Why the XB-70 would not inherit the B-52's longevity

Replacing B-52s one for one with XB-70s creates a more specialised bomber force whose aircraft are less likely to remain useful for decades.

Question

What if the US Air Force replaced B-52s one for one with XB-70 Valkyries beginning in 1969?

Short answer

The XB-70s would probably leave service sooner because their specialised design was less adaptable than the B-52.

Notes

The XB-70 is admired as a striking design, but its strengths belong closely to the threat environment for which it was conceived. The B-52 is described as a more utilitarian bomb truck that can absorb new weapons and missions. A one-for-one Valkyrie fleet might therefore age out instead of receiving the B-52's exceptionally long service life. The comparison separates visual and technical ambition from the adaptability that sustains an aircraft across changing strategy.
