Flight Deck
The flight deck of an aircraft carrier is the surface from which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships". Flight decks have been in use upon ships since 1910, the American pilot Eugene Ely being the first individual to take off from a warship. Initially consisting of wooden ramps built over the forecastle of capital ships, a number of battlecruisers, including the British and , the American and , and the Japanese Akagi and battleship Kaga, were converted to aircraft carriers during the interwar period. The first aircraft carrier to feature a full-length flight deck, akin to the configuration of the modern vessels, was the converted liner . The armoured flight deck was another innovation pioneered by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stennis RudderSwing3
John Cornelius Stennis (August 3, 1901April 23, 1995) was an American politician who served as a U.S. Senator from the state of Mississippi. He was a Democrat who served in the Senate for over 41 years, becoming its most senior member for his last eight years. He retired from the Senate in 1989, and is, to date, the last Democrat to have been a U.S. Senator from Mississippi. Furthermore, at the time of his retirement, Stennis was the last United States Senator to have served during the presidency of Harry S. Truman. While attending law school, Stennis won a seat in the Mississippi House of Representatives, holding office from 1928 to 1932. After serving as a prosecutor and state judge, Stennis won a special election to fill the U.S. Senate vacancy following the death of Theodore G. Bilbo. He won election to a full term in 1952 and remained in the Senate until he declined to seek re-election in 1988. Stennis became the first Chairman of the Senate Ethics Committee and also ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Francisco Bay
San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the big cities of San Francisco, San Jose, and Oakland. San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Wetland of International Importance on February 2, 2017. Size The bay covers somewhere between , depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. The main part of the b ...

Naval Aviation
Naval aviation is the application of military air power by navies, whether from warships that embark aircraft, or land bases. Naval aviation is typically projected to a position nearer the target by way of an aircraft carrier. Carrier-based aircraft must be sturdy enough to withstand demanding carrier operations. They must be able to launch in a short distance and be sturdy and flexible enough to come to a sudden stop on a pitching flight deck; they typically have robust folding mechanisms that allow higher numbers of them to be stored in below-decks hangars and small spaces on flight decks. These aircraft are designed for many purposes, including air-to-air combat, surface attack, submarine attack, search and rescue, matériel transport, weather observation, reconnaissance and wide area command and control duties. Naval helicopters can be used for many of the same missions as fixed-wing aircraft while operating from aircraft carriers, helicopter carriers, destroyers and f ...

Colorado (Armored Cruiser 7), Renamed The Pueblo
Colorado (, other variants) is a state in the Mountain West subregion of the Western United States. It encompasses most of the Southern Rocky Mountains, as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is the eighth most extensive and 21st most populous U.S. state. The 2020 United States census enumerated the population of Colorado at 5,773,714, an increase of 14.80% since the 2010 United States census. The region has been inhabited by Native Americans and their ancestors for at least 13,500 years and possibly much longer. The eastern edge of the Rocky Mountains was a major migration route for early peoples who spread throughout the Americas. "''Colorado''" is the Spanish adjective meaning "ruddy", the color of the Fountain Formation outcroppings found up and down the Front Range of the Rocky Mountains. The Territory of Colorado was organized on February 28, 1861, and on August 1, 1876, U.S. President Ulyss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying Boat
A flying boat is a type of fixed-winged seaplane with a hull, allowing it to land on water. It differs from a floatplane in that a flying boat's fuselage is purpose-designed for floatation and contains a hull, while floatplanes rely on fuselage-mounted floats for buoyancy. Though the fuselage provides buoyancy, flying boats may also utilize under-wing floats or wing-like projections (called sponsons) extending from the fuselage for additional stability. Flying boats often lack landing gear which would allow them to land on the ground, though many modern designs are convertible amphibious aircraft which may switch between landing gear and flotation mode for water or ground takeoff and landing. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of the 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine Aircraft Carrier
A submarine aircraft carrier is a submarine equipped with aircraft for observation or attack missions. These submarines saw their most extensive use during World War II, although their operational significance remained rather small. The most famous of them were the Japanese s and the , although small numbers of similar craft were built for other nations' navies as well. Most operational submarine aircraft carriers, with the exception of the ''I-400'' and AM classes, used their aircraft for reconnaissance and observation. This is in contrast to the typical surface aircraft carrier, whose main function is serving as a base for offensive aircraft. Early history (World War I) Germany was the first nation to experiment with submarine aircraft carriers, initiated by the Imperial German Naval Air Service commander Oberleutnant zur See Friedrich von Arnauld de la Perière who commanded a unit of two Friedrichshafen FF.29 reconnaissance seaplanes in Zeebrugge. One of the first U-b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STOVL
A short take-off and vertical landing aircraft (STOVL aircraft) is a fixed-wing aircraft that is able to take off from a short runway (or take off vertically if it does not have a heavy payload) and land vertically (i.e. with no runway). The formal NATO definition (since 1991) is: On aircraft carriers, non-catapult-assisted, fixed-wing short takeoffs are accomplished with the use of thrust vectoring, which may also be used in conjunction with a runway "ski-jump". There are currently 14 aircraft carriers that operate these STOVL aircraft (United States United Kingdom Italy and Spain . Use of STOVL tends to allow aircraft to carry a larger payload compared to vertical take-off and landing (VTOL), while still only requiring a short runway. The most famous examples are the Hawker Siddeley Harrier and the Sea Harrier. Although technically VTOL aircraft, they are operationally STOVL aircraft due to the extra weight carried at take-off for fuel and armaments. The same is t ...

