25mm GAU7 F15


Reported as a GAU 7 for the F15. Does anyone have a good decription of how this differs from the GAU7a?


Does GAU stand for anything? Also PGU with the 30 MM’s?


Gun Aircraft Unit and Projectile Gun Unit, IIRC.


Thanks so much Tony! I always wondered what it stood for. I have a few 30’s with PGU on them and was curious. Appreciate your help.
