| | Yangel, Mikhail K. (1911-1971) |
 | | Yangel, Mikhail K. One of the three most important designers of liquid-propellant rockets in the Soviet Union, the other two being Sergei Korolev and Vladimir Chelomei. |
 | | Yangel began his career in the aviation industry and joined Korolev’s OKB-1 enterprise almost by chance. |
 | | However, Yangel quickly became a major competitor, not only as a developer of ICBMs, such as the R-12, R-14, and R-36 (see “R” series of Russian missiles) but also of several series of space launch vehicles, including the Zenit, Cosmos, and Tsyklon. |
