Replacement Or Upgrade? The Fate Of The 5 Oldest US Military Aircraft Still Flying

The United States Air Force continues to operate old (very old) aircraft designs that trace their origins to the early Cold War. These are mostly larger transport/tanker/bomber-style aircraft ( fighter jets tend to be newer), and while some will retire, there is no end in sight for others. Missing from this list are aircraft like the iconic U-2 Dragon Lady spy plane as it is soon to retire. Incredibly, there may even be a few WWII-era aircraft still operating around the world.
