This Marine wholeheartedly agrees. The abandonment of modern ballistic efficiency and modern propellants in pursuit of a very long range naval gun was to sentence every engagement outside of CIWS range to require expenditure of very limited and very expensive missiles.

Minor semantic point; it's not "two gun batteries" so much as a "two-gun battery" (or a "three-gun battery"). Your battery is all of your weapons of a certain type.

As an old Gun Boss, I gotta say we've lost considerable capability gunnery-wise since the Mk 42's went out. The Mk 42 had redundant systems, the Mk 45 is a one-trick pony. Any single component of the Mk 45 goes down and the gun's down. With the Mk 42 you have two of nearly everything; e.g. one hoist goes down, you have another. Of course that's why the Mk 45 weighs about half of the Mk 42. Mk 45's barrel is much thinner too; you're pretty much in "hot gun" territory as soon's you've let your first round go.
