Chase/naval gun
At the back of the 12 tube anti-torpedo deep-water bomb launcher, a single tube 100 mm compact naval gun developed by French company Creusot Loire is installed, which 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 shell adopts stealth design, with an initial velocity of 870 m/s, a barrel length of 5500 mm and a firing rate of 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. The probability of a single shot hitting a target at a distance of 2000 meters can reach 0.7-0.8.
This gun is probably made in China after the French patent was introduced. As early as the mid-1980s, China purchased two sets of this device from France, of which 1 set was installed on the anti-submarine reinforced "Jianghu" class frigate 544. According to the application effect, China Navy was very satisfied with the performance of the gun, and then signed an import production line with France, which provided technical support to further improve the gun to equip newly designed large surface ships.
Haikou is mainly used to patrol the South China Sea of China. In the face of the weak navy of Southeast Asian countries, it can still complete the combat mission well with the advantages of fast firing speed, fast response speed, high hit accuracy and great power. After all, sometimes shells are more useful than missiles. The main rival of Haikou Ocean Escort in the Gulf of Aden is pirates armed with light weapons, so it is unlikely to use missiles.
air defence missile
As a first-class air defense destroyer, Haikou Ship is equipped with China's first ship-borne long-range air defense missile, model HHQ-9, developed from land-based HQ-9A. The missile has no wings, the minimum operational altitude is 20m, the maximum operational altitude is 30km, the minimum operational distance is 6km, the maximum operational distance is120km, and the maximum flight speed is greater than Mach 4.2. The missile has a total length of 6.8m, a diameter of 0.47m, a missile weight of1300kg and a warhead weight of over180kg.
The missile launch mode is vertical cold launch, with 8 sets (the first 6 sets, the second 2 sets, each with 6 bombs), with a total of 48 HHQ-9A missiles. The launcher is similar to the revolver used by the Russian navy, but the launching system of SA-N-6 uses one launcher for eight missiles, while China's Haihong -9 uses a separate launcher for each missile. In contrast, Haihong -9 has a more reliable launch mode, faster launch speed and higher safety rate.
Anti-ship missile
Because the design idea of Haikou is air defense first, supplemented by anti-ship, its anti-ship combat capability is not as good as that of China Navy's new improved destroyer (usually equipped with 16 anti-ship missile), but it is also equipped with eight C-803/ Eagle Strike12 supersonic anti-ship missile launchers. The missile launcher is also designed to be cylindrical, which is more conducive to the stability, accuracy and guarantee of launch.
The C-803 missile continues the aerodynamic layout of the C-802, and its length seems to be longer than 6.4 meters of the C-802, with a maximum range of about 250 kilometers. It retains the small turbojet engine structure of C-802, and the warhead fairing is slightly thinner than the former. It uses a new solid rocket engine with a terminal speed of Mach 2.3, and can do difficult "snake avoidance" maneuvers. In addition, there is an antenna in front of the folding wing to receive the data link, which can be guided by ships, helicopters and even satellites for over-the-horizon attacks.
C-803 can be said to be a masterpiece of modern anti-ship missiles, and its excellent performance will surely play a formidable role in future maritime wars/conflicts. The short-range defense system on Haikou is seven 30 mm Vulcan rapid-fire guns newly developed by China, one under the bridge and the other on the upper right of the hangar.
From the appearance, the design of the gun draws lessons from the Dutch "goalkeeper" defense system to a certain extent, which was developed in the early 1990s. In order to reduce the cost and simplify the logistics, the ready-made gun barrel on Russian AK-630 was adopted, just like the double 37 system, but the number was increased to seven and the speed reached 5800 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 short-range defense systems such as "dense array" and "goalkeeper" commonly used by navies of various countries.
The servo system adopts operational amplifier, and the power amplification adopts digital pulse width modulation system. The closed-loop firing control technology is applied for the first time, which can correct 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. The tandem arrangement also enables the two guns to cooperate in an emergency and improve the damage probability. Haikou's anti-submarine capability is very complete, mainly equipped with 1 Block 3 combined improved "Whitehead" anti-submarine torpedo system and 1 Ka -28 anti-submarine helicopter.
"Whitehead" torpedo is a light anti-submarine torpedo designed by China in 1980s, which imitates Italian A-244S torpedo. The mine is 2.75 meters long, 324 mm in diameter, with a range of 15 km, a speed of 35 knots and a maximum dive depth of 500 meters. It is powered by lead-acid batteries. Torpedoes can be carried by surface ships or mounted by anti-submarine helicopters.
In anti-submarine sonar, there are spherical nose sonar and towed sonar. The arrangement of sonar is special, which changes the traditional front-tail dragging mode and turns to the side-tail arrangement. When the sonar works, the winch rises from the left/right tail. Disadvantages are that sonar arrangement/recovery is difficult, its accuracy is poor, and its work is greatly affected by sea conditions. The deployment of this sonar in Haikou seems a bit intriguing. Automated command system;
The network of shipborne C3I system includes the local area network inside the shipborne command center and the interconnection between the command centers. * * * Network topology in the form of shared media and bus is widely used, and the speed of bus usage has also developed from low-speed 1Mbps to medium-low speed standard 10Mbps bandwidth.
Ipn- 10 is widely used in China Navy's new large and medium-sized surface ships. The system adopts MHIDAS multi-channel advanced integrated distribution structure system. The bus system adopts modular structure and is divided into main line and branch line. The main line can reach 50 meters, and the longest distance between two terminal devices can reach 400 meters. The data transmission rate of the bus can reach 10Mbps/ s, and the maximum number of users can reach 256, which can meet the requirements of medium and large ships for transmission distance, transmission rate and number of terminals.
Haikou Ship is also equipped with a new generation of ZKJ-5 operational intelligence command system developed by the 709th Research Institute of China Shipbuilding Industry Corporation, which is the third generation operational intelligence system in China. Compared with the second generation, the overall performance has been greatly improved. The system is accelerated to 100M fast Ethernet (switched), which has greatly improved the real-time performance, network capacity, network analysis and modeling, reliability and so on.
It is reported that Haikou has also adopted the first set of naval formation campaign and tactical automatic command system (H/ZBJ- 1). The new command system adopts more powerful and faster data bus, more advanced flagship data display hub, Ethernet LAN based on optical fiber data bus and open system interconnection structure. This system combines the comprehensive communication, navigation and identification between the forces in the battle group, and is used to exchange joint tactical data links, thus effectively commanding, managing and coordinating the fleet ships and shore-based and space-based detection platforms. The electronic equipment on the Haikou is mainly a set of "slab-brick" phased array radar system developed by China, and its layout is similar to that of American and Japanese Alibek class destroyers and King Kong class destroyers. It is the fifth country to master this technology after the United States, Russia, the Netherlands and Japan.
The system consists of four radar emitting surfaces installed in four directions of the bridge, which are quadrangular, and the radar search distance is within 450-500 kilometers. The working mode is active, and the shape is a box, which is fixed through the front, rear, left and right sides and fixed by grids. The belt is an active S-belt, and the angle formed by the front part and the side section of the hull is about 80 degrees, and the total weight is about 1.25- 1.3 tons.
