Didnt the soviets also have a 90 degree max angle cruiser? :P

50 degree max angle.

Real Life =/= NF

@Storm: Hm, all sources I've read indicate the Iowa 16"/50 had max angle of 45.

Apparently angle for max range shifts from gun to gun. On the ones you are thinking about
van (USN 5''/54?) 55 degrees is both the max range AND the start of HA. HA is pretty much
defined as using the higher angle of a pair that gives you the same range, and as range
goes back at angles higher than the max range, that one marks the start of HA.

Kind of. It totally depends on the gun.

In real life, wind resistance in a humidity saturated environment does make some
angles other than 45 degrees more optimal for some guns, as previously stated.
But NF isn't real life.

Also in real life, the Iowas guns were built with a max angle of 40 degrees. I think i
read once that 43 degrees was their maximal firing range, but that the designers
weren't too concerned with it since that would be firing over the horizon and
accuracy could not be attained anyway with 1940's technology. They could have
retrofitted them later for a few degrees more, but the expense wouldn't have been
warranted for an extra few hundred yards, not when missiles were the law of the
day.

In game I think the max angle is approximately 55 degrees... or am I getting that
confused with that being the start to HA?

@Eradicator
The optimal angle for max range in an enviroment with a real damp coefficient (air
resistance) is less than 45 degrees. Intuitively the longer the proyectiles is in air, the
more slowness it gets, so you want it to take the slowest time to get into target (ie:
angle less than 45).

It doesn't hold in game because of korean physics.

In a frictionless environment, 45 would be, but because of air resistance, shells end up
slowing down, thus making higher than 45 more optimal for range
