Tag first intercontinental ballistic missile

The first intercontinental ballistic missile (ICBM) was the R-7 Semyorka, developed by the Soviet Union in the late 1950s. It was designed by Sergei Korolev and his team at OKB-1, and it was first launched on August 21, 1957.

The R-7 Semyorka was a liquid-fueled ICBM that stood 34 meters (112 feet) tall and had a diameter of 3 meters (10 feet). It was powered by four stages, each fueled by a combination of kerosene and liquid oxygen. The missile had a maximum range of approximately 8,000 kilometers (5,000 miles), making it capable of reaching targets in Europe and Asia.

The R-7 Semyorka was first tested on August 21, 1957, when it was launched from the Baikonur Cosmodrome in Kazakhstan. The test was successful, and the missile reached an altitude of 200 kilometers (124 miles) before splashing down in the Pacific Ocean.

The R-7 Semyorka was later used as the launch vehicle for the Soviet Union's first artificial satellite, Sputnik 1, which was launched on October 4, 1957. It was also used to launch the first human into space, Yuri Gagarin, on April 12, 1961.

Here are some key specifications of the R-7 Semyorka:

The R-7 Semyorka was a significant milestone in the development of ICBMs, and it played a key role in the Cold War era. It was also a precursor to the development of more advanced ICBMs, such as the R-9 and R-16, which were used by the Soviet Union during the 1960s and 1970s.
