Back in action. M-46 guns in Special Operations
M-46 gun of the Russian army in position
As part of the current Special Operation, Russian artillery units use all types of available weapons. In addition, M-46 guns, previously withdrawn to the reserve, have recently begun to be returned to service. Despite their age, such guns have fairly high tactical and technical characteristics and are capable of effectively complementing modern weapons.
Return to service
In the spring of this year, the first reports appeared that the M-46 guns would again be used in the army. At first, unofficial sources wrote about this, and then the information was confirmed in materials from the Ministry of Defense. Also, to date, the department has published several reports on the work of M-46 crews.
As we now know, in the recent past the Ministry of Defense decided to replenish the active fleet of artillery weapons with old guns. M-46 products are removed from storage, undergo restoration and repair, and then are sent to the army. The volume and pace of such work are still unknown.
According to unofficial reports, the M-46 guns use foreign-made ammunition. Photos of shells and cartridges with markings in foreign languages were published online. This fact is associated with the peculiarities of the army supply system.
According to known data, M-46 guns have already been supplied to a number of units of the ground forces. Some of these guns with crews work as part of the “North” group of troops—they were the ones shown by the Ministry of Defense in its reports. Obviously, these guns are also available in other directions.
130 mm shot casings
Towed M-46 guns are used as long-range fire weapons and complement the existing howitzer artillery. With their help, troops attack and hit a wide range of fixed targets, such as enemy locations, command posts, concentrations of manpower and equipment, etc.
M-46 guns are actively used in counter-battery warfare. In terms of firing range, they surpass some of the enemy’s artillery systems. Thanks to this, our guns control large areas and defeat enemy targets that appear there.
Like other guns, the M-46 works in conjunction with modern reconnaissance and target designation systems. Data about the enemy comes from reconnaissance UAVs, counter-battery radars and other sources.
The M-46 and other towed guns operate exclusively from camouflaged firing positions. Such artillery is usually placed on the edge of forest plantations under the cover of trees and is equipped with additional camouflage. Active means of countering enemy reconnaissance, such as anti-drone systems, are also used.
If the enemy managed to identify the position and open fire, the crew is ready at any moment to move the gun to the stowed position and leave the position. This procedure only takes a few minutes.
During loading
In an interview with the Ministry of Defense, the crews of the M-46 guns speak well of their equipment and the results of its use. Despite their considerable age, such tools are quite capable of solving the entire range of assigned tasks. In some situations, the M-46 is as good as newer systems.
The enemy's guns
It should be noted that Ukrainian formations also have M-46 guns. However, in their case there is a very specific situation that imposes serious restrictions.
According to known data, before the start of the Russian Special Operation there were no M-46 guns in Ukraine. In August 2022, Croatia shipped 15 such guns and an unknown number of shells as military assistance. Subsequently, these systems repeatedly appeared in different sectors of the front.
15 guns from Croatia did not have a serious impact on the state of Ukrainian artillery. At the same time, they put an additional burden on logistics due to the need to introduce a new caliber. All this led to a clear result. The guns did not live up to expectations, and several units were destroyed by the Russian army.
In general, Ukraine cannot boast of positive experience in the use of M-46 guns. It is hampered by the small number of guns received, supply difficulties, the superiority of the Russian army and other factors. It is obvious that the remaining “Croatian” guns will also be destroyed in the foreseeable future and will not affect the course of the battles in any way.
Long story
The 130-mm M-46 cannon was developed in the second half of the forties by the design bureau of plant No. 172 (now Motovilikha Plants, Perm). It was intended for corps artillery of the ground forces and was supposed to replace the 122-mm A-19 mod. 1931/37
In 1951, Plant No. 172 began mass production of the new gun, and soon it officially entered service. Soviet industry produced M-46 products at least until the early seventies. During this time, several thousand guns were manufactured.
In the late fifties, the license and documentation for the M-46 were transferred to the friendly PRC. The gun entered service with the PLA under the designation "Type 59". Chinese enterprises built several thousand guns.
The main recipient of M-46 guns was the Soviet army. They were also exported to ATS and Third World countries. A number of foreign operators used their guns in combat.
At the time of its appearance, the M-46 was the longest-range domestic weapon that did not belong to the class of high and special power. This factor determined its service life. Guns of this type remained in units at least until the nineties. Then they were removed from service, mothballed and sent for storage.
Since that time, large stocks of 130-mm separate-case-loading rounds have remained available. They were no longer replenished, and ammunition with expired shelf life was disposed of. According to available data, in the tenth years the reserves were practically exhausted.
The moment before the shot
This is what now explains the appearance of foreign shells at the front. Iran and North Korea still maintain the production of 130-mm rounds and, apparently, helped the Russian army with their supplies.
Technical potential
M-46 arr. 1951 - a towed gun of a traditional appearance. During its development in the late forties, advanced ideas and solutions were used, which made it possible to obtain maximum tactical and technical characteristics.
The gun has a rifled barrel of 130 mm caliber and a length of 55 klb. The barrel is equipped with a muzzle brake with several rows of holes. A horizontal semi-automatic wedge valve is used. The barrel is mounted on hydraulic recoil devices.
The M-46 carriage has a traditional design with two sliding frames and a sprung wheel travel. The design of the carriage provides horizontal guidance within 25° to the right and left of the longitudinal axis. Vertical guidance – from -2,5° to +45°. There are sights for direct fire and from closed positions.
A wide range of 46-mm separate-loading rounds was developed for the M-130. It included shells of different types - several high-explosive fragmentation, armor-piercing, illuminating, etc. Guided ammunition was also created, but it did not reach series production. Foreign countries also have their own developments in the field of 130-mm shells.
Depending on the type of shot, the initial velocity of the projectile reaches 930 m/s. The maximum firing range of 33,4 kg high-explosive fragmentation ammunition is 27,5 km. Active-missile projectiles with a range of 35-37 km have been developed abroad.
The combat potential of the M-46 cannon is largely determined by its firing range. In this parameter, the 130 mm gun is superior to a number of modern systems of different calibers, up to 152/155 mm. The smaller mass of the projectile fades into the background.
Experience
The M-130 46 mm towed guns are used by both sides of the conflict and demonstrate some important principles and trends. For example, the guns of the Russian army showed that with proper organization of combat use, even old artillery can be effective.
At the same time, the great age of the guns leads to the need for their restoration and repair. It is also associated with problems with the supply of ammunition. The 130mm rounds had long been discontinued and their supplies were dwindling.
Ukrainian artillery does not show positive experience in using similar weapons. This is due to the small number of available M-46s, limited supplies of ammunition, etc. However, Ukraine’s failures are an exclusively positive factor that helps our army achieve its goals.
