203-mm self-propelled gun 2S7 (object 216) refers to the weapon of the artillery reserve of the Supreme command. In the army she received the code name - SAU “Flowers”. Photo listed in this article showcase the power of this tool. It is intended for suppression of means of nuclear weapons and other important objects in the tactical depth (distance 47 km).sau pion

History

The Establishment of SAU “Peony" began with the decision of the Council of Ministers of the Soviet Union from 1967. In the task indicated that the new weapon was supposed to destroy the earth, concrete and reinforced concrete fortifications, and to destroy long-range artillery of the enemy. In addition, SAU “Flowers” 2S7 is designed as a “hunter” for tactical missile systems and other means of delivering nuclear warheads. According to the task, the minimum range was supposed to be 25 km.

And now, after two years of several proposed projects, the Council of Ministers has chosen the work of designers of the Leningrad Kirov plant. Installation of "Peony" established on the base chassis of tank T-64 with an open chopping performance. However, in the same year the work on creation of a new weapon are significant changes. The reason was the presentation of the designers of the Volgograd plant "Barricades", which presented its project of self-propelled artillery in the open execution on the basis of the object 429. In the end, the Ministry of defence decides on the Association of these developments, and self-propelled 203-mm "Peony" transplanted to a new chassis. This artillery had a range of up to 32 km of conventional ammunition and 42 km rocket-assisted warheads. Work on the creation of long-range guns was in full swing, when in March 1971 GRAU claims specified requirements for performance characteristics of the designed system. The engineers were asked to study the possibility of using a special shot from ЗВБ2 howitzer B-4 with the same caliber. The maximum firing range conventional 110-pound shells were set to 35 km, and the minimum guaranteed basicosta – 8.5 km and the Greatest distance of firing special rocket-assisted ammunition was to be 40-43 km away. All these changes fell on the shoulders of the main developer SAU “Flowers” 2S7 – COB № 3 Kirov factory, the head of which was N. S. Popov.

Creation tools

At the same time, plant engineers "Barricades" under the leadership of chief designer G. I. Sergeeva developed artillery installation of ACS “Flowers”. Rotor designed a warhead according to the classical scheme, but with a number of features. For example, an interesting solution was a collapsible barrel (the classic is considered a monoblock design). It consisted of a breech, the pivot pipe, couplings, sleeve and casing. The author of this design is the engineer of the Obukhov plant A. A. Kolokoltsov, who developed it in the seventies of the last century. The choice of this solution is due to the fact that the artillery fighting technique is increased power (which is “Flowers”) is subject to very rapid deterioration of the rifled part of the barrel when shooting. As a result, the monoblocks that were in disrepair, should be sent for replacement to the factory, which requires a significant investment of time. All this leads to the conclusion of building this setup for a long time. Portable the trunks are also prone to rapid wear, but the replacement process is quite feasible in a gun shop, located in the frontal area, it does not require specific equipment and is relatively simple.sau 2S7 pion

“the God of war with nuclear Goodies”

Is a nickname received a new artillery system, when in 1975 it was presented to the designers of the Leningrad plant. The Ministry of defence immediately appreciated the new ACS. And after a series of factory and field tests of the expert Committee gave its approval to the adoption of its weapons and start serial production. In the same year the first copies go to the troops. New weapons manned artillery brigade of special power, and it was intended to suppress and eliminate artillery, nuclear weapons, mortars, heavy equipment, logistics, manpower, command posts. Eight years later, in 1983, setting “Flowers” has been the first upgrade. The updated model received the code name – “Malka”. GRAU index remained the same, only with a note: “M”-2С7М. It's safe to say that Soviet engineers with their design ahead of time, it's been almost 40 years since the release of the first “Peony", but this does not prevent him to remain to this day the most powerful and popular artillery in the world. According to official figures, since 1975, has issued more than 300 units of this weapon. After the collapse of the Soviet Union, many complexes have been abroad, but continue to properly serve in the armies of the countries of the former USSR. According to the Ministry of defense, as of 2010 year in the Russian army there were 130 units of ACS “Flowers”. To understand what is the uniqueness of this artillery system and why, despitethe emergence of new types of long-range weapons, modern weapons of the Russian army includes these war machines of a bygone era, consider the technical characteristics of the installation.

