After World War II drew to a close in the mid-20th century, a new conflict began. Known as the Cold War, this battle pitted the world’s two great powers–the democratic, capitalist United States and the communist Soviet Union–against each other. Beginning in the late 1950s, space would become another dramatic arena for this competition, as each side sought to prove the superiority of its technology, its military firepower and–by extension–its political-economic system.

By the mid-1950s, the U.S.-Soviet Cold War had worked its way into the fabric of everyday life in both countries, fueled by the arms race and the growing threat of nuclear weapons, wide-ranging espionage and counter-espionage between the two countries, war in Korea and a clash of words and ideas carried out in the media. These tensions would continue throughout the space race, exacerbated by such events as the construction of the Berlin Wall in 1961, the Cuban missile crisis of 1962 and the outbreak of war in Southeast Asia.

Space exploration served as another dramatic arena for Cold War competition. On October 4, 1957, a Soviet R-7 intercontinental ballistic missile launched Sputnik (Russian for “traveler”), the world’s first artificial satellite and the first man-made object to be placed into the Earth’s orbit. Sputnik’s launch came as a surprise, and not a pleasant one, to most Americans. In the United States, space was seen as the next frontier, a logical extension of the grand American tradition of exploration, and it was crucial not to lose too much ground to the Soviets. In addition, this demonstration of the overwhelming power of the R-7 missile–seemingly capable of delivering a nuclear warhead into U.S. air space–made gathering intelligence about Soviet military activities particularly urgent.

NASA Is Created

In 1958, the U.S. launched its own satellite, Explorer I, designed by the U.S. Army under the direction of rocket scientist Wernher von Braun. That same year, President Dwight D. Eisenhower signed a public order creating the National Aeronautics and Space Administration (NASA), a federal agency dedicated to space exploration.

Eisenhower also created two national security-oriented space programs that would operate simultaneously with NASA’s program. The first, spearheaded by the U.S. Air Force, dedicated itself to exploiting the military potential of space. The second, led by the Central Intelligence Agency (CIA), the Air Force and a new organization called the National Reconnaissance Office (the existence of which was kept classified until the early 1990s) was code-named Corona; it would use orbiting satellites to gather intelligence on the Soviet Union and its allies.

Space Race Heats Up: Men (And Chimps) Orbit Earth

In 1959, the Soviet space program took another step forward with the launch of Luna 2, the first space probe to hit the moon. In April 1961, the Soviet cosmonaut Yuri Gagarin became the first person to orbit Earth, traveling in the capsule-like spacecraft Vostok 1. For the U.S. effort to send a man into space, dubbed Project Mercury, NASA engineers designed a smaller, cone-shaped capsule far lighter than Vostok; they tested the craft with chimpanzees, and held a final test flight in March 1961 before the Soviets were able to pull ahead with Gagarin’s launch. On May 5, astronaut Alan Shepard became the first American in space (though not in orbit).

Later that May, President John F. Kennedy made the bold, public claim that the U.S. would land a man on the moon before the end of the decade. In February 1962, John Glenn became the first American to orbit Earth, and by the end of that year, the foundations of NASA’s lunar landing program–dubbed Project Apollo–were in place.

Achievements of Apollo

From 1961 to 1964, NASA’s budget was increased almost 500 percent, and the lunar landing program eventually involved some 34,000 NASA employees and 375,000 employees of industrial and university contractors. Apollo suffered a setback in January 1967, when three astronauts were killed after their spacecraft caught fire during a launch simulation. Meanwhile, the Soviet Union’s lunar landing program proceeded tentatively, partly due to internal debate over its necessity and to the untimely death (in January 1966) of Sergey Korolyov, chief engineer of the Soviet space program.

December 1968 saw the launch of Apollo 8, the first manned space mission to orbit the moon, from NASA’s massive launch facility on Merritt Island, near Cape Canaveral, Florida. On July 16, 1969, U.S. astronauts Neil Armstrong, Edwin “Buzz” Aldrin and Michael Collins set off on the Apollo 11 space mission, the first lunar landing attempt. After landing successfully on July 20, Armstrong became the first man to walk on the moon’s surface; he famously called the moment “one small step for man, one giant leap for mankind.”

Who Won the Space Race?

