A popcorn fart compared to Saturn-5 which was built in the 60s. It needs to be 2x as powerful to put a significant lead over Saturn - 5.

The FH will be two thirds the thrust of the Saturn V. It will be twice the thrust of any other launcher currently in service. In fact, a problem with the FH is there are so few customers who will need that much lift.
BTW, SpaceX’s next rocket will have more payload capability than the Saturn V, and be completely reusable. It will be so cost efficient that it will be able to replace the Falcon 9 and Falcon Heavy.
FH = ??
