2S35 Koalitsiya-SV Self-Propelled Howitzer

Coalition SVThe all-new 2S35-SV Koalitsiya (SV = sukhoputniye vojska) self-propelled howitzer is the successor to the 2S19 Msta-S. Although said to be based on the next-generation Armata platform, the vehicle in the 2015 Victory Day parade did not give evidence of this. The Coalition-SV's hull featured at the 2016 Victory Day parade was clearly different. While the frontal arc of the hull and crew positions appeared similar to that of the Armata, the drivetrain appeared to be that of a T-72/90, with the vehicle utilising six T-72/90 roadwheels. Coalition-SV is said to weigh 55 tonnes.

Development began much earlier, in 2006. The first two prototypes were ready in 2013, then their tests began. The following year, an experimental batch of 10 prototypes was launched on the chassis of the T-90 tank, which took part in the Victory Parade. In February 2020, it became known that the first batch of four pre-production samples on the new chassis was ready for delivery to the army. It is expected that their military tests would last until 2022. After the start of mass production, howitzers would go into service with individual artillery brigades. Perhaps these installations would be adopted by the coastal artillery of the fleet.

Tests of the wheeled version of the Coalition are also being conducted on the chassis of a KamAZ truck with an 8 * 8 wheel arrangement. He would be able to make long marches on ordinary roads without destroying their surface. The mobility of wheeled self-propelled guns in a developed road network is higher than that of traditional tracked ones. According to Dmitry Semizorov, the head of Uraltransmash, where the Coalitions are released, the Ministry of Defense is also interested in such a gun mount.

Experts have written about an initial plan to create a double-cannon version of the machine, but there was evidence to suggest that the plans were later abandoned. One of the early versions of the "Coalition" was distinguished by two 152-mm howitzer barrels. Two-barrel system of this high caliber allowed the "Coalition" to achieve unprecedented rate of fire and implement a volley mode of shooting on goal from the same gun. In this mode of firing from a gun in quick succession, the shells fired one after the other move along different trajectories and hit the target simultaneously.

According to subsequent publications, the decision to use the two-barrel system was abandoned in 2010, but the requirement to achieve a high rate of fire was preserved.

The 152-mm and 155mm caliber howitzer is capable of hitting ground targets at a distance of up to 70 kilometers using precision-guided rounds. Sources indicate that the vehicle would feature automatic targeting and charge selection.

Russia has tested a 152-mm howitzer gun "Coalition-SV", using a new principle of firing projectiles. Vasily Kashin, an expert of the Center for Analysis of Strategies and Technologies believes that Russia was seeking to create an entirely new artillery system which would fill a qualitative void observed in Russian artillery at the turn of the century.

The thermo-electro-chemical weapon uses a special high-density material instead of the conventional gunpowder, which is detonated by an electric discharge. It is reported that projectile is accelerating in the gun barrel not only by the energy of the expanding gases, but also by an electromagnetic pulse. As a result, it is possible to increase the firing range by 50%, according to the newspaper "Izvestia". These plans were later abandoned

Modern Chinese self-propelled 155-mm howitzers, such as the PLZ-05 were created by using technology acquired as a result of cooperation with the U.S. company Space Research in the 1980s. At that time, Space Research was a pioneer in the creation of heavy guns with an increased length of the barrel and a longer firing range. Experience in the creation of long-range artillery systems was combined with the success attained by Harbin plant No. 674 in the development of medium-tracked chassis of the new generation, as well as China's achievements in the field of automated artillery fire control. Finally, automated system of loading guns used by the Russian howitzer "MSTA-S" was borrowed for the Chinese self-propelled howitzers in Russia.

As a result, the new Chinese artillery systems were superior to their Russian analogues in the degree of automation and firing range. According to their characteristics the new Chinese artillery systems are comparable with the best western systems, which was demonstrated in the 2000s when China was able to sell significant quantities of their howitzers to the United Arab Emirates and Saudi Arabia. In addition, they can use correctable artillery shells "Krasnopol" manufactured under license from Russia. Therefore, Russia would now have to put in a major effort to restore its position in the artillery weapons market.

"Coalition" would have a very high level of automation that would dramatically reduce the crew (perhaps to just 2 people). The tower with weapons would be completely isolated from the crew compartment. Location of crew members in a separate armored capsule would provide a higher security. It is also expected that the system would have a high rate of fire and its range would be increased up to 70 kilometers. Track version of the system is likely to be based on the prospective Russian heavy crawler created under the project "Armata". The caterpillar propeller of the suspension system consists of 12 road wheels with torsion bar suspension and additional hydraulic shock absorbers for the front and rear rollers, the total weight of which is 8.7 tons. The aft location of the engine-transmission compartment, which requires a long kinematic connection in the form of a lever system located on both sides of the chassis for the entire length of the machine up to the driver's control levers.

