Foreign Media: China battleship remote sensor anti-submarine capacity (1)

March 30, message: Asian Defense Review network recently published entitled "striving to respond to the article of submarine warfare", including China, Japan, Korea, India, Asia-Pacific countries of antisubmarine warfare capability.

The article alleges that although China is expanding its naval power, but its still limited antisubmarine warfare capabilities, this is because the Chinese Navy ships lacked the remote sensor.

The article argues that while the Pacific economic prosperity increasingly rely on maritime trade, but the submarine threat posed by the increasing.

This can be from Pacific submarine number change seeing a second ground slightly. It is estimated that only the value of the Asian market submarine $ 320 billion, and approximately 10 countries is being or is about to purchase approximately 90 submarines. Of these, Viet Nam, who recently returned from Russia bought 6 "kilo"-636-diesel-electric submarines.

The limited capacity of Chinese antisubmarine warfare

Currently, Viet Nam has further to Malaysia, officially entered the country with submarines, and Thailand is most likely will follow the Viet Nam to join in.

In addition, India, Indonesia, Pakistan, Korea, Singapore and Taiwan all intends to expand its submarine fleet, and the United States Navy plans to its vast number of submarines to deploy to the Pacific. Australia also plans to double the number of submarines, after all: Naval 6 "Collins" submarines, a maximum of only two to be able to run at any time.

The article points out that at present relatively good sensor that is specifically designed for the North Atlantic operations SLF towed array sonar, Sonar's best Induction ranges up to 100 nautical miles (185 km).

However, the sensor system needs a few kilometers of the array, this will require larger warships and equipped with a powerful winch. Furthermore, to better detect effects, low speed cruise ship must be relative. However, while this sensor can detect targets, but in general it is not specific to lock its position. But to get a target location, sailing ship can only twists and turns.

Japan maritime self-defense force plan composed by two modes, four fleet is to deploy a model of a "pass-through" destroyer ", an Aegis destroyers and frigates; another model is deploying an Aegis destroyers and frigates.

Destroyer can provide for Navy advanced electronics technology and weapons, as well as to provide the "blue water" in Japan.

In addition, Korea has a similar program, but its equipment was very different.

Korea Navy KDX-1 destroyers (explore Earth King level) and KDX-2 destroyers (Zhong-Wu Shun Lee Robinson-level public) are installed combat management systems, towed array sonar and light helicopter multifunction destroyers, also, KDX-2 destroyers with Astrid Locke antisubmarine rocket. The destroyers to Korea provides remote anti-submarine. In contrast, Korea's "USAN" class frigates while installing a new hull mounted sensor (hull-mountedsensor), but because of the lack of external sonar (off-boardsonar) and helicopters, so most of them only as a coastal patrol duties. However, it is expected that from 2011 to Korea fleet FFX frigates, will remedy these deficiencies and provide direct for Korea Navy commander of the force.

The article says, in contrast, although China is expanding its naval power, but its antisubmarine warfare capability is still very limited, with the result that the Navy's activities is limited to the continental shelf around — indeed, the Chinese Navy is almost never the area participating in large-scale military exercises.

At present, a total of 27 of the Chinese Navy destroyers, most of which are equipped with lightweight torpedoes and anti-submarine rocket launchers; however, they installed sensors are mostly limited to hull mounted-medium frequency sonar, only two of the "Shanghai" (052) destroyer equipped with variable depth sensor. Although the majority of these modern frigates, Destroyers, also featuring a light helicopter (such as the DC-9 or card 28), but most of them lack the remote sensor. Although the Chinese ship electronic equipment information is very limited, but it seems that many anti-submarine warfare for warships are missing, and their management systems are often only a tactical data system — the system while providing the relevant tactical situation data, but cannot be the weapon system. The two systems and manpower operations not skilled is probably very little Chinese Navy fleet for long-distance maritime patrol.

India fighters voyage limits the advantages of remote sensor

As a strong opponent of China, India and Japan signed a cooperation agreement between the sea and have a different philosophy of submarines.

India naval 8 destroyers are multifunctional destroyers and attaches great importance to the defense. All of these ships are fitted with than the Chinese Navy sensing distance greater hull mounted-sonar, at the same time they are also equipped with variable depth sonar. However, with the Chinese Navy destroyers, India destroyers will only install with tactical data processing system, which were not equipped with a complete operational management system. However, India's "Delhi"-class "Bombay" guided missile destroyer is installed with Tellis company active/passive towed array sonar. In addition, India Russia destroyer also carry design of antisubmarine rocket launchers and heavy (53 cm diameter) remote torpedo, which includes both anti surface ships and submarines. Currently, India is using a variety of light helicopter, replacing the aging Sea King "helicopter", these lightweight, heavy helicopter including the new Dhruv (former advanced light helicopter), card 28 helicopter or "Leopard" helicopter, but the light helicopter flight only old aircraft a few half, this greatly limits the advantages of remote sensor.

The article points out that India is currently the most common antisubmarine warfare platform is 12 frigates, most of which are based on the United Kingdom's "Leander-class frigates.

These and destroyers, frigates and installed using similar sensor/carrier-based aircraft, and most also carry a light torpedoes. In addition, India is currently still under construction at least four Project28-class light cruiser-initially it is antisubmarine warfare cruisers, but has now been described as a multifunctional lightweight Xunyang-Ship. These light cruisers will have an active/passive towed array sonar and light helicopters, although they would use light torpedoes and rocket launchers of conventional mixed mode, but obviously the Cruiser is limited to the implementation of coastal operations or island Territories.
