Salem Harbor
Salem Harbor is a harbor in northeastern Massachusetts spanning an area north and south of Salem, Massachusetts, Salem. Historically the Salem Harbor was the site of one of the major international ports in the colonies. During the American Revolutionary War, merchant ships were enlisted as privateers, an important role to augment the ill-prepared Continental Navy. In 1790, Salem Harbor was a world-famous seaport and sixth-largest in the United States of America. Now the harbor is used for commercial and recreational purposes and the Salem Maritime National Historic Site is very popular with tourists from around the world. History The harbor was defended by Fort Miller (Massachusetts), Fort Miller in Marblehead, Massachusetts, Marblehead from 1632 to 1865, and by Fort Pickering on Winter Island from 1643 to 1865. Salem merchants defended the colonies during the American Revolutionary War through privateering. When the 13 colonies United States Declaration of Independence, d ...

Seaplane
A seaplane is a powered fixed-wing aircraft capable of takeoff, taking off and water landing, landing (alighting) on water.Gunston, "The Cambridge Aerospace Dictionary", 2009. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called ''hydroplanes'', but currently this term applies instead to Hydroplane (boat), motor-powered watercraft that use the technique of Planing (boat), hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of the investments in airports during the war but mainly because landplanes were less constrained by weather conditions that could result in sea states being too high to operate seaplan ...

Edward Robert Armstrong
Edward Robert Armstrong (1876–1955) was a Canadian-American engineer and inventor who in 1927 proposed a series of "seadrome" floating airport platforms for airplanes to land on and refuel for transatlantic flights. While his original concept was made obsolete by long-range aircraft that did not need such refueling points, the idea of an anchored deep-sea platform was later applied to use for floating oil rigs. Biography * Armstrong was born in 1876 in Guelph, Ontario. * He moved to the United States and worked in Texas in the early 1900s, developing oil-well-drilling machinery. * In 1909 he went to St. Louis, Missouri as an automotive and aviation engineer. * In 1916 he went to DuPont to work on the construction of their nitrocellulose plant in Hopewell, Virginia. He was then promoted to chief of the plant's mechanical research department. * In 1924 he quit DuPont to work full-time on his "seadrome" project. In 1926 he incorporated the "Armstrong Seadrome Development Company ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grumman HU-16 Albatross
The Grumman HU-16 Albatross is a large, twin–radial engined amphibious aircraft, amphibious seaplane that was used by the United States Air Force (USAF), the U.S. Navy (USN), and the U.S. Coast Guard (USCG), primarily as a search and rescue (SAR) aircraft. Originally designated as the SA-16 for the USAF and the JR2F-1 and UF-1 for the USN and USCG, it was redesignated as the HU-16 in 1962. A new build G-111T Albatross with modern avionics and engines was proposed in 2021 with production in Australia to commence in 2025. Design and development An improvement of the design of the Grumman Mallard, the Albatross was developed to land in open-ocean situations to accomplish rescues. Its deep-V hull cross-section and keel length enable it to land in the open sea. The Albatross was designed for optimal seas, and could land in more severe conditions, but required JATO (jet-assisted takeoff, or simply booster rockets) for takeoff in seas or greater.

Martin PBM Mariner
The Martin PBM Mariner was an American Maritime patrol aircraft, patrol bomber flying boat of World War II and the early Cold War era. It was designed to complement the Consolidated PBY Catalina and Consolidated PB2Y Coronado, PB2Y Coronado in service. A total of 1,366 PBMs were built, with the first example flying on 18 February 1939 and the type entering service in September 1940, with the last of the type being retired in 1964. Design and development In 1937 the Glenn L. Martin Company designed a new twin-engined flying boat, the Model 162, to succeed its earlier Consolidated P2Y, Martin P3M and complement the Consolidated PBY Catalina, PBY Catalina and Consolidated PB2Y Coronado, PB2Y Coronado. It received an order for a single prototype XPBM-1 on 30 June 1937.Swanborough and Bowers 1976, p. 318. This was followed by an initial Mass production, production order for 21 PBM-1 aircraft on 28 December 1937.Green 1968, p. 177. To test the PBM's layout, Martin built a ⅜ scale f ...

