The QF 4 inch Mk V gunMk V = Mark 5. Britain used Roman numerals to denote Marks (models) of ordnance until after World War II. Mark V indicates this was the fifth model of QF 4-inch gun. was a Royal Navy gun of World War I which was adapted on HA (i.e. high-angle) mountings to the heavy anti-aircraft role both at sea and on land, and was also used as a coast defence gun.
This QF gun was introduced to provide a higher rate of fire than the BL 4 inch Mk VII. It first appeared in 1914 as secondary armament on s, was soon adapted to a high-angle anti-aircraft role. It was typically used on cruisers and heavier ships, although s of 1917 also mounted the gun.
Mk V was superseded by the QF 4 inch Mk XVI as the HA (i.e. anti-aircraft) gun on new warships in the 1930s, but it continued to serve on many ships such as destroyers, light and heavy cruisers in

Army anti-aircraft gun
Early in World War I several guns were supplied by the Navy for evaluation as anti-aircraft guns for the home defence of key installations in Britain. They were mounted on static platforms and proved fairly successful after a fixed round was developed to replace the original separate round, and more followed. The AA mounting allowed elevation to 80° but loading was not possible above 62°, which slowed the maximum rate of fire. At the Armistice a total of 24 guns were employed in AA defences in Britain and 2 in France. After World War I the guns were returned to the Navy.Coast Defence gun
From 1915 to 1928 several guns were mounted in forts to guard the estuary of the River Humber.Anti-aircraft performance
Ammunition
Ammunition for the original low-angle guns introduced in World War I was Separate QF i.e. the shell and cartridge were separate items, but in World War II most guns used Fixed QF ammunition i.e. a single unit. The fixed Mk V ammunition was 44.3 inches (1.13 m) long and weighed 56 pounds (25 kg), while the projectile was 31 pounds (14 kg).Campbell, ''Naval Weapons of WWII'', p.58.See also
