Iowa had 220m dispersion at max range.
During Gulf One, but not at any timeframe covered by this game.
In combat conditions during early 1944, at 35000 yards
Iowa's dispersion was well over a half-mile. This compares favorably to reported dispersions of the Center Force against
Gambier Bay and to
Hiei against
USS Edsall. At 25000 yards dispersion was expected to be small enough to obtain a first-salvo hit against a battleship, but probably not with multiple shells.
Normally, a battleship secondaries don't have **** for range, damage and accuracy and no DD would survive coming close to a BB either.
Scharnhorst's last battle, the British destroyer attacks on
Bismarck. And these are against ships that have fairly modern secondary batteries. A ship with casemate mounts, simple and unstabilized?
Laffey vs.
Hiei and
Hoel vs.
Kongo both provide instructive examples where destroyers literally approached so close the casemates couldn't depress to hit them. The second of those happened
in broad daylight.
tl;dr: You're wrong and you don't know what you're talking about.
