BS-100 3 mm field gun
On April 15, 1943, the Resolution of the State Defense Committee on strengthening anti-tank defense was signed. It was necessary to create an anti-tank gun that would be able to penetrate the armor of Ferdinand, Tiger, and other promising tanks Germany. There was no time to create a gun with a new ballistics, so I had to choose between the ballistics of a 100-mm gun B-34, a 107-mm gun M-60, and a 122-mm gun A-19. According to Grabin, the optimal in this case is a 100-millimeter naval gun B-34 having a deep cut (1,5 millimeters). The TsAKB in the shortest possible time developed documentation for the field cannon, which received the S-3 index. The documentation was sent to factory No. 172 on June 04, 1943. In 1944, the gun was adopted. The chief designer is Grabin. In 1944-1951, 3816 units were manufactured. Production was carried out at factories No. 232 "Bolshevik" and No. 7 "Arsenal".
The structure of the barrel of the gun includes: monoblock pipe, breech, rear and front clips, clutch and muzzle brake. The two-chamber muzzle brake has an efficiency of around 60 percent. Vertical wedge gate with semiautomatic copying (mechanical) type. The gun is equipped with a hydraulic recoil brake and hydropneumatic knurler. The recoil cylinders roll back with a barrel during a shot. The cradle is trough-shaped riveted. In the cradle installed recoil device. Swivel screw mechanism. The lifting mechanism is two-sector. The balancing mechanism of the pushing type, hydropneumatic, consists of a pair of parallel operating cylinders.
Suspension torsion. It turned on / off automatically during the information / dilution of the bed. The wheels from the GAZ-AA truck had a reinforced rubber tire and a special wheel hub. The gun was transported without a front end. For its transportation used tractors I-12 and AT-L, an armored personnel carrier M-2 and a ZIS-151 vehicle.
Sights: panorama C-71-5 and optical sight OP1-5 for direct fire. In the guns of the first editions of the direct-sight sight was absent.

Direct shot range - 1040 / 1070 m;
The maximum firing range - 4 th. M.
Armor-piercing piercing projectiles 3BM25 and 3BM8:
Shot –3UBM11 and 3UBM6.
Projectile weight - 5,7 kg.
Cumulative armor-piercing shells 3БК17, 3БК5:
Shot - 3UBK9 and 3UBK4.
High-explosive fragmentation shell OF-32 (1980-s):
Shot - 3UOF10 / 3UOFXNNXX;
Projectile weight - 15,6 kg;
Explosive mass - 1,7kg;
Direct shot firing range - 1100 m;
The maximum firing range - 20600 m.
Controlled anti-tank missile 9М117 complex "Bastion":
Shot - 3UBK10-1;
Firing range - 100-4000 meters;
Penetration - under 60 degrees - 275 mm, at an angle 90 degrees - 550 mm.
It is intended to destroy openly located and sheltered (in trenches, trenches) manpower, including body armor, and openly located unarmoured vehicles.
In the post-war years, the BS-3 cannon was subjected to a small modernization, which primarily concerned ammunition and sights. Prior to the beginning of the 1960's. BS-3 guns successfully penetrated the armor of any Western-made tank. However, later the situation changed: the BS-3 sub-caliber armor-piercing shells were unable to penetrate the frontal armor of the turret, as well as the upper frontal armor of the Chiften, M-48А2 and M-60 tanks. Therefore, urgently developed cumulative and sub-caliber shells were developed and adopted. Moreover, the sabot shells were able to penetrate any armor of the M-48А2 tank, as well as the towers of the Chiften and M-60 tanks, but did not penetrate the upper frontal armor of these tanks. Cumulative shells were able to penetrate any armor of all three armored vehicles.
In the 1980's, the BS-100 3-millimeter cannon entered the 9М117 anti-tank projectile (the Bastion missile system), the effective firing range of which left 100 to 4000 meters and pierced 550-millimeter meters. However, their troops received little.
