the Bureau of Ordnance assumed the Iowa class would use the 16"/50 Mark 2 guns constructed for the 1920 South Dakota-class battleships.
lighter, more compact 16"/50 and designed the ships with barbettes too small to accommodate a 16"/50 Mark 2 triple turret.
The new 16"/50 Mark 7 was designed to resolve this conflict.
Super-heavy shell
The Mark 7 gun was originally intended to fire the relatively light 2,240-pound (1,016 kg) Mark 5 armor-piercing shell.
However, the shell-handling system for these guns was redesigned to use the "super-heavy" 2,700-pound (1225 kg) APC (Armor Piercing, Capped)
The North Carolina and South Dakota classes used the preceding 16"/45 caliber Mark 6 gun, which could fire the 2,700-pound shell.
Only the Yamato-class super dreadnoughts could throw more weight.
>>677 ＞要塞砲はMk7じゃなくて、Mk2と書いてあるようだが？
1925年以降で 16"/50 Mark 2 guns 配備。
よく見たら Super-heavy shell の事も書いてあった（＝射程距離が下がることはない）。
Yamato-class に関してもねｗ
>>678 ＞そもそも最大射程にどれほどの意味があるのか
停船した大和が交叉着弾の後、米軍要塞砲の攻撃を一切受けず一方的に9発/30分毎の飽和砲撃をできるって事実のみｗ
つまり、航空戦力に一切頼らずに全てのハワイ要塞砲を撃破できるって意味があるのよｗｗｗ♪
