2S35 Koalitsiya-SV 152mm Self-Propelled Howitzer, Russia
2S35 Koalitsiya-SV is a latest 152mm self-propelled howitzer from JSC Central Research Institute Burevestnik (Petrel), a division of Uralvagonzavod based in Nizhny Novgorod. Development on the howitzer began in 2006.
A Koalitsiya-SV prototype, mounted on a modified T-72/90 tracked chassis, was unveiled during the Victory Day military parade in Moscow in May 2015.
The first batch of 12 units was delivered to the Russian Armed Forces in March 2015. The Russian Army's Western Military District (ZVO) artillery units are expected to receive 2S35 Koalitsiya-SV weapon systems in 2016.
The self-propelled howitzer is designed to defeat armoured vehicles, tanks, tactical nuclear weapons, anti-tank weapons, artillery and mortar batteries, enemy manpower and equipment, facilities, air defence missile systems, as well as command and control centres.
2S35 Koalitsiya-SV design
The 2S35 Koalitsiya-SV is a successor to the 2S33 Msta-SM, an improved version of the 152mm 2S19 MSTA-S self-propelled howitzer. It can be mounted on tracked chassis such as T-72/90 tank and T-14 Armata main battle tank, as well as on 8x8 wheeled platforms.
The howitzer is operated by three crew members, the driver, gunner and commander. The driver is seated in the centre in the middle of the hull, while gunner and commander are seated on either side. Three hatches are provided for emergency exit of the crew. The all-welded steel hull offers protection from mines, small arms fire and shell splinters.
Features of the howitzer include warning receiver, night vision, microwave shell priming system, nuclear, biological and chemical (NBC) protection system, and shock absorber.
Armament and self-protection
The primary weapon is a 152mm 2A88 cannon, equipped with a muzzle brake and a recoil system. Ammunition capacity of the self-propelled gun is 50 to 70 shells and the maximum firing range is approximately 70km. An automatic loader with pneumatic rammer allows the cannon to fire up to eight rounds a minute.
The self-propelled gun is capable of firing a variety of munitions such as high-explosive precision-guided munitions, jammer carrying projectiles, cluster projectiles with anti-tank sub munitions, as well as standard and rocket-assisted high explosive-fragmentation (HE-FRAG) projectiles.
It can also fire 9K25 Krasnopol semi-automatic laser-guided projectile, which can reach up to a range of 20km. The projectile has four movable control surfaces at the front and four foldable fixed fins at the rear.
A remote-controlled weapon system, armed with a 12.7mm Kord machine gun, is mounted on the top of the vehicle. Also equipped with smoke grenade dischargers, the turret offers self-defence against air and ground targets.
The export variant will feature a 155mm calibre self-propelled gun.
Artillery fire control system
The Koalitsiya-SV artillery system can fire autonomously or can be remotely operated using an integrated fire control system. The howitzer's location and firing information are displayed on the command and control panel.
55t vehicle performance
The 55t vehicle is equipped with torsion bar suspension system with six road wheels on either side. It is powered by a diesel engine, located at the rear of the hull. The running gear includes idler in front, drive sprocket at the rear, and five track-return rollers. The speed of the vehicle is 60km/h and the operational range is 500km.
The self-propelled artillery system provides high accuracy, rate of fire and long-range capabilities during combat operations.
