Only in the 70s. appeared worthy replacement SAU, issued even during the Great Patriotic War. After the serial production of the so-called "flower series of" self-propelled Main Missile and Artillery Directorate has set new requirements for developers under which the new combat vehicle was to carry a 152-mm howitzer. It is assumed, that the artillery unit will be universal, that it can be used as self-propelled guns, and on the towed units.

Running gear intended to make the same basic chassis tanks. The main developer 2S19 appointed UZTM (ON "Uraltransmash") and the Tula Instrument Design Bureau. AT 1989 g. new ACS was put into service under the symbol 2S19 "MSTA-S" and intended to eliminate tactical nuclear weapons, artillery and mortar batteries, armored vehicles, anti-tank weapons, Air and missile defense opponent, its control points, field fortifications, as well as for the destruction of the living forces of the enemy. Self-propelled gun could fire the observed, and on unobserved targets from concealed positions, and direct fire.

The machine has an armored body, for construction and housing shaped like a T-72. Reservation weaker and protects the crew and equipment from armor-piercing bullets and shrapnel. The front housing portion is made of a homogeneous bronestali. For making tower used Rolled armor plates. It is equipped howitzer 2A64, equipped with guidance and targeting system, automated filing system and storage shells, including feed conveyor with the ground shells, laying 6ETS19 programmable issuance and executive angles coordination mechanism to feed shells laying on the weapon. The tower also located onboard unit AP-18D with an autonomous power supply system, ventilation system, means of communication, and sealing system of the manned howitzer, responsible for preventing gas contamination of the crew compartment. Only one tower without ammunition weighs about 13 500 kg.

Chassis 2S19 «MSTA-C" includes on each side by six rollers, the steering wheel with the track tension mechanism, drive wheel with removable gear rings and five supporting rollers. In the suspension used torsion shafts and rockers, similar to tank T-80. Suspension of the car independent torsion bars long. On the first, the second and sixth rollers mounted adjustable telescopic dampers, used for damping vibrations during firing of guns. 580-mm equipped with caterpillar rezinometallicheskmmi joints and rubberised jogging track.
Self-propelled gun is equipped with a U-shaped 12-cylinder high-speed four-stroke liquid-cooled diesel power 840 hp, that can run on six kinds of fuel. Eight-transmission has seven forward gears and one reverse. Electrical equipment consists of four battery voltage 27 AT.
The primary arms protrudes 152mm howitzer 2A64, the barrel having separately-loading. When shooting using high-explosive shells (FFS) ZOF45 composed shots ZVOF58, ZVOF72, ZVOFTZ, rocket-assisted projectile (ADR) ZOF61 (at a distance 28 900 m) composed ZVOF91 shot, the type of cluster munitions 3023, containing 42 anti-tank submunition (firing range 26 000 m), Staging shells active radar jammers type ZNSZO (at a distance 22 300 m), smoke bombs, target designators as part ZVDTS8 shot, and spetsboepripasov. The gun can carry out shooting all types of standard ammunition D-20 and 2SZ and guided missiles with laser illumination 30F39 "Krasnopol" within ZVOF64 shot. At the same time highlighting the objectives is made with the help of advanced artillery observers devices 1D15, 1D20, 1D22 or 1D24.
Cannon 2C19 "MSTA-C 'equipped with a semiautomatic loading system, which not only facilitates the work of the crew, but also increases the rate of 7-8 shots per minute in the case of internal munition and 6-7 rounds per minute for feeding ammunition from soil. all ammunition, located in the tower, includes 50 shots 152mm caliber, of which 20 shots and OFS 30 ADR. The gun is equipped with a recharging system, can fire at any angle pointing in the direction of elevation and its maximum rate of return without guns on the loading line. Racks have such ammunitions structure, which allows you to arrange all the regular types of shells, and searching for the right one, and control the process of loading is reproduced via the control system loading mechanism.

Delivery charges and selected shells to the gun is carried out by two independent conveyors. Shoot shells automatically ejected through the door, which is under the gun barrel, avoiding strong gassed the crew compartment. As used auxiliary arms 12.7 mm anti-aircraft gun-NSVT 12.7 "cliff", mounted on the commander's cupola as part of an anti-aircraft installation, having a remote control and a sight-ROM 7. Effective range reaches gun 2000 m, and rate - 700-800 rounds per minute at angles from the vertical guidance -3 to 70 '. Ammunition includes his five belts on 60 rounds each.
When the main motor or cause it to malfunction ACS system are secured by auxiliary energy unit power AP-18D - gas turbine power 16 kW, able to operate continuously for 8 no. The internal communication takes place using an electrical 1V116, calculated on seven subscribers. External communication is performed via VHF radio R-173 with a range of 20 km.
In addition, "MSTA-S" is equipped with an automatic fire protection system with triple action ZETS11-2 control equipment, two filtering unit, system entrenching, termodymovoy equipment, 902V system "Cloud" for shooting 81-mm smoke grenades, two tank degassing devices. Besides, on the self-propelled gun has a set of equipment for underwater driving, allowing the car to overcome water obstacles to a depth of five meters.
Usually, assault gun is a part of the battery of artillery fire complex (Cabo) "Skit" along with the battery commander machine 1B 152 "Skit-B" (on the basis of a unified chassis UNSH), senior battery officer machine 1B 153 (on the basis of "Ural-43201" with a universal body K43210) and eight units 2S19. The dog is a basic unit for forming the compounds of any artillery.
