first the cannon could shoot only half of the ammo with one burst without any problems.

usually fired in short, fixed-length bursts. Electronics allows. In addition, the weapon control system tells the pilot (by changing the aiming mark to the HUD) when it is better to shoot and the probability of being hit is the highest.

What is the point of a multi-barrel gun on a fighter? It takes up a lot of space, it's easier to install a single-barreled one like on Su. Enough for air combat. And on the ground in the USA, as a rule, guns do not work. The exception is A-10C, but he is an attack aircraft.

Americans have been flying for a long time ..... it’s not for us to teach them

It's just that the M61 has been in service for 60 years. Serial product, proven design, standard gun for American fighters since Vietnam. Developing a new single-barreled or twin rapid-fire aircraft cannon is long and expensive.
However, the Yankees also have alternatives - 25 mm GAU-12/U (5 barrels) and GAU-22/A (4 barrels) gatling guns.

[Klingon]

I think so too. The multi-barreled one is an order of magnitude heavier, the trunks of the striped multi-stalls spins the electric drive, which
also has a lot. Okay, the A-10 is a separate issue, the whole idea is in this gun to which they just attached wings and 2 engines. A fighter is another matter. Here mass matters, a large mass increases inertia in turns and wing loads
And by the way, single-barrel guns have a fairly high rate of fire. But in DCS, yes, it's cool to shoot from such a gun

M61A2 weighs only 92 kg

drive M61A2 - hydraulic

[Klingon]

Why is GSh-23L worse? 2 barrels, rate of fire 3000-4000 rpm, weight 50 kg. No need to bother with the power supply and drive, and ... Well, okay, apparently THERE do not know how not to be expensive and angry.

[Tomcat_Tomcat]

The Americans have a vented version of the "Volcano" - GAU-4A

And in general - two different schools. Each scheme - an external drive and a gas outlet (gas engine) - has both its pluses and its minuses, about which a lot has been written.
And without a power supply, guns of both concepts will not work - in modern aviation only electric triggers are accepted, as well as cartridges with electric ignition. Not to mention that in the event of a power loss, the sighting system will not work either. In general, it is not possible to shoot on modern aircraft without electricity.

Honor and praise to the major... Died like a warrior.

[Kaw]

If there is a Gatling shotgun, then the pilot must turn the handle.

[Kaw]

And the food there was not from the tape, but from the clip.

[Andrey Moskvin]

Weapon of last chance?

[Phoenix]

Who called this weapon a gambler, journalists or translated? Where is the buckshot, can you explain?

When Gatling created this device, it belonged to the card holders.

[Phoenix]

This is not a Gatling weapon, but a modern rotary autocannon looked at according to the Gatling scheme. There is a difference.

[Zoomlion]

And who will turn the pen in the card case?

[Andrey Moskvin]

Like who? Second pilot.

Electric motor. Chain driven.
More reliable than a gas return system,
do not need to be cleaned of carbon deposits. Stable, adjustable rate of fire.
Disadvantages: larger size and weight of the gun.

In aviation, on a fighter plane in our time, a multi-barreled gun will make one burst, well, maybe two bursts and that's it ...
The cannon and the entire projectile feed mechanism will be cleaned already on the ground ... if the plane returns.
In aviation dimensions and weight have always been a priority - otherwise the plane will not take off or something will not fit.

No. The gun fires clips. For 10 turns, it seems.

Can the automatic gun shoot bursts of 10 rounds.
I was talking about these queues - in an air battle there may be a case of "close combat at close range", but even then 1 or 2 bursts, then everything, return with a shield or on a shield.

Not being finalized ... You need to charge with a shot, the number of bullets will be more.

RF 15 1945 - 15 bullets in one cartridge, USA.

USA perverts! I have long suspected.

The main thing is that the recoil does not stop the plane when firing ...
