USS Cordova
USS ''Cordova'' (CVE-39) (originally AVG-39 then later ACV-39) was an escort carrier launched 27 December 1942 by Seattle-Tacoma Shipbuilding of Tacoma, Washington; sponsored by Mrs. A. E. Mitchell. Reclassified CVE-39 on 15 July 1943, ''Cordova'' was transferred to the Royal Navy on 25 August 1943, as HMS ''Khedive'' (D62) ''Khedive'' served as the command ship for the South of France invasion in August 1944.former officers HMS ''Khedive'' From April to August 1945 was with the East Indies Fleet as part of the 21st Aircraft Carrier Squadron. ''Khedive'' was to take part in the invasion of Singapore in September 1945, codenamed Operation Tiderace. But with the Japanese surrender, she was merely deployed to the island for security. She was returned to United States custody on 26 January 1946 and sold into merchant service 23 January 1947 as ''Rempang'' (later ''Daphne''). She was sold for scrap in Spain in 1975.

Cordova Bay
Cordova Bay is a bay in the Alexander Archipelago of southeast Alaska. It opens onto Dixon Entrance to the south, between Cape Muzon on Dall Island and Point Marsh (a group of small islets just off Prince of Wales Island). The name Puerto Cordova y Cordova was given by the Spanish explorer Lieutenant Don Jacinto Caamaño in 1792, in honor of Admiral Luis de Córdova y Córdova. The name was published by George Vancouver in 1798. Cordova Bay is bordered on the west by Dall Island, Long Island, Tlevak Strait, and Sukkwan Island, and on the east by Prince of Wales Island. Cordova Bay extends north and west from its mouth to Lime Point, where it connects with Hetta Inlet. The Coast Survey lists the length as about from a point between the SE corner of Long Island and Dewey Rocks to Lime Point and an average width of about from Ship Islands to Lime Point. Hetta Inlet extends a further north, and then turns east for about . Gould Island almost closes the inlet shortly after it tur ...

Merchant Ship
A merchant ship, merchant vessel, trading vessel, or merchantman is a watercraft that transports cargo or carries passengers for hire. This is in contrast to pleasure craft, which are used for personal recreation, and naval ships, which are used for military purposes. They come in myriad sizes and shapes, from inflatable dive boats in Hawaii, to 5,000-passenger casino vessels on the Mississippi River, to tugboats plying New York Harbor, to oil tankers and container ships at major ports, to passenger-carrying submarines in the Caribbean. Many merchant ships operate under a "flag of convenience" from a country other than the home of the vessel's owners, such as Liberia and Panama, which have more favorable maritime laws than other countries. The Greek merchant marine is the largest in the world. Today, the Greek fleet accounts for some 16 per cent of the world's tonnage; this makes it currently the largest single international merchant fleet in the world, albeit not the la ...

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 ...

Grumman Avenger
The Grumman TBF Avenger (designated TBM for aircraft manufactured by General Motors) is an American World War II-era torpedo bomber developed initially for the United States Navy and Marine Corps, and eventually used by several air and naval aviation services around the world. The Avenger entered U.S. service in 1942, and first saw action during the Battle of Midway. Despite the loss of five of the six Avengers on its combat debut, it survived in service to become the most effective and widely-used torpedo bomber of World War II, sharing credit for sinking the super-battleships and (the only ships of that type sunk exclusively by American aircraft while under way) and being credited for sinking 30 submarines. Greatly modified after the war, it remained in use until the 1960s.Wheeler 1992, p. 53. Design and development The Douglas TBD Devastator, the U.S. Navy's main torpedo bomber introduced in 1935, was obsolescent by 1939. Bids were accepted from several companies, but Grum ...

