GCV Infantry Fighting Vehicle

I wonder why they jump right from the 30mm to the 50mm SuperShot? No consideration towards the 40mm SuperShot, conventional 35mm, or 40mm CTA?
 
beleive in Janes IDR there was also a 55mm Supershot proposed, but yes each rd would take up quite a bit of space.
 
Actually, isn't the supershot round the same length and width but without the taper?
It might displace more air, but I don't think it's going to cut down on ammo capacity to any real degree.


I do have a question about the supershot.
In addition to the ADFSDS round, is there a full caliber explosive round for this weapon? Without one it would seem to be a one trick pony that's less versatile than the 35mm it replaces.
 
There is a 50mm Programmable Airbursting Munition round (a scaled-up AHEAD) as well as the sabot. I've not seen a pure HE round, but it's hard to imagine that one would not be made.

I believe the EAPS round evolved to use a larger chamber than the baseline 50mm Supershot. If so, it wouldn't be compatible with the baseline Bushmaster III. If I'm reading the link below correctly, the EAPS test rig combines parts from Bushmaster III and IV.

Interesting. The earlier presentations depicted a notional "production" EAPS cartridge that was shorter and narrower than both the "optimized" and "workhorse" cartridges shown in the above preso.

Looking at the dimensions for 50mm Supershot, EAPS would have to lose about 6 inches in overall cartridge length to stay within the 50mm Bushmaster III confines.

The attached presentation (from May 2014) mentions an upgrade path to 40mm SuperShot for the XM813.

Thank you TomS for posting the link, but to remain contrarian, one would have to point out that the highest velocity before diminishing returns occurs appears to be the 60mm according to the presentation.

Yeah, just as "rebuild" as some helicopters.

"More horsepower. Higher suspension. A blast-resistant underbody. Safer fuel tanks. A larger hull."

Basically they build an entire new hull with all new insides, and slap the old turret on.
