The Saturn V was simply a scaled up V2. The critical components were all there:

1. boundary layer cooling

2. pre-heating fuel and cooling the nozzle by pushing the fuel through tubes in the nozzle

3. baffles to prevent pogo-ing

4. turbo fuel pumps

5. supersonic airframe

6. guidance system (although primitive)

The V2 was an ineffective military weapon that did little damage - because its guidance system was too primitive to be able to hit a target. Hitler also poured enormous resources into the V2 program, shifted away from producing weapons that were effective.
