I want to know the answer to the following question:
When were the military leaders replaced after a scandal over failure to maintain its nuclear arsenal?
All the background I'm provided with is that "As a result, the USAF fleet is setting new records for average aircraft age and needs to replace its fleets of fighters, bombers, airborne tankers, and airborne warning aircraft, in an age of restrictive defense budgets.". Is that enough to answer the question?
