Well, for one, I'd assume that the requested security level of Prime Asset would mean that they upgraded to less shitty munition than DU/tracer mix. HE might be currently used but I'd personally go for modern solution of timed fuse fragmentation/flechette ammo as it greatly increases the chances of hit. The timed fuse is set as the projectile leaves the barrel, using data provided by the targeting system and known velocity of the bullet.
Well, there's now AEGIS Ashore too...
The problem with that is that, yes, you
will likely hit, but that the particles may/will probably not be large enough to do enough
effective damage. Small holes, yes, which sufficient - supersonic - speeds may allow the airframe to tear and distort enough to divert the airframe, but not necessarily enough to mission/total kill the airframe in enough time to be ineffective in its purpose. Other than the awkwardness of the setup, this is one of the reasons that the X-25 "smart grenade" failed to find mainstream use in the Army - it didn't do
enough damage on average to justify the expense of using it.
There is, on the other hand, a public news story in which a CIWS accidentally left in auto-defense buzz-sawed the wing of a friendly aircraft that was not transmitting the proper IFF. The HE rounds might have had a similar effect overall, over a greater area, but may not have had the penetration to actually
kill the airframe.
The primary alternate to DU rounds, that is actually in the inventory for ready distribution, is Tungsten penetrators. I'm not sure, but I suspect that, due to industrial processes creating a demand for Tungsten
other than the government, the DU rounds are ironically less expensive.
This. I thought it was fairly obvious which version the omake was referring to.
Not sure about that. The CIWS system that I know of that has such capability is the Rheinmetall Oerlikon Millennium Gun(well, that's the full official name). It uses 35mil rounds (AHEAD) with a programmable magnetic fuse (uses magnetism to program each round, not as the actual fusing signal). I'm not sure you can do the same for 20 mil rounds that the Phalanx system uses.
That's the initial problem, it was obvious. The combination of terminology used indicated the Naval version/supply line even if the two versions are effectively the same in any other respect. As to the Aegis
Weapon System, with the exception of the RDT&E setups, there are NO shore versions and it has very little, other than a higher resolution radar/targeting feed, to do with CIWS such that the CIWS mount would be even more effective, and maybe less obvious, with a more dedicated system (which it technically already has with the integral radar/targeting system). The smallest synthetic aperture radar panel associated with the AWS system to fulfill the purpose intended is still larger than man-size and requires a significant mounting pedestal that would draw even more
unusual attention to it being installed.
I believe that this is getting into
significant derail territory and should be brought to an end.
