Historic and technical information
Denomination :     QF 3.7-in. mountain howitzer Origin :       ( Royal Arsenal)          

Historic context :

Unde the pression of the Indian army that was calling for a mountain howitzer to replace the obsolete BL 10-pdr (1901) and 2.75-in (1911) mountain guns, the British weapon industry had to wait for the war start and the arrival of a budget to design the brand new ‘QF 3.7-in pack howitzer’ that could be dismantled into 8 separate packs for its transportation. It was still a 'screw gun', with its barrel that could be separated in two sections linked with a thread.

This very efficient modern weapon was equipped with a variable hydro-pneumatic recoil recuperation system, a wide shield, and a new split-trail carriage (the very first split trail gun of the British arsenal). These characteristics, associated with an innovative suspension device of the carriage wheels gave it an very good capacity to be installed on very irregular grounds with a very wide fire angle of 40 degrees.

The 3.7-in mountain howitzers only joined the WW1 fights in 1917, on the Mesopotamia front annd the East Africa one. There was only 22 such guns in service in 1918. This weapon hour was yet to come. This happened in the interwars years, when it was used as a mountain gun by both the Royal Artillery and the Indian Artillery units. During WW2, it was intensively engaged by the British and the Commonwealth armies on all the fronts of Europe, Africa and Asia. Some nations kept them in service until 1965 !
