a latest” Akizuki “class guided missile destroyer built by Mitsui Engineering & Shipbuilding Co., Ltd. of Japan, in August 22 In the Japanese Maritime Self-Defense Force base Wu held a naming, and influent ceremony notice the maritime staff supervision

Japan’s defense ministry released on August 10 built by Mitsui Engineering & Shipbuilding Co., Ltd. of Japan, a latest Autumn Moon class guided missile destroyer, will be held on August 22 in the Japanese Maritime Self-Defense Force base Wu the naming and influent ceremony (Sina Editor’s note: You have to water). Aboard the guided missile destroyer after it was launched, marking Japan’s four “Akizuki” class generic missile destroyer all the construction is completed. Japanese Maritime Self-Defense Force the missile destroyers team has been the strongest in Asia.

According to public information, “Akizuki” class destroyers equipped ATECS advanced technical operational command system, the system including a phased array radar, high-speed data processing systems and shipboard combat systems.

combat system integrates advanced battle command system OYQ-11, FCS-3A radar system around OQQ-22 integrated anti-submarine systems, and NOLQ-3D Type electronic warfare control system. FCS-3A is a Japanese-made air defense radar system consists of two main components: First, dual-band and multi-mode radar system; fire control system. First OYQ-11 advanced combat command subsystem using distributed computing architecture with AN/UYQ-70 workstations and 16 data link, to be able to receive and process information from a variety of weapons systems, ship weapons system can cooperate the implementation of the anti-aircraft, anti-ship, anti-submarine and electronic warfare.

the class frigates equipped with the the sea combat troops of the Japanese Maritime Self-Defense Force warships conventional equipment (belonging to the C4I system), the system can be coordinated operations through satellite communications terminal and the other ships of the Maritime Self-Defense Force.

air defense systems

“Akizuki” class destroyers equipped with an FCS-3A-type active phased array radar, in the C-band is introduced FCS-3 radar of regional air defense capability improved. The radar installation with the same US-made Aegis system, the four antenna array surface, installed in the ship’s superstructure around omnidirectional coverage and the ability to fight against saturation attacks. FCS-3 the size of the surface of the antenna array is 1.6 m x1.6 m, which contains 1600 signal transmitter/receiver module, radar maximum detection range of up to 200 km and can simultaneously track 300 targets. FCS-3 antenna array element number of these indicators is roughly equivalent to half of the OPS-24 (Japan developed in the late 80s of the last century active phased array radar), its weight must be less than OPS-24, which can be equipped to a higher place (in the case of maintaining the center of gravity height), to expand the scope of detection range and ship-to-air missile interceptor.

In fact, the US-made Aegis system is powerful, but there are also weaknesses that low-altitude, low altitude detection capacity is insufficient. This is because the heavier weight of the phased array antenna, the Aegis radar antenna weighs more than five tons, installed in ships higher cause ships center of gravity is too high to affect the seaworthiness of the ship’s radar detection range and antenna height is proportional to the height of the target, “Aegis” system of low-altitude target detection range is very limited. According to the data, the U.S. Navy Arleigh Burke-class destroyers for the detection distance of 5 meters from the surface of the water and flying anti-ship missiles, less than 30 km. In addition, U.S. warships equipped with the standard 2 “ship to air missile intercept targets need to climb to higher heights in order to accumulate enough energy, in order to maintain the high mobility, which leads to the minimum intercept distance increased weight in the high-speed anti-ship missile interceptor is very unfavorable. FCS-3A-type phased array radar developed in Japan will help improve the situation.

“Akizuki” class destroyer equipped with a 32 unit MK41 missile vertical launching system capable of firing the ship to air missile, the Evolved Sea Sparrow “64 Beitan. The missile is “command + relay INS + the last paragraph of the semi-active radar complex guidance FCS-3A in the C-band, and can not provide the last paragraph of the radar illumination,” Akizuki “class destroyer is an X-band radar front. FCS-3A active phased array radar and the combination of the Evolved Sea Sparrow “makes” Akizuki “class destroyer with both” single-ship air defense, but also to participate in the fleet air defense to provide protection for the consort. The ship is also equipped with two 20-mm Phalanx close-in system to intercept short-range missiles, rockets, and fixed-wing aircraft flying at low altitude.

anti-ship systems

“Akizuki” class destroyers equipped 1 the OPS-20C-90-style sea search radar and two quadruple installed (SSM -1B) anti-ship missile launchers. 90 anti-ship missile launchers Type 88 (SSM-1) ship launcher, missile is 5.1 meters long, 0.35 meters in diameter and has a launch weight of 660 kg, equipped with high-explosive penetrating warhead, inertia + radar + end infrared imaging guidance system, the effective range of 150-200 kilometers. 90 anti-ship missile is Japan’s self-developed second generation of ship-to-ship missiles, to ship Beitan eight similar shape with US-made Harpoon anti-ship missile, with fan-launch capability, available on the 20 kilometers of the surface of the water target locking, the missile flight cruising height of 30 meters, before approaching the target to fall to 5-6 meters, 3 km from the target before diving attack suddenly jumped again.

“Akizuki” class destroyer is also equipped with a MK45 type 127 mm caliber gun, the gun rate of fire of 16-20 rounds per minute, with a range of 24 km.

anti-submarine system

“Akizuki” class destroyers equipped integrated anti-submarine OQQ-22 to hull sonar and OQR-3-towed array sonar system 16 transmitter unit the MK41 vertical launcher, capable of firing RUM-139 and TYPE-7 type ASROC missile. RUM-139 anti-submarine rocket carrying the MK45-V, MK50 torpedoes and nuclear depth charge three different anti-submarine weapons. “ASROC missile uses solid rocket propulsion, warhead MK46Mod5 anti-submarine torpedoes, a range of 20 kilometers, attack submarines underwater 40-1000 meters.

“Akizuki” class destroyer is also equipped with two 97-type rotating triple 324-mm torpedo tubes, capable of firing MK46Mod5 anti-submarine torpedoes and 73 light anti-submarine torpedoes, torpedo range of about 11 km.

In addition, “Akizuki class destroyers equipped with the SH-60K helicopter is also anti-submarine weapon, the helicopter anti-submarine task usually carry two 97 anti-submarine torpedoes or MK64 depth charges, 97 anti-submarine torpedoes Dual Speed ??sailing (Low Speed ??Search/high-speed attack), equipped with large powerful shaped charge warheads, not only to attack the high-speed targets and diving goals, but also enhance the ability to deal with submarines in shallow waters.

Japanese construction “Akizuki” class missile destroyer, nominally has been in service for more than 20 years, “First Snow” class destroyers to replace, to meet the demand of the new round of fleet adjustment and upgrade “eighty comprehensive combat capability of the Fleet “enhance the ability to perform offshore operations under cover of shore-based aircraft.

In recent years, Japan and its neighboring countries in the relevant islands friction escalating its tight fiscal situation remains Bo Jukuan construction of large warships, trying to strengthen its maritime control, to ensure that its so-called “Ocean great power” status, but often make irresponsible remarks on China’s national defense construction. Chinese Defense Ministry spokesman stressed that Japan vigorously develop armaments, strengthen the southwestern islands military deployment and manufacture of tensions in the region frequently on the issue of sovereignty disputes with its neighbors, and has given rise to the height of the Asia-Pacific countries, including China, on August 2 concern and worry. Hope that the Japanese side draw lessons from history, cautious and abide by the commitment to take the road of peaceful development, to reflect on their own military security policy to improve the transparency of military development, do more to enhance with its neighbors and mutual trust is conducive to regional peace and stability thing.
