Strategic Nuclear Weapon
A strategic nuclear weapon (SNW) is a nuclear weapon that is designed to be used on targets often in settled territory far from the battlefield as part of a strategic plan, such as military bases, military command centers, arms industries, transportation, economic, and energy infrastructure, and countervalue targets such areas such as cities and towns. It is in contrast to a tactical nuclear weapon, which is designed for use in battle as part of an attack with and often near friendly conventional forces, possibly on contested friendly territory. As of , strategic nuclear weapons have been used twice in the 1945 United States bombings of Hiroshima and Nagasaki. Premise Strategic nuclear weapons generally have significantly larger yields, and typically starting from 100 kilotons up to destructive yields in the low megaton range for use especially in the enemy nation's interior far from friendly forces to maximize damage, especially to buried hard targets, like a missile s ...

Fat Man (replica Of Nuclear Bomb)
"Fat Man" (also known as Mark III) was the design of the nuclear weapon the United States used for seven of the first eight nuclear weapons ever detonated in history. It is also the most powerful design to ever be used in warfare. A Fat Man device was Atomic bombings of Hiroshima and Nagasaki#Bombing of Nagasaki, detonated over the Japanese city of Nagasaki on 9 August 1945. It was the second and largest of the only two nuclear weapons ever used in warfare. It was dropped from the Boeing B-29 Superfortress ''Bockscar'' piloted by Major Charles Sweeney. Its detonation marked the third nuclear explosion in history. The name Fat Man refers to the wide, round shape. Fat Man was an implosion-type nuclear weapon with a solid plutonium Nuclear reactor core, core, and later with improved cores. The first Fat Man to be detonated was the gadget in the Trinity (nuclear test), Trinity nuclear test less than a month earlier on 16 July at the Holloman Air Force Base, Alamogordo Bombing an ...

Atomic Bombings Of Hiroshima And Nagasaki
On 6 and 9 August 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki, respectively, during World War II. The aerial bombings killed between 150,000 and 246,000 people, most of whom were civilians, and remain the only uses of Nuclear warfare, nuclear weapons in an armed conflict. Surrender of Japan, Japan announced its surrender to the Allies on 15 August, six days after the bombing of Nagasaki and the Soviet–Japanese War, Soviet Union's declaration of war against Japan and Soviet invasion of Manchuria, invasion of Manchuria. The Japanese government signed an Japanese Instrument of Surrender, instrument of surrender on 2 September, End of World War II in Asia, ending the war. In the final year of World War II, the Allies of World War II, Allies prepared for a costly Operation Downfall, invasion of the Japanese mainland. This undertaking was preceded by a Air raids on Japan, conventional bombing and firebombing campaign that de ...

Soviet Union
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991. During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR. In practice, Government of the Soviet Union, its government and Economy of the Soviet Union, economy were Soviet-type economic planning, highly centralized. As a one-party state go ...

Massive Retaliation
Massive retaliation, also known as a massive response or massive deterrence, is a military doctrine and nuclear strategy in which a state commits itself to retaliate in much greater force in the event of an attack. It is associated with the U.S. national security policy of the Eisenhower administration during the early stages of the Cold War. Strategy In the event of an attack from an aggressor, a state would respond with force hugely disproportionate to the size of the attack, likely using nuclear weapons on a massive scale. The aim of massive retaliation is to deter another state from attacking first. For such a strategy to work, it must be made public knowledge to all possible aggressors, and they must believe that the state is willing and able to launch a second strike in the event of an attack. Massive retaliation works on the same principles as mutual assured destruction (MAD), with the important caveat that even a minor conventional attack on a nuclear state could c ...

John Foster Dulles
John Foster Dulles (February 25, 1888 – May 24, 1959) was an American politician, lawyer, and diplomat who served as United States secretary of state under President Dwight D. Eisenhower from 1953 until his resignation in 1959. A member of the Republican Party (United States), Republican Party, he was briefly a U.S. senator from New York in 1949. Dulles was a significant figure in the early Cold War era, who advocated an aggressive stance against communism throughout the world. Born in Washington, D.C., Dulles joined the leading New York law firm of Sullivan & Cromwell after graduating from George Washington University Law School. His grandfather, John W. Foster, and his uncle, Robert Lansing, both served as U.S. secretary of state, while his brother, Allen Dulles, served as the director of central intelligence from 1953 to 1961. Dulles served on the War Industries Board during World War I and he was a U.S. legal counsel at the 1919 Paris Peace Conference. He became a member of ...

