This is a list of tank main guns which are designed or used as the primary weapon of combat by tanks, such as light tanks, medium tanks, heavy tanks, or main battle tanks. Many tanks have other, secondary weapons installed in them, such as machine guns, autocannons and small calibre mortars, which are not included in this list.
Also excluded from this list are weapons installed in self-propelled artillery vehicles such as assault guns or tank destroyers that usually lack turrets. This is due to the unique nature of turreted tank tactics, their design, and operation.
The Merkava is a series of main battle tanks (MBT) used by the Israel Defense Forces (IDF) and the backbone of the IDF's Armored Corps. Current iterations of this tank are considered broadly equivalent to the capabilities of the M1 Abrams, Leopard 2 and the Challenger 2. The current iteration of this vehicle also shares the same MTU EuroPowerPack powerplant as a number of other MBT platforms.
The Kliment Voroshilov tanks are a series of Soviet heavy tanks named after the Soviet defence commissar and politician Kliment Voroshilov who operated with the Red Army during World War II. The KV tanks were known for their heavy armour protection during the early stages of the war, especially during the first year of the German invasion of the Soviet Union. In certain situations, even a single KV-1 or KV-2 supported by infantry could halt German formations. The German Wehrmacht at that time rarely deployed its tanks against KVs, as their own armament was too poor to deal with the "Russischer Koloss" – "Russian Colossus".
The T-62 is a Soviet main battle tank that was first introduced in 1961. As a further development of the T-55 series, the T-62 retained many similar design elements of its predecessor including low profile and thick turret armour.
The T-35 was a Soviet multi-turreted heavy tank of the interwar period and early Second World War that saw limited service with the Red Army. Often called a land battleship, it was the only five-turreted heavy tank in the world to reach production, but proved to be slow and mechanically unreliable. Most of the T-35 tanks still operational at the time of Operation Barbarossa were lost due to mechanical failure rather than enemy action. It was designed to complement the contemporary T-28 medium tank; however, very few were built.
The BT-7 was the last of the BT series of Soviet cavalry tanks that were produced in large numbers between 1935 and 1940. It was lightly armoured, but reasonably well-armed for the time, and had much better mobility than other contemporary tank designs. The BT tanks were known by the nickname Betka from the acronym, or its diminutive, Betushka.
The M3 Lee, officially Medium Tank, M3, was an American medium tank used during World War II. The turret was produced in two forms, one for US needs and one modified to British requirements to place the radio next to the commander. In British Commonwealth service, the tank was called by two names: tanks employing US-pattern turrets were called "Lee", named after Confederate general Robert E. Lee, while those with British-pattern turrets were known as "Grant", named after Union general Ulysses S. Grant.
The M48 Patton is an American first-generation main battle tank (MBT) introduced in February 1952, being designated as the 90mm Gun Tank: M48. It was designed as a replacement for the M26 Pershing, M4 Sherman, M46 and M47 Patton tanks, and was the main battle tank of the U.S. Army and U.S. Marine Corps in the Vietnam War. Nearly 12,000 M48s were built, mainly by Chrysler and American Locomotive Company, from 1952 to 1961. The M48 Patton was the first U.S. medium gun tank with a four-man crew, featuring a centerline driver's compartment and no bow machine gunner. As with nearly all new armored vehicles it had a wide variety of suspension systems, cupola styles, power packs, fenders and other details among individual tanks.
The M60 is an American second-generation main battle tank (MBT). It was officially standardized as the Tank, Combat, Full Tracked: 105-mm Gun, M60 in March 1959. Although developed from the M48 Patton, the M60 tank series was never officially christened as a Patton tank. It has been called a "product-improved descendant" of the Patton tank's design. The design similarities are evident comparing the original version of the M60 and the M48A2. The United States fully committed to the MBT doctrine in 1963, when the Marine Corps retired the last (M103) heavy tank battalion. The M60 tank series became America's primary main battle tank during the Cold War, reaching a production total of 15,000 M60s. Hull production ended in 1983, but 5,400 older models were converted to the M60A3 variant ending in 1990.
A gun turret is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation.
The Dardo is an infantry fighting vehicle designed for the Italian Army as a replacement for the M113 APC. It is designed and built by the Iveco Fiat Oto Melara Syndicated Company based in Rome. Iveco is responsible for the hull and propulsion systems, while Oto Melara is responsible for the weapons and fire control systems.
The Heavy Tank M6 was an American heavy tank designed during World War II. The tank was produced in small numbers and never saw combat.
The Landkreuzer P. 1000 "Ratte" was a design for a 1000-ton tank to be used by Germany during World War II which may have been proposed by Krupp director Edward Grote in June 1942, who had already named it "Landkreuzer". Submitted designs and drawings of the vehicle went under the names OKH Auftrag Nr. 30404 and E-30404/1, which were presented in December 1942. The tank was planned to be 1000 tonnes, far heavier than the Panzer VIII "Maus", the heaviest tank ever built. The project gained the approval of Adolf Hitler, who had expressed interest in the development of the tank but was cancelled by Minister of Armaments Albert Speer in early 1943.
The Type 95 heavy tank was the final result of Japanese multi-turreted tank design and was in commission during the time period between World War I and World War II. The main armament being a 70 mm cannon in a central turret, with its secondary front turret mounting a 37 mm gun and a 6.5 mm machine gun in the rear turret. Four prototypes were produced in 1934.
The German 28 cm SK C/34 naval gun was a 283 mm 54.5-caliber built-up gun designed in 1934 used on the Scharnhorst-class battleship and for the planned Landkreuzer P. 1000 Ratte super-heavy tank.
The AMX 50 or AMX-50 is a French heavy tank designed in the immediate post Second World War period. It was proposed as, in succession, the French medium, heavy, and main battle tank, incorporating many advanced features. It was cancelled in the late 1950s however, due to unfavourable economic and political circumstances after serious delays in development.
Object 187, was a Soviet experimental main battle tank developed between the late 1980s and middle 1990s. It remains a relatively unpublicized development because of high levels of secrecy surrounding the project.
An oscillating turret is a form of turret for armoured fighting vehicles, both tanks and armoured cars. The turret is unusual in being made of two hinged parts. Elevation of the gun relies on the upper part of the turret moving relative to the lower part.
The T-42 was a Soviet super-heavy tank project of the interwar period. It was developed in 1932 by the OKB-5 design bureau at Bolshevik Plant no. 232 under the direction of a German engineer-designer Edward Grote. Development did not advance past the stage of construction drawings and scale models. The design was passed over in favour of the T-35 project which was already at the prototype stage.
