List of main battle tanks by generation
Main battle tanks are often classified as belonging to a particular generation, although the actual definition and membership in these generations is not clearly defined. Soviet and Russian military planners organize tanks into a generation of tanks up to 1945, and four generations of main battle tanks,〔“The Soviets saw tank generations in this manner: 1920-1945, first generation; 1946-1960, second generation; 1961-1980, third generation; and 1981-present, fourth generation. Since the last really new tank design, the T-80, came out in 1976, they feel that they have not produced a true Fourth Generation Tank Design. In comparison, they count the M1, Challenger, and Leopard 2 as Fourth Generation and the LeClerc as Fifth Generation.” —Sewell 1988, note 1.〕 while Canadian strategists organize main battle tanks into three generations.〔“The Canadian Directorate of Land Strategic Concept defines three generations of Main Battle Tanks. The first generation of post World War II Main Battle Tanks includes the U.S. M48/M60, the German Leopard 1 and the British Centurion and Chieftain. The second generation includes most of the 120 mm Main Battle Tanks such as the American M1A1, the German Leopard 2 and the British Challenger. As for the third generation Main Battle Tank, they include the latest ‘digital’ tank such as the French Leclerc and perhaps the American M1A2 and the German Leopard 2A5.” —Lamontagne 2003, pp 7–8.〕 The military of the People's Republic of China also recognizes three generations of its own tanks.
In 1983, Rolf Hilmes saw three tank generations and three "intermediate generations", which consisted mainly of upgraded vehicles.〔Hilmes, p. 7〕 The first generation of main battle tanks were based on or influenced by designs of World War II, most notably the T-34 and the Panther tank.〔Hilmes, p. 8〕 The second generation was equipped with NBC protection (only sometimes), IR night vision devices, a stabilized main gun and at least a mechanical fire control system.〔 The third generation is determined by the usage of thermal imagers, digital fire control systems and special (composite) armour.〔
However, Hilmes acknowledged that tanks cannot be definitively grouped by generations, as each tank producing country develops and introduces its tanks in tune with its own ideas and needs. He also states that breakdown of postwar tanks by generations is based on timeframe and technical factors, as a basis for further discussion.''〔
==First generation==
The first generation consists of the medium tanks designed and produced directly after World War II that were later redefined as main battle tanks.
