2A36 Giatsint-B (M1976) 152-mm Towed Gun
The 2A36 (M1976) 152-mm Towed Gun has a distinctive four-wheeled carriage and armored shield slopeing to the rear and extending over the wheels. The 49-caliber barrel features a multi-slotted muzzle brake, with the recoil system mounted above the ordnance towards the rear. Elevation and traverse is manual with the former being from -2° 30' to +57° with traverse being 25° left and right.
First observed being towed by the new KrAZ-260 6x6 truck, the 2A36 can also be towed by the KrAZ-255B 6x6 truck or ATT, ATS or ATS-59 full tracked vehicles. The four rubber-tire wheels provide for high speed road-towing as well as for improved cross-country mobility. In firing position the 2A36 is supported on a circular jack under the carriage and on the trails, which are equiped with spades.
The quick firing load assist system includes a hydraulic rammer, by which a projectile placed on the loading tray is rammed into the ordnance. The cartridge cased charge is loaded in a similar manner, and once the breech is closed and the rammer returns to the side the weapon is ready to fire. The system is capable of a sustained rate of fire of six rounds a minute, and an entire battery can put almost one ton of ammunition onto a target in one minute.
The ammunition system used by the 152 mm 2A36 is of a new design that is not inter-operable with earlier artillery systems such as the 152 mm 2S3. Separate loading ammunition includes high explosive fragmentation (HE-FRAG) and armor-piercing tracer (AP-T). The former weighs 46 kg and has a maximum muzzle velocity, using the top charge, of about 800 m/s. The AP-T round is used in the direct fire mode against armored vehicles. The standard HE-FRAG projectile has a maximum range of 27000 meters, and a rocket-assisted HE-FRAG projectile can also be fired to a maximum range of 40000 meters. Other projectile include chemical, smoke, concrete piercing, incendiary and tactical nuclear.
