The Rocketdyne S-3D (Air Force designation LR79) [1] [2] is an American liquid rocket engine produced by Rocketdyne (a division of North American Aviation) between 1956 and 1961. It was a gas generator, pump-fed engine, using a liquid oxygen (LOX) and RP-1 (kerosene) propellant combination, capable of producing 134,908 pounds of thrust (600.1 kN) at sea level. [3]
The S-3 was based on the Redstone engine, [4] and is part of the LR79 family, [5] [6] [1] [2] used on the PGM-19 Jupiter and PGM-17 Thor missiles, [7] [4] [8] and on the Juno II rocket. [3] [9] [10] [11]
A second stage with four S-3 engines was considered for the Saturn A-2 study. [12]
Its design was used later as the basis for the H-1 rocket engine of the Saturn I, [13] [1] [7] and the Rolls-Royce RZ.2 of the Blue Streak.