Ski-jump (aviation)
In aviation, a ski-jump is an upward-curved ramp that allows aircraft to take off from a runway that is shorter than the aircraft's required takeoff roll. By forcing the aircraft upwards, lift-off can be achieved at a lower airspeed than that required for sustained flight, while allowing the aircraft to accelerate to such speed in the air rather than on the runway. Ski-jumps are commonly used to launch airplanes from aircraft carriers that lack catapults. It is believed that the first use of the ski-jump occurred during the Second World War, where a temporary ramp was added to to assist the take-off of heavily laden Fairey Barracudas conducting a strike mission against the German battleship . During the Cold War era, the concept was studied as a means of reducing the length of flight decks required for future aircraft carriers as well as to facilitate ever-increasingly heavy aircraft at sea. The Royal Navy took a particular interest in the ski-jump during the 1970s, conducting a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jet Propulsion
Jet propulsion is the propulsion of an object in one direction, produced by ejecting a jet of fluid in the opposite direction. By Newton's third law, the moving body is propelled in the opposite direction to the jet. Reaction engines operating on the principle of jet propulsion include the jet engine used for aircraft propulsion, the pump-jet used for marine propulsion, and the rocket engine and plasma thruster used for spacecraft propulsion. Physics Jet propulsion is produced by some reaction engines or animals when thrust is generated by a fast moving jet of fluid in accordance with Newton's laws of motion. It is most effective when the Reynolds number is high—that is, the object being propelled is relatively large and passing through a low-viscosity medium. In animals, the most efficient jets are pulsed, rather than continuous, at least when the Reynolds number is greater than 6. Specific impulse Specific impulse (usually abbreviated ''I''sp) is a measure of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dennis Cambell
Rear Admiral Dennis Royle Farquharson Cambell, (13 November 1907 – 6 April 2000) was a flag officer of the Royal Navy, who invented the angled flight deck. Naval career Educated at Westminster School, Cambell was a Special Entry Cadet from 1925 in the training ship . From 15 September 1926, Cambell served as a midshipman on (in the Battle Cruiser Squadron of the Atlantic Fleet). Having been made acting sub-lieutenant at the start of 1929, he started lieutenants courses at the Royal Naval College, Greenwich, and continued from 12 August 1929 at Portsmouth. As sub-lieutenant he joined the destroyer, , Atlantic Fleet, on 23 March 1930. From September 1930 to the following August he was based at RAF Leuchars, having been made lieutenant in December 1930. Cambell left the course early to join 405 Flight (equipped with Fairey Flycatchers) in July 1931 at Hal Far (Malta) then to . In November 1932 they disembarked to RAF Netheravon.
