LR79

Rocketdyne LOx/Kerosene rocket engine family. Designed for booster applications. Originally evolved in the Navaho program into the most powerful available Lox/Kerosene engine available in the United States at the dawn of the space age. Its descendants and derivatives powered Atlas, Titan, Thor, Saturn I, British Blue Streak, Japanese H2 launch vehicles into the 21st Century.
