The Oto Melara's muzzle velocity is only 915 m/s, the next wave of hypersonic missiles and glide vehicles all have speeds of at least Mach 5 (1715 m/s) by the most pessimistic analyses.
Intercepting at range isn't happening.
915m/s will be the standard HE round. The DART is a sub calibre round with a muzzle velocity of 1,100m/s
1,100m/s is similar to most CIWS rounds.
So if the DART projo is considered too slow, then so would almost all CIWS?
I will trust the Leonardo and similar companies assessments and conclusions on this once they have tested their theory against supersonic and hypersonic targets for real (as in life fire tests and trials, not war, at a minimum)
I for one think it’s noteworthy that the only two countries in the world who actually have supersonic AShMs and the technical base to develop their own CIWS have both gone with insane RPM designs as their principle gun based CIWS.
The DART/STRALES was tested in 2014 against supersonic targets. No they don't operate Supersonic AShM but they have had access to supersonic target drones since the 1960s. Target drones that simulate sea skimmers at M2.5+ and diving ballistic targets at M4~5
I hope that's good enough for you?
My 2c is that CIWS are the low hanging fruits, easy and effective tech that is quick to push out. If we take the USN as an example, projectile based CIWS predated missile based short ranged anti-missile defenses. First comes the CIWS then the RAM.
My take on the DART/STRALES, it is not actually similar to the projectile spitting CIWS but is more akin to a RAM system. The DART is really a CLOS guided missile that is post rocket burn out. Okay, the kinematics aren't quite as good as a missile but if it walks like a missile, talks like a missile, it is a missile.
Yes, having smart rounds would be useful to push out the engagement range compared to dedicated 30mm, but why not have both? All modern Chinese warships’ main gun have secondary AA functionality. Hell, why not also have a missile based CIWS? Which is precisely what all top end modern Chinese surface warships are doing.
I agree.
If you have a main gun, budget allowing, why not dual purpose it? 2 systems engaging an incoming target can only increase your PKill right?
If you have space on the platform, I'd say go for all 3 - missile based, guided main gun, unguided CIWS. The more layers you have to your AD onion, the more you're gonna make your opponent tear up trying to peel it.
