It seemed, however, that although a 356mm caliber would be a new measure of destructiveness, it would also make obsolete about every ship yet build, including the Navy's new Utah class now being build.  
Alas, calculations revealed the 14" gun to be more effective than even the currently build 12" L/50, and the gun was adapted for the second-next class to be build, the New Yorks. Arkansas and Wyoming would retain the 305mm gun and add another turret for a total of twelve such weapons as opposed to Utah's ten.

    The 14" L/45 was mounted on New York and Texas, Nevada and Oklahoma, and Pennsylvania and Arizona.  
Some difficulties were apparently encountered as the L/50 gun is said to have "remedied the serious constructional defects of the first 14"...", but there is no indication just what these difficulties may have been -- any information will be much appreciated.

    All guns per turret were fitted in one cradle, causing problems in case of damaging hits to one gun. However, this was mere theory - in combat, no such damage was encountered.
