This BUG's been in service for what, 40 years? What do you think will eventually replace it?

Like there has been a need to replace the M-16, or the Browning M2?

Skunk, BUG=big ugly gun?:confused:

Kobun, notice he said "eventually". I'm not sure the M16 is a good example...
I'm thinking it will be replaced by lasers.

In aircraft there seems to be a move to replace/augment it with a laser weapon.

For ground based air defence I think the Army is replacing it with a 25mm weapon on a Bradley chassis. (Not sure about that, anyone know more?) I've also seen where they are trying to develop ground based lasers to take over air defense including shooting down incoming arty.

I have no idea what they're working on for ships, but I'm guessing it will be a laser system, or maybe something like the Metal Storm system.

I've shot this puppy. Nice piece! I come from South Africa, and did some work in the '80's with Armscor (the predecessor to Denel), so I had contacts there who invited me to come over and play during my last visit, early last year.

This gun was developed partly for long-range sniping (the 14.5mm Russian round was chosen in preference to the Browning .50 or the Russian equivalent in 12.7mm, because its ballistic coefficient over longer ranges is superior) and partly for ordnance disposal and soft-target assault activities. For the latter, the 20mm. round is much superior to the Browning .50 or the 14.5mm. Russian round, because it can be made in a genuinely high-explosive and/or incendiary configuration, causing much more damage to a target like a truck or aircraft than the solid round in the machine-gun caliber.

The recoil really isn't bad... I actually found it less than a Barrett .50 semi-auto rifle (I fired the Barrett some months after the NTW, so my memory may be playing tricks on me, but I seem to recall less kick with the latter). Very accurate, too.

Having spoken from guys who were soldiers when the m-16 replaced the m-14, and having been in the army myself, I believe that the m-16 leaves a lot to be desired. I have shot much more reliable rifles since I left the army. And if I had a choice, an ar-15 would not be it.

Not to bust on any ar-15 lovers, it is a proven weapon. And one I would, and DID use. I'd just pick something different if I had a choice.

The 20 mm is a wimp gun.

My beloved A-10 has the best gatling gun in the world baby!


TryThis site (http://www.a-10.org/a10-files.html) to see some action footage of the 30 mm Gau-8 gun firing.

Holy crap. One of those can really ruin your day.

but only for a second or two...

:what: :eek:

Lennyjoe, do you know why there is a difference between those two guns? The one sporting the peace sticker seems to be polished and the muzzles look like they are fairly flush fitting. The other is different there and also has a bolt and some sort of pin in it. :confused:

He sent it to Robar to have it hardchromed :D

Lennyjoe ... awesome A-10 vid! :)

June 21, 2003, 09:20 PM
If you look close, I think you'll see that the "chrome" gun just has a hub-cap type cover fitted over the muzzle clamp. I doubt that they fly with it on. It was probably made to snap into place for static displays at airshows and such.
And yes, the M61 is a nice piece of kit but 20mm is considered quite small for modern aircraft. Newer guns will be 25mm and up ...

D'OH!:banghead: Pretty obvious once it's pointed out.:banghead: :banghead:

Here is a good page that describes the workings of the mini-gun... same as the Vulcans only smaller.

Yes, the 30mm vulcan on a warthog. Gotta love hurttling Coke bottle-sized slugs of depleted uranium at anything that moves, like Iraqi-owned Soviet battle tanks.

I am sure yall knew this, did you know taht the plane was designed for the gun, and not the reverse?

June 22, 2003, 01:14 AM
Anyone have loading data for the 30mm Vulcan?

4000grains of H-870? :D :neener:

The A-10 is awesome when it shoots. Hearing one of those things let loose while in flight is something to behold. I used to see those things doing practice runs on an Army base with live ammo years ago. I'd just hate to be on the recieving end. I beleive that they load that 30mm with depleted uranium rounds, that penetrate almost anything.

Any plane that carries a 30mm gun, plus 16,000 lbs. of ordnance on either 9 or 10 pylons (middle 3 can't all be used at the same time), has my vote for most bad-a$$ed plane of the century. God bless Warthog drivers!

I wished I could have been an A10 pilot.. sadly, the old eyes are not up to snuff

Actually, the name "Vulcan" refers specifically to the 20 mm M61A1 or GAU 4 and to the M61A2. The 30 mm plinker found on the Warthog is a GAU 8 which is known as the "Avenger".
The correct generic term for this family of guns is "Rotary Cannon".

There's lots of info all over the net about these guns. A place to start would be by searching for "General Dynamics Armament Systems" or "GENDARM".

Buahahahaahahahaha! :)

Yes, but who makes a CCW holster for the 30mm Avenger?

IWB, preferably...

June 23, 2003, 02:09 AM
the only thing I can think of that would "holster" the Avenger cannon is a stretch Towncar limo or a stretch Excursion limo. Hopefully, it would pop up on a turret, and provide hours of entertainment.:D

I believe the sheeples' reaction to that would be: :what: :what: :what:

I have been keeping the A-10 flying for 17 years now and love every minute of it. You should see it loaded for bear and ready to rock. It truely is a site. Heres a pic of one with a static load. A static load is one for an airshow or display. Enjoy.http://www.imagestation.com/picture/sraid62/pb6ba0f57a1842145fbed48c94c68efc1/fc22b650.jpg

I'll bite :D

For fighter aircraft it'll probably be something like the Mauser BK27, a 5 chambered revolver breech cannon in 27x145mmB. This gun is already mounted (or slated for mounting) in the Tornado, Gripen and Eurofighter Typhoon. Apparently it's also been picked for the JSF, but I'm not sure about that. Using a revolver cannon instead of a gatling in aircraft makes sense since you have more or less the same reliability without mounting a full barrel for every chamber. I'm assuming that airflow is sufficient to cool after short bursts. Mauser has their website here (http://www.mauser-online.com/).

Helicopters don't use the M61 but some do use a three-barreled variant (the M197) and will probably continue to use it. Something will also be found to mount in the AC130s. Something always is. :D

Ground mounted vulcans, mostly AAA weapons, are pretty much a thing of the past. Mostly they've been replaced by AAA missiles. Of course, the US Army's AAA mostly sucks. It's very unbalanced, with no medium range missiles and no guns. Historically, infantry has found that AAA guns make great 'lawnmowers'. Look at how the M42 and M163 were used in Vietnam.

Naval vulcans, mostly mounted in Phalanx CIWS/AAA, have apparently been upgraded or have been replaced by Goalkeepers, which mount the GAU-8/A from the A10. Surplus Phalanxes are apparently ending up on supply ships or with the USCG.

Now a semiautomatic rifle in 20x102mm, that would be awesome! Probably tripod only though. The NTW-20 mentioned earlier doesn't fire this round, it fires something lighter (20x82mm IIRC).
