The Ordnance QF 25-pounder, or more simply 25-pounder or 25-pdr, with a calibre of 3.45 inches (87.6 mm), was a piece of field artillery used by British and Commonwealth forces in the Second World War. It was often described as being durable, easy to operate and versatile. It was the major British field gun and howitzer during the War.
It was introduced into service just before the War started, and combined both high-angle and direct-fire abilities, a relatively high rate of fire, and a reasonably lethal shell, with a highly mobile piece. Initial production was slow but, by 1945, over 12,000 had been manufactured. It remained the British Army's primary artillery field piece well into the 1960s, with smaller numbers used in training units until the 1980s. Many Commonwealth countries used theirs in active or reserve service until about the 1970s, and ammunition for the weapon is currently (2020s) being produced by Pakistan Ordnance Factories.
