Thanks Greg, I've seen those photos before (research for a project I'm building), but all they are showing are the breach and loading mechanism, not the ammo storage system. The ammo is contained in the rear area of the pod.

On the SUU-19 and SUU-23 20mm Gatling Gun/Cannon pods the ammunition is carried in a drum that is very much like that used on the F-4E/F-4F Phantom II and the F-105 Thunderchief and the larger GAU-8 gun fitted to the A-10 Thunderbolt that has a capacity of 1350 rounds of 30mm.  All of these retain spent rounds after firing.

That's interesting Jeff, I've read that the A-10's GAU-8 only had 900 rounds ---

How did they get the drum into the SUU-23 ? It doesn't look big enough in diameter.

Not the same size ammunition drum as that used on the F-4E/F-4F and F-105.  Similar but not the same size drum magazine is also used with the M61 mounted on the F-16 and F-18. 

As far as the ammunition capacity goes for the GAU-8 as installed in the A-10 I was correct, but there is a clarification to that number:
Quote
GAU-8/A Avenger rotary cannon with 1,174 rounds (capacity 1,350 rounds)
.  As for why the difference, I have no answer but that number (1350 rounds) has been the number given in many reference books on the A-10 aircraft and GAU-8 weapon.  The capacity will vary for each mission so 900 rounds for a typical sortie may be due to fuel and range constraints after all you do not need to carry a full load of fuel or weapons for every mission.  All of that is determined by the Air Tasking Order and the people that are tasked with flying the mission.

I think you will find it will fit...just:




As for reloading:

Hmm, it looks like the outer shell of the pod at the rear is also the outer shell of the drum. Now that explains a lot --- thanks Greg.

The rounds on the GAU-8 and the M-61 area also arranged as a helical spiral with the rounds arranged radially, point in. That arrangement isn't gonna work on a 57mm or 75mm round unless you want a 5 or 6 foot diameter pod. They are gonna have to be arranged along the same axis of the gun, limiting the ability to store a lot of ammo unless there is another mechanism that advances ammo from a rear carousel to the front one, not impossible, just more complicated and probably requiring additional power to drive it versus using just gun recoil.

I figured they were probably Soviet, they have that "Oh, yeah? You've got rotary cannon pods? Well, we've got this triple rotary cannon pod, so there!" vibe, but it's always good to get more detail.

Thanks, mate! :smiley:

Oh, your helicopter has a gun...that's cute:




Actually the GUV-8700 comes in two options:

1x 30mm grenade launcher AP-30 Plamya - AGS-17  (9-A-669, or 9-A-800) - 300 rounds or
1x 4barrel minigun YAkB 12,7mm + 2 x 4barrel minigun GShG 7,62mm  (9-A-624) 750rds for 12,7 and 2x 1700 rds for 7,62
