Shipboard Helicopter Operations
Shipboard helicopter operations is the use of techniques which allows operation of rotary wing aircraft from naval vessels. In the case of military vessels the operations also include tactics and associated weapons and troops. Landing a helicopter on the flight deck of what is sometimes a small ship in heavy seas presents the pilot with a challenges that include: deck movement, turbulent airflows, and using control systems that were not necessarily designed for the marine environment. Flight operations of shipboard helicopter operations include preparing the aircraft and crew for the mission, cargo and ordnance handling (for armed helicopters), passenger supervision, aircraft departure, communications with the ship during the mission and recovery. Apart from the more routine passenger and cargo transportation missions, shipboard helicopter operations are used by civilian and military operators to conduct search and rescue missions, while what for the civilian operators is of ...

Kamov Ka-31
The Kamov Ka-31 (NATO reporting name Helix) is a military helicopter originally developed for the Soviet Navy and currently in service in Russia, China, and India in the naval airborne early warning and control role. As with all Kamov helicopters except the Ka-60/-62 family, the Ka-31 has co-axially mounted contra-rotating main rotors. The airframe of the Ka-31 is based on the Kamov Ka-27. One visually distinctive feature of the Ka-31 is the large antenna of the early-warning radar, which is either rotating or folded and stowed under the fuselage. The second is the reduction of the bulky electro-optical sensory suite beneath the cockpit. The landing gear retracts in order to prevent interference with the radar. Design and development The Kamov design bureau was asked by the Soviet Navy to begin the development of an early-warning helicopter in 1985. A carrier-capable early-warning aircraft, the Yakovlev Yak-44, was already in development, but it would not be deployable ...

Liberty Ship
Liberty ships were a class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Though British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945 (an average of three ships every two days), easily the largest number of ships ever produced to a single design. Their production mirrored (albeit on a much larger scale) the manufacture of "Hog Islander" and similar standardized ship types during World War I. The immensity of the effort, the number of ships built, the role of female workers in their construction, and the survival of some far longer than their original five-year design life combine to make them ...

Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A marginal sea of the Atlantic, with limited water exchange between the two water bodies, the Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The " Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula. The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Evacuation
Medical evacuation, often shortened to medevac or medivac, is the timely and efficient movement and en route care provided by medical personnel to wounded being evacuated from a battlefield, to injured patients being evacuated from the scene of an accident to receiving medical facilities, or to patients at a rural hospital requiring urgent care at a better-equipped facility using medically equipped air ambulances, especially helicopters. Examples include civilian EMS vehicles, civilian aeromedical helicopter services, and military air ambulances. This term also covers the transfer of patients from the battlefield to a treatment facility or from one treatment facility to another by medical personnel, such as from a local hospital to a trauma center. History The first medical transport by air was recorded in Serbia in the autumn of 1915 during First World War. One of the ill soldiers in that first medical transport was Milan Rastislav Štefánik, a Slovak pilot-volunteer who w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Replenishment
Vertical replenishment, or VERTREP, is a method of supply of seaborne vessels by helicopter. The United States Department of Defense defines VERTREP as: ...the transfer of cargo between ships using helicopters. VERTREP is often used to supplement connected replenishment. Weapons loads, generally limited to 1,800 kg (4,000 pounds), are transferred from the supply ship to the flight deck of the amphibious ship. The decided advantage of a VERTREP is that it can effect replenishment without ship-to-ship connection. History The United States Sixth Fleet had developed VERTREP routines in 1962 with SH-3 Sea King helicopters operating from and . Each ship carried one SH-3. At that time, there was some anticipation that nuclear-powered ships might reduce the need for alongside refueling. ''Altair'' performed the first night VERTREP to an aircraft carrier in 1965. Modern United States Navy VERTREP procedures were initiated from in November 1964. ''Sacramento'' embarked two CH-46 Sea Kn ...

Combat Search And Rescue
Combat search and rescue (CSAR) are search and rescue operations that are carried out during war that are within or near combat zones. A CSAR mission may be carried out by a task force of helicopters, ground-attack aircraft, aerial refueling tankers and an airborne command post. The USAF HC-130, which was introduced in 1965, has served in the latter two roles. History The First World War was the background for the development of early combat search and rescue doctrine, especially in the more fluid theaters of war in the Balkans and the Middle East. In the opening fluid stages of the First World War the Royal Navy Air Service Armoured Car Section was formed with armed and armoured touring cars to find and pick up aircrew who had been forced down. When trench warfare made this impossible the cars were transferred to other theatres, most notably the Middle East. In 1915, during the First World War, Squadron Commander Richard Bell-Davies of the British Royal Naval Air Ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Special Forces
Special forces and special operations forces (SOF) are military units trained to conduct special operations. NATO has defined special operations as "military activities conducted by specially designated, organized, selected, trained and equipped forces using unconventional techniques and modes of employment". Special forces emerged in the early 20th century, with a significant growth in the field during the Second World War, when "every major army involved in the fighting" created formations devoted to special operations behind enemy lines. Depending on the country, special forces may perform functions including airborne operations, counter-insurgency, counter-terrorism, foreign internal defense, covert ops, direct action, hostage rescue, high-value targets/manhunt, intelligence operations, mobility operations, and unconventional warfare. In Russian-speaking countries, special forces of any country are typically called , an acronym for "special purpose". In the United ...

Anti-surface Warfare
Anti-surface warfare (ASuW or ASUW) is the branch of naval warfare concerned with the suppression of surface combatants. More generally, it is any weapons, sensors, or operations intended to attack or limit the effectiveness of an adversary's surface ships. Before the adoption of the submarine and naval aviation, all naval warfare consisted of anti-surface warfare. The distinct concept of an anti-surface warfare capability emerged after World War II, and literature on the subject as a distinct discipline is inherently dominated by the dynamics of the Cold War. Categories of anti-surface warfare Anti-surface warfare can be divided into four categories based on the platform from which weapons are launched: * Air (or aviation): Anti-surface warfare conducted by aircraft. Historically, this was conducted primarily through level- or dive-bombing, strafing runs or air-launching torpedoes (and in some cases by suicide attacks). Today, air ASuW is generally conducted by stand-off a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
