superfiring

In addition, York also had a very tall bridge designed to clear the aircraft catapult originally planned to be carried on the superfiring ('B') gun turret forward.

The guns in all three turrets could elevate to 45 degrees, but only I and III turrets could depress to 2 degrees; the superfiring II turret was not able to depress.

The original design of the Lexington class called for ten 14"/50 caliber guns of either the Mark 4, 5, or 6 variety to be mounted in four turrets (two triple superfiring over two double turrets) for the main armament.

The Parker class leader of 1915 had introduced a raised shelter deck forwards, allowing two guns to be carried in the classic superfiring (i.e. one gun fires over the top of the one below and in front of it) "A" and "B" positions.

"X" was placed on the quarterdeck immediately aft of the after superstructure, at the same level as "A" turret; "Y" was immediately aft of "X" and at maindeck level, allowing superfiring of "X" over "Y".

In their original 1916 configuration, the battlecruisers were to carry ten 14"/50 caliber guns in four turrets, with two triple superfiring over two dual because there was not enough beam to accommodate the larger barbettes of the triple turrets slight further forward and aft.
