The gun is mainly used for attacking maritime targets and air defense, as well as anti-missile and carrying out bombing missions on the other side. The turret adopts stealth design. The muzzle velocity of the shell is 870 m/s, the barrel length is 5500 mm, and the firing rate is 10~90 rounds/min. For maritime targets, the maximum range is17500m and the effective range is12000m; for air targets, the maximum range is 8000m and the effective range is 6000m; The gun weighs 17000 kg and has the advantages of compact structure, light weight, high firing rate and short reaction time. At a distance of 20000 meters, the probability of a single shot hitting the target can reach 0.7 ~ 0.8.
On the 168 ship, we didn't see the double 37 rapid-fire guns common on new domestic ships. Instead, we found the 7-tube 30 mm short-range defense system "Vulcan" rapid-fire gun newly developed by China. From the appearance, the design of the gun draws lessons from the Dutch "goalkeeper" defense system to some extent.
This system was developed in the early 1990s. In order to reduce the cost and simplify the logistics, the ready-made barrels of Russian AK-630 anti-aircraft guns imported from China were adopted, but the number increased to seven, and the speed reached an astonishing 5,800 rounds per minute. Its response speed is fast, its reliability is good, its hit accuracy is high, its power is great, and its overall performance exceeds the "dense array" commonly used by navies of various countries at present.
The servo system adopts advanced algorithm, the power amplification adopts digital pulse width modulation system, and the closed-loop circuit ignition control technology is applied for the first time, which can eliminate the impact deviation and promote the AC system.
Unlike the "goalkeeper", the gun has no search radar and lacks the ability to track and scan multiple targets. Its 1/K band Doppler tracking radar can automatically switch to eliminate the mirror image reaction, while the reverse time of ODF-730 spot tracker should be less than 3 seconds, and the measurement accuracy is 0.3 meters.
