History
Hiram Maxim originally designed the Pom-Pom in the late 1880s as an enlarged version of the
Maxim machine gunThe Maxim gun was the first self-powered machine gun, invented by the American-born British inventor Sir Hiram Maxim in 1884. It has been called "the weapon most associated with [British] imperial conquest".-Functionality:...
. Its longer range necessitated exploding projectiles to judge range, which in turn dictated a shell weight of at least 400 gram (0.88184904873951 lb), as that was the lightest exploding shell allowed under the St. Petersburg Declaration of 1868 and reaffirmed in the
Hague Convention of 1899The Hague Conventions were two international treaties negotiated at international peace conferences at The Hague in the Netherlands: The First Hague Conference in 1899 and the Second Hague Conference in 1907...

airships sufficiently to bring them down. The Ministry of Munitions noted in 1922: "The pom-poms were of very little value. There was no shrapnel available for them, and the shell provided for them would not burst on aeroplane fabric but fell back to earth as solid projectiles... were of no use except at a much lower elevation than a Zeppelin attacking London was likely to keep".
Nevertheless, Lieutenant O.F.J. Hogg of No. 2 AA Section in III Corps was the first anti-aircraft gunner to shoot down an aircraft, with 75 rounds on 23 September 1914 in France.
The British Army did not employ it as an infantry weapon in World War I, as its shell was considered too small for use against any objects or fortifications and British doctrine relied on shrapnel fired by QF 13 pounder and 18-pounder field guns as its primary medium range anti-personnel weapon.
The gun was tried with only limited success mounted on aircraft as the lighter 1-pounder Mk III, and was quickly replaced by the larger QF 1½ pounder and

naval guns as a light anti-aircraft gun.
British Ammunition
The British are reported to have initially used some Common pointed shells (semi-armour piercing, with fuze in the shell base) in the Boer War, in addition to the standard Common shell. However, the common pointed shell proved unsatisfactory, with the base fuze frequently working loose and falling out during flight. In 1914, the cast-iron common shell and tracer were the only available rounds.

German service
A version was produced in Germany for both Navy and Army.
In World War I, it was used in Europe as an anti-aircraft gun as the
Maxim Flak M14. Four guns were used mounted on field carriages in the German campaign in South West Africa in 1915, against South African forces.
