The defense news site Military.com is reporting, HERE, that although they are not giving up, the supporters of the A-10 Warthog seem to be fighting a losing battle against the opposition led by Secretary of Defense Hagel.  An excerpt:

The Air Force has proposed retiring the entire fleet of nearly 300 A-10 “Warthogs” — including more than 80 at Davis-Monthan — by 2019 to save some $4 billion, but backers say there’s no ready substitute with the A-10’s unique close-air support capabilities.

I hope the A-10 supporters are successful, as the F-35 seems to be far less capable as a close air support aircraft.
