SU-152P (Obiekt 116)

In the course of work on the SU-100P, there was developed yet another self-propelled installation “Object 116” (SU-152P). It differed from the SU-100P main armament, elongated body and chassis. The layout of the vehicle remained the same. The 152-mm M-53 gun of the design bureau of Perm plant No. 172 was mounted on the pedestal in the fighting compartment. The gun was equipped with a slotted muzzle brake and a spring balancing mechanism. The sectorial mechanism of horizontal guidance had an electric drive. The lifting mechanism is manual. The ammunition consisted of 30 round-shell loading rounds. Combat rate of fire due to the use of a spring rammer was four to five rounds per minute. The crew of the self-propelled guns - five people.

Self-propelled artillery mount “Object 116” (SU-152P) was intended for arming artillery units of tank and mechanized formations. It was developed in Sverdlovsk at Uralmashzavod by the design bureau OKB-3 under the leadership of the chief designer L.I. Gorlinky in 1948-1949 The design and development work on the creation of the Object 116 self-propelled gun (SU-152P) was carried out simultaneously with the development of the SU-100P self-propelled guns. A prototype machine was manufactured in the I quarter of 1949. In March-April of the same year, its factory tests were conducted in the amount of 2904 km of run and 40 shots. During the tests, a significant number of deficiencies were identified in the design of the base chassis and artillery system.

The prototype self-propelled guns "Object 116" (SU-152P) differed from the SU-100P in the main armament, elongated hull and undercarriage. The power plant, transmission and chassis units were the same as the SU-100P, but the caterpillar mover consisted of seven road wheels and four support rollers. The combat weight of the car is 28.7 tons. A prototype of the machine was made in early 1949. During the tests, a large number of shortcomings were revealed both in the design of the chassis and in the artillery system. In order to save money, further work on improving the chassis was carried out as part of the development work on the SU-100P on the basis of the Decree of the Council of Ministers of the USSR of October 15, 1949.

The crew of the self-propelled guns consisted of five people. The semi-closed type self-propelled gun was developed according to the layout scheme with the aft arrangement of the fighting compartment. In the front of the case was the transmission compartment. Behind it, on the right was the power plant compartment, and on the left was the control compartment, in which the driver’s workstation was equipped. In the roof above the control compartment there was an access hatch, which was closed with an armor cover. To observe the terrain, two prismatic viewing devices were installed in front of the driver’s hatch.

In the fighting compartment on the pedestal, a 152.4 mm M-53 cannon was designed by the design bureau of Perm factory No. 172 (Motovilikha). The gun had a horizontal wedge semi-automatic shutter and was equipped with a slotted muzzle brake. The recoil brake is hydraulic, the knurl is pneumatic. The limit value of the rollback was 1100 mm. The balancing of the gun was carried out using a spring mechanism, the vertical columns of which were located behind the armored shield of the gun. Aiming at the target was carried out with telescopic or periscopic sights. The angles of vertical guidance ranged from -5 to + 30 °, horizontally - in the sector of 143 °. The sectorial mechanism of horizontal aiming of the gun had an electric motor drive. The sector-type lifting mechanism had only a manual drive. The ammunition for the gun consisted of 30 rounds of separate shell loading.

Armor protection of self-propelled guns "Object 116" (SU-152P) - bulletproof. The body of the self-propelled gun was welded from armor plates 10, 15 and 18 mm thick. The armor shield of the gun had a box-shaped shape, the armored rolled sheets of which were 8 and 20 mm thick and connected with rivets. The power plant, transmission and chassis units were the same as the SU-100P self-propelled unit, except for the suspension and caterpillar propulsion, in which the number of support rollers was increased from six to eight, and the number of track rollers from 12 to 14. changes were introduced to the suspension system of the machine. The combat weight of the car is 28.7 tons. Cruising range but the highway was 300 km.

In addition to self-propelled guns based on the chassis of the “Object 105”, at various times a large number of experimental and serial combat vehicles were developed. Among them were armored vehicles of the 2K11 Krug anti-aircraft missile system, GMZ crawler mines, the ZSU-37-2 Yenisei self-propelled anti-aircraft gun, the Object 112 armored personnel carrier, the Object 117 self-propelled searchlight and others. Finally, in the late 1960s, this chassis formed the basis for the 2SZ Akatsiya self-propelled howitzer.

The self-propelled artillery unit SU-152P was developed in Sverdlovsk on the basis of the SU-100P units and had the designation "Object 116". The self-propelled gun was intended both for delivering attacks from a closed position and for fighting enemy tanks, the very powerful 152.4 mm M-53 gun had a horizontal angle of 143 °, which provided ample fire maneuverability for the anti-tank fight, and the transportable ammunition tank was 30 the shots made it possible to shoot well .. But, not everything was so rosy - despite the lengthening of the undercarriage by one skating rink, the self-propelled gun weighing 28.7 tons was too easy for the return of such a powerful gun.

Therefore, it was necessary to install a rather exotic looking slotted muzzle brake, which helped to reduce recoil to a reasonable value, but operators could forget about the invisibility of firing with small elevation angles. Powder gases from this design would unmask the gun even on asphalt.

SU-152P was not accepted into service. At that time, there was no need for self-propelled guns of this type working from a closed position, but with t.z. VET machine had a bunch of fatal flaws. But, it should be noted that the UZTM designers did not calm down for this.

The project "Object 116" / SU-152P was to lead to the emergence of a promising self-propelled artillery installation with sufficiently powerful weapons, capable of combating targets both at the forefront and from closed positions. Nevertheless, the presence of a mass of original ideas and solutions led to certain difficulties, which is why the development of the entire family of projects was noticeably delayed. Subsequently, the leadership and command changed their views on the modernization of the ground forces, as a result of which the project was closed. The topic of self-propelled guns with guns of 152 mm caliber returned only in the mid-sixties, but later combat vehicles were based on other ideas and therefore had minimal resemblance to the experimental SU-152P.
