HNoMS Helge Ingstad (F313)
HNoMS ''Helge Ingstad'' was a of the Royal Norwegian Navy. The vessel was ordered on 23 June 2000 and constructed by Navantia in Spain. The ship was launched on 23 November 2007 and commissioned on 29 November 2009. Named for Helge Ingstad, a Norwegian explorer, the ''Fridjtof Nansen'' class are capable of anti-air, anti-submarine and surface warfare. On 8 November 2018, HNoMS ''Helge Ingstad'' was in collision with the tanker in Norwegian waters just outside Sture Terminal. ''Helge Ingstad'' was severely damaged in the collision and beached. On 13 November 2018, the ship sank where she had run aground and became a constructive total loss. She was raised in a salvage operation from 27 February 2019 to 3 March 2019. In June 2019 after it was deemed uneconomical to repair her, it was decided that she would be scrapped. Design and description The design of the s began in 1997. Based on the design, Izar (later Navantia) of Spain and Lockheed Martin were chosen to construc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helge Ingstad
Helge Marcus Ingstad (30 December 1899 – 29 March 2001) was a Norwegian explorer. In 1960, after mapping some Norse settlements, Ingstad and his wife archaeologist Anne Stine Ingstad found remnants of a Viking settlement in L'Anse aux Meadows in the province of Newfoundland in Canada. They were thus the first to prove conclusively that the Icelandic/Greenlandic Norsemen such as Leif Erickson had found a way across the Atlantic Ocean to North America, roughly 500 years before Christopher Columbus and John Cabot. He also thought that the mysterious disappearance of the Greenland Norse Settlements in the 14th and 15th centuries could be explained by their emigration to North America. Helge Ingstad died at Diakonhjemmet Hospital in Oslo at the age of 101. Early life Helge Ingstad was the son of Olav Ingstad (1867–1958) and Olga Marie Qvam (1869–1946) in Meråker, Nord-Trøndelag. His father was municipal engineer in Tromsø and held the title of factory supervisor. He w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Launching System
A vertical launching system (VLS) is an advanced system for holding and firing missiles on mobile naval platforms, such as surface ships and submarines. Each vertical launch system consists of a number of ''cells'', which can hold one or more missiles ready for firing. Typically, each cell can hold a number of different types of missiles, allowing the ship flexibility to load the best set for any given mission. Further, when new missiles are developed, they are typically fitted to the existing vertical launch systems of that nation, allowing existing ships to use new types of missiles without expensive rework. When the command is given, the missile flies straight up far enough to clear the cell and the ship, then turns on to the desired course. A VLS allows surface combatants to have a greater number of weapons ready for firing at any given time compared to older launching systems such as the Mark 13 single-arm and Mark 26 twin-arm launchers, which were fed from behind by a ...

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

NH90
The NHIndustries NH90 is a medium-sized, twin-engine, multi-role military helicopter. It was developed in response to NATO requirements for a battlefield helicopter which would also be capable of being operated in naval environments. The NH90 was developed and is manufactured by NHIndustries, a collaborative company owned by Airbus Helicopters, Leonardo (formerly AgustaWestland) and Fokker Aerostructures. The first prototype conducted its maiden flight in December 1995; the type first entered operational service in 2007. As of June 2022, the NH90 has logged 327,053 flight hours in the armed forces of thirteen countries. The NH90 is the first production helicopter to feature entirely fly-by-wire flight controls.Perry, Dominic"Rotor club: Our top 10 most influential helicopters." ''Flight International'', Flight Global, 21 November 2014. There are two main variants, the Tactical Transport Helicopter (TTH) for army use and the navalised NATO Frigate Helicopter (NFH); each custom ...

Long Range Acoustic Device
A long-range acoustic device (LRAD) is an acoustic hailing device (AHD), sound cannon and sonic weapon developed by Genasys. It has been used as a method of crowd control, which has caused permanent hearing damage, having an extremely high decibel capacity (up to 160 dB measured at one meter from the device). Other uses have included for negotiations in siege situations to deal with piracy at sea; for mass notification during natural disasters or other emergencies; and by defense forces, including several navies. History In October 2000 the , an American guided missile destroyer, was bombed in a terrorist attack by al-Qaeda operatives, using a small boat packed with explosives. The naval personnel on Cole were unable to be sure that their messages could be heard by the approaching boat at a sufficient distance to possibly avert the attack. The ship was badly damaged, 17 U.S. Navy sailors killed and 37 injured. Following this attack, navies around the world made s ...

Heavy Machine Gun
A heavy machine gun (HMG) is significantly larger than light, medium or general-purpose machine guns. HMGs are typically too heavy to be man-portable (carried by one person) and require mounting onto a weapons platform to be operably stable or tactically mobile, have more formidable firepower, and generally require a team of personnel for operation and maintenance. There are two generally recognized classes of weapons identified as HMGs. The first are weapons from World War I identified as "heavy" due to the weight and cumbersomeness of the weapons themselves, which prevents infantrymen from transporting on foot, such as the M1917 Browning machine gun. The second are large-caliber ( 12.7×99mm, 12.7×108mm, 14.5×114mm, or larger) machine guns, pioneered by John Browning with the M2 machine gun, designed to provide increased effective range, penetration and destructive power against covers, vehicles, aircraft and light buildings/fortifications beyond the standard-caliber ...

M2 Browning Machine Gun
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otobreda 76 Mm
The OTO Melara 76 mm gun is a naval gun built and designed by the Italian 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 anti-missile point defence, anti-aircraft, anti-surface, and ground support. Ammunition includes armour-piercing, incendiary, directed fragmentation effects, and a guided round marketed as capable of destroying manoeuvring anti-ship missiles. It can be installed in a stealth cupola. The OTO Melara 76 mm has been widely exported, and is in use by sixty navies. It was favoured over the French 100mm naval gun for the joint French/Italian project and FREMM frigate. On 27 September 2006 Iran announced it had started mass production of a naval gun named the Fajr-27, which is a reverse-engineered OTO Mela ...

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive hydraulic shock. Most depth charges use high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a " nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a surface ship, or anot ...

Sting Ray Torpedo
The Sting Ray is a British acoustic homing lightweight torpedo (LWT) manufactured by GEC-Marconi, who were later bought out by BAE Systems. It entered service in 1983. Design and development In the 1950s the Royal Navy was equipped with British designed and built Mk 30 air-dropped torpedoes. These were passive homing weapons which relied on detecting the noise from submarine targets. However, as submarine noise levels decreased these weapons became ineffective. A design for a British Mk 31 torpedo which would have used active echo-location sonar failed to receive Government approval for production. US Mk 44 torpedoes were purchased for the Royal Navy in the 1960s to fill this role, and later replaced by US Mk 46 torpedoes. A desire not to be dependent on US torpedo purchases led to a research programme starting in 1964 to develop a British torpedo. Initially designated Naval and Air Staff Requirement (NASR) 7511, it was (much later in the late 1970s) designated the Sting ...

Torpedo Tube
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 ...
