Jupiter (missile)

History of Jupiter

It is difficult to speak about the Jupiter missile without evoking the Redstone. The genesis of the Redstone goes back to 1948 but its design goes back to earlier still. Its history goes back to 1948, when the army contacts General Electric for the design of a missile with average carried. After various studies, a project is released. In 1952, it takes the name of Redstone. Redstone was developed by a team of German engineers brought back to the the United States after the defeat of 45, that one even which had conceived the V2 a few years before. Wernher von Braun, main uncontested German of engineering astronautics, is seen entrusting in July 1954, the development of a Jupiter missile whose range will be of 2400 km and which is a derivative of the military missile Redstone whose first stage is the same one. The following year, it is drawn for the first time since the site from Cap Canaveral. In December 1955, the American secretaries of the Army and Navy announced a program of terrestrial and naval armament in order to equip the bases with ballistic missiles. Jupiter was a shorter missile. It had been conceived to be embarked on the boats. The Marine withdrew it project in November 1956 in favor of an other missile: the Polaris. Jupiter was too broad to be embarked on board the Porte-avions. Even after being withdrawn from the Navy, IRBM Jupiter preserved its short dimensions.

A little later in November 1956, the ministry for National defense assigned with the US Air Force an important arsenal of land-based missiles Jupiter. The American Army had preserved missiles of a range of approximately 200 miles (320 km). The program of Jupiter IRBM was transferred to the American Air force. The US Air Force had already its own ballistic missile: the Thor. Until this moment, the Air force had always been unaware of the existence of Jupiter deliberately. Some make to a confusion with another rocket of the US Air Force called Jupiter-C. The Jupiter-C is a missile modified Redstone. Jupiter C combined a tank of Propergol liquid with two upper floors with powder. This rocket with vertical push was designed for the atmospheric sunken of warheads. It reaches 1000 km of altitude and 5300 km of distance. It was used to carry out trial flights and launched the first probes Explorer 1 and Explorer 3. The Jupiter-C with vertical push also was called fused Juno and Juno 1.

Saturn I and Saturn IB were rockets manufactured starting from the simple tank of Jupiter with which one combined and grouped around, eight other fuel tanks of Redstone rocket. It was the first powerful rocket of launching. Jupiter IRBM was also modified by adding upper floors in order to make of it a launch vehicle of satellites and space investigation. This modified Jupiter was called Juno-II.

Biological flights

The Jupiter missile was used within the framework of a series of suborbital biological trial flights. December 13rd 1958, Jupiter AM-13 was launched of Cap Canaveral in Florida with on its board a monkey squirrel of South America called " Gordo ". The data of telemetry sent during the flight showed that the monkey resisted 10 G of thorough (100 m/s ²), 8 minutes of weightlessness and 40 G (390 m/s ²) is 10 000 km/h (4,5 km/s) at its entry in the atmosphere. Unfortunately the parachute of help of the Ogive did not function and " Gordo " survived not the vol. the warhead ran with 1302 nautical miles (2411 km) with broad of Cap Canaveral and was not found.

Another biological flight took place on May 28th 1959. On board Jupiter IRBM AM-18, were embarked a Singe Rhesus of 3,2 kg (7 books) called " Whitebait " and a monkey squirrel of South America of 310g (11 ounces) called " Baker". The monkeys were placed in the warhead of the missile and envoys at an altitude of 360 miles (579 km) and at a distance from 1700 miles (2700 km) with broad of the base of Cap Canaveral. They resisted an acceleration 38 times higher than normal gravity and remained in weightlessness lasting approximately 9 minutes. They resisted at an high speed with 10 000 km/h (4,5 km/s) during 16 minutes of vol. After the sea landing, the Jupiter warhead which transported " Whitebait " and " Baker " was recovered in the sea by the WORN Kiowa ATF-72. The monkeys survived the flight but, four days afterwards, " Able" succumbed of one reaction to the anesthesia during an surgical operation intended to remove a medical electrode. " Baker " on November 29th 1984 with the " died; Alabama Space and Rocket Center " of Huntsville in Alabama. " Gordo ", " Whitebait " and " Baker " three of the many monkeys are right which were sent in space.

Military deployment

In April 1958, the Department of Defense of the United States informed the Air force of the United States which it had, as test, the intention to deploy the first three batteries of missiles Jupiter (45 missiles) in France. The negotiations between the France and the United States failed in June 1958. Charles de Gaulle, new French president, refused to accommodate the missiles Jupiter IRBM on the national territory. The United States studied the other possibilities of deploying them in Europe and Asia Mineure. They negotiated with the Italy and the Turkey.

Since 1959, USAF deployed four batteries (60 missiles) of missiles Thor in Great Britain around Nottingham. In the same year, in April 1959, the Air force of the United States deployed two batteries of Jupiter IRBM in Italy. The 30 missiles were installed in 10 Italian sites between 1961 and 1963. They were actuated by the Italian Air force, but the nuclear warheads were armed and ordered by the personnel of the Air force of the United States. The missiles were deployed in the Italian countryside and were actuated by the " 36e Aerobrigata Interdizione Strategica " , installed outside the air base of " Gioia LED Sticks " in Italy. One reports that in 1962, a plane Bulgare of recognition Mig-17 was crushed in an olive grove close to one of the sites of launching of Jupiter missiles in Italy, after having flown over the site.

During the administration Eisenhower, in October 1959, the Turkey and the US government signed an agreement on the installation of Jupiter IRBM on military bases of NATO in the south of the country.

15 missiles were deployed on 5 sites close to Izmir in Turkey between 1961 and 1963. They were actuated by the personnel of the Air force of the United States. The first flight of three Jupiter missiles was carried out in October 1962 on the initiative of the Türk Hava Kuvvetleri (the Turkish Air force) during the crisis of the missiles of Cuba. The personnel of the American Air force ordered and armed the nuclear warheads. The site of the Jupiter missiles in Turkey remains secret and this, more than 40 years after their installation. It would seem that according to those which took part in the installation of the missiles Turkish in 1961, one of the five sites was in the mountains close to Manisa and another was in the mountains close to Akhisar. The central base was the air base of Cigli.

On four occasions, between mid-October the 1961 and mid-August the 1962, of the mobile missiles Jupiter carrying of the nuclear warheads of 1,4 Megaton (5,9 PJ) were struck by the lightning in Italian bases. In each case, the thermal batteries were started, and on two occasions, the gas of “pushed” of Tritium-deuterium was injected into the warheads, arming them partially. To protect the various Italian sites and Turkish from the lightning, the Air force of the United States decided to place turn-lightning conductor around the installations.

Well before Jupiter Turkish are not installed, the missiles, able to reach the Soviet territory, were already mainly obsolete and increasingly vulnerable vis-a-vis possible Soviet attacks. As of 1961, the president John Fitzgerald Kennedy ordered the dismantling of all Jupiter IRBM. The Air force taken however of the delay in the cash withdrawals. The president was very in anger to learn that more than one year after, the missiles had still not been removed. The totality of Jupiter IRBM were put except service at April 1963. This operation was particularly useful because it contributed to defuse the Crise of the missiles of Cuba in October 1962. Indeed, within the framework of secret agreements between the Soviets and the Americans, the shrinking of the missiles Jupiter IRBM was a clause of the shrinking of the ballistic missiles installed with Cuba by the Soviet Union.