By landing on the moon, the United States effectively “won” the space race that had begun with Sputnik’s launch in 1957. For their part, the Soviets made four failed attempts to launch a lunar landing craft between 1969 and 1972, including a spectacular launch-pad explosion in July 1969. From beginning to end, the American public’s attention was captivated by the space race, and the various developments by the Soviet and U.S. space programs were heavily covered in the national media. This frenzy of interest was further encouraged by the new medium of television. Astronauts came to be seen as the ultimate American heroes, and earth-bound men and women seemed to enjoy living vicariously through them. Soviets, in turn, were pictured as the ultimate villains, with their massive, relentless efforts to surpass America and prove the power of the communist system.

With the conclusion of the space race, U.S. government interest in lunar missions waned after the early 1970s. In 1975, the joint Apollo-Soyuz mission sent three U.S. astronauts into space aboard an Apollo spacecraft that docked in orbit with a Soviet-made Soyuz vehicle. When the commanders of the two crafts officially greeted each other, their “handshake in space” served to symbolize the gradual improvement of U.S.-Soviet relations in the late Cold War-era.

Arms race, a pattern of competitive acquisition of military capability between two or more countries. The term is often used quite loosely to refer to any military buildup or spending increases by a group of countries. The competitive nature of this buildup often reflects an adversarial relationship. The arms race concept is also used in other fields. However, the discussion in this article is limited to military arms races.

Examples of arms races since the early 20th century

The Cold War nuclear arms race between the United States and the Soviet Union is another example of a 20th-century arms race. The United States’ use of nuclear weapons to end World War II led to a determined and soon successful effort by the Soviet Union to acquire such weapons, followed by a long-running nuclear arms race between the two superpowers. The Soviet Union conducted its first nuclear test in 1949. At the end of 1956, the United States had 2,123 strategic warheads and the Soviet Union had 84. Those numbers increased rapidly over the subsequent 30 years. The U.S. arsenal peaked in 1967 at more than 31,000 warheads, and the Soviet arsenal peaked about 20 years later at more than 40,000. The end of the Cold War by the early 1990s appeared to have ended that arms race. In 2019, however, the United States formally withdrew from the 1987 Intermediate-Range Nuclear Forces (INF) Treaty, citing multiple alleged violations of the agreement by Russia. Experts feared that the demise of the treaty, by which the United States and the Soviet Union had agreed to eliminate intermediate-range and shorter-range land-based missiles capable of carrying nuclear weapons, would lead to a new arms race.

Arms races may involve a more general competitive acquisition of military capability. This is often measured by military expenditure, although the link between military expenditure and capability is often quite weak. Such more general arms races are often observed among countries engaged in enduring rivalries, which may sometimes appear to follow each other’s military spending levels, especially during periods of heightened tension. Examples of such arms races include India-Pakistan, Israel–Arab states, Greece-Turkey, and Armenia-Azerbaijan.

Consequences of arms races

Arms races are frequently regarded as negative occurrences in both economic and security terms. Large-scale arms acquisitions require considerable economic resources. If two countries spend large sums of money just to cancel out each other’s efforts, the expenditure might well be seen as wasted. There is, however, considerable debate surrounding the economic effect of military spending. Some argue that it provides benefits through technological spin-offs, job creation, and infrastructure development. Others argue that it displaces more-productive forms of investment, while its final output is not itself productive. Certainly, countries that must import arms will see more negative economic effects of an arms race, and arms imports are a major contributor to debt in the developing world. Even for arms-producing countries, excessive military expenditure is likely eventually to have negative economic consequences. The Soviet Union’s economic difficulties were certainly exacerbated by the very high proportion of the gross domestic product devoted to the arms race.

The question of whether arms races contribute to the outbreak of war is also the subject of considerable debate. An arms race may heighten fear and hostility on the part of the countries involved, but whether this contributes to war is hard to gauge. Some empirical studies do find that arms races are associated with an increased likelihood of war. However, it is not possible to say whether the arms race was itself a cause of war or merely a symptom of existing tensions.

One may also consider the gains for a country that “wins” an arms race in the sense of gaining a decisive military advantage. Arguably, the collapse of the Soviet Union, which left the United States as the sole global superpower, was partly due to the cost of attempting to keep up with the United States.
