NEW – June 7, 2022
During the special operation in Ukraine, the Ministry of Defence of the Russian Federation used a number of new developments. It is the technical superiority that provides the possibility of offensive operations of the Armed Forces of the Russian Federation in the absence of a numerical advantage in Ukraine.
The Russian Armed Forces are using a full artillery arsenal during the special operation in Ukraine, among which the self-propelled artillery installation “Koalitsiya-SV” stands out. These are self-propelled guns with an unusually long barrel. The German super cannon “Dora”, which participated in World War II, had approximately the same “profile”.
According to the plans of the Ministry of Defence of the Russian Federation, the state tests of the improved version of “Koalitsiya-SV” and the final testing of the self-propelled gun should be completed only at the end of September 2022. But plans have changed somewhat, and it was decided to check the “future of the artillery of the ground forces,” as this self-propelled gun is called, they now.
“Koalitsiya-SV” is fully automated. This means that all calculations are carried out by the on-board computer, and the robot delivers the shells at its command. The new system has significantly increased the striking power and efficiency of domestic artillery. Partly also because, in terms of its functionality, this self-propelled artillery is approximate to MLRS – multiple launch rocket systems. At the same time, artillery shells are ten times cheaper than rockets.
The target for “Koalitsiya-SV” can be command posts, air defence and missile defence systems, field airfields, supply lines and rock roads in the deep rear of the enemy. “Koalitsiya-SV” is also focused on the destruction of tactical nuclear warheads delivery vehicles. Simply put – for counter-battery fighting. No less rapid is the self-propelled artillery’s reaction to air targets.
The base of the self-propelled artillery is the platform of the T-90 tank. The modern long-barrelled 2A88 152 mm gun is cooled with an alcohol solution, which avoids overheating during intensive shooting. Here the experience of cooling the radar sight on a fighter jet came in handy. A chrome-plated barrel and active-jet ammunition allowed to increase the firing range of “Koalitsiya” to 70-80 km. For comparison: the 2S3 “Akatsiya” self-propelled artillery has a range of up to 20 km, the more advanced “Msta-SM” hits targets at a distance of up to 30 km.
To increase the rate of fire, the developers planned to release a double-barrelled “Koalitsiya-SV”. The “politological” name of the self-propelled artillery is actually connected with this idea: two barrels are already a coalition, that is, an alliance. But as a result, they stopped at the classics, increasing the degree of automation.
As a result, the crew is located not in the combat compartment (in the turret), but in the body of the vehicle, since the firing control is remote, and the loading, as was already mentioned, is automatic. Hence the high rate of firing – up to 16 rounds per minute. In terms of the degree of automation of “Koalitsiya”, both the American Paladin M109A7 and the German PzH 2000 are inferior.
A “pleasant” feature of “Koalitsiya” is the ability to work in the “Barrage of Fire” firing mode – this is when the target is covered simultaneously by several shells fired from one gun, and each shell follows an individual trajectory at different angles. The range of self-propelled artillery ammunition includes guided projectiles from the “fire and forget” series.
“Koalitsiya” is integrated into the tactical level automated control system: the self-propelled artillery receives target designation from scouts on the ground and from aircraft, including drones. In the future, it is possible to install the “Koalitsiya-SV” on wheels – to radically strengthen motorised rifle brigades. It is not in vain that this self-propelled gun, which is considered one of the most powerful and dangerous in the world, is called the “Russian sledgehammer”.
