>we want a medium-altitude, long-endurance bomb truckaerodynamic principles and the laws of physics really limit what you can effectively do with those parameters. It wasn't designed to go fast, it wasn't designed to go incredibly high, all it needed to do was deliver a payload to a target cheaply, which is why it's outlived everything else SAC ever ordered.
Sure, there are marginal efficiency gains from different engines, and deleting the tail gunner and some of the CSO stations as avionics advanced, but every single other thing you could do starts to compromise the design into another corner.
B52's on fucking mars baby.
