108-408: The Raytheon MGM-157 EFOGM ( Enhanced Fiber Optic Guided Missile ) was a long-range enhanced fiber optic guided missile developed for the U.S. Army during the 1980s and 1990s to test the use of fiber optics in missiles. The missile was launched vertically and manually controlled by an operator on the ground by use of a television camera mounted on the nose. The signals from the camera were carried via

216-613: A fuel and oxidizer mixed in select proportions with the grain size and burn chamber determining the rate and time of burn. Larger missiles might use liquid-propellant rockets where propulsion is provided by a single or combination of liquid fuels. A hybrid system uses solid rocket fuel with a liquid oxidizer. Jet engines are generally used in cruise missiles , most commonly of the turbojet type, because of their relative simplicity and low frontal area while turbofans and ramjets can also be theoretically used. Long-range missiles have multiple engine stages and might use similar type or

324-440: A show of force . ASATs have also been used to remove decommissioned satellites. ASAT roles include defensive measures against an adversary's space-based and nuclear weapons, a force multiplier for a nuclear first strike , a countermeasure against an adversary's anti-ballistic missile defense (ABM), an asymmetric counter to a technologically superior adversary, and a counter-value weapon. Cold War The Cold War

432-804: A German rebuilding effort set forth by western European countries in 1948, the US, Britain and France spearheaded the establishment of the Federal Republic of Germany from the three Western zones of occupation in April 1949. The Soviet Union proclaimed its zone of occupation in Germany the German Democratic Republic that October. Media in the Eastern Bloc was an organ of the state , completely reliant on and subservient to

540-423: A ballistic trajectory. Most anti-tank and anti-ship missiles are part of surface-to-surface missile systems. An anti-satellite weapon (ASAT) is a space weapon designed to incapacitate or destroy satellites for strategic or tactical purposes. Although no ASAT system has yet been utilized in warfare , a few countries have successfully shot down their own satellites to demonstrate their ASAT capabilities in

648-646: A general term, in his essay "You and the Atomic Bomb", published 19 October 1945 in the British newspaper Tribune . Contemplating a world living in the shadow of the threat of nuclear warfare , Orwell looked at James Burnham 's predictions of a polarized world, writing: Looking at the world as a whole, the drift for many decades has been not towards anarchy but towards the reimposition of slavery... James Burnham's theory has been much discussed, but few people have yet considered its ideological implications—that is,

756-675: A higher standoff distance engaging targets from far away and out of range of low range air defenses. A surface-to-air missile (SAM) is a missile designed to be launched from the ground to destroy aircraft , other missiles or flying objects. It is a type of anti-aircraft system and missiles have replaced most other forms of anti-aircraft weapons due to the increased range and accuracy. Anti-aircraft guns are being used only for specialized close-in firing roles. Missiles can be mounted in clusters on vehicles or towed on trailers and can be hand operated by infantry. SAMs frequently use solid-propellants and may be guided by radar or infrared sensors or by

864-689: A human operator may operate it manually or a support or launch system will transmit commands by using either optic fiber or radio to guide the missile. The flight system uses the data from the targeting or guidance system to maneuver the missile in flight which might be accomplished using vectored thrust of engines or aerodynamic maneuvering using flight control surfaces such as wings , fins and canards . Missiles are powered by propellants igniting to produce thrust and might employ types of rocket or jet engines . Rockets might be fueled by solid-propellants which are comparatively easier to maintain and enables faster deployment. These propellants contain

972-565: A human operator using optical tracking. A surface-to-surface missile (SSM) is a missile designed to be launched from the ground or the sea and strike targets on land. They may be fired from hand-held or vehicle mounted devices, from fixed installations or from a ship. They are often powered by a rocket engine or sometimes fired by an explosive charge, since the launching platform is typically stationary or moving slowly. They usually have fins and/or wings for lift and stability, although hyper-velocity or short-ranged missiles may use body lift or fly

1080-415: A limited strike in a smaller area and might carry conventional or nuclear warheads. Strategic missiles are long-range weapons used to target beyond the immediate vicinity and are mostly designed to carry nuclear warheads though other warheads can also be fitted. Strategic weapons are often classified into cruise and ballistic missiles . Ballistic missiles are powered by rockets during launch and follow

1188-522: A major propaganda effort began in 1949 was Radio Free Europe/Radio Liberty , dedicated to bringing about the peaceful demise of the communist system in the Eastern Bloc. Radio Free Europe attempted to achieve these goals by serving as a surrogate home radio station, an alternative to the controlled and party-dominated domestic press in the Soviet Bloc. Radio Free Europe was a product of some of

1296-437: A mix of engine types. Some missiles may have additional propulsion from another source at launch such as a catapult , cannon or tank gun . Missiles have one or more explosive warheads , although other weapon types may also be used. The warheads of a missile provide its primary destructive power which might cause secondary destruction due to the kinetic energy of the weapon and unused fuel. Warheads are most commonly of

