Japanese Patrol Vessel Shikishima
The ''Shikishima'' is the lead ship of of the Japan Coast Guard (JCG). She was built by Ishikawajima-Harima Heavy Industries, Tokyo. Planned to guard plutonium transport ships, the ''Shikishima'' class is the largest and heaviest-equipped patrol vessel of the JCG. With her cruising capacity, she can make voyages from Japan to Europe without making any calls. She is the only JCG ship equipped with anti-air radar and Oerlikon 35 mm twin cannons, so she has increased anti-air firepower. Usually, PL (Patrol vessels, Large) have only a navigation radar and a single-mounted 35 mm or 40 mm autocannon. And the JM61 20 mm Vulcan on the single-mounted remote weapon system later became a model for the 20 mm RFS (Remote Firing System), which is on modern PMs and PSs such as the PS. The OPS-14 2D air search radar is the Japanese counterpart of the American AN/SPS-49.

Asagiri-class Destroyer
The is a class of destroyer, serving with the Japan Maritime Self-Defense Force (JMSDF). It was the second class of first-generation general-purpose destroyers of the JMSDF. Background The JMSDF started construction of a since FY1977. This was the first class of under the eight ships / eight helicopters concept. In this concept, each flotilla would be composed of one helicopter destroyer (DDH), five general-purpose destroyers (DD), and two guided-missile destroyers (DDG). However, due to constraints such as budget, the design of the ''Hatsuyuki'' class was compelled to compromise in terms of C4I function, resistance, and durability. Thus, destroyers to be built after FY1983, ''Asagiri'' class were changed to an evolved design with expanded hull and enhanced equipment. Design The hull is an enlarged type of ''Hatsuyuki'' class, and the hull form is of the shelter deck style. Also, as the latter batch of the ''Hatsuyuki'' class, the upper structure is made of steel, but since it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JS Setoyuki
JS ''Setoyuki'' (DD-131/TV-3518) was a ''Hatsuyuki''-class destroyer of the Japanese Maritime Self-Defense Force.
