Mercury Project, Redstone Launch Vehicle Advanced Electrical Schematic Drawings

The Redstone engine is one of the most significant developments in US rocket technology. As the power plant for the Redstone missile, it was this country's first large-scale operational rocket engine. It went on to power the Jupiter-C, a modification of the Redstone missile that placed the US's first artificial satellite, Explorer 1, in 1958. In 1961, another modified Redstone, the Mercury-Redstone 3, launched the first American into space, Alan B. Shepard. The thrust of the engine as used in the Redstone missile was 78,000 lbs. As modified for use as a booster for Shepard's Mercury spacecraft, it produced 83,000 lbs of thrust.
