The Ordnance ML 3-inch mortar was the United Kingdom's standard mortar used by the British Army from the late 1920s to the late 1960s, superseding the Stokes Mortar.

History

Based on their experience in World War I, the British infantry sought some sort of artillery for close support. The initial plan was for special batteries of artillery, but the cost was prohibitive and the mortar was accepted instead.

The ML mortar is a conventional Stokes-type mortar which is muzzle-loaded and drop-fired. Experience in World War II showed that it did not have sufficient range compared to the German 81 mm s.Gw.34 mortar and so a new barrel was designed. This became the Mark 2 mortar, which remained in service until replaced by the L16A1 81mm mortar.
