JS Nichinan
JS ''Nichinan'' (AGS-5105) is the only ship of her type of oceanographic research ship for the Japan Maritime Self-Defense Force. Development With the shift to passive anti-submarine warfare, the collection of marine environmental data is required for efficient execution of maritime operations, and seafloor topography / sediment, tidal currents / geomagnetism, and water temperature / salt content, etc. Marine weather was interrelated and needed to be measured precisely. For this reason, the Maritime Self-Defense Force built the in the plan of 1967, and in 1969, it newly formed the Marine Operations Corps as its operation unit and started marine environment information activities. After that, in the 1950s, and were installed, and ocean observations were carried out with a system of four vessels. Of these, this ship was planned as a substitute for the 42AGS, which was scheduled to be removed in the latter half of the 1990s, and was approved for construction in the 1996 pl ...

Mashū-class Replenishment Ship
The ''Mashū''-class is a series of replenishment oilers of the Japan Maritime Self-Defense Force (JMSDF). They were built from 2002-04. The ships have the hull classification symbol, hull designator AOE. The ''Mashū''-class was designed as an enlarged, improved version of the Towada-class replenishment ship, ''Towada''-class fast combat support ships. The vessels are capable of mounting two Phalanx CIWS by design. They have been in commission from 2004 onwards.

Hayabusa-class Patrol Boat
The ''Hayabusa''-class is a guided missile patrol boat class of the Japan Maritime Self-Defense Force (JMSDF). Six boats were built between 2002-04. The Japan Maritime Self-Defense Force initially built three hydrofoil missile boats of the PG 1-go class between 1993-95. The ''Hayabusa''-class was designed to correct the issues that arose with the preceding class. After an incident off the Noto Peninsula involving a North Korean spy ship, two ships of the class were included in the 1999 fiscal year plan. Outline Hull The boat's displacement was enlarged to four times that of the PG 1-go class to improve seaworthiness. The maximum speed was increased to improve the ability to intercept ships; however, the speed increase proved to be difficult to implement. Both double-hull and single-hull designs were considered; the single-hull design was selected for reasons of hull strength and seaworthiness. The hull is long and narrow with a V-shaped bottom, allowing for a high hull speed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uraga-class Mine Countermeasure Vessel
The ''Uraga'' class was a series of 2 mine countermeasure vessels for the Japan Maritime Self-Defense Force. They were both built and commissioned in the 1990s. Development It was built as an alternative to JDS Hayase and JDS Sōya, as the class of ships combined the functions of both. Reflecting the experience of Hayase dispatched to the Persian Gulf, the function of the ship was improved, and the newly introduced air minesweeper (Mk.105) was introduced and acquired from the dock. A helicopter support function for performing air minesweeping was also required. As a result, they became considerably larger, and although they were finally made slightly smaller than originally planned to be 5,600 tons, the amount of wastewater is still doubled compared to 44MST. The construction of the name ship was approved for 29.7 billion yen in the 1994 plan, which is the latter half of the 2003 medium-term defense. The construction of the second ship was also approved in the next year's pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ōsumi-class Tank Landing Ship
The ''Ōsumi'' class (), is a Japanese tank landing ship. The class is also known as the ''Oosumi'' class. While the Japan Maritime Self-Defense Force (JMSDF) describes the ''Ōsumi'' class as tank landing ships (LSTs), they lack the bow doors and beaching capability traditionally associated with LSTs. Functionally, their well deck makes the ''Ōsumi'' class more like a dock landing ship (LSD). As of 2024 there are three ''Ōsumi'' vessels active with the Japanese Maritime Self-Defence Force. Design and specifications ''GlobalSecurity.org'' noted in its report on the ''Ōsumi'' class that "the program originated in a proposal for a small carrier for defensive and mine countermeasures (MCM) purposes, but this was deemed politically unacceptable, and the project was reworked as an amphibious ship" (actually a "Maritime Operational Transport", see below). Later the JMSDF returned to the idea with helicopter carriers with the larger . The ''Ōsumi'' class increases its ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kongō-class Destroyer
The of guided-missile destroyers in the Japan Maritime Self-Defense Force are equipped with the Aegis Combat System, and is the first of few ship classes outside the United States to have that capability. Following a decision made in December 2003, Japan is upgrading their ''Kongo''-class destroyers with Aegis Ballistic Missile Defense System. The upgrade involves a series of installations and flight tests to take place from 2007 to 2010. JS ''Kongo'' was the first ship to have the BMD upgrade installed. Background The JMSDF built under FY1960 program and started shipboard operation of surface-to-air missiles. She had been equipped with analog-version of the Tartar Guided Missile Fire Control System. A fully-digitized system was adopted on the next-generation , and later a combat direction system based on the Naval Tactical Data System was added. Nevertheless, the JMSDF estimated that its fleets would not survive against Soviet airstrikes, especially Tupolev Tu-22M bombers ...

Takanami-class Destroyer
The is a class of destroyer serving with the Japan Maritime Self-Defense Force (JMSDF). This warship is the slightly modified class of second-generation, general-purpose destroyers of the JMSDF. Background Since FY1991, the JMSDF started construction of the second-generation, , . These destroyers are generally satisfactory for the fleet, but there is some discontent. From FY1998 onwards, a slightly modified version that corrected these dissatisfaction points was to be built: ''Takanami'' class. Design The hull design is generally based on that of the ''Murasame'' class. However, the weapons mounted are different, and as a result, the internal structure has also been changed. The large lattice mast affected the stealthiness of the ''Murasame'' class, so in ''Takanami'' class, it was planned to change to two small masts, but that was not implemented. Although their displacement become slightly increased, there was no change to their main engines, as it was not a big difference ...

Akizuki-class Destroyer (2010)
The ''Akizuki'' class of destroyers of the Japan Maritime Self-Defense Force is intended to escort the and helicopter destroyers, and safeguard the other Aegis-capable warships such as the and . The destroyer provides defense against surface, airborne and undersea threats. The class was initially designated as "19DD", referring to a date on the Japanese calendar, specifically the 19th fiscal year of the Heisei period (2007). Design The hull structure was based on that of the s. There are many small improvements, such as cleaner lines to reduce the radar signature and decoys for torpedoes; but the principal changes can be summed up as more powerful engines, sensors, sonar and the indigenous ATECS battle management system that has been called the ''Japanese AEGIS''. The main gas turbine engines are standardized on a higher-powered version of the Rolls-Royce Spey SM1C, in contrast to the combination of Rolls-Royce SM1C and General Electric LM2500 turbines used in the ''Takanami ...
