Overview

Work began in 1950s and first trials were in mid-1956. Later that year a T-54A, driven by Hungarians drove into the British embassy in Budapest. After a brief examination of the tank's armour and 100mm gun, British officials decided that the Ordnance QF 20 Pounder was apparently incapable of defeating it - hence a need for this 105mm gun. The L7 was designed to fit the same space of that of a 20 Pdr, allowing existing tanks equipped with 20 Pdrs to upgrade to the L7.

The L7 succeeded the Ordnance QF 20 Pounder (84mm) and superseded by the 120mm Royal Ordnance L11
