Given the supportability issues, the cost of repair, the B-21 in early production, using the aircraft as a parts donor today to help keep the others mission capable makes the best of a bad situation. The parts can flow almost immediately, creating spares, adding margin and numbers to the overhauled parts availability which beats waiting years for it to be fixed.

Two choices, wait years to be fixed or strip it for parts today. It will fly again very soon, just not as an intact aircraft.
