B-1 never enjoyed the priority of the priority of the B-2 for support, so maintenance was deferred, and parts were harder to get. Plus, given the number of wars it's participated in with very rough missions including grouind support, the fleet is just wearing out. I believe the authorized fleet is down to 45 aircraft, with four more in reclaimable storage.
