- #
- #The GAU-8 Avenger used on the A-10 uses a special 30mm DU penetrator, on top of
- #a relatively enormous (roughly the size of a milk bottle) cartridge. The
- #A-10 is the only platform to carry the Avenger cannon.

- #The 30mm Hughes chain gun carried by the Apache uses the NATO standard 30mm

- #ADEN, I believe. British Harriers carry 30mm cannon chambered for this round,
- #and the Scimitar light tank uses the same round in its 30mm cannon. Going way

- You were doing fine until you mentioned the Scimitar and Fox :)
-
- The GAU-8 uses a large bottlenecked 173mm long cartridge case. As used in
- the A-10, three natures of ammunition are available: full-bore AP with
- DU core, HE (these may be API and HEI; I don't remember), and TP.
-
- When used in the Goalkeeper CIWS, the GAU-8 fires a tungsten penetrator
- MPDS ("missile piercing discarding sabot" - I didn't make that up) round.
-
- The 30mm Chain Gun used in the AH-64 uses ammunition based on the Aden/DEFA
- family. This uses a very short cylindrical case. The service round used
- with the Chain Gun is HEDP - High Explosive Dual Purpose, with a fluted
- cone copper SC liner and a prefragmented steel body.
-
- The Scimitar and Fox use the 30mm Rarden gun, whose ammunition is based
- on an Oerlikon 30mm round (KCB?) more powerful than the Aden/DEFA but
- not quite as good as the 30x173 of the GAU-8.
