The most recent, planned, retirement of B-1s was 3 years ago, in 2021, a group of 17. The previous batch of 33 were retired in 2003. Since then a few B-1s (1 or 2?) have, like a few retired B-52s, been pulled out of retirement, refurbished. and returned to operation. The USAF has been doing this sort of thing for decades: unfamiliar normal may be good clickbait, but it is not a crisis, or even all that newsworthy.
