Japan Maritime Self-Defense Force’s comprehensive strength ranks first in Asia, anti-submarine warfare capability after the United States p> P-3C anti-submarine patrol aircraft to detect submarines comprehensive search using various means, such as machine equipment AN/APS a 115 frequency agile radar 360. Search in three sea conditions for submarine periscope detection range of 15 knots, the submarine snorkel detection range of 36 nautical miles. In addition, the Maritime Self-Defense Force’s SH-60J “Sea Hawk” helicopters are also equipped with an APS 124 radar and other anti-submarine detection equipment.

air anti-submarine attack enemy submarines is the core part. P-3C anti-submarine patrol aircraft can carry eight a 324 mm MK46 8 MK54 torpedoes or depth bombs and other anti-submarine weapons, combined with P-3C anti-submarine patrol aircraft with a variety of advanced search facilities, target tracking, high accuracy positioning, so a big threat to the submarine.

Japan Maritime Self Defense Force fleet of surface ships mainly by short-range anti-submarine warfare mission destroyers and frigates to bear, its surface ships have advanced anti-submarine detection equipment and assault weapons, ship-based sonar search of the largest exploration potential distance of about 35 nautical miles, anti-submarine weapons are the “ASROC” anti-submarine missiles and MK46-5 lightweight anti-submarine torpedoes.

Submarine in the water, the Japanese main battle various types of naval sonar equipment, mainly the United States sonar imitation, every ship is equipped with main battle ships mostly 2-3 sonar, including ship shell + drag type or drag-type ship shell + + darker type. In order to solve the problem of limited search range, Japan from the U.S. introduction SQR a 18A tactical towed array sonar, the array length 223 m, diameter 8.3 cm, drag cable length 1600 meters. Attack submarine in the water, in addition to “Ishikari” class frigate, the Japanese Maritime Self-Defense Force destroyers and frigates are equipped with the other a “ASROC” anti-submarine missile launchers. In addition, without exception, all destroyers and frigates are equipped with two triple mounted 324 mm anti-submarine torpedo tubes.

Japanese Maritime Self-Defense Force submarine mainly responsible for medium-range anti-submarine warfare missions, a total of three submarines of its active 19. The role of submarine sonar systems in the 100 nautical miles away, anti-submarine weapons system mainly uses the Japanese Type 80 or Type 89 533 mm wire-guided torpedoes, the maximum range of 50 km, the maximum of depth 600 meters. Currently, all Japanese submarines were equipped with ZQQ series and ZQR 1 two kinds of sonar systems. ZQQ series in Japan in the United States AN/BQS-4 sonar hull sonar made on the basis of imitation, such as “spring tide” level and “pro-surge” level on the ZQQ a submarine hull sonar 5B, in the , low-frequency range, and the active/passive target search, range 5 to 15 nautical miles. Test proved that the “tide” class submarines, after the installation of such a sonar, the quiet submarine has a good detection results.

Indian Yu Jian large anti-submarine nets

India’s Yonhap News Agency reported that India’s federal defense for defense, said Minister of State 帕拉姆拉詹 for strengthen the “blue water” ocean-going capability, India’s commitment to provide more for the Navy for undersea surveillance and anti-submarine warfare platform. Western observers generally will Rajan talks with the Indian media earlier, when the so-called “China’s submarine or will enter the Indian Ocean,” the statement linked, suggesting that the Indian Navy has begun to prepare for China to do practical preparation.

since early this year, the Indian media began to hype the so-called “China’s nuclear submarine stationed in Hainan Island,” the topic, the “Chinese submarines may enter the Indian Ocean” has become India’s most worried about. Indian Navy suddenly feel thorn in the side, so a series of measures to build three-dimensional anti-submarine nets frequently introduced. First, the United Kingdom, “Jane’s Defense Weekly,” disclosed the secret Indian army in the adjacent Sunda Strait Thanjavur build anti-submarine aircraft base, followed by India, the U.S. government has declared for the Boeing P-8I long-range anti-submarine aircraft development projects. In addition, the Indian Navy in the east coast of Africa, Madagascar listening station opened to the composition of the anti-submarine monitoring network covering the Indian Ocean. Media that these actions reflect the Indian Navy submarines to China may appear in the traditional Indian sea of ??panic.

Despite the Indo-Pakistan war in 1971, a frigate in the Indian state of no knowledge of the submarine sunk by Pakistan and India after World War II became the first submarine hit countries suffered, but the Indian Navy is still not anti-submarine capabilities to the strategic level. In equipment and tactical training system on the Indian Navy is still a “passive” anti-submarine tactics.

because of financial and technical reasons, India does not like the United States, Japan and other developed countries, as laid along the long coastline, sophisticated underwater monitoring system, even as Cochin, Visakhapatnam and other Indian naval warships gathered lack of adequate facilities for underwater listening. This means that India’s hard-to-grasp movements of rival submarines in the Indian Ocean, in the event of war, the Indian Navy can not take a strategic initiative to attack, to pre-emptive strike to destroy enemy submarines or the potential to be blocked in the harbor. Currently, the Indian Navy fleet anti-submarine operations is generally taken, with real-time monitoring capabilities take time.

years, why not build a comprehensive anti-submarine network to become the focus of the Indian Navy, is due to the Indian Ocean before the submarine force is not strong enough. In addition to India’s more than 20 submarines, the Navy’s only Pakistan and Iran, six submarines, the former is only a submarine home port in Karachi, India’s fleet of war can easily be blocked, which basically does not open out the Strait of Hormuz, can underwater anti-submarine force, said India has been able to meet the needs of the time.

the case in the absence of pressure, the Indian anti-submarine and U.S. Navy Coast Guard system only reached the level of the 1970s. India is now the most important strategic anti-submarine weapon is the Russian-made eight figure a 142 and five IL-38 long-range anti-submarine patrol aircraft, their performance does not lag behind, enough to cover the combat radius of Western Australia, India to get the opponent underwater information on the activities of the main platform. However, due to the small number of equipment, coupled with natural environmental factors, its intelligence surveillance was not ideal.

Switzerland “International Fleet” magazine analysis, with their own “wedging the Indian Ocean, many facing the sea,” land of geographical advantages, India has been basically set up a tight-knit coastal observation points to monitor surface ships and out of the Indian Ocean countries. If India plans huge anti-submarine networks can be successfully implemented, will greatly enhance India’s anti-submarine capabilities. But you really want real-time control of the Indian Ocean following the movement, the Indian Navy also need more long-term effort.

fleet of destroyers and frigates form itself has a variety of sonar devices, and anti-submarine missiles and carrier-based anti-submarine torpedoes as the inner fire, and 40-50 nautical miles away from the periphery of the fleet are a number of Ka- a 28, and other anti-submarine Sea King helicopter with the formation of the outer ring anti-submarine fire. Anti-submarine helicopters usually a group of three machines, an inverted triangle formation, there is the threat of enemy waters to search for each helicopter search of the effective width of 5 nautical miles. Find enemy submarines, the formation or to rely on carrier-based anti-submarine helicopter carrying weapons firing, and strive to be destroyed. Anti-submarine fleet is in fact anti-submarine operations in relatively conservative mode. Indian Navy admitted to the large Indian Ocean, the fleet you want to rely on a few tracks of his country in the region as Haidilaozhen submarine operations. Military Digest No. 8