Description of the design of the artillery complex “Flowers”

As mentioned above, SAU “Flowers” styled with an open chopping part, that is, on the reckless scheme. Gun setup posted openly in the aft crawler. In front of the body compartment control, then placed the engine-transmission compartment, followed by the separation of the calculation and closes the combat tower. Armored body has a very unusual shape - made far-forward cockpit serves as an additional counterweight heavy weapon. Service artillery "Peony" by a team of fourteen people, seven of them – the crew ACS. In the stowed position the crew is in the compartments of calculation and control, and the remaining seven people are in a truck or armored personnel carrier.installation peony

At the rear of the housing is mounted a powerful gun, 203 mm (2А44), whose mass is 14.6 tons. Besides that the tool created a collapsible, it has an additional number of innovations. For example, a constructive rejection of the use of a muzzle brake muzzle has provided a wave of low pressure in the working area of calculation. This decision has allowed to refuse additional special protection for the maintenance calculation. 203-mm gun equipped with a piston valve operating in push pull circuit. It opens and closes automatically, mechanically, it is possible to perform this operation manually. In ACS "Peony" flow with the subsequent sending of the shells is carried out using a special chain loading mechanism operating at any angles horizontal and vertical guidance. This design decision will significantly reduce the recharge time, thereby increased the rate of fire of the complex.

Powertrain and chassis ACS

The Most powerful self-propelled artillery in the world equipped with a twelve-cylinder V-shaped diesel power unit-46-1 equipped with a turbocharger system. The engine power is 750 HP, the Use of this power unit allowed a 46-ton vehicle to accelerate to a speed of 50 km/h. in addition, to provide Autonomous work in the engine-transmission compartment is installed an additional diesel generator with a capacity of 24 HP With the aim of increasing harmonization manual transmission with bevel gearbox and side gearbox was borrowed from the T-72. So, self-propelled unit has a mechanical planetary power transmission with eight speeds and a single-stage on-Board with lowering the gears.

The suspension on both sides of the body installed by seven road wheels with torsion bar type suspension with individual locking hydraulic shock absorbers. Many components of the chassis borrowed from the T-80. In fact, chassis, SAU “Purple” is a modernized version of the chassis of tank T-80, even the driving wheels have a front location. sau 203 mm pion

Fire

The Operation of loading a weapon carried by a special panel, the supply of shells is made with the help of standard single-axle handcarts. When pointing the guns used mechanical and electro-hydraulic actuators. The rate of fire artillery system “Purple” is one and a half shots per minute. The unit has the following modes of fire: 8 rounds in 5 minutes; 15 shots in 10 minutes; 24 shots in 20 minutes; 30 shots in 30 minutes, and 40 shots within an hour. On the barrel in the upper and lower parts are hydropneumatic recoil mechanisms. Length of recoil of gun is about 1400 mm. Given the huge capacity of the plant, the engineers have provided special guides, which are located in the aft part of the body. They are installed directly in front of the fire on the ground, play the role of auxiliary supports. In addition to repay very noticeable recoil in the aft body mounted Coulter bulldozer type. It is operated by a hydraulic actuator. During firing the opener deep into the soil to a depth of 700 mm, thereby providing a self-propelled installation excellent stability. In addition, to absorb the force rollback the designers have provided a locking system gidrohlortiazidom hardpoints main rollers tracked chassis and lowerable guide wheels.

Through the use of a highly effective recoil mechanisms, firing of guns may be carried out in a wide range of pointing angle. So, the angle information, the horizontal is 30 degrees, and in a vertical plane in the range from 0 to 60 degrees.

In the case when firing takes place from the soil, a calculation can use a two-wheeled cart, on which the charges and shells are placed on a special removable stretcher. Ammunition artillery "Peony" of 40 rounds of separate loading ammunition. Four of them are stored in the aft compartment and provide an emergency reserve, and the rest are transported on special vehicles and laid on the ground withthe preparation of ACS to fire.

Armament

The Range of ammunition "Peony" is very diverse: 203-mm shells ЗВОФ42 and ЗВОФ43, fragmentation 30Ф43, active-reactive high-explosive ЗОФ44, ЗВОФ15 and ЗВОФ16 with fragmentation warheads with submunitions 3-0-14. Military equipment "Peony" equipped with a mechanical sight type D-726, collimator K-1, panorama PG-1M. In addition, there is an additional sighting device type OP-4M used in the conduct of direct fire. To protect ACS and people, the unit is equipped with and personal weapons of the crew: this includes missile weapons (four rifles and a flare gun), and handheld anti-tank RPG-7 rocket launchers, MANPADS, "Strela-2”, as well as grenades f-1.Museum of artillery

