Already at the end of World War II, the operating altitudes of the bombers exceeded 10,000 meters, the speed rose to 500 km / h, and the navigation equipment and bomber sights made it possible to carry out targeted bombing in any weather. In this regard, in 1947 in the design bureau of plant number 8 named. Kalinin under the guidance of designer L.V. Lyuliev, a new
100-mm anti-aircraft gun, designated “KS-19”. In the autumn of the same year, an experimental series of four KS-19 guns was manufactured at plant number 8 and sent to factory and field tests. The 100-mm anti-aircraft gun KS-19 of the 1947 model of the year was adopted by the Decree of the Council of Ministers of the USSR in March 1948. This weapon was intended to destroy high-flying air targets with a speed of up to 1200 km / h and an altitude of up to 15 km. Its device also made it possible to fire, if necessary, and at ground targets.Shooting at air targets could be conducted according to the data generated by PUAZO, as well as with the help of sighting devices. The main type of shooting is according to the data of the radar complex in automatic mode. Already in 1950, plant No. 8 modernized its 1947 model 100-mm anti-aircraft gun in order to improve its combat and experimental characteristics.
The new modification of the gun, designated “KS-19M2”, had a maximum horizontal firing range of 21 km; the maximum vertical firing range with the fuse set to the time is 12.7 km; the maximum vertical firing range with a proximity fuse was 15 km and the effective vertical firing range was 13.7 km, which made it possible to fight almost on an equal footing with all strategic bombers of that time among our potential adversaries.
The modernized KS-19M2 cannon is a mechanized cannon, in which the installation of the fuse, the ramming of the shot, the closing of the bolt, the firing of the shot, the opening of the bolt and the extraction of the spent cartridge case after the shot is carried out by appropriate mechanisms. The gun consisted of: a barrel with a vertical wedge semiautomatic bolt and semiautomatic; cradles; tray; hydropneumatic rammer, with hydraulic accelerator; automatic fuse installer; recoil devices; guidance mechanisms; balancing mechanism; sighting devices;machine tool, shield cover, platform KZU-16 and a set of hydraulic servo drives GSP-100M. A number of changes were made to the new gun, including the introduction of a monoblock barrel with reinforced rifling fields. An efficient multi-slot muzzle brake was mounted on the barrel. The lifting and slewing mechanisms worked from a hydraulic drive and manually. Spring balancing mechanism. The swinging part of the gun was mounted on a four-axle platform KZU-16 with torsion suspension. Trolleybus wheels – with GK bus.
The gun had four modes of firing: 13 shots (in 1 minute); 45 shots (in 5 minutes); 110 shots (in 60 minutes); 160 shots (120 minutes).
For firing from the 100-mm anti-aircraft gun KS-19 at air targets, unitary shots with a fragmentation grenade were used (only with steel shots specially designed for the KS-19), and for firing at ground targets, shots from a 100-mm field gun were used BS-3 with high-explosive fragmentation, armor-piercing tracer and cumulative shells (moreover, only with brass sleeves).
The gun was transported by an AT-S artillery tractor. The KS-19 battery included 8 KS-19 guns, a SPO-30 power station, a GSP-100M hydraulic power drive system, a SON-4 gun aiming radar, and a PUAZO-7 anti-aircraft artillery fire control device. The SON-4 radar station could detect air targets at a distance of up to 60 km, which made it possible to fire in poor visibility conditions and at night. The coordinates of the target, determined by the gun aiming station, were transmitted to PUAZO-7.The aiming of the gun at the anticipatory point was carried out by the GSP-100M hydraulic power drive from the PUAZO-7, but there was also the possibility of manual aiming. The hydraulic power drive system made it possible to automatically remotely control guidance in azimuth and elevation of up to eight guns, as well as to automatically set the response time of the anti-aircraft projectile fuse according to PUAZO data.
The 100-mm anti-aircraft guns KS-19 were in service with the Soviet army for more than 20 years, and the last of them were removed from combat duty only in the 1970s. From 1948 to 1955, plant No. 235 (Votkinsk) manufactured 10151 100-mm KS-19 anti-aircraft gun of all modifications.
