What is the most powerful Pion self-propelled gun in the world used in Ukraine?

To eliminate the fortified areas of the army of the armed forces of Ukraine today, 203-mm self-propelled guns SAU 2S7 “Pion” are used. This high power system with more than half a century of history today demonstrates high efficiency in the destruction of powerful fortifications.

The main goals of the “Pions” are important enemy targets in tactical depth, the maximum firing range is 47.5 km. Due to the enormous power of 203-mm projectiles, these weapons can be used to destroy almost all types of objects. Its characteristics make it possible to destroy buried command posts, communication centers, positions of artillery and tactical missiles, helipads, ammunition depots and fuel and lubricants. At the same time, “Peony” difficult to destroy with return fire, the gun has a fairly high mobility for its mass. This long-range self-propelled gun can fire 1-2 shots and leave the firing position even before the first shell hits the target. Maximum speed on highway — 51 km/h, power reserve — 500 km.

Guidance and loading

Initially, to aim the gun, the gunner's station was equipped with a PG-1M panoramic artillery sight for firing from closed firing positions and a direct-fire sight OP4M-99A for firing at observed targets. To monitor the terrain, the control department is equipped with seven TNPO-160 prism periscopic observation devices, two more TNPO-160 devices are installed in the hatch covers of the calculation department. After the modernization, the electronics were updated, which significantly increased the performance characteristics of the gun. The self-propelled guns received new communication, control, guidance and control devices. Digital information is now processed automatically, which has improved the process of detection and targeting.

The loading of the main gun during the operation of the self-propelled guns is carried out from the ground or from a truck with the help of a special lifting mechanism installed on platform, from the right side relative to the main gun.

Combat Performance

At today, SAU 2S7 “Peony” is the most powerful self-propelled artillery installation in the world. It is in armament of Russia and a number of other countries of the former USSR. Combat Weight — 46 tons, crew — 7 people. The chassis body is a welded structure, which is divided by transverse partitions into four compartments: control, power, calculation and aft. On the march, the commander, gunner and driver are in the cockpit of the self-propelled guns (control department). The remaining four crew members are located in the middle compartment of the unit.

Armament of self-propelled guns — 203 mm gun 2A44. In the vertical plane, the gun is aimed within ranges from 0 to +60 degrees, and the horizontal pointing angle is plus or minus 15 degrees. B & nbsp; Ammunition “Peony” includes OF43 high-explosive fragmentation projectiles, as well as an active-rocket projectile. OF-43 weighs 110 kg, the projectile contained 17.8 kg of explosive. The maximum firing range of a high-explosive fragmentation projectile was 37.5 km. The active-rocket projectile weighed 103 kg, it contains 13.8 kg of explosive, the firing range of this ammunition was a record for its time and was 47.5 km. Also “Peony” can use concrete-piercing projectile, chemical projectile and special munition with nuclear charge.

History

Development of self-propelled gun 2S7 “Peony” began in 1967  In 1975, it was put into armament and serially produced until 1985 . From 1986 to 1990, a modernized version of the 2S7M Malka self-propelled gun was produced. In total, more than 500 artillery giants have been created. The gun was intended for the destruction of individual remote especially important objects, the destruction of fortifications and strikes with special ammunition with a nuclear charge.
