But how many Falcon Heavy launches could you get for the cost of one SLS launch?
Well givne the 10 yrs from 2011 cost the US taxpayers $23Bn and lets say a NASA specific FH launch was $200m (with all the NASA specific "mission assurance" special sauce they need) that's 115 launches worth. Of course FH has only been flying since 2018 so tha's only $9.2Bn pro rata. Only 46 launches.
But this misses the key metric.
The number of jobs in Alabama that the Senator for Alabama can claim he's bought to the state.
