BV64 Ballistic Calculator

Description 

The ballistic calculator is an integral part of the arms control system of modern tanks and allows to confidently hit targets from the first shot. BV64 provides ballistic calculations for 5 types of projectiles and operates within the arms control system.

The device is installed in T-64 tanks.

It is high shock and vibration resistant and is adapted to work in tough operating conditions.

Purpose of Use

Upgrading the arms control system improves the target hit precision by taking into account the target range, filler temperature, ambient air temperature, atmospheric pressure, barrel wear, crosswind speed, tilt in the lateral plane (roll), target velocity relative to the gun in the horizontal plane and projectile type.
