Why British Army's new CT40 cannon is so advanced

Looks like you can't put them in backwards. They physically won't locate or go into the carousel as there is a locator groove at the rear of the cartridge if you try and put them in the wrong way.

My issue with this is that I see at least two failure points, both involving the ammo line up system, after the chamber rotates back, is there a hard stop to ensure proper lining of the chamber and also after firing does it line up again? Are there switches that ensure that they are lined up before another round is attempted to load in and if they fail can a manual over ride be used?

[@ivancho5854]

​@TurnipstalkNot 20, OVER 25! I suspect that they have had and probably still have reliability issues.

[@jamcguire100]

So every single round you load, you have to open a metal drawer, insert the round, and close the drawer again, and rinse and repeat? And that's the most efficient way you could come up with to rearm the system? Wow. Even the rotating chamber in the middle doesn't strike me as particularly ingenius, it strikes me as likely to seize during prolonged use in a dirty battlefield the like of which we're witnessing today. Why not just use the shape of the round to your advantage and have a fixed port and a trapdoor, theres got to be considerably less surface area on a door than a full rotating body assembly?

[@DailyFrankPeter]

1:14 holy cow... how do you gas-tighten that?

[@rustknuckleirongut8107]

Sure this sticks less into the cabin, but do you really gain any interior space when you still need to accommodate a huge ammo loading and storage system just in a different location. I am kind of failing to see the massive problem this solved or what the advantage is here. Is this gun that much cheaper to produce that it warrants the use of this over existing 40mm guns? Is a few degrees of elevation on the gun the only real benefit here? (Edit: Read up on this some more and wow. This was 30 years of embracing avoidable problems until they were things that required major redesigns(Like did no one even think that hanging a three ton loading system up to a meter off the centerline of the turret might cause some balance issues for the turret and cause the gyros that are trying to stabilize the gun to go nuts). When the Americans tested it they found the recoil impulse was so sharp that if would sometimes cause the firing control system to shut down. Also when you fired the last round in the magazine it could get stuck in the breach and there was no way to remove it from inside the vehicle. They also lost almost all the initial customers meaning projected ammunition cost skyrocketed to the point where it would be cheaper to bribe the enemy into going home then firing)
