World's First ICBM and Space Launcher: Early Years of R-7 Rocket

Mike Gruntman

Abstract

The historic first intercontinental ballistic missile R-7 (ICBM SS-6) placed the first artificial satellites into orbit in 1957, ushering in the space age. This Soviet two-stage rocket relied on radio control from the ground during the powered ascent. The control system used two remote radio control posts, RUPs, and an onboard computing unit to steer the missile. This design significantly complicated rocket deployment as a weapon and limited it to launching satellites into orbits with only one possible inclination. The reasons for choosing the implemented radio control and the gradual elimination of its weaknesses are poorly known. The article focuses on the early years of the R-7 and its evolution and trials at the Tyuratam Missile Test Range, also known as the Baikonur cosmodrome, in the late 1950s. Analysis of declassified Soviet government documents, CIA intelligence reports, and Corona reconnaissance photographs led to locating the RUP radio control outposts that supported R-7 launches. The official records of the ICBM tests and launches of the first Earth-orbiting artificial satellites and space probes to the moon and planets in 1957-1960 show the enormous scale and technical challenges of developing and modifying the rocket. The Soviet military operationally deployed the SS-6 only in limited numbers from 1960-1967. The new ballistic missiles relying on storable propellants began to supersede this liquid-oxygen-kerosene ICBM in the early 1960s. The inertial control systems also replaced cumbersome radio control, and the modernized R-7 rocket evolved into a successful family of efficient Soyuz space launchers, placing satellites into orbit to this day.
