Single 130 mm gun developed by the Institute of Mechanical and Electrical Engineering of Zhengzhou (Zhengzhou 713 Institute), and produced by Inner Mongolia 2nd machinery factory (Baotou). The original design uses a single tube dual link ammunition handling and water-cooled systems; Barrel length (with breech) of 70 times of caliber; using grenades, the high explosive shells, gun-launched missiles; fully automatic replenishment gear; rate of fire 40 rounds / minute; range (non-guided shells) 29.5 km; whole gun weight (excluding peripherals) greater than 50 tonnes; fiberglass stealth anti-shield.
The design of this gun is estimated to learn some proven technologies of the Russian AK-130 130 mm twin-barrel gun, mainly on the mechanical design, which is a weak place in Chinese ship-borne guns. And the gun electrical control and aiming servo system are all dependent on the all-new localization design.
Increase of installation fitness, basing on the basis design, the gun weight is decreased and applied with anti-recoil design. Weight loss design as far as possible to ensure the requirements of the structural strength to use aluminum alloy components, which is weight loss designed a common practice in ship-based guns, such as the Russian AK-176 guns.
The anti-recoil design is the recoil energy decreases guns firing, in order to reduce the impact and vibration of shipboard equipment. As the single 130 mm gun’s indicators like muzzle velocity have been cured, and measures to reduce the recoil estimated device for retrofitting muzzle brake
