Let face it the A-10 is best attack aircraft ever build.
A unique opportunity were Military, Politician and Engineers work together to create ultimate tank hunter
The A-10 Thunderbolt II is design for robust, reliability, Durability under extrem conditions
it got triple control systems, The cockpit is a Titan shell
It's designed to be refueled, rearmed, serviced and repaired with minimal equipment on Field
And what they wanted to replace it ? F-35, now the F-35 became zillion dollar project that's behind how many years ?
and now new A-X project, this time with meddling Politician in the game...
Scaled Composites ARES is nice concept for lightweight COIN aircraft, disposal after one mission.
or you beliefe it survive a mission that A-10 venture ?
The best thing they can do for moment is go to Northrop-Grumman (rights owner of Fairchild Republic)
and order New A-10, yes order new ones ! why change a success story ?
