QF 1 pounder pom-pom
Encyclopedia
The QF 1 pounder, universally known as the pom-pom, was an early 37 mm British
autocannon
. It was used by several countries initially as an infantry gun and later as a light anti-aircraft gun. The name comes from the sound it makes when firing.
. 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 1899
.
Early versions were sold under the Maxim-Nordenfelt
label, whereas versions in British service (i.e. from 1900) were labelled Vickers, Sons and Maxim (VSM) as Vickers
had bought out Maxim-Nordenfelt in 1897. They are all effectively the same gun.
The British government initially rejected the gun but other countries bought it, including the South African Republic
(Transvaal) government. In the Second Boer War
, the British found themselves being fired on with success by the Boers with their 37 mm Maxim-Nordenfelt
versions with ammunition made in Germany.
In response, Vickers-Maxim of Britain shipped either 57 or 50 guns out to the British Army
in South Africa, with the first three arriving in time for the Battle of Paardeberg
of February 1900. These early Mk I versions were mounted on typical field gun
type carriages.
mountings and deployed along London docks and on rooftops on key buildings in London, others on mobile motor lorries at key towns in the East and Southeast of England. 25 were employed in August 1914, and 50 in February 1916. The Mk II gun at the top of this page on Naval pedestal mounting was the first to open fire in defence of London during the war. However, the small shell was insufficient to damage the German Zeppelin
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 QF 2 pounder
naval guns as a light anti-aircraft gun.
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.
The U.S. Navy
adopted the Maxim-Nordenfelt 37 mm 1 pounder as the 1-pounder Mark 6 before the 1898 Spanish–American War.

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. |
