Eagle-class Patrol Craft
The Eagle-class patrol craft were anti-submarine vessels of the United States Navy that were built during World War I using mass production techniques. They were steel-hulled ships smaller than contemporary destroyers but having a greater operational radius than the wooden-hulled, submarine chasers developed in 1917. The submarine chasers' range of about at a cruising speed of restricted their operations to off-shore anti-submarine work and denied them an open-ocean escort capability; their high consumption of gasoline and limited fuel storage were handicaps the Eagle class sought to remedy. They were originally commissioned USS ''Eagle Boat No.1'' (or 2,3..etc.) but this was changed to PE-1 (or 2,4.. etc.) in 1920. They never officially saw combat in World War I, but some were used during the Allied intervention in the Russian Civil War.Cianflone, Frank A.

Patrol Craft
A patrol boat (also referred to as a patrol craft, patrol ship, or patrol vessel) is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine ("blue water"), estuarine ("green water"), or river ("brown water") environments. Per their name, patrol boats are primarily used to patrol a country's exclusive economic zone (EEZ), but they may also be used in other roles, such as anti-smuggling, anti-piracy, fishery patrols, immigration law enforcement, or search and rescue. Depending on the size, organization, and capabilities of a nation's armed forces, the importance of patrol boats may range from minor support vessels that are part of a coast guard, to flagships that make up a majority of a navy's fleet. Their small size and relatively low cost make them ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secretary Of The Navy
The secretary of the Navy (or SECNAV) is a statutory officer () and the head (chief executive officer) of the Department of the Navy, a military department (component organization) within the United States Department of Defense. By law, the secretary of the Navy must be a civilian at least five years removed from active military service. The secretary is appointed by the president and requires confirmation by the Senate. The secretary of the Navy was, from its creation in 1798, a member of the president's Cabinet until 1949, when the secretary of the Navy (and the secretaries of the Army and Air Force) were by amendments to the National Security Act of 1947 made subordinate to the secretary of defense. On August 7, 2021, Carlos Del Toro was confirmed as secretary of the Navy. From 2001 to 2019, proposals to rename the Department of the Navy to the Department of the Navy and Marine Corps, which would have also renamed the secretary of the Navy to the secretary of the Navy ...

Eagle Boat

In addition to speed and strength, these predators ... of the family Accipitridae. Eagles belong to several groups of Genus, genera, some of which are closely related. Most of the 68 species of eagle are from Eurasia and Africa. Outside this area, just 14 species can be found—2 in North America, 9 in Central and South America, and 3 in Australia. Eagles are not a natural group but denote essentially any kind of bird of prey large enough to hunt sizeable (about 50 cm long or more overall) vertebrate, vertebrates. Description Eagles are large, powerfully-built birds of prey, with heavy heads and beaks. Even the smallest eagles, such as the booted eagle (''Aquila pennata''), which is comparable in size to a common buzzard (''Buteo ...

History Of Science And Technology
The history of science and technology (HST) is a field of history that examines the understanding of the natural world (science) and the ability to manipulate it (technology) at different points in time. This academic discipline also studies the cultural, economic, and political impacts of and contexts for scientific practices. Academic study of history of science History of science is an academic discipline with an international community of specialists. Main professional organizations for this field include the History of Science Society, the British Society for the History of Science, and the European Society for the History of Science. Much of the study of the history of science has been devoted to answering questions about what science ''is'', how it ''functions'', and whether it exhibits large-scale patterns and trends. History of the academic study of history of science Histories of science were originally written by practicing and retired scientists, starting primari ...

Henry Cabot Lodge
Henry Cabot Lodge (May 12, 1850 November 9, 1924) was an American Republican politician, historian, and statesman from Massachusetts. He served in the United States Senate from 1893 to 1924 and is best known for his positions on foreign policy. His successful crusade against Woodrow Wilson's Treaty of Versailles ensured that the United States never joined the League of Nations and his reservations against that treaty influenced the structure of the modern United Nations. Lodge received four degrees from Harvard University and was a widely published historian. His close friendship with Theodore Roosevelt began as early as 1884 and lasted their entire lifetimes, even surviving Roosevelt's bolt from the Republican Party in 1912.

Armistice Of 11 November 1918
The Armistice of 11 November 1918 was the armistice signed at Le Francport near Compiègne that ended fighting on land, sea, and air in World War I between the Entente and their last remaining opponent, Germany. Previous armistices had been agreed with Bulgaria, the Ottoman Empire and Austria-Hungary. It was concluded after the German government sent a message to American president Woodrow Wilson to negotiate terms on the basis of a recent speech of his and the earlier declared "Fourteen Points", which later became the basis of the German surrender at the Paris Peace Conference, which took place the following year. Also known as the Armistice of Compiègne (french: Armistice de Compiègne, german: Waffenstillstand von Compiègne) from the place where it was officially signed at 5:45 a.m. by the Allied Supreme Commander, French Marshal Ferdinand Foch, it came into force at 11:00 a.m. Central European Time (CET) on 11 November 1918 and marked a vi ...

Slipway
A slipway, also known as boat ramp or launch or boat deployer, is a ramp on the shore by which ships or boats can be moved to and from the water. They are used for building and repairing ships and boats, and for launching and retrieving small boats on trailers towed by automobiles and flying boats on their undercarriage. The nautical terms ways and skids are alternative names for slipway. A ship undergoing construction in a shipyard is said to be ''on the ways''. If a ship is scrapped there, she is said to be ''broken up in the ways''. As the word "slip" implies, the ships or boats are moved over the ramp, by way of crane or fork lift. Prior to the move the vessel's hull is coated with grease, which then allows the ship or boat to "slip" off of the ramp and progress safely into the water. Slipways are used to launch (newly built) large ships, but can only dry-dock or repair smaller ships. Pulling large ships against the greased ramp would require too much force. Therefor ...

Arc Welding
Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals, when cool, result in a binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick ("electrode") and the base material to melt the metals at the point of contact. Arc welders can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated. First developed in the late part of the 19th century, arc welding became commercially important in shipbuilding during the Second World War. Today it remains an important process for the fabrication of steel structures and vehicles. Power supplies To supply the electrical energy necessary for arc welding processes ...

The total surface is , and the total volume (measured at the low water datum) is , slightly less than the volume of Lake Baikal (, 22–23% of the world's surface fresh water ...
