Remember the B-58? It had a service life of 10 years, was an expensive machine to operate, expensive to build and purchase and had less conventional capability than factory fresh B-1’s. Yet, I have read a number of articles slating such a short service life.
The B-1 retirement would be even worse as, lets not forget, the B-1B entered service in 1985, giving SIX years of service!!!! Most cars last longer than this!!!!
