Older airframes
Yes, I agree that it is wise of the USAF to keep some older airframes. A very good example is the B52 which will reach its 100 anniversary! The Jaguar and Harrier should never have been scrapped, just to save short term cuts. The VC10 should have been modernised and would have been a far cheaper option than what little assets replaced it. As for our maritime capability! Etc etc