1404-642: A neutral Germany to prevent West Germany's incorporation into NATO, but his attempts were cut short after he was executed several months later during a Soviet power struggle. The events led to the establishment of the Bundeswehr , the West German military, in 1955. In 1949, CCP Chairman Mao Zedong 's People's Liberation Army defeated Chiang Kai-shek 's United States-backed Kuomintang (KMT) Nationalist Government in China. The KMT-controlled territory

1512-675: A new war". On 6 September 1946, James F. Byrnes delivered a speech in Germany repudiating the Morgenthau Plan (a proposal to partition and de-industrialize post-war Germany) and warning the Soviets that the US intended to maintain a military presence in Europe indefinitely. As Byrnes stated a month later, "The nub of our program was to win the German people ... it was a battle between us and Russia over minds ..." In December,

1620-710: A plan envisioning an economically self-sufficient Germany, including a detailed accounting of the industrial plants, goods and infrastructure already taken by the Soviets. In June 1947, in accordance with the Truman Doctrine , the United States enacted the Marshall Plan , a pledge of economic assistance for all European countries willing to participate, including the Soviet Union. Under the plan, which President Harry S. Truman signed on 3 April 1948,

1728-629: A secret 1950 document, the National Security Council proposed reinforcing pro-Western alliance systems and quadrupling spending on defense. Truman, under the influence of advisor Paul Nitze , saw containment as implying complete rollback of Soviet influence in all its forms. United States officials moved to expand this version of containment into Asia , Africa , and Latin America , in order to counter revolutionary nationalist movements, often led by communist parties financed by

1836-409: A single soldier, to larger tripod-mounted or vehicle and aircraft mounted missile systems. Earlier man-portable anti-tank weapons like anti-tank rifles and magnetic anti-tank mines had a short range but sophisticated antitank missiles can be directed to a longer target by several different guidance systems, including laser guiding, television camera, or wire guiding . An air-to-air missile (AAM)

1944-480: A source of intelligence. During the late 1970s and 1980s, the KGB perfected its use of espionage to sway and distort diplomacy. Active measures were "clandestine operations designed to further Soviet foreign policy goals," consisting of disinformation, forgeries, leaks to foreign media, and the channeling of aid to militant groups. Retired KGB Major General Oleg Kalugin , former head of Foreign Counter Intelligence for

2052-468: A thin wire that unspooled the further up the missile reached. The weapon was primarily designed for anti-tank use, or against low flying helicopters. This article relating to missiles is a stub . You can help Misplaced Pages by expanding it . Missile A missile is an airborne ranged weapon capable of self-propelled flight aided usually by a propellant , jet engine or rocket motor . Historically, 'missile' referred to any projectile that

2160-555: A time. In 1979, the toppling of pro-US governments in Iran and Nicaragua and a Soviet invasion of Afghanistan again raised fears of war. In the 1980s, the US provided support for anti-communist forces in Africa, Asia, and Latin America, and the leadership of the USSR changed with the rise of Mikhail Gorbachev , who expanded political freedoms in his country and the Eastern Bloc. This led to

2268-516: A trajectory that arches upwards before descending to reach its intended target while cruise missiles are continuously powered by jet engines and travel at a flatter trajectory. A ballistic missile is powered by single or multiple rockets in stages initially before following an unpowered trajectory that arches upwards before descending to reach its intended target. It can carry both nuclear and conventional warheads. A ballistic missile might reach supersonic or hypersonic speed and often travel out of

2376-542: A unified and neutral Germany was undesirable, with Walter Bedell Smith telling General Eisenhower "in spite of our announced position, we really do not want nor intend to accept German unification on any terms that the Russians might agree to, even though they seem to meet most of our requirements." Shortly thereafter, Stalin instituted the Berlin Blockade (June 1948 – May 1949), one of the first major crises of

2484-399: Is a standoff anti-submarine weapon variant of anti-ship missiles used to deliver an explosive warhead aimed directly at a submarine , a depth charge , or a homing torpedo . An anti-tank guided missile (ATGM) is a guided missile primarily designed to hit and destroy heavily armored military vehicles . ATGMs range in size from shoulder-launched weapons, which can be transported by

2592-591: Is a critical factor for its effectiveness. The missile guidance system accomplishes this by four steps: tracking the target, computing the directions using tracking information, directing the computed inputs to steering control and steering the missile by directing inputs to motors or flight control surfaces. The guidance system consists of three sections: launch, mid-course and terminal with same or different systems employed across sections. The guidance and homing systems are generally classified broadly into active , semi-active and passive . In active homing systems,

2700-523: Is a missile fired from a fighter aircraft for the purpose of destroying another aircraft. AAMs are typically powered by one or more rocket motors , usually solid fueled but sometimes liquid fueled . A radar or heat emission based homing system is generally used and sometimes can use a combination. Short range missiles used to engage opposing aircraft at ranges of less than 16 km often use infrared guidance while long range missiles mostly rely upon radar guidance. An air-to-surface missile (ASM)

