I often see the claim that the Shuttle SRBs cost as much to recover & refurb as it would to build a new one. I've probably even parroted this claim myself.
But, are there any actual studies or analysis on the economics of Shuttle SRB re-use? Are we all just repeating a Space Legend like these people did: Which LEO satellite lost over 30 km of altitude in the geomagnetic storm of 13-14 March 1989? ?
Is there any documentation to support the claim that it would it have been cheaper / essentially the same cost to build new boosters for each Shuttle flight?
