The U.S. Air Force has all but given up on retiring the A-10 Warthog close-air-support jet. Instead, the flying branch is upgrading the tough ground-attackers so they can fight and survive in high-intensity combat.
The Air Force had hoped to begin retiring its 281 A-10s starting in 2015. But Congress blocked the effort. Now the A-10 is safe even as the Air Force considers retiring other plane types.
