Russia developing 152 mm tank gun and small battlefield nuclear weapons

Russia in considering upgrading future T-14 main battle tnks to use the 2A83 152 mm gun instead of its current 2A82 125 mm gun. The 2A83 gun has a high-speed APFSDS shell with a 1,980 m/s muzzle velocity, only dropping to 1,900 m/s at 2 km.

However, Russian engineers have so far kept the 125 mm-size gun, assessing that improvements in ammunition could be enough to increase effectiveness, while concluding that a larger bore weapon would offer few practical advantage.

Russia is both miniaturizing the nuclear warheads and using sub-kiloton low-yield warheads. Battlefield nuclear weapons could be pared with the larger tank gun.

The 152 mm tank gun could penetrate 1 meter of armor.

For 11 years, China has been testing a 140mm gun on one its Type 98 tanks. The 140mm gun could fire an armor piercing round with twice the penetrating power of one fired from a 120mm gun (about 22 mega joules of energy, versus 11), the amount of ammunition carried was reduced by about a third (to 20-30 rounds, depending on the tank). The 140mm shell was about fifty percent larger than the 120mm one, and could probably knock out an M-1 tank with a frontal shot.

When the Armata (T-14) tank gets the 152mm gun, it will be the most powerful cannon to be mounted on a main battle tank of any country ever.

  1. The US needs to pick up some of these ideas from Russia and China. The M1A1 Abrams tanks have 120mm guns which are effective, but won't be able to go against the new 152mm guns on foreign tanks. I'm assuming that Russian and Chinese tanks will also get an armor upgrade that might be able to stop America's 120mm guns.
