What are the combat systems of Japanese "Gaobo" class destroyers?

Compared with the village rain class, the improvement of the high wave class equipment is mainly the vertical launch system of the main gun and missile. Whose main gun is used in the rain level of Otto village? Melella 62 times caliber 76 mm gun changed to Otto for King Kong class? Boleda's 54-caliber 127mm gun, though relatively heavy, is nearly 40 tons, but its firing rate is twice that of the American MK-45 127mm gun, reaching 45 rounds per minute. When using a non-extended range bomb, its maximum range is 23 kilometers, and it can launch various kinds of bombs developed by all NATO countries for this caliber gun.

After using this gun, not only the power of the shell is greatly improved, but also the use space of various guided guns is correspondingly increased and the precision strike ability is enhanced after the caliber is increased. If it uses laser-guided projectiles or even GPS-guided projectiles, it is quite effective for land-based point targets.

In the future landing operations, when the front-line troops are blocked by point targets, as long as the position of the target is notified or the target is irradiated with a laser illuminator, the standard precision strike can be completed.

The cost of guided artillery shells is much lower than that of various missiles, and the firing rate of multi-ship volley is not as good as that of long-range missile attacks. As for the vertical launching system, the MK48 system and MK4 1 system used in the village rain level are unified as MK4 1, which are arranged behind the main gun on the front deck. The original MK48 platform has been changed into an anti-ship missile launching platform.

After this improvement, the configuration mode of sea sparrow air defense missile and Aslock anti-submarine missile is much more flexible than before, and the ratio of the two missiles can be freely configured according to the conditions of mission content and the strength of the other side.

The MK4 1 vertical launch system can also equip the future Maritime Self-Defense Force with cruise missiles. Because Japan can't develop this kind of long-range offensive weapon at this stage for various reasons, it is very likely that it will carry out the precise strike task against long-range land targets alone in future wartime, and once necessary, it can only use American-made equipment.

The MK4 1 system could have used cruise missiles such as Tomahawk. As for the early technical and tactical training, it can be carried out through various joint training, drills, drills and personnel exchanges between Japan and the United States, which is very frequent.

Assuming that land targets on the Korean peninsula or other areas are to be attacked in the future, this "Gaobo" alone can carry 29 cruise missiles, and its attack power is still quite strong. This can also make up for the time difference of the long-range attack of the US Navy at the beginning of the war to some extent.

Anti-ship capability

This change is mainly reflected in the 127 mm main gun. According to the statistics of naval battles since World War II, 3-4 rounds127mm shells can effectively damage1000t ships, and at least 20 rounds of 76mm shells are needed to achieve the same effect.

Like Otto? The shell of the Boleda 127mm gun weighs 32kg, while Otto? Melella's 76 mm gun weighs only 6 kg, and the weight ratio of ammunition fired per minute is 1.440 kg: 5 10 kg. Moreover, the 1.27mm cannonball can be guided by a ship-borne helicopter, so it is almost unnecessary to use a "whaling fork" or an airborne missile when dealing with small ships, that is, it can achieve almost the same accuracy, but the range is slightly insufficient compared with missiles.

Air defense and anti-submarine capability

Due to the MK4 1 system, the air defense and anti-submarine capabilities of this class of ships are quite flexible, but there is no qualitative change, especially in the air-launched anti-ship missiles against the other side. If the other side can have Tu -22M backfire or similar bombers, combined with different types of airborne anti-ship missiles, such as active radar guided missiles and anti-radiation missiles, it can break through the outer air defense network provided by King Kong.

In this case, two kinds of high-wave air defense equipment, namely "dense array" and "sea sparrow", can only play the role of picking up the missing, and can only rely on the OLT-3 electronic jammer made by Fujitsu and the MK36 chaff launcher for soft countermeasures.

In terms of anti-submarine capability, it is said that the sonar of its hull is a new type of equipment, but the specific model and performance have not yet been announced. The Mk46-5 torpedo used in the launch tube of its 3-joint torpedo changed the original single-speed system of MK-46 series torpedo into a two-speed system, and adopted low speed in the search stage, thus enhancing the ability to deal with submarines in shallow water. Moreover, the seeker can correct the channel to determine whether the sound detected by sonar is a real pulse echo, which can compensate for the reduction of signal-to-noise ratio caused by the installation of anechoic tiles and deal with the problem more effectively.

