152mm 2S19 MSTA-S SELF-PROPELLED HOWITZER
||Designed to defeat unsheltered and covered manpower, weapons and war
materiel of the enemy to division (army) mission depth.
The self-propelled howitzer is made as a typical turreted mount and
based on a newly developed chassis, with assemblies and members unified
with main tanks.
The ammunition and gun loading, laying and retargeting processes are
To minimize gas content during sustained firing, the weapon is separated
from the crew by means of a jacket wherefrom fired cases are ejected automatically.
The howitzer is provided with an autonomous gas-turbine auxiliary power
| The 2S19 is based on a full tracked MBT
chassis with the driver at the front, fully enclosed turret in the center
and powerpack at the rear and in many respects is similar to the French
155-mm GCT self-propelled artillery system based on an AMX-30 MBT chassis.
The hull and turret is of all-welded steel armor construction which provides
protection from small arms fire, shell splinters and mines. The 2S19 self-propelled
artillery system is based on the chassis of the T-80 MBT but with automotive
components of the T-72 MBT as the 2S19 has a distinct exhaust outlet on
the left side that is not on the T-80 which is powered by a gas-turbine
engine. Mounted under the nose of the vehicle, in a similar manner to that
of the T-72/T-80 MBT's, is a dozer blade that can be used to prepare fire
positions or clear obstacles. The suspension is of the torsion bar type
with six road wheels, idler at the front, drive sprocket at the rear and
track-return rollers with the upper part of the track being covered by
a skirt. The vehicle commander is seated on the right and operates the
roof-mounted 12.7-mm machine gun that can be operated by remote-control
and the searchlight. The 12.7-mm machine gun can be used to engage both
ground and air targets. Mounted externally on the right side of the turret
are boxes of 12.7-mm machine gun ammunition for ready use. Main armament
comprises a long-barreled 152-mm gun fitted with a fume extractor and a
muzzle brake. When the 2S19 is traveling the ordnance is held in position
by a traveling lock mounted on the glacis plate. The 152-mm gun fires an
HE-FRAG (high explosive fragmentation) projectile to a maximum range of
24700 m, although using an extended-range projectile its range is probably
36000 m. Other types of projectile can also be fired including illuminating,
incendiary, smoke and tactical nuclear. Automation of the loading process
enables a maximum rate of fire of 8 rds/min to be achieved using onboard
ammunition and 6 to 7 rds/min using projectiles and charges from the ground.
This selects and then places the fused projectile into the breech with
the charges being loaded semi-automatically. In addition to selecting the
projectile from the magazine, the automatic loading mechanism controls
the number of rounds to be fired and has built-in test equipment. Laying
in elevation is automatic with laying in traverse being semi-automatic.
A total of 50 projectiles and charges is carried. Spades are not required
on the 2S19 as it is very stable when in the firing position. If required
the 2S19 can be reloaded through the turret rear while the system is firing.
This enables the system to move off to its next fire position with a full
load of ammunition on board. Three smoke dischargers are mounted either
side of the turret. A 16 kW autonomous gas-turbine auxiliary power unit
(APU) is provided in the turret and this provides power within 30 to 60
seconds of being switched on. This allows the system to be fully operational
at temperatures ranging from -50 to +50°C with the main diesel engine being
switched off to conserve fuel supplies. Standard equipment includes an
NBC system and night vision equipment for the driver.
