It's so tough to keep up with this thread, subah log aaram se armour thickness pe ladte hain aur pata nai achanak se dopahar hote hote saale CIWS pe ladne lagte hain
Anyways
@Blood+ @Aniruddha Mulay @SwordOfDarkness @Fatalis @ezsasa @binayak95 here's few points
- as for fast firing small calibre vs slow firing high calibre thing is concerned; always go for slow firing high calibre; like 40mm l/70 in this case. Why? Because a single air-bursting round of 40mm can deal the same damage as multiple HE rounds of 30mm. The best gun based CIWS currently available is Oerlikon's AHEAD air-burst rounds, coz despite being only 35mm calibre it covers a much bigger area than HE ones.
Furthermore, a 40mm shell has bigger volume so you can add things like proximity fuze or may be guidance system in future and still retain sufficient space for HE warhead. In case of smaller calibre, things are not that easy. Remember the air-bursting XM-25? Because of adding all the electronic systems in that 25mm shell the explosive got reduced; ultimately making it under-powered.
- Now coming to C-RAM vs our very own C-Tanki. The AK-630 is a pretty self contained system; it only draws electricity, water for cooling, pneumatic - hydraulics lines and signal from radar...all the other things are built into it. And not just other things, but most importantly; Soviet era old and bulky other things.
We could have easily made something way better than us Phalanx based C-RAM; coz remember 30mm>20mm. We could have slowed it down to 3,000 RPM and removed the whole water based barrel cooling system, newer SMD based electronic in place of old tubes, electromechanical drives in place of hydro-pneumatic...and perhaps most important, ammunition management. Ever wondered why that AK-630 module looks so humongous? We'll because it's hollow inside so that empty shells can be dumped inside it, someone can enter to remove them and obviously someone can enter to load the ammo. But these are not required in a land based system; you can easily dump empty shells in the open as you don't have the hazard of any FOD damage like in ships.
But even this little common sense was way too much for our engineers and they simply put it as it is.
- Sudarshan is good but not so good. Just look at an ordinary l/70 Bofors and think what'll happen if you cover it with big plates...it will look like Sudarshan. If your objective is to make a ISIS level makeshift CIWS then it's fine, but something more then there's few problems. Ammo handling and capacity will always be low, traverse and elevations will be sub-par coz you simply replaced old drives with motors, automation would be low