2808-496: Is a missile fired from an attack aircraft , strike fighter or an attack helicopter for the purpose of destroying land based targets. Missiles are typically guided and unguided glide bombs not considered missiles. The most common propulsion systems are rocket motor for short range and jet engines for long-range but ramjets are also used. Missile guidance is typically via laser , infrared homing, optical or satellite . Air-to-surface missiles for ground attack by aircraft provide

2916-571: Is often self-guided. It flies at lower speeds (often subsonic or supersonic ) and close to the surface of the Earth, which expends more fuel but makes it difficult to detect. Missiles might be also be classified basis launch platform and target into surface-to-air , surface-to-surface , air-to-air , air-to-surface , anti-ship and anti-tank . An anti-ship missile (AShM) is designed for use against large boats and ships such as destroyers and aircraft carriers . Most anti-ship missiles are of

3024-762: Is thrown, shot or propelled towards a target; this usage is still recognized today with any unguided jet- or rocket-propelled weapons generally described as rocket artillery . Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Missiles are also generally guided towards specific targets termed as guided missiles or guided rockets . Missile systems usually have five system components: targeting , guidance system , flight system, engine , and warhead . Missiles are primarily classified into different types based on firing source and target such as surface-to-surface , air-to-surface , surface-to-air and air-to-air missiles . Rockets were

3132-513: The Baltic to Trieste in the Adriatic ". A week later, on 13 March, Stalin responded vigorously to the speech, saying Churchill could be compared to Adolf Hitler insofar as he advocated the racial superiority of English-speaking nations so that they could satisfy their hunger for world domination, and that such a declaration was "a call for war on the USSR." The Soviet leader also dismissed

3240-859: The Berlin Wall to prevent the citizens of East Berlin from fleeing to West Berlin , at the time part of United States-allied West Germany . Major crises of this phase included the Berlin Blockade of 1948–1949, the Chinese Communist Revolution of 1945–1949, the Korean War of 1950–1953, the Hungarian Revolution of 1956 and the Suez Crisis of that same year, the Berlin Crisis of 1961 ,

3348-758: The Cuban Missile Crisis began after deployments of U.S. missiles in Europe and Soviet missiles in Cuba; it is widely considered the closest the Cold War came to escalating into full-scale nuclear war . Another major proxy conflict was the Vietnam War of 1955 to 1975; the Soviets solidified their domination of Eastern Europe with operations such as the Warsaw Pact invasion of Czechoslovakia in 1968. Both powers used economic aid in an attempt to win

3456-719: The Cuban Missile Crisis of 1962, and the Vietnam War of 1964–1975. Both superpowers competed for influence in Latin America and the Middle East , and the decolonising states of Africa , Asia , and Oceania . Following the Cuban Missile Crisis, this phase of the Cold War saw the Sino-Soviet split . Between China and the Soviet Union's complicated relations within the Communist sphere, leading to

3564-505: The Earth's atmosphere before re-entry. It usually has three stages of flight: Ballistic missiles are categorized based on range as: A cruise missile is a guided missile that remains in the atmosphere and flies the major portion of its flight at a constant speed. It is designed to deliver a large warhead over long distances with high precision and are propelled by jet engines. A cruise missile can be launched from multiple platforms and

3672-847: The Eastern Bloc . Cominform faced an embarrassing setback the following June, when the Tito–Stalin split obliged its members to expel Yugoslavia, which remained communist but adopted a non-aligned position and began accepting financial aid from the US. Besides Berlin, the status of the city of Trieste was at issue. Until the break between Tito and Stalin, the Western powers and the Eastern bloc faced each other uncompromisingly. In addition to capitalism and communism, Italians and Slovenes, monarchists and republicans as well as war winners and losers often faced each other irreconcilably. The neutral buffer state Free Territory of Trieste , founded in 1947 with

3780-511: The KGB and involved in its intelligence operations, adhered to Moscow's line, although dissent began to appear after 1956. Other critiques of the consensus policy came from anti-Vietnam War activists , the Campaign for Nuclear Disarmament , and the anti-nuclear movement . In early 1947, France, Britain and the United States unsuccessfully attempted to reach an agreement with the Soviet Union for

3888-518: The Kingdom of Greece in its civil war against Communist-led insurgents. In the same month, Stalin conducted the rigged 1947 Polish legislative election which constituted an open breach of the Yalta Agreement . The US government responded to this announcement by adopting a policy of containment , with the goal of stopping the spread of communism . Truman delivered a speech calling for

3996-551: The Napoleonic Wars . In the early 20th century, American Robert Goddard and German Hermann Oberth developed early rockets propelled by jet engines. In the 1920s, Soviet Union developed solid fuel rockets at the Gas Dynamics Laboratory . Later, the first missiles to be used operationally were a series of rocket based missiles developed by Nazi Germany during World War II including

