OPS-18
OPS-18 is a two-dimensional radar manufactured by Japan Radio Company. It is installed as an anti-water search radar on the Japan Maritime Self-Defense Force, Maritime Self-Defense Force's escort ship. Variations include OPS-18-1 and OPS-18-3. The model numbers of the Maritime Self-Defense Force's electronic devices, including this machine, are generally based on the naming rules for military electronic devices of the U.S. military. It is for radar mounted on surface vessels, for detection / distance direction measurement / search. OPS-3 / OPS-5 The National Safety Agency's Coastal Security Force obtained the AN/SPS-5, AN/SPS-5B radar as equipment for the Bluebird-class minesweeper (Yashima-class minesweeper) provided by the United States in the 1958 plan. In Japan, the OPS-3 was developed based on this AN/SPS-5, and started to be installed on the JDS Akebono (DE-201), JDS Akebono, the first domestic guard ship for the National Safety Agency guards, and the Ikazuchi-class destro ...

Ikazuchi-class Destroyer Escort
The was a destroyer escort (or frigate) class built for the :ja:海上警備隊, Coastal Safety Force (later Japan Maritime Self-Defense Force, JMSDF) in the late 1950s. In the FY1953, the Government of Japan, Japanese government ordered three destroyer escorts, and this class. These vessels were the first indigenous post-World War II Japanese destroyer escorts, but their propulsion systems were different because the JMSDF tried to find the best way in the propulsion systems of future surface combatants. ''Akebono'' was a steamboat, steam-powered vessel, but this class was diesel-powered vessels. So equipment of this class were almost the same as those of ''Akebono'', with two American 3"/50 caliber gun, 3"/50 caliber Mark 21 guns (or Type 54, the Japanese version) with two Mark 22 single mounts controlled by Mark 51 director each, two Bofors 40 mm Automatic Gun L/60, Bofors 40 mm anti-aircraft guns in a dual mount, a Hedgehog (weapon), Hedgehog anti-submarine mortar and eight K ...

JDS Azuma
JDS ''Azuma'' (ATS-4201) was a training support ship of Japan Maritime Self-Defense Force. JS Kurobe was built in 1989 for the purpose of training that could not properly supported by ''Azuma'''s equipment, and so she was removed from the register in 1999 when the new training ship ''Tenryu'' was built. Development and design In 1957, during the Second Defense Build-up Plan, the Maritime Self-Defense Force received 10 KD-2R-3 low-speed target aircraft from the US Navy and began operating unmanned target aircraft (target drones). In the same year, the Landing Ship Support (LSSL) ''Hamagiku'' was incorporated into the Yokosuka District Force and remodeled into an unmanned target aircraft mother boat. After that, the KD-2R-5 was also introduced, but the rear deck of the boat was narrow, which hindered the launch work of the target aircraft, so in 1964, the ''Kusu''-class patrol ship, was newly introduced. It was selected and refurbished as an unmanned target aircraft mother ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

JDS Sōya
JDS ''Sōya'' (MMC-951) was an minelayer of Japan Maritime Self-Defense Force (JMSDF) in the early 1970s. Overview She is the first minelaying ship of the Maritime Self-Defense Force, and in addition to the minelaying mission, she also serve as a flagship for the Mine Warfare Force. When designing, she has a commercial ship structure based on the commercial ship rules in consideration of economic efficiency like JDS Hayase, but in consideration of combat behavior and danger at the time of lightning, she has defensive weapons. It has anti-shock measures similar to those of an escort ship. Due to the laying of mines, the second deck of the ship is considered to be a mine storage for all mines, and the number of mines loaded is 266 for 3000-pound class mines. Due to the larger mine storage, the ship type became a poop deck. There are 6 minelaying rails on the middle deck and 2nd on the upper deck. The rails on the upper deck slope downward along the rear side, and the drop pos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JDS Hayase
JDS ''Hayase'' (MST-462) was a minesweeper for the Japan Maritime Self-Defense Force. Development The Maritime Self-Defense Force purchased the LST-542 class tank landing ship USS Hamilton County, which was retired from the U.S. Navy, and after making certain modifications, she has been operating as a mine sweeper tender JDS Hayatomo since June 1960. The ship was useful as a tender, except that she had plenty of space inside her and was sluggish, but she was completed in 1944 and was an old ship, and it was hoped that her replacement ship will be built. Therefore, a new mine sweeper tender was to be built in the 1969 plan during the Third Defense Build-up Plan. Design In terms of design, JDS Sōya has much in common built in the same year's plan, except this ship has two deck layers. She has a flush deck with a strong shears on the bow and stern. In addition, in order to save construction costs, the hull structure relies on the ship design standards of the Defense Agency, bu ...

