History

The Vickers machine gun was based on the successful Maxim gun

 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

Variants

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 (36.9 g) and was good for 1500 yd (1,371.6 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 Boat

Foreign service

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 mm Italian
  • 6.5 mm Arisaka
  • 6.5x54R Dutch
  • 7x57 Mauser
  • 7.5x55 Swiss

Specifications

The weight of the gun itself varied based on the gear attached, but was generally 25-30 lb, with a 40-50 lb tripod. The ammunition boxes for the 250-round ammunition belts weighed 22 lb each. In addition, it required about 7.5 imperial pint

s 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.

, 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. Some British tanks of the early Second World War were equipped with the 0.5 in Vickers.

The gun was 3 ft 8 in 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 yd.

Use

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 firing of the gun would make the barrel heat up, and conducted heat would then boil the water in the jacket, and steam would be carried away down a rubber pipe, to condense in a metal can. The condensed water could then be poured back into the jacket to top it up, but another function of the condenser tin was to hide the emissions of steam, that might give away the gun's position. This cooling system, though heavy, was very effective, and enabled the gun to keep firing far longer than air-cooled rival weapons.

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. 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 II 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.