Air-Sea Rescue
Air-sea rescue (ASR or A/SR, also known as sea-air rescue), and aeronautical and maritime search and rescue (AMSAR) by the ICAO and International Maritime Organization, IMO, is the coordinated search and rescue (SAR) of the survivors of emergency water landings as well as people who have survived the loss of their seagoing vessel. ASR can involve a wide variety of resources including seaplanes, helicopters, submarines, rescue boats and ships. Specialized equipment and techniques have been developed. Both military and civilian units can perform air-sea rescue. Its principles are laid out in the International Aeronautical and Maritime Search and Rescue Manual. The International Convention on Maritime Search and Rescue is the legal framework that applies to international air-sea rescue. Air-sea rescue operations carried out during times of conflict have been credited with saving valuable trained and experienced airmen. Moreover, the knowledge that such operations are being carried o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-submarine
An anti-submarine weapon (ASW) is any one of a number of devices that are intended to act against a submarine and its crew, to destroy (sink) the vessel or reduce its capability as a weapon of war. In its simplest sense, an anti-submarine weapon is usually a projectile, missile or bomb that is optimized to destroy submarines. History Before World War I Prior to about 1890, naval weapons were only used against surface shipping. With the rise of the military submarine after this time, countermeasures were considered for use against them. The first submarine installation of torpedo tubes was in 1885 and the first ship was sunk by a submarine-launched torpedo in 1887. There were only two ways of countering the military submarine initially: ramming them or sinking them with gunfire. However, once they were submerged, they were largely immune until they had to surface again. By the start of the First World War there were nearly 300 submarines in service with another 80 in production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neutrality Patrol
On September 3, 1939, the British and French declarations of war on Germany initiated the Battle of the Atlantic. The United States Navy Chief of Naval Operations (CNO) established a combined air and ship patrol of the United States Atlantic coast, including the Caribbean, on 4 September, President Franklin D. Roosevelt declared the United States' neutrality on 5 September, and declared the naval patrol a Neutrality Patrol.Cressman, p. 2 Roosevelt's initiation of the Neutrality Patrol, which in fact also escorted British ships, as well as orders to U.S. Navy destroyers first to actively report U-boats, then "shoot on sight", meant American neutrality was honored more in the breach than observance. Background Upon declaration of war, the United Kingdom, France, and Germany attempted to restrict their adversaries' ability to import raw materials and manufactured goods. The belligerent navies were deployed to intercept ships capable of carrying such imports. Ships evading enemy nava ... [...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 was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derelict (maritime)
In maritime law, flotsam'','' jetsam'','' lagan'','' and derelict are specific kinds of shipwreck. The words have specific nautical meanings, with legal consequences in the law of admiralty and marine salvage. A shipwreck is defined as the remains of a ship that has been wrecked—a destroyed ship at sea, whether it has sunk or is floating on the surface of the water. Overview A wreck is categorized as property belonging to no apparent owner that either sinks to the seabed or floats on the surface of the water, whether it be intentionally cast overboard or as the result of an accident. The term encompasses the hull of the vessel and its fixtures as well as any other form of object on board, such as cargo and stores, and personal effects of the crew and passengers. This also encompasses the narrower definition of salvage, that is, property that has been recovered from a wreckage, or the recovery of the ship itself. There are a number of factors that contribute to the formation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Search And Rescue
Search and rescue (SAR) is the search for and provision of aid to people who are in distress or imminent danger. The general field of search and rescue includes many specialty sub-fields, typically determined by the type of terrain the search is conducted over. These include mountain rescue; ground search and rescue, including the use of search and rescue dogs; urban search and rescue in cities; combat search and rescue on the battlefield and air-sea rescue over water. International Search and Rescue Advisory Group (INSARAG) is a UN organization that promotes the exchange of information between national urban search and rescue organizations. The duty to render assistance is covered by Article 98 of the UNCLOS. Definitions There are many different definitions of search and rescue, depending on the agency involved and country in question. *Canadian Forces: "Search and Rescue comprises the search for, and provision of aid to, persons, ships or other craft which are, or are fear ...
