Saturn MLV
The Saturn MLV was a proposed concept family of rockets, intended as a follow-on to the Saturn V. MLV stands for "Modified Launch Vehicle".
Vehicle configurations representative of several alternative uprating methods were specified by the Marshall Space Flight Center for initial studies.
Proposed modifications[]
- Thrust uprating and modifying of the five F-1 rocket engines used in the first S-IC stage, and corresponding increases in propellant tank capacities.
- Addition of a sixth F-1 engine in the S-IC stage, as an alternative to engine uprating, plus increased propellant capacities.
- Use of solid rocket motor boosters derived from the Titan IIIC vehicle.
- Additional J-2 engines in the S-II stage, ~131 s increased upper stage propellant capacities.
- Improved or advanced upper stage engines, such as the HG-3, plus increased propellant capacities.
The baseline Saturn MLV would incorporate these changes from the Saturn V vehicle. Saturn IC (first stage) stretched 240 inches with 5.6 million pounds propellant and five new F-1A engines; S-II (second stage) stretched 41 inches with 1.0 million pounds propellant and five J-2 engines; S-IVB (third stage) strengthened, but with standard 230,000 lbs propellant, one J-2 engine.