4104-569: The Sino-Soviet border conflict , while France, a Western Bloc state, began to demand greater autonomy of action. The Warsaw Pact invasion of Czechoslovakia occurred to suppress the Prague Spring of 1968, while the United States experienced internal turmoil from the civil rights movement and opposition to United States involvement in the Vietnam War . In the 1960s–1970s, an international peace movement took root among citizens around

4212-746: The Soviet boycott of the Allied Control Council and its incapacitation, an event marking the beginning of the full-blown Cold War and the end of its prelude, as well as ending any hopes at the time for a single German government and leading to formation in 1949 of the Federal Republic of Germany and German Democratic Republic . The twin policies of the Truman Doctrine and the Marshall Plan led to billions in economic and military aid for Western Europe, Greece, and Turkey. With

4320-608: The Space Race . The US and USSR were both part of the Allies of World War II , the military coalition which had defeated Nazi Germany and Imperial Japan in 1945. After the war, the USSR installed satellite governments in the territories of Eastern and Central Europe it had occupied, and promoted the spread of communism to North Korea in 1948 and created an alliance with the People's Republic of China in 1949. The US declared

4428-568: The Truman Doctrine of " containment " in 1947, launched the Marshall Plan in 1948 to assist Western Europe's economic recovery, and founded the NATO military alliance in 1949 (which was matched by the Soviet-led Warsaw Pact in 1955). Germany's split occupation zones solidified into East and West Germany in 1949. The first major proxy war of the period was the Korean War from 1950 to 1953, which ended in stalemate. In 1962,

4536-609: The Turkish Straits crisis and Black Sea border disputes were also a major factor in increasing tensions. In September, the Soviet side produced the Novikov telegram, sent by the Soviet ambassador to the US but commissioned and "co-authored" by Vyacheslav Molotov ; it portrayed the US as being in the grip of monopoly capitalists who were building up military capability "to prepare the conditions for winning world supremacy in

4644-515: The United Nations Security Council Resolution 82 and 83 backed the defense of South Korea, although the Soviets were then boycotting meetings in protest of the fact that Taiwan (Republic of China), not the People's Republic of China , held a permanent seat on the council. A UN force of sixteen countries faced North Korea, although 40 percent of troops were South Korean, and about 50 percent were from

4752-518: The V-1 flying bomb and V-2 rocket which used mechanical autopilot to keep the missile flying along a pre-chosen route. Less well known were a series of anti-ship and anti-aircraft missiles, typically based on a simple radio control ( command guidance ) system directed by the operator. However, these early systems in World War ;II were only built in small numbers. After World War II,

4860-540: The high explosive type, often employing shaped charges to exploit the accuracy of a guided weapon to destroy hardened targets. Warhead might carry conventional , incendiary , nuclear , chemical , biological or radiological weapons . Missiles can be classified into categories by various parameters such as type, launch platform and target, range, propulsion and guidance system. Missiles are generally categorized into strategic or tactical missile systems. Tactical missile systems are short-range systems used to carry out

4968-561: The sea skimming variety, and many use a combination of inertial guidance and active radar homing . A large number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. Many anti-ship missiles can be launched from a variety of weapons systems including surface warships , submarines , fighter aircraft , maritime patrol aircraft , helicopters , shore batteries , land vehicles and by infantry . Anti-submarine missile

5076-463: The Cold War was in its essence a war of ideas. The United States, acting through the CIA, funded a long list of projects to counter the communist appeal among intellectuals in Europe and the developing world. The CIA also covertly sponsored a domestic propaganda campaign called Crusade for Freedom . The rearmament of West Germany was achieved in the early 1950s. Its main promoter was Konrad Adenauer ,

5184-465: The Cold War, preventing Western food, materials and supplies from arriving in the West Germany's exclave of West Berlin . The United States (primarily), Britain, France, Canada, Australia, New Zealand, and several other countries began the massive "Berlin airlift", supplying West Berlin with food and other provisions despite Soviet threats. The Soviets mounted a public relations campaign against

5292-777: The Communist governments militarily. The fall of the Iron Curtain after the Pan-European Picnic and the Revolutions of 1989 , which represented a peaceful revolutionary wave with the exception of the Romanian revolution and the Afghan Civil War (1989–1992) , overthrew almost all of the Marxist–Leninist regimes of the Eastern Bloc. The Communist Party of the Soviet Union itself lost control in

5400-400: The KGB (1973–1979), described active measures as "the heart and soul of Soviet intelligence ." During the Sino-Soviet split , "spy wars" also occurred between the USSR and PRC. In September 1947, the Soviets created Cominform to impose orthodoxy within the international communist movement and tighten political control over Soviet satellites through coordination of communist parties in

5508-428: The Marshall Plan, seeing it as an effort by the US to impose its influence on Europe. In response, the Soviet Union established Comecon (Council for Mutual Economic Assistance) to foster economic cooperation among communist states. The United States and its Western European allies sought to strengthen their bonds and used the policy of containment against Soviet influence; they accomplished this most notably through

