Sputnik launch vehicle
The world's first launch vehicle to reach Earth orbit. It
was developed from the Soviet R-7 ballistic missile (see "R"
series of Russian missiles) and comprised a central core of four RD-107
rockets, clustered around which were four tapered booster stages each containing
four RD-108 rockets. All the engines used liquid oxygen and kerosene. During
ascent, the boosters were jettisoned, leaving the core to place the Sputnik
satellite in orbit.
