98-463: Grushin MKB Fakel (missile developer), The S-75 (Russian: С-75; NATO reporting name SA-2 Guideline ) is a Soviet-designed, high-altitude air defence system. It is built around a surface-to-air missile with command guidance . Following its first deployment in 1957 it became one of the most widely deployed air defence systems in history. It scored the first destruction of an enemy aircraft by
196-633: A UN resolution to establish a nuclear-free zone in Latin America when the other Soviet-aligned countries abstained, or why in 1964 Romania opposed the Soviet-proposed "strong collective riposte" against China (and these are examples solely from the 1963–1964 period). Soviet disinformation tried to convince the West that Ceaușescu's empowerment was a dissimulation in connivance with Moscow. To an extent this worked, as some historians came to see
294-520: A conventional warhead of similar weight. Typical range for the missile is about 45 km (28 mi), with a maximum altitude around 20,000 m (66,000 ft). The radar and guidance system imposed a fairly long short-range cutoff of about 500 to 1,000 m (1,600 to 3,300 ft), making them fairly safe for engagements at low level. The S-75 typically uses the P-12 early warning radar (also known by its NATO codename, "Spoon Rest"), which has
392-467: A lethal radius of about 65 m (200 ft) at lower altitudes, but at higher altitudes the thinner atmosphere allows for a wider radius of up to 250 m (800 ft). The missile itself is accurate to about 75 m (250 ft), which explains why two were typically fired in a salvo. One version, the S-75AK, mounted a 295 kg (650 lb) nuclear warhead of an estimated 15 kiloton yield or
490-708: A missile, the Shrike could be neutralized with the side-pointing technique without sacrificing any S-75s. Another tactic was a "false launch" in which missile guidance signals were transmitted without a missile being launched. This could distract enemy pilots, or even occasionally cause them to drop ordnance prematurely to lighten their aircraft enough to dodge the nonexistent missile. At the same time, evasive maneuvers were used, and intensive bombardments of identified SAM firing positions were organized. Under these conditions, camouflage and radio silence became especially important. After combat launches, an anti-aircraft missile division

882-435: A range of about 275 km (171 mi). The P-12 provides early detection of incoming aircraft, which are then handed off to the acquisition Fan Song radar. These radars, having a range of about 65 km (40 mi), are used to refine the location, altitude, and speed of the hostile aircraft. The Fan Song system consists of two antennas operating on different frequencies, one providing elevation (altitude) information and
980-581: A site in October 1965. The Air Force fitted B-66 bombers with powerful jammers (which blinded the early warning radars) and developed smaller jamming pods for fighters (which denied range information to enemy radars). Later developments included the Wild Weasel aircraft, which were fitted with AGM-45 Shrike missile systems made to home in on the radar from the threat. The Soviets and Vietnamese were able to adapt to some of these tactics. The USSR upgraded

This success was credited to Chinese fighter aircraft at the time to keep the S-75 program secret. This system first gained international fame when an S-75 battery, using the newer, longer-range, higher-altitude V-750VN (13D) missile

One of the founding members, East Germany , was allowed to re-arm by the Soviet Union and the National People's Army was established as the armed forces of the country to counter the rearmament of West Germany. The USSR concentrated on its own recovery, seizing and transferring most of Germany's industrial plants, and it exacted war reparations from East Germany, Hungary , Romania , and Bulgaria using Soviet-dominated joint enterprises. It also instituted trading arrangements deliberately designed to favour

On 14 May 1955, the USSR and seven other Eastern European countries "reaffirming their desire for
7252-656: The other azimuth (bearing) information. Regimental headquarters also include a Spoon Rest, as well as a Flat Face long-range C-band radar and Side Net height-finder. Information from these radars is sent from the regiment down to the battalion Spoon Rest operators to allow them to coordinate their searches. Earlier S-75 versions used a targeting radar known as Knife Rest, which was replaced in Soviet use, but can still be found in older installations. Upgrades to anti-aircraft missile systems typically combine improved missiles, radars, and operator consoles. Usually missile upgrades drive changes to other components to take advantage of
7350-649: The question of the participation of the USSR in the North Atlantic bloc", specifying that "the admittance of the USA into the General European Agreement should not be conditional on the three Western powers agreeing to the USSR joining the North Atlantic Pact". Again, all Soviet proposals, including the request to join NATO, were rejected by the UK, US, and French governments shortly after. Emblematic
