JDS Azuma
JDS ''Azuma'' (ATS-4201) is 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 Target may refer to: Physical items * Shooting target, used in marksmanship training and various shooting sports ** Bullseye (target), the goal one for which one aims in many of these sports ** Aiming point, in field artillery, fi ...). 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agatsuma Gorge
is a two to three kilometer long ravine on the upper and middle reaches of the Agatsuma River in the towns of Highashiagatsuma and Naganohara, Gunma Prefecture, Japan. It has been designated a National Place of Scenic Beauty since 1935. It is featured on the 'ya' card in Jomo Karuta. Overview The Agatsuma River flows through western Gunma Prefecture, crossing into Gunma via the Torii Pass from Nagano Prefecture and flowing eastward to join the Tone River at Shibukawa. A portion of the river passes through an area of eroded Miocene andesite and tuff breccia, forming a narrow ravine. The difference in height of the old route of Japan National Route 145 and the river surface is 50 meters. The river is curved and has a variety of landscapes such as pools, waterfalls, and strangely shaped rock formations. Surrounded by deciduous broad-leaved forests, it is a famous spot for viewing autumn leaves. In addition, natural concentrations of azaleas flowers in spring draw many vi ...

Torpedo Launcher
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although other sizes of torpedo tube have been used: see Torpedo classes and diameters. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within the submarine into the sea at the ambient ...

5"/54 Caliber Mark 42 Gun
The Mark 42 5"/54 caliber gun (127mm) is a naval gun (naval artillery) mount used by the United States Navy and other countries. It consisted of the Mark 18 gun and Mark 42 gun mount. United States naval gun terminology indicates the gun fires a projectile in diameter, and the barrel is 54 calibers long (barrel length is 5" × 54 = 270" or 6.9 meters.) In the 1950s a gun with more range and a faster rate of fire than the 5"/38 caliber gun used in World War II was needed, therefore, the gun was created concurrently with the 3"/70 Mark 26 gun for different usages. The 5"/54 Mk 42 is an automatic, dual-purpose (air / surface target) gun mount. It is usually controlled remotely from the Mk 68 Gun Fire Control System, or locally from the mount at the One Man Control (OMC) station. The self-loading gun mount weighs about including two drums under the mount holding 40 rounds of semi-fixed case type ammunition. The gun fires projectiles at a velocity of .Baile ...

JDS Kusu
The first USS ''Ogden'' (PF-39) was a in commission from 1943 to 1945. Originally classified as PG-147, she was the first ship of the United States Navy to be named for Ogden, Utah. She later served in the Soviet Navy as ''EK-10'' and in the Japan Maritime Self-Defense Force as ''Kusu'' (PF-1), ''Kusu'' (PF-281), ''YAS-50'' and ''YAC-22''. Construction and commissioning ''Ogden'' was laid down at the Consolidated Steel Corporation shipyard in Los Angeles, California, on 21 May 1943, launched on 23 June 1943, sponsored by Miss Margaret S. Shelton, and commissioned at San Diego, California, on 20 December 1943.

Tacoma-class Frigate
The ''Tacoma'' class of patrol frigates served in the United States Navy during World War II and the Korean War. Originally classified as gunboats (PG), they were reclassified as patrol frigates (PF) on 15 April 1943. The class is named for its lead ship, , a Maritime Commission (MARCOM) S2-S2-AQ1 design, which in turn was named for the city of Tacoma, Washington. Twenty-one ships were transferred to the British Royal Navy, in which they were known as Colony-class frigates, and twenty-eight ships were transferred under Lend-Lease to the Soviet Navy, where they were designated as ''storozhevoi korabl'' ("escort ships"), during World War II. All ''Tacoma''-class ships in US service during World War II were manned by United States Coast Guard crews. ''Tacoma''-class ships were transferred to the United States Coast Guard and various navies post-World War II. Design In 1942, the success of German submarines against Allied shipping and the shortage of escorts with which to protect ...

Landing Craft Support
The Landing Craft, Support (Large) were two distinct classes of amphibious warfare vessels were used by the United States Navy (USN) in the Pacific and the Royal Navy in World War II. The USN versions which were later reclassified Landing Ship Support, Large also performed radar picket duty and fire fighting. US Navy Vessels The original designation for the ships was LCS(L)(3), which stood for "Landing Craft Support (Large) Mark 3". In 1949 the class was reclassified to "Landing Ship Support, Large" (LSSL). The United States Navy had to have the designation LCS(L) because there was also a smaller class named LCL, that were built mainly for rescue and smoke laying during amphibious operation. Design and manufacture A total of 130 were made. Three different ship building yards did the construction: George Lawley & Son (Neponset, Massachusetts); Commercial Iron Works (Portland, Oregon); and Albina Engine Works (Portland, Oregon).

Target Drone
A target drone is an unmanned aerial vehicle, generally remote controlled, usually used in the training of anti-aircraft crews. One of the earliest drones was the British DH.82 Queen Bee, a variant of the Tiger Moth trainer aircraft operational from 1935. Its name led to the present term "drone". In their simplest form, target drones often resemble radio-controlled model aircraft. More modern drones may use countermeasures, radar, and similar systems to mimic manned aircraft. More advanced drones are made from large, older missiles which have had their warheads removed. In the United Kingdom, obsolete Royal Air Force and Royal Navy jet and propeller-powered aircraft (such as the Fairey Firefly, Gloster Meteor and de Havilland Sea Vixen used at RAE Llanbedr between the 1950s and 1990s) have also been modified into remote-controlled drones, but such modifications are costly. With a much larger budget, the U.S. military has been more likely to convert retired aircraft or old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Japan Maritime Self-Defense Force
, abbreviated , also simply known as the Japanese Navy, is the maritime warfare branch of the Japan Self-Defense Forces, tasked with the naval defense of Japan. The JMSDF was formed following the dissolution of the Imperial Japanese Navy (IJN) after World War II. The JMSDF has a fleet of 154 ships, 346 aircraft and 50,800 personnel. History Origin Following Japan's defeat in World War II, the Imperial Japanese Navy was dissolved by the Potsdam Declaration acceptance. Ships were disarmed, and some of them, such as the battleship , were taken by the Allied Powers as reparation. The remaining ships were used for repatriation of the Japanese soldiers from abroad and also for minesweeping in the area around Japan, initially under the control of the ''Second Bureau of the Demobilization Ministry''. The minesweeping fleet was eventually transferred to the newly formed Maritime Safety Agency, which helped maintain the resources and expertise of the navy. Japan's 1947 Constitution ...
