History, description[edit | edit source]
The gun was designed and built by Vickers specifically as a field gun, unlike its predecessors which originated as naval guns. Its length was reduced from the 45 calibres of its naval gun predecessors, to 35 calibres, to reduce weight and improve mobility. It utilized the modern carriage and recoil mechanism of the BL 8 inch Howitzer Mk 6.
"The breech mechanism is operated by means of a lever on the right side of the breech. On pulling the lever to the rear the breech screw is automatically unlocked and swung into the loading position. After loading, one thrust of the lever inserts the breech screw and turns it into the locked position. The breech mechanism is similar to that used on the 8 inch howitzers both in design and operation".
Operational history[edit | edit source]
British service[edit | edit source]
310 were built during World War I and the gun served in all theatres, with 108 being in service on the Western front at the end of World War I, but it did not completely replace the Mk VII gun until the end of the war.
3 batteries served with the BEF in France early in World War II, and others were deployed in the home defence of Britain. The gun was superseded by the 155-mm Gun M1, and the carriages used for 7.2-inch (183 mm) howitzers.
US Service[edit | edit source]
"Handbook of artillery" of May 1920 stated that :
"The original British ammunition so closely resembled the American that it was decided to use the [US] regular Mark II high-explosive shell... the propellant charge will consist of a base section and increment section having a total weight of approximately 25 pounds".
Brazil service[edit | edit source]
Brazil purchased these guns from USA in 1940 for coastal defense.
South African service[edit | edit source]

- I.e. Mark 19 : Britain at the time designated Marks (models) of ordnance using Roman numerals. This was a field gun and field ordnance normally used a different Mark series to naval ordnance, but unusually the next available Mark number in the 6-inch naval gun series was used, rather than Mark I as the first 6-inch BL field gun.