SECTION 50

5616-514: The Russian Civil War further complicated relations, and although the Soviet Union later allied with Western powers to defeat Nazi Germany , this cooperation was strained by mutual suspicions. In the immediate aftermath of World War II, disagreements about the future of Europe, particularly Eastern Europe , became central. The Soviet Union's establishment of communist regimes in the countries it had liberated from Nazi control—enforced by

5724-481: The Soviet Union and its communist party , which had an influence across the Second World and was also tied to a network of authoritarian states. The Soviet Union had a command economy and installed similarly communist regimes its in satellites. United States involvement in regime change during the Cold War included support for anti-communist and right-wing dictatorships , governments, and uprisings across

5832-467: The Soviet Union was used to monitor dissent from official Soviet politics and morals. Although to an extent disinformation had always existed, the term itself was invented, and the strategy formalized by a black propaganda department of the Soviet KGB. Based on the amount of top-secret Cold War archival information that has been released, historian Raymond L. Garthoff concludes there probably

5940-572: The Soviet Union, which at the time was undergoing the Era of Stagnation . This phase saw the new Soviet leader Mikhail Gorbachev introducing the liberalizing reforms of glasnost ("openness") and perestroika ("reorganization") and ending Soviet involvement in Afghanistan in 1989. Pressures for national sovereignty grew stronger in Eastern Europe, and Gorbachev refused to further support

6048-558: The Soviet Union. A number of self-proclaimed Marxist–Leninist governments were formed in the second half of the 1970s in developing countries , including Angola , Mozambique , Ethiopia , Cambodia , Afghanistan , and Nicaragua . Détente collapsed at the end of the decade with the beginning of the Soviet–Afghan War in 1979. Beginning in the 1980s, this phase was another period of elevated tension. The Reagan Doctrine led to increased diplomatic, military, and economic pressures on

6156-643: The Soviets accumulated after broken promises by Stalin and Molotov concerning Europe and Iran. Following the World War II Anglo-Soviet invasion of Iran , the country was occupied by the Red Army in the far north and the British in the south. Iran was used by the United States and British to supply the Soviet Union, and the Allies agreed to withdraw from Iran within six months after the cessation of hostilities. However, when this deadline came,

6264-535: The Soviets agreed to withdraw from Iran after persistent US pressure, an early success of containment policy. By 1947, US president Harry S. Truman was outraged by the perceived resistance of the Soviet Union to American demands in Iran, Turkey, and Greece, as well as Soviet rejection of the Baruch Plan on nuclear weapons. In February 1947, the British government announced that it could no longer afford to finance

6372-559: The Soviets had permitted to retain democratic structures. The public brutality of the coup shocked Western powers more than any event up to that point, set in motion a brief scare that war would occur, and swept away the last vestiges of opposition to the Marshall Plan in the United States Congress. In an immediate aftermath of the crisis, the London Six-Power Conference was held, resulting in

6480-545: The Soviets remained in Iran under the guise of the Azerbaijan People's Government and Kurdish Republic of Mahabad . Shortly thereafter, on 5 March, former British prime minister Winston Churchill delivered his famous " Iron Curtain " speech in Fulton, Missouri . The speech called for an Anglo-American alliance against the Soviets, whom he accused of establishing an "iron curtain" dividing Europe from " Stettin in

6588-455: The Truman Doctrine marked the beginning of a US bipartisan defense and foreign policy consensus between Republicans and Democrats focused on containment and deterrence that weakened during and after the Vietnam War , but ultimately persisted thereafter. Moderate and conservative parties in Europe, as well as social democrats, gave virtually unconditional support to the Western alliance, while European and American Communists , financed by

Under the leadership of Alcide De Gasperi the Italian Christian Democrats defeated the powerful Communist – Socialist alliance in the elections of 1948 . All major powers engaged in espionage, using a great variety of spies, double agents , moles , and new technologies such as the tapping of telephone cables. The Soviet KGB ("Committee for State Security"),

6804-476: The US government gave to Western European countries over $ 13 billion (equivalent to $ 189 billion in 2016) to rebuild the economy of Europe . Later, the program led to the creation of the OECD . The plan's aim was to rebuild the democratic and economic systems of Europe and to counter perceived threats to the European balance of power , such as communist parties seizing control through revolutions or elections. The plan also stated that European prosperity

6912-419: The US was trying to buy a pro-US re-alignment of Europe. Stalin therefore prevented Eastern Bloc nations from receiving Marshall Plan aid. The Soviet Union's alternative to the Marshall Plan, which was purported to involve Soviet subsidies and trade with central and eastern Europe, became known as the Molotov Plan (later institutionalized in January 1949 as the Council for Mutual Economic Assistance ). Stalin

7020-424: The USSR. In this way, this US would exercise " preponderant power ," oppose neutrality, and establish global hegemony . In the early 1950s (a period sometimes known as the " Pactomania "), the US formalized a series of alliances with Japan (a former WWII enemy), South Korea , Taiwan , Australia , New Zealand , Thailand and the Philippines (notably ANZUS in 1951 and SEATO in 1954), thereby guaranteeing

