The Vickers machine gun or Vickers gun is a name primarily used to refer to the water-cooled .303 inch machine gun produced by Vickers Limited, originally for the British Army. The machine gun typically required a six to eight-man team to operate: one to fire, one to feed the ammunition, and the rest to help carry the weapon, its ammunition and spare parts.

The gun had a reputation for great solidity and reliability. Ian V. Hogg, in Weapons & War Machines, describes an action that took place in August, 1916, during which the 100th Company of the Machine Gun Corps fired their ten Vickers guns continuously for twelve hours. They fired a million rounds between them, using one hundred new barrels, without a single breakdown. "It was this absolute foolproof reliability which endeared the Vickers to every British soldier who ever fired one."[1]

History

The Vickers machine gun was based on the successful Maxim gun of the late 19th Century. After purchasing the Maxim company outright in 1896, Vickers took the design of the Maxim gun and improved it, reducing its weight, and adding a muzzle booster.

The British Army formally adopted the Vickers gun as its standard machine gun on 26 November 1912, using it alongside their Maxims. There were still great shortages when the First World War began, and the British Expeditionary Force was still equipped with Maxims when sent to France in 1914. Vickers was, in fact, threatened with prosecution for war profiteering, due to the exorbitant price it was demanding for the gun. The price was slashed as a result. As the war progressed, and numbers increased, it became the British Army's primary machine gun, and served on all fronts during the conflict. When the Lewis Gun was adopted as a light machine gun, and issued to infantry units, the Vickers guns, redefined as heavy machine guns were withdrawn from infantry units and grouped in the hands of the new Machine Gun Corps (when 0.5" calibre machine guns appeared, the tripod-mounted, rifle calibre machine guns like the Vickers became medium machine guns). After the War, the Machine Gun Corps (MGC) was disbanded and the Vickers returned to infantry units. Before the Second World War there were plans to replace it; one of the contenders was the 7.92 mm Besa machine gun (a Czech design), which eventually became the British Army's standard tank-mounted machine gun. However, the Vickers remained in service with the British Army until 30 March 1968. Its last operational use was in the Radfan during the Aden Emergency. Its successor in UK service is the L7 GPMG.

The Vickers became standard weapons on all British and French military aircraft after 1916, including the famous Sopwith Camel and the SPAD XIII. The gun was usually fitted with a form of synchronizer gear to allow it to fire through aircraft propellers, and slots were cut in the water jacket so that it was cooled by air flow instead of water, a common practice on WWI airplanes.

As the machine gun armament of fighters moved from the fuselage to the wings in the years before WW2, the Vickers with its cloth belts was generally replaced by the faster-firing Browning Model 1919. Several British bombers and attack aircraft of WW2 mounted the Vickers K machine gun, a completely different design.

Variants

The larger calibre (half-inch) version of the Vickers was used as an anti-aircraft gun on British ships as the 0.5"/62 Vickers Machine Gun Mark III. These were typically four guns on rotating (360°) elevating (+80° to -10°) mounting. The belts were rolled into a spiral and placed in hoppers beside each gun. The heavy plain bullet weighed 1.3 oz and was good for 1,500 yd range (1,300 m). They were fitted from the 1920s onwards but in practical terms proved of little use.

Foreign service

The Vickers was widely sold commercially and saw service with many nations and their own particular ammunition. For example:

The Vickers MG remains in service with the Indian, Pakistani, and Nepalese armed forces, albeit as a reserve weapon, intended for emergency use in the event of a major conflict.

Specifications

The weight of the gun itself varied based on the gear attached, but was generally between 25 and 30 pounds (11 and 13 kg), with a 40 to 50 pound (18 to 23 kg) tripod. The ammunition boxes for the 250 round ammunition belts weighed 22 pounds (10 kg) each. In addition, it required about 7.5 imperial pints (4.3 litres) of water in its evaporative cooling system to prevent overheating. The heat of the barrel boiled the water in the jacket surrounding it. The resulting steam was taken off by flexible tube to a condenser container - this had the dual benefits of avoiding giving away the gun's location, and also enabling re-use of the water, which was very important in arid environments.

Rimmed, centrefire Mk 7 .303 inch (7.7 mm) cartridge from WWII.

In British service, the Vickers gun fired the standard .303 inch (7.7 x 56 mm) cartridges used in the Lee Enfield rifle, which generally had to be hand-loaded into the cloth ammunition belts. There was also a 0.5 inch (12.7 mm) calibre version used as an anti-aircraft weapon and various other calibres produced for foreign buyers. Some British tanks of the early Second World War were equipped with the 0.5 inch (12.7 mm) Vickers.

The gun was 3 feet 8 inches (1.1 m) long and its cyclic rate of fire was between 450 and 600 rounds per minute. In practice, it was expected that 10,000 rounds would be fired per hour, and that the barrel would be changed every hour - a two-minute job for a trained team. Firing the Mark 8 cartridge, which had a streamlined bullet, it could be used against targets at a range of approximately 4,500 yards (4.1 kilometres).

    "The Vickers gun accompanied the BEF to France in 1914, and in the years that followed proved itself to be the most reliable weapon on the battlefield, some of its feats of endurance entering military mythology. Perhaps the most incredible was the action by the 100th Company of the Machine Gun Corps at High Wood on August 24, 1916. This company had ten Vickers guns, and it was ordered to give sustained covering fire for 12 hours onto a selected area 2,000 yards away in order to prevent German troops forming up there for a counter-attack while a British attack was in progress. Two whole companies of infantrymen were allocated as carriers of ammunition, rations and water for the machine-gunners. Two men worked a belt-filling machine non-stop for 12 hours keeping up a supply of 250-round belts. One hundred new barrels were used up, and every drop of water in the neighbourhood, including the men’s drinking water and contents of the latrine buckets, went up in steam to keep the guns cool. And in that 12-hour period the ten guns fired a million rounds between them. One team fired 120,000 from one gun to win a five-franc prize offered to the highest-scoring gun. And at the end of that 12 hours every gun was working perfectly and not one gun had broken down during the whole period. It was this absolute foolproof reliability which endeared the Vickers to every British soldier who ever fired one. It never broke down; it just kept on firing and came back for more. And that was why the Mark 1 Vickers gun was to remain the standard medium machine-gun from 1912 to 1968."
