The Vickers machine gun or Vickers gun is a name primarily used to refer to the water-cooled .303 British (7.7 mm) 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, the rest to help carry the weapon, its ammunition and spare parts. It served from before the First World War until the 1960s, with air-cooled versions of it serving on World War I aircraft of many of the Allied air forces’ fighters.
The weapon 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 British Army's 100th Company of the Machine Gun Corps fired their ten Vickers guns continuously for twelve hours. Using 100 new barrels, they fired a million rounds without a single failure. “It was this absolute foolproof reliability which endeared the Vickers to every British soldier who ever fired one.”
History[edit | edit source]
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 by lightening and simplifying the action and substituting components made with high strength alloys. A muzzle booster was also added.
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 each gun. As a result, the price was slashed. 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was adopted as a light machine gun and issued to infantry units, the Vickers guns were redefined as heavy machine guns, withdrawn from infantry units, and grouped in the hands of the new Machine Gun Corps (when heavier 0.5 in/12.7 mm calibre machine guns appeared, the tripod-mounted, rifle-calibre machine guns like the Vickers became medium machine guns). After the First World 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 the Vickers gun; one of the contenders was the 7.92 mm (.312 in) 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.
Use in aircraft[edit | edit source]
In 1913, a Vickers machine gun was mounted on the experimental Vickers E.F.B.1 biplane, which was probably the world's first purpose-built combat aeroplane. However, by the time the production version, the Vickers F.B.5, had entered service the following year, the armament had been changed to a Lewis gun.
During World War I, the Vickers gun became a standard weapon on British and French military aircraft, especially after 1916. Although heavier than the Lewis, its closed bolt firing cycle made it much easier to synchronize to allow it to fire through aircraft propellers. The belt feed was enclosed right up to the gun's feed-way to inhibit effects from wind. Steel disintegrating-link ammunition belts were perfected in the UK by Prideaux in mid-war and became standard for aircraft guns thereafter. The famous Sopwith Camel and the SPAD XIII types used twin synchronized Vickers, as did most British and French fighters between 1918 and the mid-1930s. In the air, the weighty water cooling system was redundant, but because the weapon relied on barrel recoil, the (empty) water-holding barrel jacket or casing needed to be retained. Several sets of louvred slots were cut into the barrel jacket to aid air cooling.
As the machine gun armament of fighter aircraft moved from the fuselage to the wings in the years before the Second World War, the Vickers, was generally replaced by the faster-firing Browning Model 1919 using metal-linked cartridges. The Gloster Gladiator was the last RAF fighter to be armed with them, although they were later replaced by Brownings. The Fairey Swordfish continued to be fitted with the weapon until production ended in August 1944.
Several British bombers and attack aircraft of the Second World War mounted the Vickers K machine gun or VGO, a completely different design.
Variants[edit | edit source]
The larger calibre (half-inch) version of the Vickers was used on armoured fighting vehicles and naval vessels.
The Gun, Machine, Vickers, .5-inch, Mk. II was used in tanks, the earlier Mark I having been the development model. This entered service in 1933 and was obsolete in 1944. Firing either single shot or automatic it had a pistol type trigger grip rather than the spades of the 0.303 in (7.7 mm) cartridge.
The Gun, Machine, Vickers, .5-inch, Mk. III was used as an anti-aircraft gun on British ships. This variation was typically four guns mounted on a 360° rotating and (+80° to −10°) elevating housing. The belts were rolled into a spiral and placed in hoppers beside each gun. The heavy plain bullet weighed 1.3 oz (37 g) and was good for 1,500 yd (1,400 m) range. Maximum rate of fire for the Mark III was about 700 rpm from a 200-round belt carried in a drum. They were fitted from the 1920s onwards, but in practical terms, proved of little use. During the Second World War, the naval 0.5 in (12.7 mm) version was also mounted on power-operated turrets in smaller watercraft, such as Motor Gun Boats and Motor Torpedo Boats.
Foreign service[edit | edit source]
The Vickers was widely sold commercially and saw service with many nations and their own particular ammunition. It was also modified for each country and served as a base for many other weapons. For example:
- 6.5×52mm Mannlicher-Carcano
- 6.5×50mmSR Arisaka
- 6.5×53.5mm R Dutch
- 7×57mm Mauser
- 7.5×55mm Swiss
- 7.62×51mm NATO
- .30-06 Springfield
- 7.65×53mm Argentine
- 8mm Lebel
The Vickers MG remains in service with the Indian, Pakistani, and Nepalese armed forces, as a reserve weapon, intended for emergency use in the event of a major conflict.
Specifications[edit | edit source]
The weight of the gun itself varied based on the gear attached, but was generally 25 to 30 pounds (11 to 14 kg) with a 40-to-50-pound (18 to 23 kg) tripod. The ammunition boxes for the 250-round ammunition belts weighed 22 pounds (10.0 kg) each. In addition, it required about 7.5 imperial pints (4.3 l) 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.
In British service, the Vickers gun fired the standard .303 inch 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 in calibre version used as an anti-aircraft weapon and various other calibres produced for foreign buyers.
The gun was 3 feet 8 inches (112 cm) 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 boat tailed bullet, it could be used against targets at a range of approximately 4,500 yards (4,100 m).
Use[edit | edit source]
The gun and its tripod were carried separately and both were heavy. The original design did not anticipate its being carried up jungle-covered mountains on men's backs, but such was the weapon's popularity that men were generally content to man-pack it to all manner of difficult locations. The tripod would be set up to make a firm base, often dug into the ground a little and perhaps with the feet weighted down with sandbags. The water jacket would be filled with water around the barrel. The evaporative cooling system, though heavy, was very effective and enabled the gun to keep firing far longer than air-cooled rival weapons. If water was unavailable, soldiers were known to resort to using their urine. It was sometimes claimed that crews would fire off a few rounds simply to heat their gun's cooling water to make tea, despite the resulting brew tasting of machine-oil.
The loader sat to the gunner's right, and fed in belts of cloth, into which the rounds had been placed. The weapon would draw in the belt, pull each round out of the belt and into the breech, fire it, and then drop the brass cartridge out of the bottom, to gather in a pile of spent brass underneath the weapon, while the cloth belt would continue through to the left side and wind up on the ground.
The Vickers was used for indirect fire against enemy positions at ranges up to 4,500 yards (4,100 m). This plunging fire was used to great effect against road junctions, trench systems, forming up points, and other locations that might be observed by a forward observer, or zeroed in at one time for future attacks, or guessed at by men using maps and experience. Sometimes a location might be zeroed in during the day, and then attacked at night, much to the surprise and confusion of the enemy. New Zealand units were especially fond of this use. A white disc would be set up on a pole near the MMG, and the gunner would aim at a mark on it, knowing that this corresponded to aiming at the distant target. There was a special back-sight with a tall extension on it for this purpose. The only similar weapon of the time to use indirect fire was the German MG 08, which had a separate attachment sight with range calculator.
A British, World War 2, Vickers MMG platoon typically had one officer in command of four guns, in two sections of two, each with a crew and a small team of riflemen whose job was to protect the gun, and keep it supplied with ammunition.

“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 24 August 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.”
