The Iowas' bow also rises up a fair bit (sorry, not sure what the correct nautical term is). If she fired her forward turrets at 0 degree elevation, she'd shoot the top of it off.

Compare to the bow for a KGV which IIRC had some sort of requirement to be able to fire her guns at low elevation over the bow.

The compromise made them wet ships forward though and the RN adopted a different design with Vanguard.

Googling the Q of forward firing BB guns, I found discussions but few conclusions.

 

Then there is this: go to 8:00 --

Indicated that the blast of both turrets of the Iowa class firing forward was considered likely to strip the forecastle of practically all material, including the anchor chains, capstans and so forth.

 

Further discussions but without much authority: https://www.reddit.com/r/WorldOfWarships/comments/54lyrt/til_battleships_cant_fire_bow_on/

 

One needs to have someone such as Bill Jurens' opinion or statement on this, but I don't find it, viz. http://www.navweaps.com/index_inro/INRO_BB-Gunnery.php

Sorry, no citations beyond "it's probably in DK Brown's BB development series somewhere", but there were restrictions on arcs to be used for peacetine firings of RN guns, although my recollection of this is that the main concern was damage to the psint, deck and fixtures, rather than overall ship integrity.

I'd be intrigued about the relative shape and magnitude of transmitted recoil forces versus slamming into a wave at 30knots...

Nothing in Friedman's US Battleships either. The French Battleships 1922-1956 shows that their quad turrets were considered effectively as two half turrets and the right and left pairs were fired alternating although dispersion was unsatisfactory because of the shells being too close together when fired that way.

DK mentioned in his books that superfiring turrets were not like in the pre-WW1 RN due to blast from the superior turret damaging the rangefinders and incapacitating personnel in the lower one and IIRC Rodney damaged itself firing at Bismarck over the bow,

If Iowa class museum docents are putting it out, there must be something written up. The longitudinal problem for the Iowas might stem from the sheer as well as narrow beam of the hull forward of the first turret barbette, placing loads on the ship not experienced by the shorter hull BBs.

Captain O'Connor was KIA when his first command, HMS Neptune, ran into a minefield in December 1941 and went down with exactly one survivor.

 

Interestingly another case where an enemy was chased at not insubstantial although calculated risk. A number of survivors apparently went into the boats, but only one was left when he was picked up by the Italians six days later.

Board of Inquiry and picture of O'Conor (sic!) here:

Sobering read.

 

All the best