Nuclear weapons and protection

Artillery self-propelled gun "Peony" able to participate in armed conflicts with the use of nuclear weapons. To do this, ACS has the filtration installation, automatic sprinkler system, the containment system of the crew compartments that can protect the crew and the calculation of the nuclear, bacteriological and chemical weapons. In addition, it is equipped with equipment for the internal telephone, radio and night vision device. For the application of atomic attack the enemy ACS “Flowers” could use special munitions with nuclear warheads. The use of such shells is only possible with the appropriate order from a superior command. In this case the ammunition to the firing positions are delivered to special warehouses in the composition of the protected convoy. A nuclear missile designed to destroy especially large infrastructure, industrial facilities, concentrations of enemy troops etc. the Minimum and range of such ammunition is 18 km, and the maximum is 30 km away.

Self-Propelled artillery 2С7М “Malka”

In 1983, KB № 3 Kirov factory has upgraded the installation of “Flowers”. The result is an updated model differs from its predecessor, rubber chassis parts, in addition, the chassis were made of more durable materials. In the complex control system there is a new instrument of fire, is able to receive information automatically. In addition, engineers have improved the remote loading mechanism and changed the design of the charger styling. Introduced new weapons and ammunition increased power and emergency supply of shells was increased to eight units. The updated ammunition entered active-reactive shells. In addition, SAU “Malka” established a system of regulated control of continuous operation with an automatic diagnostic system for all key subsystems artillery.Russian artillery

The Improvement of chassis allowed to increase the resource of motocross to ten thousand kilometers. Thanks to the modernization of the remote device loader installed, this procedure is made possible at any angle vertical lay. In addition, significantly increased the rate of complex (1.6 times) – up to 2.5 rounds per minute, and the time of continuous firing amounted to three hours. The option of fire control with automatic reception of the data allowed to obtain the coordinates of the targets via wired and radio communication means and then displays them on digital indicators devices gunner and commander, with the leads themselves takes into account changing weather conditions. The updated ammunition entered active-reactive shells, the firing range which was 55 km away, as well as high-precision and anti-tank ammo with ramjet aircraft jet engines.

Today, SAU “Flowers” and “we” have great potential for further modernization, they are able to keep up with the times and use his Arsenal of modern weaponry, including tactical and precision weapons.

Saint Petersburg: Saint Petersburg artillery Museum

This institution was founded in 1703 by decree of Peter the First as Arsenal – storage of the funny and memorable pieces of artillery. Here from all over the country were brought the most valuable and interesting specimens. Late in the exposition began to add other types of weapons, banners, uniforms, including the trophy. Later, during the reign of Elizabeth, the artillery Museum was renamed in the Memorable hall and was placed in the casting yard. And only since 1869 that the institution began to actively live and develop. This year the Museum of artillery has at its disposal part of the building of the Kronwerk, there are military-historical collection. During the Soviet Union, in 1963, the institution receives the funds of the Central historical military engineers Museum, and two years later, it includes the Military Museum of communications.the Petersburg Museum of artillery

Visitors are invited to see the rare collections of world weapons from 55 countries, ranging from the fourteenth century to the present day. Here you can see among the exhibits of the personal weapons of members of the Imperial family, great generals, unique documents, military awards, military uniforms, models of fortificationbuildings and FORTS and much more. A separate exposition is presented by the Russian artillery, including experimental models of guns Shuvalova, state University and others.

Military historical Museum of artillery, engineer and signal corps is one of the largest in the country Assembly of weapons of the Western European countries of the XV-XVII centuries. In 2006 the school opened a new exhibit dedicated to the history of warfare the middle Ages, Renaissance and early modern period. Artillery Museum enjoy visiting both adults and children, here in the courtyard of Catherine the modern weapons of the Russian army, such as Intercontinental strategic missile, the rolling ground-based "poplar" of the RS-12M and many others. Guests can not only see, but also touch their hands, to be photographed next to such giants, serving as a guarantor of security of our country from external invasion. Because most students have a superficial familiarity with such weapons as guns, tanks, armored cars, artillery gun, which they get from computer games and television films. Seeing them firsthand, feeling the power of their armor and weapons, they forever imbued with respect not only to the profession of the military, but also to the designers who created these wonderful machines. Children and adults will be interesting to visit and festivals of military-historical reconstruction, and demonstrations by members of the Club of historical fencing “Silhouette”, which are regularly held at the Museum. So an unforgettable experience to visitors of the Museum guaranteed.
