Fleet Problem X
The Fleet Problems are a series of naval exercises of the United States Navy conducted in the interwar period, and later resurrected by Pacific Fleet around 2014. The first twenty-one Fleet Problems — labeled with roman numerals as Fleet Problem I through Fleet Problem XXI — were conducted between 1923 and 1940. They were usually once-a-year exercises in which U.S. naval forces would engage in mock battles. One or more of the forces would play the part of a European or Asian navy. They were the culmination of the Navy's annual training maneuvers. Fleet Problem XXII, scheduled for 1941, was canceled because of the rising tensions with Japan that led to the US' entry into World War II. Following the outbreak of war, Fleet Problems underwent a prolonged hiatus, with other names being used to describe large American naval exercises. However, the term was revived in the 21st century under Admiral Scott H. Swift, with Fleet Problem XXIII through XXVIII taking place in the Pacific ...

Chesapeake Bay
The Chesapeake Bay ( ) is the largest estuary in the United States. The Bay is located in the Mid-Atlantic (United States), Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula (including the parts: the Eastern Shore of Maryland / Eastern Shore of Virginia and the state of Delaware) with its mouth of the Bay at the south end located between Cape Henry and Cape Charles (headland), Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the Bay's drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) and all of District of Columbia. The Bay is approximately long from its northern headwaters in the Susquehanna River to its outlet in the Atlantic Ocea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Christie Tank
The Christie suspension is a suspension system developed by American engineer J. Walter Christie for his tank designs. It allowed considerably longer movement than conventional leaf spring systems then in common use, which allowed his tanks to have considerably greater cross-country speed. The system was first introduced on his M1928 design, and used on all of his designs until his death in 1944. History Christie advocated the use of lightweight tanks with long range and high speed, designed to penetrate enemy lines and attack their infrastructure and logistics capabilities. A major problem with tanks in World War I was tracked suspension failure. Christie's first tank design of 1919 could be driven on its wheels to get to the starting point and then the tracks fitted before it went into action. The US Tank Corps ordered a single tank from Christie's company based on this design. The tank, known as the M1919, was delivered in early 1921 and tested until Christie proposed ...

Landing Craft
Landing craft are small and medium seagoing watercraft, such as boats and barges, used to convey a landing force (infantry and vehicles) from the sea to the shore during an amphibious assault. The term excludes landing ships, which are larger. Production of landing craft peaked during World War II, with a significant number of different designs produced in large quantities by the United Kingdom and United States. Because of the need to run up onto a suitable beach, World War II landing craft were flat-bottomed, and many designs had a flat front, often with a lowerable ramp, rather than a normal bow. This made them difficult to control and very uncomfortable in rough seas. The control point (too rudimentary to call a bridge on LCA and similar craft) was normally at the extreme rear of the vessel, as were the engines. In all cases, they were known by an abbreviation derived from the official name rather than by the full title. History In the days of sail, the ship's boats were us ...

Special Service Squadron
The Special Service Squadron was a component of the United States Navy during the earlier part of the 20th century. The squadron patrolled the Caribbean Sea as an instrument of gunboat diplomacy. It was headquartered in Balboa, Panama Canal Zone. Records of the U.S. Atlantic Fleet have correspondence from the Special Service Squadron in 1907. The Special Service Squadron was stood up as a separate command from the fleet in 1920. Its purpose was to protect the Canal and American interests both in the Caribbean and on the Pacific coast of Central America (and it remained a separate command when the Atlantic and Pacific fleets were combined as the United States Fleet The United States Fleet was an organization in the United States Navy from 1922 until after World War II. The acronym CINCUS, pronounced "sink us", was used for Commander in Chief, United States Fleet. This was replaced by COMINCH in December 1941 ... in 1922).

