I was just looking at the A10 vs f35 specs and cost. If you put modern engines on a new A10, it would kick F35 butt for a fraction of the cost.
Infantry worship the A-10 as a god. It is the best close air support aircraft ever invented.
As a result of the Sequester, Air Force brass is trying to kill the A-10 to free up money for the F-35. That will result in battlefield deaths of grunts.