7448-450: The radar several times to improve electronic countermeasure (ECM) resistance. They also introduced a passive guidance mode, whereby the tracking radar could lock onto the jamming signal itself and guide missiles directly towards the jamming source. This also meant the SAM site's tracking radar could be turned off, which prevented Shrikes from homing in on it. New tactics were developed to combat
7546-485: The reach of Vietnamese anti-aircraft guns. On July 24, 1965, four US Air Force McDonnell F-4C Phantoms took part in an airstrike against the Điện Biên Phủ munitions storage depot and the Lang Chi munitions factory west of Hanoi. One was shot down and three damaged by S-75s. This was the first time US aircraft were attacked by SAMs. Two days later President Johnson gave the order to attack known S-75 positions outside
7644-452: The region, such as Czechoslovakia and Poland. At the start of 1990, the Soviet foreign minister, Eduard Shevardnadze , implicitly confirmed the lack of Soviet influence over Ceaușescu's Romania. When asked whether it made sense for him to visit Romania less than two weeks after its revolution , Shevardnadze insisted that only by going in person to Romania could he figure out how to "restore Soviet influence". Romania requested and obtained
7742-566: The remaining US aircraft suffered damage from ground fire. However, the Vietnamese had replaced the SAMs with white-painted bundles of bamboo . Operation Spring High had destroyed two decoy targets for the loss of six aircraft and five pilots. Between 1965 and 1966 the US developed countermeasures to the S-75 threat. The Navy soon had the AGM-45 Shrike anti-radiation air-to-surface missile in service and mounted their first offensive strike on
7840-478: The six remaining member states. The USSR itself was dissolved in December 1991 , although most of the former Soviet republics formed the Collective Security Treaty Organization shortly thereafter. In the following 20 years, the Warsaw Pact countries outside the USSR each joined NATO (East Germany through its reunification with West Germany; and the Czech Republic and Slovakia as separate countries), as did
7938-621: The spread of the Revolutions of 1989 through the Eastern Bloc, beginning with the Solidarity movement in Poland, its electoral success in June 1989 and the Pan-European Picnic in August 1989. East Germany withdrew from the pact following German reunification in 1990. On 25 February 1991, at a meeting in Hungary, the pact was declared at an end by the defense and foreign ministers of
8036-446: The system was sold to most Warsaw Pact countries and was provided to China, North Korea, and eventually, North Vietnam. While the shooting down of Francis Gary Powers' U-2 in 1960 is the first publicized success for the S-75, the first aircraft shot down by the S-75 was a Taiwanese Martin RB-57D Canberra high-altitude reconnaissance aircraft . The aircraft was hit by a Chinese-operated S-75 site near Beijing on October 7, 1959. Over
8134-461: The treaty signatories were based upon mutual non-intervention in the internal affairs of the member countries, respect for national sovereignty , and political independence. However, de facto , the Pact was a direct reflection of the USSR's authoritarianism and undisputed domination over the Eastern Bloc , in the context of the so-called Soviet Empire , which was not comparable to that of
8232-688: The two countries. Consequently, the Soviets initiated the development of improved air defence systems. Although the Soviet Air Defence Forces had large numbers of anti-aircraft artillery (AAA), including radar-directed batteries, the limitations of guns versus high-altitude jet bombers were obvious. Therefore, the Soviet Air Defence Forces began the development of missile systems to replace the World War II-vintage gun defences. In 1953, KB-2 began
8330-501: The unified Germany (thus rendering the EDC obsolete). But Eden, Dulles, and Bidault opposed the proposal. One month later, the proposed European Treaty was rejected not only by supporters of the EDC, but also by Western opponents of the European Defence Community (like French Gaullist leader Gaston Palewski ) who perceived it as "unacceptable in its present form because it excludes the USA from participation in
8428-567: The usage of the term "independent" to describe Romania's relations with the Soviet Union, favoring "autonomy" instead on account of the country's continued membership within both the Comecon and the Warsaw Pact along with its commitment to socialism, this approach fails to explain why in July 1963 Romania blocked Mongolia 's accession to the Warsaw Pact, why in November 1963 Romania voted in favor of
