The main gun of the 168 ship adopts the "China version" of French Creusot. Single tube 100 mm compact naval gun developed by Loire company. This gun was made in China after the French patent was introduced. As early as the mid-1980s, China purchased two sets of such devices from France, one of which was installed on the experimental anti-submarine frigate "Jianghu 4" class No.544 "Siping".
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 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.
missile
Anti-aircraft missile: The foremost weapon system on the ship 168 is two sets of deep-charge launchers, and a single-tube 100 mm main gun is equipped behind the deep-charge. The subsequent deck 02 was equipped with a Russian-made single-arm air defense missile launcher, that is, the "Skiley" medium-range ship-to-air missile system.
This system is a product of Russian navy in 1980s. It is an all-weather, multi-channel shipborne medium-range air defense missile weapon system, which can undertake air defense operations of ships and formations. The main targets of interception are bombers, fighter bombers, attack aircraft, helicopters and various anti-ship missiles. It is one of the most advanced medium-range ship-to-air missile systems.
The whole system consists of three-coordinate air search radar, continuous wave irradiator, TV platform, target distribution station, fine tracking display and control station, shooting console, central computer, missile, launcher, magazine and launch control equipment.
The weapon system has two launchers, which are single-arm oblique frames, located at the bow and stern of the ship respectively, and are used for loading and launching missiles. The azimuth rotation range of the launcher is 360 degrees, the altitude angle range is 0 ~ 70 degrees, and the rotation speed is 90 ~ 100 degrees/second. The launcher can quickly and automatically load the missile, and the time to load another bomb is 12 seconds.
The missile has a range of 40 kilometers and a flight speed of Mach 4. Using radio command correction and terminal radar semi-active homing guidance, it can intercept missile targets with a speed of 0.9M and a flying altitude of 10 m, as well as aircraft targets with an altitude of 3000 m and a distance of 40 km.
This kind of missile has several characteristics: it breaks through the traditional missile combat mode which needs special radar for searching, tracking and illuminating, directly uses MP-7 10 coordinates to search the target information of radar, cancels the tracking guidance radar, and forms a new missile combat mode of searching and illuminating. This simplifies the system structure and increases the number of fire channels to intercept the target. Therefore, the cost-effectiveness ratio of the system is high.
The missile adopts arc trajectory to intercept ultra-low altitude targets, which can effectively eliminate the influence of sea clutter and image multipath effect on missile guidance. Therefore, the system has the ability to intercept sea-skimming anti-ship missiles.
The system adopts modular structure and has flexible adaptability. The number of fire tracks can be determined according to the situation of the guided radar equipped on the ship, with a minimum of two and a maximum of 12, which can be equipped with all kinds of ships above 1500t.
That is, the system can receive the secondary target information given by the shipboard command and control system or fight independently, or it can fight independently. You can also accuse anti-aircraft guns of fighting and form an air defense system combining missiles and artillery.
There are only four 18 tube decoy launchers installed in the huge space behind the SA-N- 12 missile launcher, which shows that the China navy still has plans to install a vertical launch system for 168, and the model may be a new VLS system made in China. Recently, the Russian Navy has also launched a vertical launcher for Skilly missiles, which is in the form of six-pack, and its shape is quite similar to that of MK4 1 of the US military. Therefore, it is not ruled out that the 168 ship will adopt this launcher in the future.
Anti-ship missile: Between the chimney and hangar of 168 ship, four anti-ship and anti-submarine missile launchers are equipped, which makes the ship's anti-ship missile carrying capacity reach an astonishing 16!
Because of the latest improvement of Eagle Strike series, that is, the C803 anti-ship missile, the missile has the terminal supersonic flight capability and the range reaches an astonishing 250 kilometers. However, due to the influence of relay guidance capability, it is generally difficult to reach such a long range in actual combat.
Anti-submarine missile: The 168 ship may also be equipped with the launcher of the new "Chang Ying 1" anti-submarine missile and C803 anti-ship missile.
torpedo
168 ship is equipped with two sets of three-in-one improved "Whitehead" anti-submarine torpedo systems. "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.
depth charge
Two FQF-2500/ 12 anti-submarine/anti-torpedo depth bomb launchers are equipped at the bow of the 168 ship. The depth charge has a range of about 2,500m, which is mainly used for short-range anti-submarine. It is also the standard short-range anti-submarine equipment on China naval vessels.
helicopter
168 has a large hangar space and can carry 1 Ka -28 anti-submarine helicopter. This plane is the masterpiece of Kamov Design Bureau of Russia. Compared with the Zhi -9 anti-submarine helicopter usually equipped by China Navy, it has a larger body, can carry more oil, detection equipment and weapons, and has a longer battery life.
electronic equipment
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.
Operational intelligence command system
The 168 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 has been speeded up to 100M fast Ethernet, which has greatly improved the real-time performance, network capacity, network analysis and modeling, reliability and so on.
radar system
Le Tai anti-ship missile guidance radar: This radar is the standard equipment of Russian modern destroyer SS-N-22 anti-ship missile. Working in D/E/F frequency band, it is mainly equipped on large and medium-sized warships such as modern class and fearless class of Russian navy. It is mainly used for mid-course radar guidance of anti-ship missiles, and also has the ability of air-to-sea search. The radome is a long sleeve with a diameter of 3.2 meters and a height of 4.5 meters, and the top is round. A circular paraboloid reflector is installed in the hood, and the radar control distance is within 120km.
However, the ship 168 is not equipped with Russian SS-N-22 missile, so the device is also considered to be able to guide C-803 missile. On the one hand, it shows that the system is universal, on the other hand, it can reduce the labor intensity of ship-borne helicopters to a certain extent, which is more conducive to the play of combat effectiveness.
Wired radar and air defense guidance radar: 168 The search radar equipped on the destroyer is the Russian "roof" three-coordinate air/sea search radar.
"Roof" radar is also the main equipment of the Russian navy today, which is widely equipped on various types of escort ships and has very advanced performance.
It works in E/H frequency band, slot antennas are installed obliquely back to back, and the scanning rate is twice that of unilateral radar. The radar not only has the ability to detect air and sea targets, but also has the functions of air control and low-altitude blind compensation. Its main features are strong anti-electronic interference ability, high degree of automation and good cost performance.
168 is equipped with the latest Mae-5. On the basis of the original model, the emission power of MAE-5 has doubled to 90kW, and the maximum effective distance is still 300 km, but the detection range of fighter and missile has increased by 20%, reaching 230 km and 50 km respectively.
In addition, the 168 ship is also equipped with a set of 5 17 yagi antenna array long-range air/sea early warning radar, which was improved from the old Soviet Union 5 15 radar in the 1950s, and adopted an old yagi frame antenna, but the equipment has been fully upgraded.
Although the 5 17 radar has no stable base, its accuracy will decrease under strong winds and waves, but it has little influence on the long-range radar with a search distance of 350km. Moreover, the wide beam used by this radar seems to be more effective in detecting disappearing aircraft, so the China Navy still uses it today.
The radar has strong anti-jamming ability, can work in an extremely complex electronic environment, can search for a distance of 180 km, and can detect stealth targets. This kind of radar is generally equipped on Chinese naval vessels, which can be said to be the specimen equipment of Chinese navy.
Air defense guidance radar: 168 ship is equipped with four F-band MR-90 "front cover" fire control radars to control Skilly system equipped with SA-N- 12 air defense missiles.
168 ship is also equipped with 1 347G fire control radar, I-band for anti-ship missiles and 100 mm naval guns, 2 EFR- 1 "cereal light radars, 1 RM- 1290 navigation radar, and J.
