Talk:GAU-12 Equalizer

message: My understanding was that the gun for the F35 was a variant of the Mauser 27mm which was being modified by Boeing. I had heard that the GUA-12 was being looked at but the 27mm was the favoured solution technically. Possible that a political decision on buy American has been made though since the last information I received. —Preceding unsigned comment added by 149.8.248.2 (talk • contribs) 
:Hogwash. As you can see, the GAU-12 and the M-51 are both based upon a  Norwegian  design. Let's not go painting an entire country a bunch of nationalist fascists. At least not without a source. ... aa:talk 01:09, 4 December 2006 (UTC)

message: Why the huge rate of fire and tiny, tiny ammo loadout?  180 bullets on a $20m fighter? Wtheck?
: Well, let me guess: The huge rate of fire is necessary to keep the rounds in the target while the airplane is moving sometimes at an extreme high speed, sometimes even supersonic speed. The ammo load is limited due to space and weight constrictions on the airplanes. --134.155.99.42 (talk) 22:12, 25 February 2008 (UTC)

replies: text: That picture isn't of a GAU-12/U.  The GAU-12/U only has five barrels.  That is a picture of an M61 cannon.  See here http://www.gdatp.com/products/PDFs/GAU-12U.pdf  I'm deleting this picture and correcting the article information on this matter. -- Thatguy96 04:17, 23 April 2007 (UTC)
replies: text: On Commons there is a  but it shows six barrels. If it's good, it should be used in this article. But if it's bad (i.e. the gun pictured is not GAU-12/U) then its title should be corrected directly on Commons. This picture is also used in the Wikidata item for GAU-12 so the correction should also be applied there. 192.198.151.36 (talk) 11:58, 5 September 2019 (UTC)

text: There is a picture on General Dynamics official page that has been "Approved for Public Release" (link).  Is this a sufficient claim for adding the picture to Wikipedia under some image licensing scheme?  I feel the description is ambiguous... it could just be "approved for public release" as in "unclassified".  Thoughts?  This page could really use a decent picture.   Amit  ►  18:09, 23 August 2010 (UTC)

message: :The Harrier II carries the Equalizer system in a pair of pods mounted on the fuselage sides, with the cannon in the port pod and 300 rounds of ammunition
Is this correct? At the rate of fire of 3,600 rounds per minute, this is only enough for five seconds of fire? (moved from text by BillCJ) - BillCJ 17:36, 17 April 2007 (UTC)
replies: text: Yes, rarely do aicraft fitted with "gatling" style weapons have more than 4-7 "seconds worth" of ammunition.  The largest capacity I know of was on the F-105 Thunderchief, which had ammunition for over 10 seconds of sustained fire.  -- Thatguy96 04:31, 23 April 2007 (UTC)

text: This is fairly typical for modern aircraft. The F-16 carries 511 rounds with a 6,000-spm rate of fire, the F/A-18E & F carry 412 rounds with a dual rate of fire selectable between 4,000 and 6,000 spm, the F-15E carries 500 rounds with the same selectable rates of fire, and the F-22A carries 480 rounds with a 6,000-spm rate of fire. All translate to 4-5 seconds of firing (all data from www.gdatp.com). VTFirefly911 05:43, 16 September 2007 (UTC)
thread_title: Ammo load

message: The complete alpha-numeric portion of the designation for this weapon is GAU-12/U.  The /U is not a seperate variant, it is the only variant.  There is no six-barrel version of this weapon either, the Global Security entry which is unsourced is incorrect and does not match published print sources or the manufacturer's specifications.  Furthermore, the GS entry notes this "six-barrel" version as being fitted to the AC-130.  The AC-130U uses a five-barrel GAU-12/U.  -- Thatguy96 04:30, 23 April 2007 (UTC)

thread_title: GAU-22

message: Hi,
sorry for my bad english, especially when you want to get information in such a complex thing it is hard sometimes, I'm checking out the weight of bullets for some time now. Most goes back to World War 2 when machine guns or "machine cannon" like we would call everything with 20mm or more today where the only weapon in most cases. I know there have been some unguided rockets on german and I'm sure on allied side too, but the bomber crews had crazy amounts of MG, I think the B-24 was flying with 10 Browning M2 Guns (in use until today called "fifty" I think? 0.50 inch, 12.7x99mm), some crews if they expected "big trouble" took even 12 or up to 14 I have read. 
I don't know if it true or if you find enough holes to fire 12 or 14 machine guns. The Browning M2 has an empty weight of 38.14 kg. That is the reason why in Vietnam the soldier who had the very hard job to carry the weapon for a few miles never had the amunition and I think he didn't take other things, carry over 38kg and maybe run with it is hard enough, there were at least 2 guys they were close to him and they had belts with 50 or 100 (don't know) bullets for the weapon, I think many people see pics and think this was kind of "rambo" or to be cool, but they don't know that a soldier alone wasn't able to carry the Browning M2 and 100 bullets,
now we got rockets everywhere in the air fight, I think even the modern "birds" got one machine cannon with a few rounds (150-300), but only on helicopters MG's remain extreme important. 
In the article there is the information:
The complete installation, which includes a double-ended feed system that returns empty cartridges to the magazine, weighs 900 lb (410 kg) empty and 1,230 lb (560 kg) loaded.
In the article is also mentioned that this is for 300 rounds. Making 150kg for 300 rounds, so 500 gramm per round is correct?! I found on another website the information for 5 types of 25mm amunition that can be used for the M242 MG:
Projectile Weight 
4.73 oz (134 g)
6.53 oz (185 g)
6.42 oz (182 g)
3.35 oz (95 g)
3.39 oz (96 g)
Cartridge Weight
16.15 oz (458 g)
17.67 oz (501 g)
17.67 oz (501 g)
14.81 oz (420 g)
16.01 oz (454 g)
Can someone explain this?! So if this gun fires 1 round only (lets take the heaviest projectile from above) 185g from the 458g "leave" the system?! Since empty cartridges are returned into a magazine? Or how much is the weight of the round when it leaves the gun?! Greetings Kilon22 (talk) 05:56, 5 May 2013 (UTC)
replies: text: Indented line
The 185g projectile leaves the gun down the barrel along with some propellant gas mass, and the remainder of the 458g cartridge weight (minus projectile weight and minus propellant weight) is cycled through into the ammunition stowage.
The "empty" figure will refer to a completely unloaded system - upon returning to base, as the ammunition is restocked, the spent cartridges will also be removed from the pod.81.101.221.187 (talk) 02:07, 20 December 2013 (UTC)
thread_title:  Weight 

message: The GAU-22 is claimed in the article to have an accuracy of 1.4 miliradians.
This is not strictly correct, and the source provided has since expired.
According to the manufacturer (the site originally sourced before some company change), it does achieve 1.4 miliradians - but only over a "1-sigma radius" - this is approximate to the accuracy of forty percent (39.7%) of rounds fired. Whilst theoretically a good indicator of the performance of the gun, it should be more proper to use the 80% accuracy figure cited by the manufacturer of 5 miliradians, either in place of or alongside the quoted 1.4mr figure.
This 5mr figure for 80% of rounds is identical to the GAU-12 from which the GAU-22 derives, and also the GAU-8 30mm gun.
