OPS-11
OPS-11 is a two-dimensional radar manufactured by Mitsubishi Electric. It is installed as an anti-aircraft search radar on the Maritime Self-Defense Force's escort ship, and it was the first model originally developed by Japan after World War II for this purpose. Variations include OPS-11B and OPS-11C. 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. Overview In developing the radar since the prototype electric probe, it was planned to model the AN/SPS-40, which was planned to be provided by the United States for the JDS Wakaba (former Imperial Japanese Navy Matsu-class destroyer). However, due to the delay in the provision of the actual product, most of the actual development was done independently by the Japanese side. For this reason, ...

Takatsuki-class Destroyer
The ''Takatsuki''-class destroyer was a series of four destroyers constructed for and operated by the Japan Maritime Self-Defense Force. 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. ''Mochizuki'' and ''Nagatsuki'' were in the upgrade program, but were eventuall ... [...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 ...

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. The most common versions are the endash , generally longer than the hyphen ... equipped version, but after the QH-50D DASH was scrapped, the JMSDF decided on resuming the construction of t ...

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 ...

JS Hatakaze
The ''Hatakaze''-class of guided-missile destroyers is a third generation class of vessels in service with the Japan Maritime Self-Defense Force (JMSDF). They were the first of the JMSDF's ships to have gas-turbine propulsion. The core weapon suite of the class is similar to that of the preceding , but various improvements were made in many areas. Most notable are those that allow the ''Hatakaze''-class to function as a group flagship. Normally, this duty resides with a larger type of ship, but, in case of their absence due to repairs, accident, or battle damage, the ''Hatakaze'' design allows for it to function as a command ship. ''Hatakaze'' destroyers operate the OYQ-4-1 type tactical control system. Its weapon systems include the Standard missile surface-to-air missile, anti-submarine rockets, the RGM-84 Harpoon anti-ship missile, two Mark 15 20 mm CIWS gun mounts, two torpedo A modern torpedo is an underwater ranged weapon launched above or below the water surfa ...