When dealing with deep-water submarines, the warhead of the "Aslock" missile can be changed to Mk50 torpedo, and the maximum underwater speed can reach 55~60 knots, which has a certain counter-production effect on the foreseeable underwater threats around Japan.

powerplant

The high wave level adopts propulsion mode. Its four main engines are divided into two types, and the engine room is arranged on the left and right sides. The front is the first engine room, which is the port propulsion shafting, and the back is the second engine room, which is the starboard propulsion shafting, so the left transmission shaft is longer than the right transmission shaft. The computer room is equipped with two main engines and corresponding deceleration system. The configuration mode is that the first computer room is equipped with 1 and 2 hosts, and the second computer room is equipped with 3 and 4 hosts.

In which 1 and No.4 main engines are LM2500 gas turbines of American general dynamics company, and the single output power is 12. 1 MW, and No.2 and No.3 main engines are British rolls-royce. The single output power of "Spee" gas turbine of Rolls-Royce Company is 9.9 MW, and the total speed of the whole ship reaches 44. 1 MW.

Because the two main engines can run at different speeds because of the speed, and the propeller with large diameter and oblique alternating pitch is used to slow down, the noise in the water is greatly reduced, which is beneficial to anti-submarine warfare. The steering gear is the same as the original destroyer, and there is no big change.

The ship is equipped with three generators, the power is 1.5 MW, and the electricity consumption can be met by two generators at ordinary times. The third generator is a backup system. 1 No.2 generators are installed in the corresponding first and second engine rooms, and the third main generator is installed in the generator room independently set at the rear.

A 600 kW auxiliary generator is installed in the auxiliary engine room of the engine room, which is mainly used to ensure the power supply when the ship berths. In order to improve the survivability of warships, the switchboard room and IC room are overlapped, and a set of independent ones is set in front and back of the hull, so as to ensure that warships can still have certain combat capability after being hit in wartime to the greatest extent.

Main control room is located on the second deck in the center of the hull. Like destroyers in the past, it is also used as an emergency command room. In addition to the main console, the control room is also equipped with auxiliary console, power console and emergency monitoring system, where various auxiliary machines can be started and controlled to monitor the operation of the engine room.

The bottom cabin is an auxiliary engine room, which is equipped with a series of auxiliary equipment such as auxiliary boiler, seawater desalination device, various pumps and anti-rolling wings. Unlike American ships, the bathroom and air conditioner on board are powered by steam provided by auxiliary boilers. The bridge is equipped with a bridge control system, which can accurately reflect the situation of warships and engine rooms.

Comprehensive influence

According to the establishment of the Maritime Self-Defense Force, its mobile strike force is the escort fleet, and the main surface ship force of the escort fleet is the destroyer formation. The escort fleet consists of four escort formations, each consisting of eight warships, divided into flagship and three escort formations, and each escort formation has two or three destroyers of the same level or type.

In this way, a typical "eight? Eight "fleet-a helicopter destroyer, two air defense destroyers, five general destroyers, and nine Murayama-class ships built before, so that each escort fleet of the Maritime Self-Defense Force is assigned to two or three general destroyers with VLS system. According to the Murayama-class model, it is possible to build about 8 high-wave-class ships, basically ensuring that each escort group deploys two more.

It can be predicted that the "Gaobo" class will be regarded as "eight" within 2~3 years after its service. The general destroyer of the capital ship of the Eighth Fleet will basically complete full combustion power and VLS, while the new eighth? The combat capability of the Eighth Fleet will rise to a new level.

The new "eight"? The Eighth Fleet is more aggressive, and even has the characteristics of "from sea to land". We should look at the appearance of high wave level from a systematic perspective, and regard it as a link between the old and the new in the equipment update of the Maritime Self-Defense Force, and perhaps we can get more information or enlightenment.
