Doesn’t seem so bad when a single B-2 costs about the same amount. B-52’s mission is based on logistics and the US having air superiority. As long as we maintain that superiority, it doesn’t matter what system delivers the hurt. C-130, A-10, F-16 and many others are all old airframes as well. But they still excel at their designed roles. Again…provided we own the skies.
I do get concerned as I watch the proliferation of drones as the modern weapon of choice. It seems there may be a shift in how combat will be executed in the future. Specifically swarms of small, cheap, self-destructive, semi-autonomous things running around may be more effective than entire air forces.