7128-412: The United Nations, was split up and dissolved in 1954 and 1975, also because of the détente between the West and Tito. The US and Britain merged their western German occupation zones into " Bizone " (1 January 1947, later "Trizone" with the addition of France's zone, April 1949). As part of the economic rebuilding of Germany, in early 1948, representatives of a number of Western European governments and

7236-445: The United States a number of long-term military bases. One of the more significant examples of the implementation of containment was the United Nations US-led intervention in the Korean War . In June 1950, after years of mutual hostilities, Kim Il Sung 's North Korean People's Army invaded South Korea at the 38th parallel . Stalin had been reluctant to support the invasion but ultimately sent advisers. To Stalin's surprise,

7344-401: The United States announced an agreement for a merger of western German areas into a federal governmental system. In addition, in accordance with the Marshall Plan , they began to re-industrialize and rebuild the West German economy, including the introduction of a new Deutsche Mark currency to replace the old Reichsmark currency that the Soviets had debased. The US had secretly decided that

7452-450: The Warsaw Pact's primary function was to safeguard Soviet hegemony over its Eastern European satellites, with the pact's only direct military actions having been the invasions of its own member states to keep them from breaking away; in the 1960s, the pact evolved into a multilateral alliance, in which the non-Soviet Warsaw Pact members gained significant scope to pursue their own interests. In 1961, Soviet-allied East Germany constructed

7560-423: The Western agencies paid special attention to debriefing Eastern Bloc defectors . Edward Jay Epstein describes that the CIA understood that the KGB used "provocations", or fake defections, as a trick to embarrass Western intelligence and establish Soviet double agents. As a result, from 1959 to 1973, the CIA required that East Bloc defectors went through a counterintelligence investigation before being recruited as

He argued that there was nothing surprising in "the fact that the Soviet Union, anxious for its future safety, [was] trying to see to it that governments loyal in their attitude to the Soviet Union should exist in these countries." Soviet territorial demands to Turkey regarding the Dardanelles in

7776-1021: The advent of the Cold War and development of nuclear weapons necessitated faster, accurate and versatile missiles with longer range and missile development was pursued by multiple countries. Various attempts have been made to control the spread of long range missiles capable of carrying weapons of mass destruction , such as the Missile Technology Control Regime (1987) and the International Code of Conduct against Ballistic Missile Proliferation (2002). These were voluntary and not international treaties . Though not legally binding, more than 140 countries have been part of these agreements, and provide prior information on missile programs, expected launches, and tests. The gradual introduction of missile launched hypersonic glide vehicles since 2019, anti-satellite missiles , and

7884-613: The allocation of $ 400 million to intervene in the war and unveiled the Truman Doctrine , which framed the conflict as a contest between free peoples and totalitarian regimes. American policymakers accused the Soviet Union of conspiring against the Greek royalists in an effort to expand Soviet influence even though Stalin had told the Communist Party to cooperate with the British-backed government. Enunciation of

The most famous Soviet operation involved its atomic spies that delivered crucial information from the United States' Manhattan Project , leading the USSR to detonate its first nuclear weapon in 1949, four years after the American detonation and much sooner than expected. A massive network of informants throughout

8100-716: The chancellor of West Germany, with France the main opponent. Washington had the decisive voice. It was strongly supported by the Pentagon (the US military leadership), and weakly opposed by President Truman; the State Department was ambivalent. The outbreak of the Korean War in June 1950 changed the calculations and Washington now gave full support. That also involved naming Dwight D. Eisenhower in charge of NATO forces and sending more American troops to West Germany. There

8208-515: The communist party. Radio and television organizations were state-owned, while print media was usually owned by political organizations, mostly by the local communist party. Soviet radio broadcasts used Marxist rhetoric to attack capitalism, emphasizing themes of labor exploitation, imperialism and war-mongering. Along with the broadcasts of the BBC and the Voice of America to Central and Eastern Europe,

8316-497: The country and was banned following the 1991 Soviet coup attempt that August. This in turn led to the formal dissolution of the Soviet Union in December 1991 and the collapse of Communist governments across much of Africa and Asia. The Russian Federation became the Soviet Union's successor state, while many of the other republics emerged from the Soviet Union's collapse as fully independent post-Soviet states . The United States

8424-426: The deployment of dual use missiles capable of carrying both conventional and nuclear warheads are proliferation concerns. A missile is most often guided by a guidance system though there are missiles that are unguided during some phases of flight. Missile guidance refers to methods of guiding a missile to its intended target. Effective guidance is important because reaching the target position accurately and precisely

8532-463: The fall of the communist governments of Europe from 1989, which concluded with the fall of the Soviet Union in 1991. The Western Bloc included the US and a number of First World nations that were generally capitalist and liberal democratic but tied to a network of often authoritarian Third World states, most of which were the European powers' former colonies . The Eastern Bloc was led by

