The '''4.7 inch/45 Mk.XII''' is a 45-calibre, 4.7-inch (120 mm) naval gun which armed the majority of Royal Navy and Commonwealth destroyers during World War II, later being exported to many other countries.
 
−
 
 
−
This gun succeeded the similar World War I-era BL 4.7 inch gun, changing the cartridges from BL silk bags to separate QF in brass cases and a new horizontal sliding-block breech mechanism. The Mk XII gun was deployed in twin mountings CP Mk XIX on the [[Tribal (Family)|Tribal-class]] and [[G and H class (Family)|G-class]] destroyers of 1936 as well as the [[HMS Jervis|J-class]], [[HMS Kelvin|K-class]], and [[HMAS Nepal|N-class]] of 1938. 
 
−
 
 
−
The 4.7 inch calibre was finally superseded by the 4.5 inch calibre on the Z-class destroyers in 1943. The new 4.5 inch gun had 55-degree elevation mounts and actually fired a shell slightly heavier than that of 4.7-inch XII guns.

History

4.7 inch/45 Mk.XII on HMAS Nizam

Examine the history of the creation and combat usage of the weapon in more detail than in the introduction.
