One of the stated goals of the Space Shuttle solid rocket boosters (SRBs) was their re-usability and cost savings from such reuse. I know that many of them were reused, but in the end, how successful was the re-use goal for the SRBs in saving money? There was obviously significant teardown and refurbishment of these boosters, which I'm sure was not cheap.
But by the end of the Shuttle program:
- How many were re-used?
- What was the record for most flights for a single SRB (if you can count refurbishment and necessary parts replacement to still be the same SRB)?
- Did it actually save money over what the cost would have been for not trying to re-use these SRB's?