US Secretary Of State
The United States secretary of state (SecState) is a member of the executive branch of the federal government of the United States and the head of the U.S. Department of State. The secretary of state serves as the principal advisor to the president of the United States on all foreign affairs matters. The secretary carries out the president's foreign policies through the U.S Department of State, which includes the Foreign Service, Civil Service, and U.S. Agency for International Development. The office holder is the second-highest-ranking member of the president's cabinet, after the vice president, and ranks fourth in the presidential line of succession; first amongst cabinet secretaries. Created in 1789 with Thomas Jefferson as its first office holder, the secretary of state represents the United States to foreign countries, and is therefore considered analogous to a secretary or minister of foreign affairs in other countries. The secretary of state is nominated by the pr ...

Eisenhower Administration
Dwight D. Eisenhower's tenure as the 34th president of the United States began with his first inauguration on January 20, 1953, and ended on January 20, 1961. Eisenhower, a Republican from Kansas, took office following his landslide victory over Democratic nominee Adlai Stevenson in the 1952 presidential election. Four years later, in the 1956 presidential election, he defeated Stevenson again, to win re-election in a larger landslide. Eisenhower was limited to two terms and was succeeded by Democrat John F. Kennedy, who won the 1960 presidential election. Eisenhower held office during the Cold War, a period of geopolitical tension between the United States and the Soviet Union. Eisenhower's New Look policy stressed the importance of nuclear weapons as a deterrent to military threats, and the United States built up a stockpile of nuclear weapons and nuclear weapons delivery systems during Eisenhower's presidency. Soon after taking office, Eisenhower negotiated an en ...

Nuclear Weapon Yield
The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated. It is usually expressed as a ''TNT equivalent'', the standardized equivalent mass of trinitrotoluene (TNT) which would produce the same energy discharge if detonated, either in kilotonnes (symbol kt, thousands of tonnes of TNT), in megatonnes (Mt, millions of tonnes of TNT). It is also sometimes expressed in terajoules (TJ); an explosive yield of one terajoule is equal to . Because the accuracy of any measurement of the energy released by TNT has always been problematic, the conventional definition is that one kilotonne of TNT is held simply to be equivalent to 1012 calories. The yield-to-weight ratio is the amount of weapon yield compared to the mass of the weapon. The practical maximum yield-to-weight ratio for fusion weapons (thermonuclear weapons) has been estimated to six megatonnes of TNT per tonne of bomb ...

Little Boy
Little Boy was a type of atomic bomb created by the Manhattan Project during World War II. The name is also often used to describe the specific bomb (L-11) used in the bombing of the Japanese city of Hiroshima by the Boeing B-29 Superfortress '' Enola Gay'' on 6 August 1945, making it the first nuclear weapon used in warfare, and the second nuclear explosion in history, after the Trinity nuclear test. It exploded with an energy of approximately and had an explosion radius of approximately which caused widespread death across the city. It was a gun-type fission weapon which used uranium that had been enriched in the isotope uranium-235 to power its explosive reaction. Little Boy was developed by Lieutenant Commander Francis Birch's group at the Los Alamos Laboratory. It was the successor to a plutonium-fueled gun-type fission design, Thin Man (nuclear bomb), Thin Man, which was abandoned in 1944 after technical difficulties were discovered. Little Boy used a charge of co ...

AGM-131 SRAM II
The AGM-131 SRAM II ("Short-Range Attack Missile") was a nuclear-tipped air-to-surface missile intended as a replacement for the AGM-69 SRAM. The solid-fueled missile was to be dropped from a B-1B Lancer, carry the W89 warhead and have a range of 400 km. However, the program was cancelled by President George H. W. Bush for geopolitical reasons just as the first flight-test missile was delivered. Development The mission of the SRAM family is to deliver the warhead to the target without the need for the penetrating bomber to directly overfly the target. The SRAM family of weapons had an extremely small radar signature and were near-impossible to counter. SRAM ensured the airborne leg of the US nuclear triad (the others being land-based ICBMs and SLBM) and was the penetrating air launched strategic nuclear weapon for the B-1 Lancer and B-2 Spirit. In 1977, the USAF planned to develop an upgrade of the SRAM for the forthcoming B-1A bomber as AGM-69B SRAM B. When the B-1A was ...

Strategic Bomber
A strategic bomber is a medium- to long-range Penetrator (aircraft), penetration bomber aircraft designed to drop large amounts of air-to-ground weaponry onto a distant target for the purposes of debilitating the enemy's capacity to wage war. Unlike tactical bombing, tactical bombers, Penetrator (aircraft), penetrators, fighter-bombers, and attack aircraft, which are used in air interdiction operations to attack enemy combatants and military equipment, strategic bombers are designed to fly into enemy territory to destroy strategic targets (e.g., infrastructure, logistics, Military base, military installations, factories, etc.). In addition to strategic bombing, strategic bombers can be used for tactical bombing, tactical missions. There are currently only three countries that operate strategic bombers: the United States, Russia and China. The modern strategic bomber role appeared after Strategic bombing during World War II, strategic bombing was widely employed, and Atomic bombing ...
