Why is NASA using the Delta IV Heavy instead of building more Saturn V’s?
Its costs. We don't need the power of a Saturn V for most launches. Most of the fuel burned in a launch is used to lift fuel.
The Short Answer
Its costs. We don't need the power of a Saturn V for most launches. Most of the fuel burned in a launch is used to lift fuel. A Saturn V that holds a significantly more fuel than a Delta IV (6,540,000 lbs vs 1,616,000 lb most of which is fuel). If the payload doesn't require that much thrust to lift off why spend the money to lift the fuel you didn't need?
