Meanwhile, this is a story with a continuation, and, I would say, It turned out to be very successful sequel. And it all began is not rosy.

It all started in the distant 1968 year as a continuation of the idea of ​​self-propelled guns. job has been issued to develop anti-gun with ammunition ballistics and 125mm tank gun smoothbore D-81 (2A46).

Work on the assignment start time as already mentioned DB-9 F. F. Petrova. Chief designer of the project was in. A. Golubev.

At the same time we designed two options: towed gun D-13 and SD-13 self-propelled.

2A45 SD-13 ("Octopus-A") turned, but in a series of gun and went 2A45M "Octopus-B".

Gun "Sprut-B" is obtained by applying a tank gun D-81 on the carriage towed 122-gaubitsы mm D-30 plus units for movement.

Gun barrel has a length of approximately 51 caliber and consists of a tube with a muzzle brake, bonded to the casing of the chamber, and breech. The trunk does not cut, which provided the higher pressure of propellant gases in the barrel and the projectile message very high initial speed, increases its armor. for example, Subcaliber piercing projectile "Octopus-B" has an initial rate 1700 m / s compared with 1040 m / s in a 85-mm anti-rifled cannon D-48.

recoil device (hydraulic brake rollback and pneumatic recuperator) placed above the barrel in a box cot.

The gun is provided with a shutter with a vertically disposed and the mechanical wedge (kopirnoy) semi-automatic. The safety mechanism, located at the bottom of the shutter, It does not allow a shot when not fully closed. Before the first shot shutter manually opens, and further due to the recoil energy - automatically. In this case, the hammer is cocked and ejected cartridge cases. In order to prevent flashback after the shot has a special mechanism for purging the barrel.

Jack provides rise to the height of the mast, necessary for the information and breeding the trails, and for lowering it to the ground. Hydraulic lift is carried out on cannon maximum clearance, as well as raising and lowering the wheels. Hydraulic can operate from a hand pump, however, the main energy source for it is the auxiliary power unit, placed on top of the machine frame before the shield cover (Right from the trunk).

The auxiliary installation is based on engine MeMZ-967A is used as a translation for mechanization processes gun out of service to the stowed position and back, and to provide a self-motion gun on the battlefield.

Mechanisms of control and the driver's seat located at the top of the machine frame on the left of the barrel. When using the auxiliary power unit maximum speed guns of dry dirt roads reaches 10 km / h. Fuel distance is 50 km.

the, that the output was very successful gun "Sprut-B", understood all. She is, more precisely, its characteristics, relevant today, despite the relatively long lifetime. On the other hand, What more could you want, if still pierces the armor of "potential" tanks?

clear, that should be the next step. And it was made, when everyone around the same gun was built armored skeleton, gave a more powerful engine and tracked chassis.