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 ma ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hawker Hurricane Variants
The Hawker Hurricane was a British single-seat fighter aircraft designed and predominantly built by Hawker Aircraft Ltd. Some versions were built in Canada by the Canada Car and Foundry Co Ltd British variants Hurricane Mk I ; Hurricane Mk I (Early production) The first Mk I production machines were ready fairly quickly, with deliveries starting in December 1937. These early aircraft featured fabric-covered wings, and a wooden, two-bladed, fixed- pitch propeller. Initially the tailwheel was designed to be retractable; early on it was discovered that the Hurricane needed a larger rudder area to improve the control characteristics during a spin. To this end the lower part of the rudder was extended and a distinctive ventral "keel" was added to the rear fuselage. The tailwheel was now fixed. Early Hurricanes lacked armour or self-sealing tanks. They used "ring and bead" gunsights, with the ring being mounted above the instrument panel and the bead mounted on a post above the e ...

Vought F4U Corsair
The Vought F4U Corsair is an American fighter aircraft which saw service primarily in World War II and the Korean War. Designed and initially manufactured by Chance Vought, the Corsair was soon in great demand; additional production contracts were given to Goodyear, whose Corsairs were designated FG, and Brewster, designated F3A. The Corsair was designed and operated as a carrier-based aircraft, and entered service in large numbers with the U.S. Navy in late 1944 and early 1945. It quickly became one of the most capable carrier-based fighter-bombers of World War II. Some Japanese pilots regarded it as the most formidable American fighter of World War II and its naval aviators achieved an 11:1 kill ratio. Early problems with carrier landings and logistics led to it being eclipsed as the dominant carrier-based fighter by the Grumman F6F Hellcat, powered by the same Double Wasp engine first flown on the Corsair's initial prototype in 1940. Instead, the Corsair's early deployme ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Anti-aircraft Gun
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraf ...

Dual Purpose Gun
A dual-purpose gun is a naval artillery mounting designed to engage both surface and air targets. Description Second World War-era capital ships had four classes of artillery: the heavy main battery, intended to engage opposing battleships and cruisers of 305 mm to 457 mm (12 inch to 18 inch); a secondary battery for use against enemy destroyers of 152 mm to 203 mm (6 inch to 8 inch); heavy anti-aircraft guns of 76 mm to 127 mm (3 inch to 5 inch), which could create barrages to knock out airplanes at a distance; finally, light rapid-fire anti-aircraft batteries (A/A) to track and bring down aircraft at close range. The light A/A was dispersed throughout the ship and included both automatic cannons of 20 mm to 40 mm (.787 inch to 1.57 inch) and heavy machine guns of 12.7 mm to 14.5 mm (.50 inch to .58 inch). During World War II, the US Navy, Royal Navy, the French Navy, and the Imperial Japanese Navy combined the secondary battery with the heavy anti-aircraft guns, creating a d ...

Arresting Gear
An arresting gear, or arrestor gear, is a mechanical system used to rapidly decelerate an aircraft as it lands. Arresting gear on aircraft carriers is an essential component of naval aviation, and it is most commonly used on CATOBAR and STOBAR aircraft carriers. Similar systems are also found at land-based airfields for expeditionary or emergency use. Typical systems consist of several steel wire ropes laid across the aircraft landing area, designed to be caught by an aircraft's tailhook. During a normal arrestment, the tailhook engages the wire and the aircraft's kinetic energy is transferred to hydraulic damping systems attached below the carrier deck. There are other related systems which use nets to catch aircraft wings or landing gear. These ''barricade'' and ''barrier'' systems are only used for emergency arrestments for aircraft without operable tailhooks. History Arresting cable systems were invented by Hugh Robinson and were utilized by Eugene Ely on his first land ...

Aircraft Catapult
An aircraft catapult is a device used to allow aircraft to take off from a very limited amount of space, such as the deck of a vessel, but can also be installed on land-based runways in rare cases. It is now most commonly used on aircraft carriers, as a form of assisted take off. In the form used on aircraft carriers the catapult consists of a track, or slot, built into the flight deck, below which is a large piston or ''shuttle'' that is attached through the track to the nose gear of the aircraft, or in some cases a wire rope, called a catapult bridle, is attached to the aircraft and the catapult shuttle. Other forms have been used historically, such as mounting a launching cart holding a seaplane on a long girder-built structure mounted on the deck of a warship or merchant vessel, but most catapults share a similar sliding track concept. Different means have been used to propel the catapult, such as weight and derrick, gunpowder, flywheel, air pressure, hydraulic, and steam ...
