The AG-35/A-35 is a 35mm towed anti-aircraft guns designed by the PIT-RADWAR S.A company. They are intended to fight air targets as aircrafts (wing and rotary), cruise missiles and UAVs flying at low and very low altitudes, as well as light-armored ground and sea targets.KDA 35 mm automatic cannon would be the basic building block of the system developed by the PIT-RADWAR S.A company. The licence for manufacturing the system has been acquired by CNPEP RADWAR, now known as PIT-RADWAR S.A, in Switzerland, back in the year 1995.
KDA automatic cannon may shoot at the rate of fire of up to 550 rounds per minute, hitting targets at distance of up to 5.5 kilometers, flying at altitudes of 3.5 kilometres. The system remains effective against threats moving at a speed of up to 600 meters per second. The common components of the AG-35 and A-35 guns, besides of the 35mm automatic cannon which has a replaceable barrel, are a hydraulic gun control subsystem, a hydraulically deployed chassis, subsystem of drives, an automatic orientation and positioning subsystem, a communication and data exchange subsystem and an automated subsystem for programmable ammunition including the muzzle velocity measurement.
The subsystem of control of the automatic gun has dual-sided ammunition feeding from two magazines placed on both opposite sides of the automate cannon. Two types of ammunition for example the FAPDS-T and ABM, can be switched over. The subsystem of drives is built with use of electronically steered brushless servomotors to get both high dynamics and precision of movement. The navigation subsystem (intertial and GPS) enables immediate localization of the gun at the fire position and accurate and continuous measurement of the azimuth, pitch and roll angle.
Communication and data transmission system provide co-operation with the superordinate command system, co-operation with the WG-35 Fire Control Vehicle, wire communication (voice and data) as well as remote control from a portable terminal. The functions are accomplished by digital phone and wideband radio. The ZGS-158 integrated tracking head consists of a 3rd generation termovision camera, (3–5 mm), tv daylight camera , eye-safe laser rangefinder and IKZ-02 short range IFF interrogator. the AG-35 gun can operate in multiple modes resulting from combinations of various possibilities od localizing the target: with use of the own tracking head , the WG-35 tracking head, the surveillance post and the operator of remote portable terminal.
