Aircraft weapons

Oh, without a doubt, I'm just saying that if you change one thing you might end up being compelled to change another.

I had a Maverick kill two tanks in different hexes, so this is a problem. But why can't the A-10's 30mm gun kill a tank? After all was'nt the gun was designed to do this? At least once on occation?

[DRG]

Two kills for one missile can happen. If the HEkill is reduced that reduces incidents like that but also makes the weapon less effective against non armoured targets. We made changes to the code in the last release that reduced the number of incidences like that and I assume this isn't something you see all the time but you don't say one way or the other. If it is, nobody else is reporting it.

The A-10's 30mm gun CAN kill a tank in the game. I have seen it happen so saying it cannot "At least once on occasion" is ridiculous and I can provide save games that prove that statement is ridiculous. However, we are reviewing how multibarreled weapons are handled in the game and found a flaw in the code that goes back to SP2 that was reducing the effects of multibarreled guns. That doesn't affect the way the A10's are set up in the OOB's you have now but will when the patch is released and the new OOB's are used. However, don't expect fantasy results where A-10's leave masses of twisted wreckage after one pass. The actual armoured piecing ability of the GAU-8 Avenger is 69mm at 500 meters but the game fires from a shorter range and is rated as a 9 right now and that's won't kill a lot of tanks.

DRG,

The two kills with on shot has only happened twice in three test runs of a 1992 scenario {US vs Iraq} with the Iraqis having over 200 tanks. So this as you said is not common.

The A-10 30mm has yet to make a kill on a tank. It will kill most everything else but no tanks yet.

I am asumeing that the 69mm pen figure for the gun is with normal AP. I belive that this weapon also has a DU round for it. If Im wrong then we all know what asume stands for!

[DRG]

The only AP round made for the AN/GAU-8 Avenger 30mm gun system is the PGU-14/B Armor Piercing Incendiary (API). That's the DU round. There is no "normal" AP made and the penetration for that round is reported in many places as being between 65-70 mm at 500 yards. As I said, we boosted it up a bit because attacks in the game happen at closer ranges than 500m so it was given a tweak upwards that it may not actually deserve.

Here's one source for the guns penetrative abilities....GAU-8 Avenger

there are others

If you want to see an A10 light up a tank pick a target with less than 9 rear armour and attack from the rear. Most gulf war 1 Iraqi tanks qualify.

It's not a wonder weapon but it does have the mystique of one.

However, if I'm wrong I'm sure someone will correct me

DRG,

Tried to tweek the A-10 with some results as far as the gun goes without adding PEN. As you said in an earlier post it may be how the game handles multi-barreled weapons on aircraft. I'm glad your working on it.

Now you can look at a site that I found that explains the newer upgrades that will make the A-10 even deadlier and stretch its service life to 2028.

http://www.airforce-technology.com/projects/a-10/

On this site you will see a statement as follows,

"Using the cannon, the A-10 is capable of disabling a main battle tankfrom a range of over 6,500m."

You will also find that there are two AP rounds for the gun that are both refered to as API (Armor Piercing Incendiary).
One is DU, the other is not. I suspected this because as far as I know the Pen capability of DU rounds is classified as is a ton of other stuff that your trying to portray in this game. I do not envy your job.

The 25mm on the USMC's Harrier jet also fires DU rounds but to a much lesser extent.

That's another story.

DRG, on the same site as above you can click on Industry Projects on the top left and find other info on many other aircraft and helos that may be useful.

Interesting they don't specify or offer examples of which "main battle tank" they are "disabling" from 6.5km away or how they calculate what "disabled" means. You could pepper a T55 from 6.5km away and have the crew panic and abandon the tank and that would make it tactically "disabled"

As for ammo, there are ample number of sources that say there are TWO combat rounds that cannon fires. The PGU-13/B HEI High Explosive Incendiary round and the The PGU-14/B API Armor Piercing Incendiary round . The only other round made for that gun is the PGU-15/B TP Target Practice projectile and is used for pilot training so there is one, and only one "AP" round made for that weapon. The API round IS the DU round. DU is a natural pyrophoric material which enhances the incendiary effects


I don't normally like to quote from Wikipedia but this quote sums things up quite well

http://en.wikipedia.org/wiki/GAU-8_Avenger
"The standard ammunition mixture for anti-armor use is a four-to-one mix of PGU-14/B Armor-Piercing Incendiary (API), with a projectile weight of about 15.0 oz (425 grams or 6,560 grains) and PGU-13/B High Explosive Incendiary (HEI) rounds, with a projectile weight of about 12.7 oz (360 grams). The PGU-14/B round incorporates a depleted uranium penetrator."

this matches the info provided by this website
http://www.hill.af.mil/library/facts...et.asp?id=5741

"The General Electric-built GAU-8/A 30mm Avenger gun system could hold up to 1,174 rounds and could fire aluminum-cased ammunition with either armor piercing incendiary, high-explosive incendiary, or training practice rounds. "

and others

Note what this website gives under specifications for that weapon
http://www.fas.org/man/dod-101/sys/ac/equip/gau-8.htm

Armor penetration 69mm at 500 meters /38mm at 1000 meters

that is typical of the info available on that weapon.


also look at
http://www.globalsecurity.org/milita...tems/gau-8.htm

All in all it's difficult to make assumptions about a weapon based on a vague statement that "is capable of disabling a main battle tank from a range of over 6,500m" without knowing what they mean by "disabled". There is no evidence the GAU-8 will leave a main battle tank a smoking ruin from 6.5 km range but then....... which "main battle tank" are we taking about ? A T55, A Leo 2 ? A T-90 ? The only real "targets" the A-10 has had to deal with have never been anything even approaching "top of the line" MBT's that I'm aware of but they WILL knock out UK Scimitars in real life but they will in the game as well as any test game will demonstrate.

This School of Advanced Air and Space Studies thesis..

shows a photo of a "Serbian T-55 Destroyed by A-10 with AGM-65 Maverick" Now why use a $150,000 missle to destroy and old T-55 if the Gau-8 is such an efficient tank killer?
