Paired universal 76-mm gun mounts AK-726 was armed with many ships of the Soviet Navy, including being in battle formation escorts project 1135 patrol and export project 1159. Work on the creation of artillery systems were launched in CDB-7 in April 1954 g. Factory tests were carried out in 1958 g. and given the generally positive results, but field testing and debugging the installation was delayed until 1963 g. The Navy of the USSR it was adopted in 1964 city, Serial production was carried out with 1961 by 1988 gg.
AK-726 artillery system designed as deck-tower, with a fairly long-term management of automatic fire and in combination with fire control radar. It consists of a combat turret and offices. The crew compartment is a turntable (machine), which are mounted on swivel gun mount portion, mechanisms for vertical and horizontal aiming, elevator feeding cartridges, Cooling System trunks and sights. On a turntable and mounted armor protection, made of thick steel sheets 5 mm. It protects calculation, instruments and mechanisms of small caliber shell fragments.
Aligning part owl gun mount is a system of two 76-mm automata, a cradle disposed in the common. The cradle mechanism associated with the vertical guidance toothed sector. vertical guidance mechanism is provided with electric drive and provides a speed vertical guidance 30 city. / c.
Each machine installation AK-726 is composed of a shutter stem, loading rod spring with a gear-type accelerator, a receiver with a vertical and transverse feeds, hydraulic brake spindle type needle brake rollback and roll forward compensator. The barrel is configured as a monoblock, its length is 59 calibres, on the muzzle of the ejector set, providing purge the barrel after each shot (during the shooting of the tower is part of the calculation of artillery systems, and ingress of propellant gases from the bore in the tower is undesirable). Cooling trunks made seawater in between bursts; barrel life is about 3000 shots; survivability of the machine - 5000 shots.
ammunition supply to the machine is made from receivers turret compartment elevators supply for each machine separately. Elevators have independent drives - hydraulic and manual. Submission of ammunition in the turret compartment in the gun mount racks made by hand from the ship's elevators or ship racks through a window in the fixed drum of the ship at the time of cooling the barrel or other breaks in shooting.
All the way to feed the cartridges are transported in cages for 2 each cartridge. Performance elevator provides practical rate, equal to the rate of automatic fire.
For firing the AK-726 uses shots unitary loading (ammunition) UZSB-62RP (antiaircraft) and UOFB-62 (high-explosive). Shells AP-BZ-shots UZSB 62RP equipped with radar fuze LR-51L. High-explosive shells RP-62 shots-62 UOFB have an impact fuse HS-67 self-killer, having a response time 28-31 give me a sec. shooting at the ceiling is self-killer 11 000 m. firing can be controlled remotely by "Foot-6" A remote control system 67 from the firing control device of the ship or MR-105. Also provided with the fire control post, located in the tower. Data on installed in office equipment and guidance PUGN PUBN can come from the central station (central leveling) or "Prism" sight (autonomous route guidance).
