re: #297 Feline Fearless Leader

My question regarding the A-10 is whether the fixed-wing GS plane still requires being built around a 30mm tank-killer cannon. Given the accuracy of JDAM or laser-designator bombs and the widespread availability of MANPAD systems has the support role moved to a higher altitude and thus no longer needs to be centered around the cannon armament?

It’s still one of the premiere GS platforms, but could it be partially redesigned to be even more effective in the current day military environment?

Everything I’ve read from someone who isn’t an AF paper-pusher says the A-10 is the shit, and still has usefulness.
