The Royal Ordnance L7 is the basic model of Britain's most successful tank gun. The L7 was a 105 mm rifled design intended for use in armored fighting vehicles. It was so successful that it armed not only British post-war designs, but was used almost universally in "the West" as the main armament of almost every main battle tank. A M1 Abrams firing. ...

The L7 was a popular weapon and it was maintained in use even after it was superseded by the L11 series 120 mm rifled tank gun for some Centurion tanks operating as Artillery Forward Observation and AVRE vehicles. The L7, and adaptations of it, can be found today as standard or retrofitted equipment on a wide variety of tanks developed during the Cold War. It is also being used as the main armament of the US Army's Stryker-based Mobile Gun System. It has been suggested that United States Army values be merged into this article or section. ...

History
During the Hungarian Revolution of 1956, a Soviet T-54A medium tank was driven onto the grounds of the British embassy in Budapest by the Hungarians. After an examination of this tank's armour and 100 mm gun, British officials decided to adopt a 105 mm gun.[1] The L7 was specifically designed as a replacement to fit into the turret mountings of the 20 pounder, which was seen as incapable of defeating the current and future Warsaw Pact tank designs (T-54 and IS-3). This would enable the Centurions to be upgunned with a minimum of modifications and hence the fleet could be upgraded in a shorter time and at a lower cost.

The breech uses a horizontally-sliding breechblock for loading the fixed cartridge cases. The gun recoils approximately 29 cm (in most applications), automatically ejects the empty cartridge case upon reaching full recoil. The barrel of the L7 is fitted with a bore evacuator approximately halfway down its length. It is eccentrically mounted, which is a key recognition feature. A breechblock is the part of the firearm action that closes the breech at the moment of firing. ...

The first tank to be equipped with the L7 was the Centurion Mark 5 in 1959.[citation needed] The gun was subsequently adopted by several other nations for their own MBTs, most notably the German Leopard 1 (for which the L7A3 variant was developed), the Japanese Type 74 (produced under license by Japan Steel Works), the Swedish Stridsvagn 103 (as the L74, with a longer barrel and automatic loader), the US M60 series of tanks (with the M68), and the Israeli Merkava. In addition, several countries have used the gun to improve the firepower of existing main battle tanks. Derivatives have even been mounted in Warsaw Pact-built T-54 and T-55 tanks in Israel and Iraq, and Type 79 tanks in China. Year 1959 (MCMLIX) was a common year starting on Thursday of the Gregorian calendar. ...
