Very cool. I worked on B-1B test systems many years ago so this was an enjoyable read.
My brother is the supervisor of one of the avionics maintenance groups at Tinker for these things. I have seen them up close and personal. Beautiful piece of work. It’s amazing that we’ve been able to extend their life as long as we have. I think they stopped making them in 1988, this after the first unit flew in 1974.
I’ve read that the military can continue to upgrade and maintain the fleet into 2038. That says a lot for the design of this airplane.
