An Anti-Aircraft gun experiences a catastrophic failure which causes the rounds to continue firing as the turret freely spins in a 360 degree arc.
Two anti-aircraft platforms are firing on targets in the distance when one of them experiences a serious malfunction. As the rounds continuously cook-off towards the original target, the crew attempts to maintain positive control of their weapon system while aiming towards the target.
They slowly begin to elevate the muzzle, and that’s when catastrophe strikes. While the barrels are elevating, the turret starts freely spinning in the direction of its sister. Seconds later the camera is cut, as the cameraman attempts to find cover.
The 2K22 Tunguska is a Russian tracked self-propelled anti-aircraft weapon armed with a surface-to-air gun and missile system. It is designed to provide day and night protection for infantry and tank regiments against low-flying aircraft, helicopters, and cruise missiles in all weather conditions. Its NATO reporting name is SA-19 “Grison.” (Source)
Guidance is performed by the target tracking radar, it constantly relays target range, elevation and bearing to the fire-control computer, and on the basis of this data the computer generates the laying commands for the guns or the trajectory corrections for the missiles.
A back-up tracking method can be used by the gunner, who uses the 8× magnification stabilized sight of the Tunguska to track the target in elevation and azimuth, the altitude or range of the target being set manually. The gunner is initially cued towards the target by the system’s search radar. Once the missile is steered to within 5m of the target, an active laser is triggered.
