SR-71 Ancestor Redesigned in 1961 to Carry Nuclear Bombs

Original: The SR-71 Blackbird's Ancestor Was Redrawn in 1961 to Carry 4 Nuclear Bombs at Mach 3.2 and 90,000 Feet, Then the Air Force Chose the 6-Engine XB-70 Valkyrie

The A-12 reconnaissance plane that led to the SR-71 Blackbird was reportedly redesigned in 1961 into a bomber variant able to carry four nuclear weapons at Mach 3.2 and altitudes up to 90,000 feet. The US Air Force ultimately passed on the concept, favoring the six-engine XB-70 Valkyrie bomber program instead.

Why now: Aviation history content about Mach 3 nuclear bomber concepts keeps drawing interest among defense and aerospace enthusiasts.
