Why Russian tanks are prone to catastrophic explosions
Russian tanks are considered armored coffins for a reason. A relatively small internal damage can lead to a huge explosion. Here's how it's possible.
The video below shows a lightly smoking tank from the T-80 or T-72/90 family, which explodes with tremendous force shortly after. After the fact, little remains of the machine and the turret, thrown several meters into the air, fall a few meters away.
Why do Russian tanks explode like this?
Russian tanks, according to the design requirements resulting from the Soviet nuclear experiment described by Wirtualna Polska journalist Łukasz Michalik.
For this reason, Russian machines from the T-64, T-80, T-72, and T-90 families are equipped with a carousel autoloader. However, some differences exist between the Malyshev Factory designs in Kharkiv and the Uralvagonzavod in Nizhny Tagil.
The former's autoloader is more complicated and provides slightly higher firing rates combined with a larger ammunition reserve (28 rounds). It is also worth noting that the rounds are placed horizontally while the propellant charges are placed vertically.
On the other hand, the autoloader of the T-72 and T-90 machines is slightly simpler, resulting in a lower firing rate and a smaller ammunition reserve (22 rounds). In this case, both the rounds and the propellant charges are laid out horizontally.
However, both ammunition magazines are not isolated from the crew, and in the event of an explosion, it does not matter much whether the crew is sitting on top of the ammunition or surrounded by it. Furthermore, the rounds in the autoloader represent only about half of the maximum ammunition reserve because the rest of the rounds and propellant charges are scattered in holders throughout the tank.
This lack of ammunition isolation and the inability to vent the explosion force outward means that any fire within the tank or penetration of a cumulative jet into its interior guarantees an immediate or delayed huge explosion, resulting in the turret being torn off.
This is a different approach than modern Western machines like the Leopard 2, M1A2 Abrams, or Leclerc, where the ammunition is placed at the back of the turret and isolated from the crew by a steel plate. Additionally, the ammunition magazines in these tanks have weak points that direct the explosion force outward in the event of an ammunition explosion.
This is very important because even in the event of armour penetration of a Western tank, there is a small risk of the entire crew dying if they are not in the path of the cumulative jet. For example, one of the Ukrainian tankers serving on an M1A1 Abrams mentioned that in the case of one hit, the driver lost a leg but survived, as did the rest of the crew.
