A3D Skywarrior
The Douglas A-3 Skywarrior is a jet-powered strategic bomber that was developed and produced by the Douglas Aircraft Company. It was designed by Douglas on behalf of the United States Navy, which sought a carrier-capable strategic bomber. During July 1949, Douglas was awarded the contract to produce its design, having bested eight other aircraft companies' submissions. Unlike rival designs, which had aimed for a maximum take-off weight, the Skywarrior was developed for a take-off weight, facilitating its use from the navy's existing s. Large portions of the aircraft were produced by the Westinghouse Electric Corporation, including its early Westinghouse J40 turbojet engines, which failed to meet promises and were replaced by the rival Pratt & Whitney J57 engine by mid-1953. On 28 October 1952, the prototype ''XA3D-1'' performed the type's maiden flight. On 31 March 1956, the Skywarrior entered squadron service with the Navy. Initially used in the nuclear-armed strategi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Whale
Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. As an informal and colloquial grouping, they correspond to large members of the infraorder Cetacea, i.e. all cetaceans apart from dolphins and porpoises. Dolphins and porpoises may be considered whales from a formal, cladistic perspective. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest non-cetacean living relatives are the hippopotamuses, from which they and other cetaceans diverged about 54 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have had their last common ancestor around 34 million years ago. Mysticetes include four extant (living) families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), and Eschrichtiidae (the grey whale). Odontocetes include the Monodontidae (beluga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas A-4 Skyhawk
The Douglas A-4 Skyhawk is a single-seat subsonic carrier-capable light attack aircraft developed for the United States Navy and United States Marine Corps in the early 1950s. The delta-winged, single turbojet engined Skyhawk was designed and produced by Douglas Aircraft Company, and later by McDonnell Douglas. It was originally designated A4D under the U.S. Navy's pre-1962 designation system. The Skyhawk is a relatively light aircraft, with a maximum takeoff weight of , and has a top speed of . The aircraft's five hardpoints support a variety of missiles, bombs, and other munitions. It is capable of carrying a bomb load equivalent to that of a World War II–era Boeing B-17 bomber, and can deliver nuclear weapons using a low-altitude bombing system and a "loft" delivery technique. The A-4 was originally powered by the Wright J65 turbojet engine; from the A-4E onwards, the Pratt & Whitney J52 engine was used. Skyhawks played key roles in the Vietnam War, the Yom Kippur ...

Ed Heinemann
Edward Henry Heinemann (March 14, 1908 – November 26, 1991) was a military aircraft designer for the Douglas Aircraft Company. Biography Heinemann was born in Saginaw, Michigan. He moved to California as a boy and was raised in Los Angeles. A self-taught engineer, he joined Douglas Aircraft as a draftsman in 1926, but was laid off within a year. After stints at International Aircraft, Moreland Aircraft, and the first Northrop Corporation, Heinemann rejoined Douglas after it acquired Northrop.

Supercarrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not successfully landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the role o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS United States (CVA-58)
USS ''United States'' (CVA-58) was to be the lead ship of a new design of aircraft carrier. On 29 July 1948, President Harry Truman approved construction of five "supercarriers", for which funds had been provided in the Naval Appropriations Act of 1949. The keel of the first of the five planned postwar carriers was laid down on 18 April 1949 at Newport News Drydock and Shipbuilding. The program was canceled in 1949, ''United States'' was not completed, and the other four planned carriers were never built. Design The chief proponent for the new large carrier was Admiral Marc Mitscher. He wanted a carrier that would be able to handle the most effective weapons of the day. Early design discussions centered around developing a carrier that would be able to support combat missions using the new jet aircraft. These were faster, larger and significantly heavier than the aircraft the - and -class carriers were handling at the end of the Second World War. It was thought that the aircr ...

Strategic Bombing
Strategic bombing is a military strategy used in total war with the goal of defeating the enemy by destroying its morale, its economic ability to produce and transport materiel to the theatres of military operations, or both. It is a systematically organized and executed attack from the air which can utilize strategic bombers, long- or medium-range missiles, or nuclear-armed fighter-bomber aircraft to attack targets deemed vital to the enemy's war-making capability. The term terror bombing is used to describe the strategic bombing of civilian targets without military value, in the hope of damaging an enemy's morale. One of the strategies of war is to demoralize the enemy so that peace or surrender becomes preferable to continuing the conflict. Strategic bombing has been used to this end. The phrase "terror bombing" entered the English lexicon towards the end of World War II and many strategic bombing campaigns and individual raids have been described as terror bombing by commen ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
