List of main battle tanks by generation

British Centurion main battle tank

T-55 main battle tank

Main battle tanks are often classified as belonging to a particular generation, although the actual definition and membership in these generations are not defined. Soviet military planners organize tanks with the first generation of tanks up to 1950, and four generations of tanks (with the first main battle tank being the third-generation T-64), while American strategists organize main battle tanks into three generations. The military of the People's Republic of China also recognizes three generations of its own tanks.

In 1973, Rolf Hilmes saw three tank generations and three "intermediate generations", which consisted mainly of upgraded vehicles. The first generation of main battle tanks was based on or influenced by designs of World War II, most notably the Soviet T-34. The second generation was equipped with NBC protection (only sometimes), night-vision devices, a stabilized main gun and at least a mechanical fire-control system. The third generation is in Western parlance determined by the usage of thermal imagers, digital fire-control systems and special (composite) armour (Soviet doctrine, however, de-emphasizes thermal vision and electronic fire control, preferring large-caliber gun and engines of high power).

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.

Explanatory notes

• Note to the Pancerni website source: Translation of most important parts of 1st, 2nd, 2.5 and 3rd generation MBTs characteristics: "The first generation MBTs are tanks made immediately after WWII. The second generation MBTs have better sights in comparison to the first generation MBTs. Also second generation MBTs were the first ones to use laser sights and APFSDS rounds. The third generation consists of tanks armed with high caliber and velocity guns like M1A1 Abrams. Third generation tanks also use composite armour as well as armour made out of highly resistant sintered ceramic materials. Third generation tanks also have full stabilization system for the main gun. There are tanks between second and third generations, like Soviet T-72 which has powerful gun which would classify it as a third generation MBT but at the same time the stabilization system is much too primitive for it to a third generation MBT. It also lacks engine power to be a third generation MBT and has ammunition with less quality."