8640-401: The formation of NATO , which was essentially a defensive agreement in 1949. The Soviet Union countered with the Warsaw Pact in 1955, which had similar results with the Eastern Bloc. As by that time the Soviet Union already had an armed presence and political domination all over its eastern satellite states, the pact has been long considered superfluous. Although nominally a defensive alliance,

8748-529: The kind of world-view, the kind of beliefs, and the social structure that would probably prevail in a state which was at once unconquerable and in a permanent state of "cold war" with its neighbours. In The Observer of 10 March 1946, Orwell wrote, "...after the Moscow conference last December, Russia began to make a 'cold war' on Britain and the British Empire." The first use of the term to describe

8856-402: The loyalty of non-aligned countries , such as India . By the 1970s, Japan and Western Europe rebuilt their economies, allowing them more diplomatic independence. After the Sino-Soviet split between the USSR and China in 1961, the U.S. initiated contacts with China in 1972 . In the same year, the US and USSR signed a series of treaties limiting their nuclear arsenals, which eased tensions for

8964-430: The missile carries the equipment needed to transmit the radiation needed to illuminate the target and receive the reflected energy. Once the homing is initiated, the missile directs independently towards the target. In semi-active systems, the source of the radiation is located outside the missile usually in the launch vehicle which might be an aircraft or a ship and the missile will receive the radiation to direct towards

9072-414: The most prominent architects of America's early Cold War strategy, especially those who believed that the Cold War would eventually be fought by political rather than military means, such as George F. Kennan. Soviet and Eastern Bloc authorities used various methods to suppress Western broadcasts, including radio jamming . American policymakers, including Kennan and John Foster Dulles , acknowledged that

9180-671: The policy change. Once again, the East Berlin communists attempted to disrupt the Berlin municipal elections , which were held on 5 December 1948 and produced a turnout of 86% and an overwhelming victory for the non-communist parties. The results effectively divided the city into East and West, the latter comprising US, British and French sectors. 300,000 Berliners demonstrated and urged the international airlift to continue, and US Air Force pilot Gail Halvorsen created " Operation Vittles ", which supplied candy to German children. The Airlift

9288-441: The political decision-making level on either side. Similarly, there is no evidence, on either side, of any major political or military decision that was prematurely discovered through espionage and thwarted by the other side. There also is no evidence of any major political or military decision that was crucially influenced (much less generated) by an agent of the other side. According to historian Robert L. Benson, "Washington's forte

9396-591: The precursor to modern missiles and the first rockets were used as propulsion systems for arrows as early as the 10th century in China . Usage of rockets as weapons before modern rocketry is attested to in China, Korea , India and Europe . In the 18th century, iron-cased rockets were used in India by the Kingdom of Mysore and Maratha Empire against the British which was developed into Congreve rocket and used in

9504-479: The presence of the Red Army —alarmed the US and UK. Western leaders saw this as a clear instance of Soviet expansionism, clashing with their vision of a democratic Europe. Economically, the divide was sharpened with the introduction of the Marshall Plan in 1947, a US initiative to provide financial aid to rebuild Europe and prevent the spread of communism by stabilizing capitalist economies. The Soviet Union rejected

9612-469: The source of the term, Lippmann traced it to a French term from the 1930s, la guerre froide . The roots of the Cold War can be traced back to diplomatic and military tensions preceding World War II. The 1917 Russian Revolution and the subsequent Treaty of Brest-Litovsk , where Soviet Russia ceded vast territories to Germany, deepened distrust among the Western Allies. Allied intervention in

9720-463: The specific post-war geopolitical confrontation between the Soviet Union and the United States came in a speech by Bernard Baruch , an influential advisor to Democratic presidents, on 16 April 1947. The speech, written by journalist Herbert Bayard Swope , proclaimed, "Let us not be deceived: we are today in the midst of a cold war." Newspaper columnist Walter Lippmann gave the term wide currency with his book The Cold War . When asked in 1947 about

9828-407: The target, the target might required to be tracked continuously if it is in motion. A guidance system might use INS which consists of a gyroscope and accelerometer or might use satellite guidance (such as GPS ) to track the missile’s position relative to a known target. The missile computers will compute the flight path required to steer the missile towards the target. In command guidance ,

9936-429: The target. As the source is located outside, the launch vehicle needs to continue supporting the missile till it is guided to the intended target. In a passive system, the missile relies solely on the information from the target. The homing system might use light such as infrared , laser or visible light , radio waves or other electromagnetic radiation to illuminate the target. Once the guidance system identifies

10044-405: The two superpowers , though each supported opposing sides in major regional conflicts known as proxy wars . Aside from the nuclear arms race starting in 1949 and conventional military deployment , the struggle for dominance was expressed indirectly via psychological warfare , propaganda campaigns , espionage , far-reaching embargoes , sports diplomacy , and technological competitions such as

10152-411: The world, while Soviet involvement in regime change included the funding of left-wing parties , wars of independence , revolutions and dictatorships. As nearly all the colonial states underwent decolonization and achieved independence in the period from 1945 to 1960, many became Third World battlefields in the Cold War. At the end of World War II, English writer George Orwell used cold war , as

