Metal Storm has its own problems.2: Metal Storm- Metal Storm is one of the greatest revolutions in firearms technology. The stacked bullets in the barrel allow for a ridiculously high fire rate. This would be a perfect Close-in Weapons System.
- As a projectile system it is extremely short ranged, which is why so many navies are moving from guns (CIWS) to missiles (RAM).
- Next there is the weight issue. Metal Storm systems are lighter than guns with magazines for a few rounds, but as the ammunition supply increases you quickly reach a point where a conventional autocannon is lighter. This is important because it effects the size of the mount and the slew rates for aiming negatively for the CIWS role.
- Recoil is the final issue. Force due to recoil on the mount is (the recoil per round) x (the rate of fire) x (Factor for recoil reduction/control). Obviously the higher rate of fire puts a higher load on the mount, but Metal Storm also appears to be incompatible with all recoil control technologies. This means the mount has to be even more massive, less responsive, and unsuitable for the role.
Right, a few thousand tons of highly toxic volatile halogen based chemicals being run through a hot complex apparatus sealed inside a box with your crew. If an attack ever penetrates the fuel storage your only option may be to immediately abandon the ship until decontaminated. Yes, the stuff is THAT NASTY.3: Lasers- While Metal Storm would be fantastic as a CIWS, I believe it would be a secondary level system. The main system, I believe, would be chemically powered lasers that would be, theoretically, capable of destroying incoming threats as far away as it could see.
Get with the program and use either free electron or solid state lasers.
