Not backward at all. At the speed and altitude these jets are flying, every pilot is looking through their sensor straws to aim their IR and LG weapons these days. If you don’t fly, try play DCS’ A-10 sim sometime, unless someone is shooting tracer rounds or missiles with smoky trails…. most time you be looking at the CMFD for the bad guys
I mean we do need some A-10 like airplanes around, just in case the Ruskis rally up their tank formations again, but 90% of what we’ll be seeing in the next few decades will be bombing out armored pickup trucks in a populated civilian environment. U don’t really need varied loads of weapon to do that, some simple guided rockets will do the job.
