A bulldozer-type blade is standard and allows the 2S19 crew to dig out their own emplacement prior to firing. The crew is afforded a full NBC (Nuclear, Biological, Chemical) suite while the driver has access to a passive night vision system. The driver is the only crewmember separated from the rest of the group, taking a position in the front-center of the hull. Crew accommodations amount to five personnel including the driver, vehicle commander, gunner, loader and charge manager. When in transport mode, the barrel is affixed to a inverse "Vee" type assembly to lock the barrel in place. A fume extractor is identified at the barrel's midway point. The turret overhangs the bow of the hull and is capped by a double-baffle muzzle brake. The turret houses the gunnery crew as well as the main gun and recoil mechanism needed to contain the violent recoil of such a large-caliber weapon system. It features a low-profile chassis and hull structure straddled by long-running track systems while its primary armament is set within a large, boxy turret emplacement fitted to the middle rear of the hull roof. Outwardly, the 2S9 vehicle promotes a rather conventional appearance as modern self-propelled artillery systems go. Service entry was noted in 1989 with the introduction of the 2S19 MSTA-S ("S" marking the self-propelled version of the gun, the alternative being "MSTA-B" to designate towed versions of the same gun in field form). After clearing all requisite field evaluations, the pilot vehicle emerged in production form as the 2S19 MSTA (MSTA translating to "Mobile Self-Propelled Heavy Artillery" in the Russian). Interestingly, the inherent T-80 engine was dropped in favor of the powerplant as utilized by the T-72 Main Battle Tank series. Design work began in 1985 and the pilot vehicle (prototype), known under the designation of "Obyekt 317" ("Object 317"), soon appeared, built upon the chassis of the proven T-80 Main Battle Tank. The 2S19 system originated form an attempt by the Russian Army to modernize its self-propelled artillery reach in the 1980s. Hundreds of 2S19 units have been delivered since the type's inception with foreign operators being mainly nations maintaining close diplomatic ties with Russia. The vehicle is similar in design, scope and function to contemporary Western designs including the American M109 and British AS90 series of tracked gun platforms. The 2S19 MSTA is the primary self-propelled artillery system of the Russian Army today, fielding a powerful 152mm main gun able to fire varying forms of projectiles at extensive ranges.
