Did anyone consider putting a battleship's entire main battery aft?
Short answerYes, the US Navy considered it but rejected it; the aim was the same concentration and displacement economy as an all-forward battery.
NotesThe US Navy examined an all-aft main battery but did not adopt it. The study shows that concentrating every main turret at one end was not unique to the Royal Navy's Nelson-class solution. Both the all-aft proposal and Nelson's all-forward arrangement pursued the same design logic. Concentrating the battery allowed designers to extract more fighting power from a limited hull size and displacement.
