Chinese Destroyer Hangzhou
''Hangzhou'' (136) is a Type 956E destroyer of the People's Liberation Army Navy. Development and design The project began in the late 1960s when it was becoming obvious to the Soviet Navy that naval guns still had an important role particularly in support of amphibious landings, but existing gun cruisers and destroyers were showing their age. A new design was started, employing a new 130 mm automatic gun turret. The ships were in length, with a beam of and a draught of . The Chinese People's Liberation Army Navy Surface Force (PLAN) had two modified ''Sovremenny''-class destroyers delivered in December 1999 and November 2000. In 2002, the PLAN ordered two improved versions designated 956-EM. The first vessel was launched in late 2005, while the second was launched in 2006. All four vessels were commissioned to the East Sea Fleet. Project cost: 600 million US$ (mid-1990s price) was the price paid for Project 956A (two ships), and 1.4 billion US$ (early-2000s pri ...

Kamov Ka-27
The Kamov Ka-27 (NATO reporting name 'Helix') is a military helicopter developed for the Soviet Navy, and as of 2024 is in service in various countries including Russia, Ukraine, Vietnam, China, South Korea, and India. Variants include the Ka-29 assault transport, the Ka-28 downgraded export version, and the Ka-32 for civilian use. Design and development The helicopter was developed for ferrying and anti-submarine warfare. Design work began in 1969 and the first prototype flew in 1973. It was intended to replace the decade-old Kamov Ka-25, and had to have identical or smaller external dimensions than its predecessor. Like other Kamov military helicopters it has coaxial rotors, removing the need for a tail rotor. In total, five prototypes and pre-series helicopters were built. Series production started at Kumertau in July 1979, and the new helicopter officially entered service with the Soviet Navy in April 1981. The Ka-27 has a crew of three with a pilot and navigator both stati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 it is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and Electronics, electronic systems, Galley (kitchen), 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Launched (ship)
Ceremonial ship launching involves the performing of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back millennia, 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 the end-on la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keel Laying
Laying the keel or laying down is the formal recognition of the start of a shipbuilding, 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 a ship's life; the others are Ceremonial ship launching, launching, Ship commissioning, commissioning, and Ship decommissioning, decommissioning. Earlier, 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 ...

United States Dollar
The United States dollar (Currency symbol, symbol: Dollar sign, $; ISO 4217, currency code: USD) is the official currency of the United States and International use of the U.S. dollar, several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish dollar, Spanish silver dollar, divided it into 100 cent (currency), cents, and authorized the Mint (facility), minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The U.S. dollar was originally defined under a bimetallism, bimetallic standard of (0.7734375 troy ounces) fine silver or, from Coinage Act of 1834, 1834, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equivalence to gold was revised to $35 per troy ounce. In 1971 all links to gold were repealed. The U.S. dollar became an important intern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Sea Fleet
The Eastern Theater Command Navy (东部战区海军, ETCN) is a formation of China's People's Liberation Army Navy (PLAN) and the naval component of the Eastern Theater Command. The ETCN was reorganized from the East Sea Fleet (ESF) by 2016. Currently Wang Zhongcai is the commander of the ESF and Mei Wen it's political commissar. History The PLAN was formed toward the end of the Chinese Civil War. In March 1949, Zhang Aiping of the Third Field Army was ordered by the Central Military Commission (CMC) of the Chinese Communist Party to create a naval force from the field army. Zhang's only previous naval experience was organizing an irregular riverine force near Hongze Lake in 1941 and leading it in a successful campaign against local bandits. The PLAN was created on 21 April when Zhang established the East China Military Region Navy, or East China Navy (ECN), with a thirteen-member headquarters, and he was formally appointed by the CMC as the ECN's commander and commissar ...

People's Liberation Army Navy Surface Force
The People's Liberation Army Navy Surface Force is the surface warfare branch of China's People's Liberation Army Navy (PLAN), consisting of all surface ship, surface vessels in operational service with the PLAN. The PLAN Surface Force operates 661 ships organized into three naval fleet, fleets: the North Sea Fleet, the East Sea Fleet and the South Sea Fleet. Since the late 20th century, the People's Liberation Army Navy has been turning away from its traditional focus on coastal warfare, coastal and littoral warfare and instead prioritizing the development of blue-water navy, blue water capabilities. This led to a significant reduction in overall fleet numbers as the PLAN has replaced a larger number of smaller ships with a smaller number of larger, more capable and versatile ships, including destroyers, frigates, corvettes, amphibious warfare ships and large auxiliary ships. However the growing number of "blue water" capable warships has risen, and fleet numbers are projected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draft (ship)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if depl ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cora ...

Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several operational roles from search-and-destroy to ocean escort to sea denial. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—usually fulfilled by frigates or sloop-of-war, sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre- ...
