Russian 130-mm anti-aircraft gun KS-30 (1948)

History of Creation

In 1947, the design bureau of the plant number 8 under the control of head designer LV Lyuleva developed those. project on "31410." The project has received the title of "130-mm gun with a mobile CSP." The gun was designed to destroy air targets, hovering at an altitude of 19,500 m According to the project, she had to hold the subsequent features: projectile mass — 33.4 kg, the initial velocity — 970 m / s; ceiling — 20 thousand meters in the same the project was approved and the Ministry of GAC weapons. Gun, given the index of the COP-30. Later in 1948 the plant experienced number 8 made reference tools COP-30 of the movable type that was small factory tests in November of the same year. December 25, 1948 the standard was delivered to the customer, December 28 he was expelled for Research antiaircraft artillery range (NIZAP). 1948 by the Kirov was done by an experienced platform CS-30P. During the 1949 revision was carried out an experienced reference platform and drawings. In December 1949, it was done and delivered to the customer has four platforms.

5 — April 17, 1950 the most experienced battery KS-30 (four guns to the GSP-130) was held at the plant number 8 factory tests without firing. But the military refused to accept their acceptance, as some mechanisms they have not been made. In addition, problems were noted: for example, the number 3 on the system tray swung correctly, there were failures rammer, etc.

The second delivery of the battery was scheduled for June 1950 By this time, the change had to do 2-ALD-100-2 (power supply units) delivery Minelektroproma. They are engaged in the creation of plant number 686. Plant Number 172 has been appointed as the head producer of the COP-30. The plant number 232 engaged in the creation of swinging for anti-aircraft guns.

Modifications

The plant number 232 in 1953, started the ready experienced trunks. In the new trunks threaded portion has been changed (the number of grooves has been reduced from 40 to 28, with all the width of the field changed from 4.2 mm to 6.29 mm, width of rifling — from 6.0 mm to 8.3 mm). It is possible to increase the reliability and stability of the projectile, and reduce wear on the barrel.

The plant number 172 April 20, 1956 sent to the Main Artillery Administration letter, in which sought to make better properties 130 mm anti-aircraft gun KS-30. And it offers:
— to increment the initial velocity of the projectile from 970 to 1100 m / s;
— increase speed drives pointing: horizontal — from 25 to 40 deg / sec; vertical — from 9 to 20 deg / sec;
— enter into the design of a mechanism for automatic adjustment for horizontal and vertical angles pointing guns with the tilt axis of the pins basket.

To obtain these properties, the plant proposed to introduce a muzzle brake and a loading mechanism, power increment GSP, enter partial leynirovanie trunk or use a composite pipe.

In addition, it was proposed to use the Unified CM-52 with mechanization supply of ammunition from the cellar. The main objectives of the modernization was to reduce the time peresnaryazheniya guns and facilitating the work of calculation.

The device gun

The barrel anti-aircraft gun consists of a tube, breech and couplings. Pipe has 28 grooves (in the pipes of early production — 40 grooves). All pipes slope rifling immutable. Horizontal wedge bolt is semi-automatic follower (mechanical) type. After the closing of the loading gate is done by an automatic closing mechanism. Impact shutter mechanism is in place through the automatic time switches (mechanical) in the trigger mechanism. Mechanical timer with a tray so interlocked makarom that the shot is done only after vorachivaetsya tray in the up position. In the breech assembled ejection mechanism.

Cradle — cast box with a pipe and a cast upper link, welded to it. On the tube front collar fastened with rollers on which the reel when rolling back and moves the barrel. Hydro-pneumatic rammer equip the hydraulic booster. The structure of anti-recoil devices include hydro-pneumatic brake rollback riveted type overrun brakes and two spring-hydraulic type. When fired, the recoil device motionless.

Welded machine having cast base, spinning on the ball two-row pursuit. Each series 112 has balls (diameter 40 mm).
Gorizontiruyuschee device intended for mounting and leveling the rotating part of the tool. Frame apparatus mounted on a ball bearing 4 and jacks that are mounted on the crosspiece. Frame gorizontiruyuschego device using jacks moves relative to the cross angle of 2 degrees in which at least a vertical plane. I hoist a single sector. Rotating pin device provides unlimited rotation in azimuth.

Guidance mechanisms are mechanical transmission of hydraulic actuators, which is carried out by means of automatic fire. Not counting avtonavodki, with drives GSP-130 can run automatic and manual leveling according to the control unit by means of anti-aircraft fire detection devices. Hydraulic control is carried out by means of an automatic tip-off devices Manual Focus, shift knobs for all that are installed in the "Semi-automatic". The composition of spring balancing mechanism comes two pull-type column.

Welded spider has folding legs arranged crosswise. In the stowed position, legs folded and attached to the cradle, and the spider machine. Crossings in the stowed position serves as a wagon. Sliding front and reverse stowed attached to the cross, and on translation are rolled back into the firing position.

Moves — single axle with torsion cushioning carts. For the rear and front wheel moves used by YAZ-200 with tires GK (12.00 x 20 inches). For lowering and lifting tools in the translation from the fighting in the stowed position and back are jacks. The gun carried by an artillery tractor languid.

The complex includes:
— 8 or less guns;
— gun power station ESD-50 BCA, placed on two-axle trailer;
— anti-aircraft fire control device;
— GSP-130 system, which serves to enter into executive aggregates data and does not give effect to 8 guns;
— SLEEP-30;
— cable network connecting all elements of the complex, with all this central control box (TSRYA) connects with poise, and each instrument line length of 300 meters, consisting of 4 sections, 75 m cable.

Creation

Creating the factory number 172 was scheduled to begin in the IV quarter of 1951, the plan had to pass eight guns, but not a single plant has not handed over. In 1952 it was planned to produce 16 guns, but none of the 1st are not made. Almost creation guns COP-30 began in 1954 — 24 units. (Planned for 32 guns), 1955 — 120 units. (120) 1956 — 255ed. (250) 1957 year — 333 plus one for the polygon (328). Total, including seasoned, made 738 guns. Create ended in December 1957.
