From: Amos Shapira <amoss%BATATA.BITNET@CUNYVM.CUNY.EDU> There were a number of references to the GAU-8 cannon in the conference. All of these mention the weight and the speed of the round, its penetrative abilities and its construction. NOt one message mentioned a report I read (can't remember where... some Bill Gunston booklet) that the standard GAU-8 burst is only 30-50 rounds. The recoil of the gun makes longer bursts inaccurate, as it swings the plane out of alignment. Despite this, the kill probability is very high. Since DU rounds are porphyric, a hit on a tank will probably do horrendous damage. Can anyone substantiate this report? Marc A.

The A-10's nosegear is off-center, precisely so that the gun can be located exactly on the centerline. Henry Spencer at U of Toronto Zoology uunet!attcan!utzoo!henry henry@zoo.toronto.edu

Two mechanisms come to mind: 1) Depending on the stores (fuel, ammo, missles) loaded the geometric centerline may not go through the center of mass. 2) The thrust from firing the gun slows the plane, resulting in a change of attitude (or altitude, take your pick).. -- Steve Nuchia South Coast Computing Services uunet!nuchat!steve POB 270249 Houston, Texas 77277 (713) 964 2462 Consultation & Systems, Support for PD Software.

From: Frank Dunn <frank0@ibmpcug.co.uk> During flight testing the A-10 did have problems with bore sighting when the gun was fired. If you look head on to an A-10 the gun in fact is not 100% in line, its off a degree or so - the figure of 6 pops into mind. The recoil slows the 'plane down and also tends to slew the barrel and thus the 'plane. The burst limitation sounds correct. -- Automatic Disclaimer: The views expressed above are those of the author alone and may not represent the views of the IBM PC User Group.
