A-35/AG-35 Towed Anti-Aircraft 35mm Gun

The AG-35 and A-35 Towed Anti-Aircraft 35mm Guns are fire means designed to operate in an AA battery. 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. The guns have common design based on the 35mm automatic cannon (HSW), and differ in solution of aiming subsystem and fire control.

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. The 35 mm calibre AG-35 anti- aircraft gun and its A-35 variant are firepower which have been designed to operate within the anti- aircraft battery. They serve in particular for engagement of the aircraft, helicopters, wing rockets and unmanned combat air vehicles (UCAV) flying at very low, low and medium altitudes. These guns can engage the ground and seaborne lightly-armored targets.

The A-35 gun is to be connected to the tracking head vehicle and to work out the controls provided by vehicles fire control system. The integrated aiming sight can be used to fight the ground and sea surface targets. The AG-35 includes an additional integrated optoelectronic tracking head, a ballistic computer and a videotracker to set a fully operational aiming channel, capable of autonomous intercepting the threat and combat engagement.

The common components of the AG-35 and A-35 guns, besides of the 35mm HSW-produced 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 design of the both of accomplished variants has been based on the 35 mm automatic cannon produced by HSW S.A. but they have different targeting and fire control systems. The A-35 gun is mainly dedicated to be connected to the WG-35 fire control vehicle from which it is remotely controlled by the operator. The integrated programmable aiming sight of the gun can be utilized for engagement of both the land and seaborne targets.

By contrast, the AG-35 gun is equipped with the integrated optoelectronic tracking head, ballistic computer and videotracker. With these elements, it is possible to create fully functional aiming channel capable to independently acquire and combat the threat.

Beside the 35mm automatic cannon produced by HSW S.A. and equipped with a spare barrel as a standard, the other common components of the AG-35 and A-35 guns are: gun hydraulic control system, hydraulically folded/deployed chassis, drive sub-system, sub-system of automatic orientation and positioning based on the inertial navigation, the communication and data transmission sub-system, sub-system of ammunition feeding and integrated system for programmable ammunition with measurement of muzzle velocity.

Apart from typical functions, the control sub-system of the automatic gun has the capability to switch the sources of feeding the ammunition to one of the two magazines located on the opposite sides of the gun rotating platform. The best solution for a full spectrum of airborne and ground threats is the combination of sub-calibre FAPDS-T (Frangible Armour Piercing Discarding Sabot with Tracer) and programmable ABM (Air-Burst Ammunition).

The drive sub-systems of the gun and the optoelectronic tracking head are designed based on the advanced drive units and dedicated electronic controllers in each of axes. It provides for high dynamics and precision of movement at the same time. Inertial navigation sub-system (including GPS) ensures the guns attachment at firing position and accurate and continuous measurement of azimuth angle, angles of inclination and tilt as well.

The communication and data transmission sub-system ensures the radio and cable communication with the battery command and control system and with the WG-35 fire control vehicle while performing the transfer of data and voice. The sub-system enables remote control of the gun from a portable terminal. The above functions are executed by means of digital phones and wideband radios, among others.

The built-in optoelectronic tracking head of AG-35 gun is equipped with daylight camera, infrared camera and high repetition laser rangefinder. With these sensors, the system may perform combat operations in different weather conditions, during the day and the night.

The application of the optoelectronic tracking head and independent fire control system at the AG-35 gun enables the operation in various modes resulting from the combination of several options for target designation. They are based on acquiring the target by using its own tracking head or the tracking head of the WG-35 fire control vehicle which may obtain target designation from the SOLA or BYSTRA radar stations or, from its own portable observation post. The operation of the gun may be controlled directly from the gun, or with the use of portable terminal or remotely, from the operators post in the WG-35 fire control vehicle.

A modular design of the gun system makes it possible to integrate it with different types of wheeled or tracked platforms of sufficient loading capacity, including the self-propelled vehicles.
