JS Asuka
JS ''Asuka'' (ASE-6102) is an experimental ship of the Japan Maritime Self-Defense Force. The vessel was constructed by Sumitomo Heavy Industries of Tokyo, Japan and was launched on 21 June 1994. ''Asuka'' was commissioned on 22 March 1995 and since then has conducted performance confirmation tests for integrated navigation systems. Development and design The hull is a blocking deck type hull. After a new surface ship sonar (OQS-XX) was installed on the bow and bottom, the bow was to be kept away from OQS-XX so as to avoid interference during anchoring and to move the breaking wave generation position as far back as possible. It protrudes sharply. The OQS-XX consists of a bow dome cylindrical array (CA) and a long flank array (FA) on the bottom of the ship, but due to budget constraints, the FA was only equipped on one side. The bridge structure consisted of four layers, at the top of which was a radar equipment room with four active phased array (AESA) antennas for the Fir ...

Bow (ship)
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military ...

Ships Built By Sumitomo Heavy Industries
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were con ...

Its total area is . Geography Ōshima Town covers the island of Izu Ōshima, in the Izu Islands, Izu archipelago in the Philippine Sea, south of central Tokyo. Climate History It is uncertain when human settlement first began on Ōshima, but archaeological finds from the Jōmon period have been discovered, and the island is mention from early Nara period documents. It is mentioned in historical records for its many volcanic eruptions. After the start of the Meiji period, in 1878, the island came under the control of Tokyo-fu and was organized into six villages (Okada, Motomura, Senzu, Nomashi, Sashikiji and Habuminato) under Oshima subprefecture on April 1, 1908. The six villages were merged to form Ōshima Town on April 1, 1955. In the mid-1930s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vestas Sailrocket
The ''Vestas Sailrocket'' was built to capture the sailing speed record competing in the B-class for 150 to 235 square feet of sail. It is piloted by the project leader Paul Larsen and sponsored by Danish wind turbines manufacturer Vestas. In 2008 the first version reached a reported unofficial speed of , before crashing. After being upgraded to a second version, the ''Vestas Sailrocket 2'' began a campaign to break speed records in November 2012 off Walvis Bay, Namibia. On 12 November, it made a run over a distance, then on the 16th. It attained on a one-mile run on the 18th and simultaneously on 500m. On 24 November, with wind speeds at roughly , it ran the 500m course at with a peak. Both records are ratified by the World Sailing Speed Record Council (WSSRC) for the 500m and the mile.

2011 Tōhoku Earthquake And Tsunami
The occurred at 14:46 JST (05:46 UTC) on 11 March. The magnitude 9.0–9.1 (M) undersea megathrust earthquake had an epicenter in the Pacific Ocean, east of the Oshika Peninsula of the Tōhoku region, and lasted approximately six minutes, causing a tsunami. It is sometimes known in Japan as the , among other names. The disaster is often referred to in both Japanese and English as simply 3.11 (read in Japanese). It was the most powerful earthquake ever recorded in Japan, and the fourth most powerful earthquake in the world since modern record-keeping began in 1900.

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] |
Active Electronically Scanned Array
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR). The AESA is a more advanced, sophisticated, second-generation of the original PESA phased array technology. PESAs can only emit a single beam of radio waves at a single frequency at a time. The PESA must utilize a Butler matrix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