10260-486: The world. Movements against nuclear weapons testing and for nuclear disarmament took place, with large anti-war protests . By the 1970s, both sides had started making allowances for peace and security, ushering in a period of détente that saw the Strategic Arms Limitation Talks and the 1972 visit by Richard Nixon to China that opened relations with China as a strategic counterweight to

10368-505: Was 'signals' intelligence - the procurement and analysis of coded foreign messages." leading to the Venona project or Venona intercepts, which monitored the communications of Soviet intelligence agents. Moynihan wrote that the Venona project contained "overwhelming proof of the activities of Soviet spy networks in America, complete with names, dates, places, and deeds." The Venona project

10476-606: Was a period of global geopolitical tension and struggle for ideological and economic influence between the United States and the Soviet Union (USSR) and their respective allies, the Western Bloc and the Eastern Bloc , that started in 1947, two years after the end of World War II , and lasted until the fall of the Soviet Union in 1991. The term cold war is used because there was no direct fighting between

10584-412: Was a strong promise that West Germany would not develop nuclear weapons. Widespread fears of another rise of German militarism necessitated the new military to operate within an alliance framework under NATO command. In 1955, Washington secured full German membership of NATO. In May 1953, Lavrentiy Beria , by then in a government post, had made an unsuccessful proposal to allow the reunification of

10692-567: Was also fearful of a reconstituted Germany; his vision of a post-war Germany did not include the ability to rearm or pose any kind of threat to the Soviet Union. In early 1948, following reports of strengthening "reactionary elements", Czech Communists executed a coup d'état in Czechoslovakia (resulting in the formation of the Czechoslovak Socialist Republic (9 May 1948)), the only Eastern Bloc state that

10800-548: Was as much a logistical as a political and psychological success for the West; it firmly linked West Berlin to the United States. In May 1949, Stalin backed down and lifted the blockade. In 1952, Stalin repeatedly proposed a plan to unify East and West Germany under a single government chosen in elections supervised by the United Nations, if the new Germany were to stay out of Western military alliances, but this proposal

10908-679: Was contingent upon German economic recovery. One month later, Truman signed the National Security Act of 1947 , creating a unified Department of Defense , the Central Intelligence Agency (CIA), and the National Security Council (NSC). These would become the main bureaucracies for US defense policy in the Cold War. Stalin believed economic integration with the West would allow Eastern Bloc countries to escape Soviet control, and that

11016-472: Was kept highly secret even from policymakers until the Moynihan Commission in 1995. Despite this, the decryption project had already been betrayed and dispatched to the USSR by Kim Philby and Bill Weisband in 1946, as was discovered by the US by 1950. Nonetheless, the Soviets had to keep their discovery of the program secret, too, and continued leaking their own information, some of which

11124-506: Was left as the world's sole superpower. In February 1946, George F. Kennan 's " Long Telegram " from Moscow to Washington helped to articulate the US government's increasingly hard line against the Soviets, which would become the basis for US strategy toward the Soviet Union for the duration of the Cold War. The telegram galvanized a policy debate that would eventually shape the Truman administration 's Soviet policy. Washington's opposition to

11232-545: Was now restricted to the island of Taiwan , the nationalist government of which exists to this day. The Kremlin promptly created an alliance with the newly formed People's Republic of China. According to Norwegian historian Odd Arne Westad , the communists won the Civil War because they made fewer military mistakes than Chiang Kai-Shek made, and because in his search for a powerful centralized government, Chiang antagonized too many interest groups in China. Moreover, his party

11340-403: Was parity in the quantity and quality of secret information obtained by each side. However, the Soviets probably had an advantage in terms of HUMINT (human intelligence or interpersonal espionage) and "sometimes in its reach into high policy circles." In terms of decisive impact, however, he concludes: We also can now have high confidence in the judgment that there were no successful "moles" at

11448-494: Was still useful to the American program. According to Moynihan, even President Truman may not have been fully informed of Venona, which may have left him unaware of the extent of Soviet espionage. Clandestine atomic spies from the Soviet Union, who infiltrated the Manhattan Project at various points during WWII, played a major role in increasing tensions that led to the Cold War. In addition to usual espionage,

11556-655: Was turned down by the Western powers. Some sources dispute the sincerity of the proposal. Britain, France, the United States, Canada and eight other western European countries signed the North Atlantic Treaty of April 1949, establishing the North Atlantic Treaty Organization (NATO). That August, the first Soviet atomic device was detonated in Semipalatinsk , Kazakh SSR . Following Soviet refusals to participate in

11664-487: Was weakened during the war against Japan . Meanwhile, the communists told different groups, such as the peasants, exactly what they wanted to hear, and they cloaked themselves under the cover of Chinese nationalism . Confronted with the communist revolution in China and the end of the American atomic monopoly in 1949, the Truman administration quickly moved to escalate and expand its containment doctrine. In NSC 68 ,
