I am wondering if the AF as seen the battlefield in Ukraine and decided that the A10 would not survive the modern air space?
Nothing will survive a lethal attack. Not the A-10 or the F-35 or the F-22. Not an Abrams tank; not a Patriot missile battery; not any helicopter.
Not a soldier. Not an aircraft carrier. Not an ICBM launch site.
That said, it doesn't mean these things are not essential.
The goal of the military is, first, prevent wars. Second, win those that get started. To win a military has to destroy the enemy at a rate the enemy can't sustain while taking losses at a rate it can sustain.
If used, A-10s will be at risk; so will every other weapon system.
