JDS Mogami
JDS ''Mogami'' (DE-212) is the second ship of of Japan Maritime Self-Defense Force (JMSDF). Development and design This class was the first JMSDF surface combatant adopted shelter-deck design. Propulsion systems varied in each vessels because the JMSDF tried to find the best way in the propulsion systems of future destroyer escorts. The design concept of this class and the CODAD propulsion system of the ''Kitakami'' class became prototype of them of the latter destroyer escorts and destroyers such as and . The gun system was a scale-down version of the , four 3"/50 caliber Mark 22 guns with two Mark 33 dual mounts controlled by a Mark 63 GFCS.

Mogami River
The is a river in Yamagata Prefecture, Japan. Description and history It is 224 km long and has a watershed of 7,040 km2. It is regarded as one of the three most rapid rivers of Japan (along with the Fuji River and the Kuma River). The river rises from southern Yamagata Prefecture and flows to the north, and turns west at Shinjō and flows into the Sea of Japan at Sakata. Water transportation once flourished on the river and carried local products such as safflowers and rice to the Kansai region. Cultural references The Mogami River appears as an ''utamakura'' in Japanese poetry, with the influential 17th-century poet Matsuo Bashō composing several hokku regarding the river during his travels alongside it. Some were revised as haiku in the memoir of his journeys, including this well-known poem: : ::''samidare o atsumete hayashi Mogami-gawa'' :gathering the rains :of the wet season — swift :the Mogami River :(''trans. Shirane'') The character Yūko Aioi in ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CODAD
Combined diesel and diesel (CODAD) is a propulsion system for ships using two diesel engines to power a single propeller shaft. A gearbox and clutches enable either of the engines or both of them together to drive the shaft. Two advantages over simply using a single, larger diesel engine of the same total power output are that (1) diesel engines have somewhat better specific fuel consumption at 75% to 85% max output than they do at only 50% output, and (2) there is a weight and size advantage to using two higher-speed engines compared to a single lower-speed engine, even with the slightly larger gearbox system.

Training Ship
A training ship is a ship used to train students as sailors. The term is mostly used to describe ships employed by navies to train future officers. Essentially there are two types: those used for training at sea and old hulks used to house classrooms. The hands-on aspect provided by sail training has also been used as a platform for everything from semesters at sea for undergraduate oceanography and biology students, marine science and physical science for high school students, to character building for at-risk youths.

Mark 32 Surface Vessel Torpedo Tubes
Mark 32 Surface Vessel Torpedo Tubes (Mk 32 SVTT) is a torpedo launching system designed for the United States Navy. History The Mark 32 has been the standard anti-submarine torpedo launching system aboard United States Navy surface vessels since its introduction in 1960, and is in use aboard the warships of several other navies. During the FRAM Program, , and destroyers were modernized and fitted with two Mark 32 torpedo tubes on each side of their midship. The torpedo tubes' service extended to multiple other countries such as Mexico, South Korea, Taiwan, Turkey, Egypt and many more due to the fact that decommissioned American ships were bought or transferred over to them throughout the years, notably s. Japan uses the HOS-301 torpedo tubes which are redesignated version of the Mark 32.

Maizuru Naval District
was one of four main administrative districts of the pre-war Imperial Japanese Navy. Its territory included the entire Sea of Japan coastline from northern Kyūshū to western Hokkaidō. History The strategic importance of the location of Maizuru, Kyoto, Maizuru and its potential for development into a military port for operations in the Sea of Japan towards Korea, Russia and even China was early recognized by the Imperial Japanese Navy. During the administrative re-organization of the Navy in 1889, Maizuru was designated as the headquarters of the ''Fourth Naval District'' (, ''dai-yon kaigunku''), and its harbor was dredged, a Breakwater (structure), breakwater constructed and docking facilities for warships were established. With the First Sino-Japanese War, the port was fortified with the addition of heavy coastal artillery.

Commissioned (ship)
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing correct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