Culebra Cut
The Culebra Cut, formerly called Gaillard Cut, is an artificial valley that cuts through the Continental Divide in Panama. The cut forms part of the Panama Canal, linking Gatun Lake, and thereby the Atlantic Ocean, to the Gulf of Panama and hence the Pacific Ocean. It is from the Pedro Miguel lock on the Pacific side to the Chagres River arm of Lake Gatun, with a water level above sea level. Construction of the cut was one of the great engineering feats of its time; the immense effort required to complete it was justified by the great significance of the canal to shipping, and in particular the strategic interests of the United States of America. ''Culebra'' is the name for the mountain ridge it cuts through, and was also originally applied to the cut itself. From 1915 to 2000 the cut was named ''Gaillard Cut'' after US Major David du Bose Gaillard, who had led the excavation. After the canal handover to Panama in 2000, the name was changed back to ''Culebra''. In Spanish the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Naval Academy
The United States Naval Academy (US Naval Academy, USNA, or Navy) is a federal service academy in Annapolis, Maryland. It was established on 10 October 1845 during the tenure of George Bancroft as Secretary of the Navy. The Naval Academy is the second oldest of the five U.S. service academies and it educates midshipmen for service in the officer corps of the United States Navy and United States Marine Corps. The campus is located on the former grounds of Fort Severn at the confluence of the Severn River and Chesapeake Bay in Anne Arundel County, east of Washington, D.C., and southeast of Baltimore. The entire campus, known colloquially as the Yard, is a National Historic Landmark and home to many historic sites, buildings, and monuments. It replaced Philadelphia Naval Asylum, in Philadelphia, that had served as the first United States Naval Academy from 1838 to 1845, when the Naval Academy formed in Annapolis.

USS California (BB-44)
USS ''California'' (BB-44) was the second of two s built for the United States Navy between her keel laying in October 1916 and her commissioning in August 1921. The ''Tennessee'' class was part of the standard series of twelve battleships built in the 1910s and 1920s, and were developments of the preceding . They were armed with a battery of twelve guns in four three-gun turrets. ''California'' served as the flagship of the Battle Fleet in the Pacific Ocean for the duration of her peacetime career. She spent the 1920s and 1930s participating in routine fleet training exercises, including the annual Fleet Problems, and cruises around the Americas and further abroad, such as a goodwill visit to Australia and New Zealand in 1925. ''California'' was moored in Pearl Harbor on 7 December 1941 when the Japanese attacked the port, bringing the United States into World War II. The ship was moderately damaged by a pair of torpedoes and a bomb, but a fire disabled the ship's electri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miraflores Locks
Miraflores is the name of one of the three locks that form part of the Panama Canal, and the name of the small lake that separates these locks from the Pedro Miguel Locks upstream. In the Miraflores locks, vessels are lifted (or lowered) in two stages, allowing them to transit to or from the Pacific Ocean port of Balboa in Panama City. Ships cross below the Bridge of the Americas, which connects North and South America South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southe .... As of 2005, the following schedule was in effect for ship transit through the locks: From 06:00 to 15:15, ships travel from the Pacific toward the Atlantic. From 15:45 to 23:00, ships travel from the Atlantic toward the Pacific. At any other time, travel is permitted in both directions. A visitors center allo ...

Gatun Locks
The Panama Canal locks ( es, Esclusas del Canal de Panamá) are a lock system that lifts ships up to the main elevation of the Panama Canal and down again. The original canal had a total of six steps (three up, three down) for a ship's passage. The total length of the lock structures, including the approach walls, is over . The locks were one of the greatest engineering works ever to be undertaken when they opened in 1914. No other concrete construction of comparable size was undertaken until the Hoover Dam, in the 1930s. There are two independent transit lanes, since each lock is built double. The size of the original locks limits the maximum size of ships that can transit the canal; this size is known as Panamax. Construction on the Panama Canal expansion project, which included a third set of locks, began in September 2007, finished by May 2016 and began commercial operation on 26 June 2016. The new locks allow transit of larger, New Panamax ships, which have a greater cargo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panama Canal Zone
The Panama Canal Zone ( es, Zona del Canal de Panamá), also simply known as the Canal Zone, was an unincorporated territory of the United States, located in the Isthmus of Panama, that existed from 1903 to 1979. It was located within the territory of Panama, consisting of the Panama Canal and an area generally extending on each side of the centerline, but excluding Panama City and Colón. Its capital was Balboa. The Panama Canal Zone was created on November 18, 1903 from the territory of Panama; established with the signing of the Hay–Bunau-Varilla Treaty, which allowed for the construction of the Panama Canal within the territory by the United States. The zone existed until October 1, 1979, when it was incorporated back into Panama. In 1904, the Isthmian Canal Convention was proclaimed. In it, the Republic of Panama granted to the United States in perpetuity the use, occupation, and control of a zone of land and land underwater for the construction, maintenance, opera ...