8526-652: The wider public first became aware of the S-75 when the missile was shown at that year's May Day parade in Moscow . Wide-scale deployment started in 1957, with various upgrades following over the next few years. The S-75 was never meant to replace the S-25 Berkut surface-to-air missile sites around Moscow , but it did replace high-altitude anti-aircraft guns, such as the 130 mm (5.1 in) KS-30 and 100 mm (3.9 in) KS-19 . Between mid-1958 and 1964, US intelligence assets located more than 600 S-75 sites in
8624-434: The world as the "third force" of the Communist world. Romania's independence – achieved in the early 1960s through its freeing from its Soviet satellite status – was tolerated by Moscow because Romania was not bordering the Iron Curtain – being surrounded by socialist states – and because its ruling party was not going to abandon communism. Although certain historians such as Robert King and Dennis Deletant argue against
8722-463: Was "persuasively genuine". In truth, the Soviets were not beyond publicly aligning themselves with the West against the Romanians at times. The strategy behind the formation of the Warsaw Pact was driven by the desire of the Soviet Union to prevent Central and Eastern Europe being used as a base for its enemies. Its policy was also driven by ideological and geostrategic reasons. Ideologically,
8820-548: Was conceived, NATO officials labeled it a "cardboard castle". The USSR, fearing the restoration of German militarism in West Germany, had suggested in 1954 that it join NATO, but this was rejected by the US. The Soviet request to join NATO arose in the aftermath of the Berlin Conference of January–February 1954. Soviet foreign minister Molotov made proposals to have Germany reunified and elections for
8918-500: Was deployed in the 1960 U-2 incident , when it shot down the U-2 of Francis Gary Powers overflying the Soviet Union on May 1, 1960. The system was also deployed in Cuba during the Cuban Missile Crisis , when it shot down another U-2 (piloted by Rudolf Anderson ) overflying Cuba on October 27, 1962, almost precipitating a nuclear war. North Vietnamese forces used the S-75 extensively during
9016-465: Was little inclination in Western capitals to explore this offer" from the USSR, while historian Rolf Steininger asserts that Adenauer's conviction that "neutralization means sovietization ", referring to the Soviet Union's policies towards Finland known as finlandization , was the main factor in the rejection of the Soviet proposals. Adenauer also feared that German unification might have resulted in
9114-466: Was not a member of the Warsaw Pact). The Romanian regime was largely impervious to Soviet political influence, and Ceaușescu was the only declared opponent of glasnost and perestroika . On account of the contentious relationship between Bucharest and Moscow, the West did not hold the Soviet Union responsible for the policies pursued by Bucharest. This was not the case for the other countries in
9212-440: Was the only non-Soviet Warsaw Pact member which was not obliged to militarily defend the Soviet Union in case of an armed attack. Bulgaria and Romania were the only Warsaw Pact members that did not have Soviet troops stationed on their soil. In December 1964, Romania became the only Warsaw Pact member (save Albania, which would leave the Pact altogether within 4 years) from which all Soviet advisors were withdrawn, including those in
9310-400: Was the position of British General Hastings Ismay , a fierce supporter of NATO expansion . He opposed the request to join NATO made by the USSR in 1954 saying that "the Soviet request to join NATO is like an unrepentant burglar requesting to join the police force". In April 1954, Adenauer made his first visit to the United States, meeting Nixon , Eisenhower , and Dulles . Ratification of
9408-476: Was to leave the area immediately, otherwise it would be destroyed by a bombing attack. Until December 1965, according to American data, eight S-75M systems were destroyed, although sometimes American aircraft bombed dummy positions equipped with decoy missiles made of bamboo . Soviet and Vietnamese calculations claimed the destruction of 31 aircraft; the Americans acknowledged the loss of 13 aircraft. According to
9506-474: Was too damaged to fly again. During the Vietnam war, the Soviet Union delivered 95 S-75 systems and 7,658 missiles to the Vietnamese. 6,806 missiles were launched or removed by outdating. According to the Vietnamese, the S-75 shot down 1,046 aircraft, or 31% of all downed US aircraft. By comparison, air-defense guns brought down 60% and 9% were shot down by MiG fighters. The higher rate of anti-aircraft artillery
9604-668: Was two-fold: the Political Consultative Committee handled political matters, and the Combined Command of Pact Armed Forces controlled the assigned multi-national forces, with headquarters in Warsaw , Poland. Although an apparently similar collective security alliance, the Warsaw Pact differed substantially from NATO. De jure , the eight-member countries of the Warsaw Pact pledged the mutual defense of any member who would be attacked; relations among
