The Zuzana 2
is a recent Slovak self-propelled howitzer. It was developed by Konstrukta Defence. It is an
new
version of the original
Zuzana.
It is armed with a new 52-caliber
gun and has a longer firing range. This artillery system also has a redesigned forward
control cab and a number of other improvements. The Zuzana XA1 prototype
was first publicly revealed in 2008. Later this artillery system was renamed
from Zuzana A1 to Zuzana 2.
Currently it is among the most advanced artillery systems in the
world.
Unlike many
self-propelled howitzers, the Zuzana 2 is based on an armored 8x8 wheeled chassis. Such chassis is less expensive to build and to maintain
comparing with tracked chassis.
The Zuzana 2
is armed with a turret-mounted 155 mm/L52 gun-howitzer. The gun is
mounted externally between two separated compartments of the turret.
In this way the crew is completely isolated from potentially
dangerous gun and autoloader mechanisms and is protected from the
powder gasses generated during firing. Turret traverse is 360°,
however firing envelope is limited to 60°.
The Zuzana 2
fires all standard NATO 155 mm rounds. This self-propelled
gun-howitzer is capable of both direct and indirect firing.
The Zuzana 2 can carry 3 main types of ammunition, including standard
high-explosive rounds, extended-range high-explosive rounds and
high-explosive anti-tank rounds for direct firing at an armored
targets. Range of fire depends on projectile and charge combination.
Maximum range of fire is
41 km with rocket-assisted projectile.
This
artillery system fitted with an autoloader. Rounds are fed automatically.
It loads shells and charges at any elevation.
A total of 40 rounds are carried by this artillery system.
Ammunition is stored in conveyors. Beds in conveyers are universal
for all 155 mm projectiles and charges. There is a fuze setter for
automatic setting of electronic fuzes.
This
artillery system can automatically launch 6 rounds within the first
minute, or 16 rounds within 3 minutes. Manual rate of fire is
reduced to 2 rounds per minute. Sustained rate of fire is around 1.5
rounds per minute.
This
artillery system is capable of Multiple Round Simultaneous Impact
Firing (MRSI). It
can launch a couple of projectiles at different trajectories in
order for them to hit the target simultaneously.
The Zuzana 2
has an automatic gun-laying mode. Firing data is calculated by the
onboard computer and the gun is laid on the target automatically.
Vehicle is fitted with navigation system. Onboard fire control
system allows to operate with digital maps.
There is also a roof-mounted 12.7 mm machine gun for self-defense.
Armor of the Zuzana
2 provides protection against small arms fire and artillery
shell splinters. Front arc withstands hits from 14.5 mm
armor-piercing rounds. Vehicle is fitted with NBC protection and
automatic fire extinguishing system.
This artillery system has quick preparation for firing and brief
redeployment time. Hydraulic stabilizers are lowered into the ground
before firing.
The Zuzana 2
is operated by a crew of 4, including commander, gunner, loader and
driver. This system has a
high level of automation.
This
artillery system uses a special 8x8 chassis developed by Tatra.
Vehicle has a new powerpack. It is powered by a
new and significantly more powerful Tatra T3B-928.70 turbocharged
diesel engine, developing 442 hp. A prototype was powered by a MAN D28 76 LF
diesel engine, developing 453 hp. Engine is located at the rear. It
is mated to a Tatra 10-speed gearbox. Vehicle is fitted with a
central tyre inflation system. However it has inferior cross-country
performance comparing to that of tracked vehicles. Turret is fitted
with independent auxiliary power unit, which powers all systems when
the main engine is turned off.
Normally a battery of Zuzana
2s would be supported by a fire control vehicle. Also there is an ammunition supply vehicle
with an armored cab,
based on Tatra 8x8 military truck. However, if required, each Zuzana
2 can operate on its own.
Variants
Diana
is a 155 mm
tracked self-propelled howitzer. It is armed with a new 55-caliber
gun. The turret is mounted on a Polish tracked chassis, that uses
many components of the
T-72 tank. It is powered by an S-12U engine,
developing 820 hp. A prototype was first publicly revealed in 2015.
This artillery system was aimed at an Indian Army requirement, but
is also proposed for other possible customers.
