    Montana Class BB

    My question is what were the major improvements over the Iowa Class that the Montana Class would have brought to the table?

    I know she would have had an extra turrent and would not have been able to transit the Panama Canal.

    What would have been the inovations to make this class stand above the rest?

    Her most significant improvement was protection -- rated to withstand the 2700# 16" AP projectile fired by her own guns, the Iowas and South Dakota's were protected against the earlier 2250# projectiles. Since the Yamato's 18.1" projectiles did not perform significantly better than the US 2700# AP, they probably would have had adequate protection against those guns

    Yep, pretty much it. Also the Montana's represented the fact that the Iowa's were infact a departure from traditional US BB design. Our design philosphy valued firepower and protection over that of speed. That being said our "fast" BB's of the 30's were still slower than the contemparary BB's of other nations. The 10,000 tons that the cancellation of the Washinton Naval Treaty bought the Iowas about 5 knots in speed, an extra 5 calibres on the main guns, and tiny bit more protection over that of the South Dakotas. The Montana's on the other hand had more firepower and protection but at the cost of those 5 knots and about an additional 10,000 tons.

    The Montana's were also to be fitted with 5"/54's a fine upgrade over the 5"/38's of the Iowa's.

    Navweaps had an interesting comment about the new piece:

    This gun was not as popular as the 5"/38 (12.7 cm) Mark 12, possibly because the larger projectile and cartridge cases resulted in faster crew fatigue.

    Essentially, this weapon was simply a longer version of the 5"/38 (12.7 cm) Mark 12

    I guess they would need more Marine 5" gun crews.

    Marines only manned few mounts aboard the Iowas. You wouldnt need more men just faster change out cycles of the gun crews if necessary. In most cases it wasnt, the ones that would be changed out would be in the mags loading powder and projectile. Not the ones in the upper handling rooms or the mount proper since they sealed when in action.

    Figure the 5"/54 rifle would be 6.7' feet longer then the standard 5"/38 rifle which was approx 15.8 feet long so the new rifle would be 22.5 feet long and weigh almost 3000 lbs each perhaps slightly heavier. Which also means the projectile would be slightly longer, weigh slightly more then the standard 55lbs and require a heavier powder charge to achieve longer range. The Sky radar sets would have to be upgraded from the Mk 38 and its mating radars as well.

    No doubt, had the USN built them, FCR would have taken another step forward from the Iowas as well as their standard radars, protection. Perhaps new boiler and water treatment designs among other improvements in propulsion and power. They would have needed heavier anchors and a lot more paint as well.)

    I'm certainly no naval expert but, IMHO, the Iowa's represented probably the best combination of speed, firepower & armor in the world. Sure, the Montana probably could've shrugged off hits from the Yamato's 18" guns, but how often would that have happened? For protection against one (numerically small) class of battleships, you're losing at least 5 knots of speed, maybe more. Not worth it.

    Yes the did beyond doubt. But although you loose 5-8 knots of speed you do gain 3 more 16"/50's. A tough trade considering.

    Especially considering the only BB's that outgun you can't outrun you.
