Unusual ZSU "Otomatik" made in the early 90's in Italy. It is armed with 76-mm automatic cannon. The choice is so large caliber grounded object to hit the helicopters before the launch of their anti-tank missiles. The chassis is created on the basis of 155-mm self-propelled howitzer "Palmira". Fighting weight "Otomatika" 46 tons Allowance of ammunition 100 shells. Of course, the increase in the caliber anti-aircraft guns and has bad consequences: reduced rate of fire guns, decreases allowance of ammunition due to the increase of weight projectile, often errors occur when shooting at large distances.
These events prompted the developers the ability to search for adjusting the trajectory of the projectile in the target area. The solution was found in the equipment of his impulse engine adjustments, representing soboyshest small charge to be placed in the body shell. Accordingly, motor start-up you can change the line of motion of the projectile in the range of 10 ° in any direction relative to the velocity vector on the on-ground control system. Listener is located at the bottom of the shell, and its antenna in the form of a cross-shaped array of 4 parts — on the feathers of the stabilizer.
Specialists believe that such shell, equipped with a non-contact and contact fuses, which will allow helicopters to fight at distances of 8-10 km. Rate it 5 — 10 times higher than the ordinary, but, according to the views of foreign experts, with a 50 percent probability of hitting the target is completely successful candidate SAM.
Are also ongoing work to create a shell that brings the laser beam. It has a sensor for determining the angular difference from the band of sight, with the help of which the management of the gas switches of the control mechanism and changes Line Movement flight. It is believed that the projectile guidance by a laser beam, coupled with the proximity fuse will provide opportunity defeats the purpose of 0.5 — 0.7.