Haruna-class Destroyer
The ''Haruna''-class destroyer was a destroyer class built for the Japan Maritime Self-Defense Force (JMSDF) in the early 1970s. These helicopter-carrying destroyers (DDH) were built around a large central hangar which housed up to three helicopters. Originally, the :ja:海上警備隊, Coastal Safety Force and its successor, the JMSDF, had intended to enable its fleet aviation operating capability. In 1960, the Defense Agency planned to construct one helicopter carrier (CVH) with the Second Defense Build-up Plan, but this project was shelved and finally cancelled because the JMSDF changed their plan to dispersing its fleet aviation assets among destroyers, not concentrating in a few helicopter carriers. The Japanese DDH was planned to be a hub with this dispersing fleet aviation concept with their logistics service capability for aircraft. At the beginning, equipment of this class were similar to those of the DDA. All weapons, two 5"/54 caliber Mark 42 gun, 5-inch/54 caliber Mar ...

Chikugo-class Destroyer Escort
The ''Chikugo''-class destroyer escort (or frigate) was a class of destroyer escorts built by the Japanese Maritime Self-Defense Force as the successor of the , with the same ASW mission. This class was followed by . This is the first Japanese destroyer escort class to carry ASROC anti-submarine missiles. The class entered service with ''Chikugo'' in 1971. Eleven ships were constructed and saw service until the mid-1990s and early 2000s. All vessels in the class were retired with ''Noshiro'' being the last to decommission in 2003. Design This class was designed as the modified variant of the , the preceding destroyer escort class. The main anti-submarine weapon was changed from the M/50 ASW rocket launcher to the ASROC Anti-submarine missile. The octuple launcher for ASROC was stationed at the mid-deck, and the entire ship design was prescribed by this stationing. To exploit the range of ASROC, this class was equipped with the long-range low-frequency (5 kHz) bow sonar, OQS- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minegumo-class Destroyer
The ''Minegumo''-class destroyer is a destroyer class of the Japanese Maritime Self-Defense Force, the successor of the . This class derived from its predecessor to be fitted with the QH-50D DASH, the new anti-submarine drone helicopter in return for the removal of the ASROC system. And similarly, it mainly tasked with Anti-submarine warfare. In 1969, after the production of the QH-50D ceased, this class was no longer built and construction of the ''Yamagumo''-class resumed. The JMSDF considered refitting Light Airborne Multi-Purpose System Mk.1 with the Kaman SH-2 Seasprite helicopter in return for the facility of DASH, but this plan was abandoned because of the problem of cost. Finally, the facility of DASH was removed in 1979-82, and Mk.16 GMLS for the ASROC system was fitted. Murakumo was refitted in 1978 for use as a gun trials ship. Rear Mk.33 gun was removed and a new OTO Melara 76 mm The OTO Melara 76 mm gun, marketed as the OTO 76/62 Gun Mount, is a naval au ...

Built between 1964 and 1970, the destroyers were mainly used for anti-submarine warfare (ASW) duties and were designed to operate the Gyrodyne QH-50 DASH, DASH unmanned ASW drone system. The system did not work and was removed from all four ships in 1977. In the mid-1980s, the first two ships of the class were modernized, receiving surface-to-air missile, surface-to-air and anti-ship missiles. The final two ships were scheduled to be modernized, but the program was cancelled. Modernization From 1985 to 1988, ''Takatsuki'' and ''Kikuzuki'' were upgraded with RIM-7 Sea Sparrow, Sea Sparrow surface-to-air missile launchers, Boeing Harpoon, Harpoon missile anti-ship missile launchers, Phalanx CIWS systems (''Kikuzuki'' only), new FCS (FCS-2-12) fire control radar and TASS.

Yamagumo-class Destroyer
The ''Yamagumo'' class are vessels of the Japanese Maritime Self-Defense Force, usually classified as a destroyer, but due to their relatively light displacement, in other sources as a destroyer escort. This class is the successor of the . This class was planned to become the new generation workhorse of the fleet of the JMSDF. In support of this objective, it was equipped with some new generation weapon and sensor systems such as the ASROC anti-submarine rocket and the OPS-11 early warning radar (Japanese equivalent of the American AN/SPS-40 radar). The ''Minegumo''-class destroyer derived from this class as the new DASH The dash is a punctuation mark consisting of a long horizontal line. It is similar in appearance to the hyphen but is longer and sometimes higher from the baseline.