The "Coalition-SV" is known for a number of features. The new principle of firing a projectile is only one of them. Russia is seeking to create an entirely new artillery system, which would eliminate the qualitative lag in the Russian artillery system that began with the collapse of the Soviet Union. The artillery systems used today by the Russian Army are inferior not only to the best Western models, but also to the Chinese systems.

A single Russian state-of-the-art Koalitsiya-SV self-propelled gun is worth an entire artillery battery, deputy commander of Russia’s Missile Troops and Artillery, Major-General Alexander Dragovalovsky told the press 22 November 2015. "It’s a new weapon, cutting edge. Its capabilities effectively allow it to replace a whole battery," Dragovalovsky said.

Due to its pneumatic loader and microwave shell priming system, the Koalitsiya-SV is capable of firing up to 16 shells per minute [Compared to the Amerian M109A6 Paladin maximum Rate of Fire of 4 rounds / minute for 3 minutes]. Its ammunition capacity is 50-70 shells, including precision-guided munitions linked to the GLONASS system, Russia's equivalent of the US-based GPS satellite network.

The first batch of serial 152-mm self-propelled artillery units (SAU) of new generation 2S35 NW Coalition hit part of the Russian army. While the military had called the number of machines that must be produced at the new chassis Armata (pilot batch was based on the T-90). With the new SAU army receives more than 30 self-propelled artillery systems Msta-SEE.

It is worth noting that the Coalition-NE is not upgrade version of any of the Soviet self-propelled artillery of the previous generation, which is kind of revolutionary for the Russian army fighting machines. In addition to the latest 2A88 equipment with unique by world standards at a rate of up to 16 rounds per minute (data channel "Star"), it is equipped with advanced electronic equipment and integrated in the information battle system management tactical level.

Russian artillery would learn to hit targets at a distance of over 100 km. Ultra-long-range guided missiles would soon replenish the ammunition of the Coalition and Msta installations. Until now, the maximum range of the corrected ammunition has not exceeded 20 km. The increased range would allow conventional self-propelled guns to hit the most important objects - command posts, headquarters, airfields, communication centers and bridges in the rear of the enemy. The novelty would radically increase the capabilities of the ground forces, experts say.

According to Izvestia sources, reported 05 March 2020, the military-industrial complex was working on several versions of ultra-long-range shells for the latest 2S35 Coalition-SV howitzer. The interlocutors of the publication refused to name the exact deadlines, but explained that the development would be submitted for testing in the near future. Unique ammunition would allow the Coalition to deliver high-precision strikes at a distance of over 100 km. New items would also replenish the ammunition of the Msta howitzers.

The development of ultra-long-range shells is also led by the Pentagon. To increase the capabilities of conventional field artillery, the United States plans to create a new gun under the designation ERCA (Extended-range cannon) and ammunition for it. With the active-reactive XM113, the upgraded M109A7 self-propelled howitzers should have a range of 40 km. And with an elongated barrel and a prospective projectile equipped with a ramjet engine, the distance would increase to more than 100 km.

One of the projects of ultra-long-range ammunition is a telescopic guided missile with a direct-flow rocket engine. Currently, research is already underway to create an exotic ammunition that unfolds in flight like a spyglass. Such a transformation allows to improve the characteristics of the built-in engine and radically increase the range compared to the traditional design.

Now the most massive Russian guided artillery shell "Krasnopol" has a maximum range of 20 km. The "coalition" with new high-precision ammunition would be able to hit objects with single shots even in the deep rear of the enemy. With them, she would solve combat missions that operational-tactical missiles used to cope with. “The target can be highlighted from a drone,” military expert Viktor Murakhovsky told Izvestia. “But there are other technical solutions that can achieve high accuracy.” In this area, we would be on a par with the most advanced developments of Western countries.

The main purpose of the guided ["corrected"] ammunition is to defeat particularly important targets in the tactical depth: command posts, communication centers, launch positions of missiles, airfields, helicopter jump sites, the expert added. “Now there are no long-range weapons of destruction at the level of the division corps,” said Viktor Murakhovsky. - In Soviet times, each division had a division with Tochka missile systems, but now such means are not provided for in the regular structure of formations. As a result, the commander does not have at hand the fire weapons capable of hitting targets to the full depth in his area of responsibility. The general has to turn to the senior boss for help, and there is no guarantee that she can always be provided. Unlike ballistic missiles, an artillery shell cannot be intercepted by air defense systems. His flying time is less. Ammunition arrives completely suddenly, not giving the enemy time to take cover or move.

Guided 152-mm shells cause less collateral damage than heavy aerial bombs, which is especially important when fighting in densely populated areas. With a high-precision hit, when the deviation is less than a meter, ammunition of this caliber is enough to destroy most objects on the battlefield. According to the developers, the new models of heavy and medium Russian drones can be equipped with powerful laser rangefinders, target designators. This would make it possible to use them in the role of gunners for existing and new long-range guided projectiles even at the maximum firing distance of howitzers.
