Egyptian Navy
The Egyptian Navy (), also known as the Egyptian Naval Forces, is the maritime branch of the Egyptian Armed Forces. It is the largest navy in the Middle East as well as Africa, and is the twelfth largest (by the number of vessels) navy in the world. The navy protects more than 2,000 kilometers of coastline of the Mediterranean Sea and the Red Sea, defense of approaches to the Suez Canal, and it also supports for army operations. The majority of the modern Egyptian Navy was created with the help of the Soviet Union in the 1960s. The navy received ships in the 1980s from China and Western sources. In 1989, the Egyptian Navy had 18,000 personnel as well as 2,000 personnel in the Coast Guard. The navy received ships from the United States (US) in the year 1990. US shipbuilder Swiftships has built around 30 boats for the Egyptian Navy including mine hunters, survey vessels, and both steel and aluminium patrol boats. History Egypt has had a navy since Ancient Egyptian times. The Anci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OTO Melara 76 Mm
The OTO Melara 76 mm gun, marketed as the OTO 76/62 Gun Mount, is a naval autocannon built and designed by the Italian Defense contractor, defence company OTO Melara. It is based on the OTO Melara 76/62C and evolved toward 76/62 SR and 76/62 Strales. The system is compact enough to be installed on relatively small warships. Its high rate of fire and the availability of several types of ammunition make it capable of short-range Missile defense, anti-missile Point-defence, point defence, Anti-aircraft warfare, anti-aircraft, Anti-surface warfare, anti-surface, and Fire support, ground support. Ammunition includes Armour-piercing ammunition, armour-piercing, Incendiary ammunition, incendiary, Fragmentation ammunition, directed fragmentation effects, and a guided round marketed as capable of destroying maneuvering anti-ship missiles. It can be installed in a stealth Gun turret, cupola. The OTO Melara 76 mm has been widely exported, and is in use by sixty navies. It was fa ...

Anti-ship Missile
An anti-ship missile (AShM or ASM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea-skimming variety, and many use a combination of inertial guidance and active radar homing. A large number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. Many anti-ship missiles can be launched from a variety of weapons systems including surface warships (also referred to as ship-to-ship missiles), submarines, bombers, fighter planes, patrol planes, helicopters, shore batteries, land vehicles, and, conceivably, even infantrymen firing shoulder-launched missiles. The term surface-to-surface missile (SSM) is used when appropriate. The longer-range anti-ship missiles are often called anti-ship cruise missiles. Several countries are also developing anti-ship ballistic missiles. Etymology Both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...

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 ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship’s carrying capacity, as it excluded the small, often unusable volume contained in its overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to ...

Royal Navy Of Oman
The Royal Navy of Oman (), abbreviated RNO, is the maritime component of the Royal Armed Forces of the Sultanate of Oman. Given its long coastline and strategic location along the Indian Ocean, as well as being close to the Strait of Hormuz, the Royal Navy is one of the priorities of the government of Oman. It has a fleet of gunboats, fast missile boats and support, training, cargo and hydro-graphical survey vessels, which can be deployed to defend the territorial waters and coastline of Oman as well as protect tankers passing through the Strait of Hormuz. The Royal Navy's headquarters are in Seeb, near the Muscat International Airport. A modernization program is ongoing, with the objective of creating a first-rate fleet. Similarly, the Royal Oman Police's fleet, which operates smaller range boats and patrol crafts, is being updated due to raising tensions in the region. The origin of the Royal Navy of Oman is traceable to the reign of Imam Ghassan bin Abdullah (807–824 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
