ZUZANA 2 artillery system design and features
The ZUZANA 2 self propelled autonomous howitzer is mounted on a TATRA 8x8 special chassis. The chassis offers enhanced mobility and long range.
DANA-M1 CZ is a modernised version of vz. 77 DANA (Delo Automobilní Nabíjené Automaticky) 152mm self-propelled wheeled howitzer developed by Excalibur Army to provide effective artillery support for the Czech Army.
The vehicle has a maximum length of 14.2m, height of 3.52m and width of 3.02m. The crew compartment accommodates up to four personnel and is equipped with an air conditioning system to reduce crew fatigue.
The vehicle incorporates an automatic fire-extinguisher system for internal fire safety. A power supply unit is also installed to provide energy to the turret and chassis aggregates when the engine is turned off.
Armament of ZUZANA 2 howitzer
The main armament is 155mm/52 calibre gun, which is 8.2m-long and weighs 1,894kg. It can fire six 155mm Nato projectiles per minute in automatic mode and two rounds per minute in manual mode. It offers a minimum firing range of 5km and a maximum range of 41km with ERFB-BB shells.
The gun offers high firing accuracy and can be rotated through -3.5° / +70° in elevation angle and through ± 60° in traverse angle.
The artillery system features both direct and indirect firing capabilities and can carry up to 40 ready-to-fire projectiles and 40 powder charges in the conveyers. The conveyers can carry new types of projectiles of 1m length and can also load them into the gun automatically. The turret incorporates four smoke grenade launchers on each side for greater survivability.
The ZUZANA 2 artillery system offers superior protection for the crew against nuclear, biological and chemical (NBC) weapons, mounted weapons, small arms, and ammunition fragments.
The weapon mounts are provided with ballistic protection against the direct fire and the fire at ± 30° angles, meeting the STANAG 4569 Level 4 standard.
