456 a year means more than one Starship every single day, all from one spot in Texas.
Each one sends two stages back to the tower.
At that pace the tower is the busiest part of the whole operation.
Starship Flight 15 is reportedly no earlier than 8 Nov, and Elon's goal this time is to catch the ship too.
SpaceX is asking to go from 25 Starship launches a year at Starbase to as many as 456.
Nobody builds 456 rockets a year. That number only works if both stages come back and fly again.
The proposal also counts 912 landings a year, about two for every launch.
The FAA has only started its review. Nothing is approved yet.
