The U.S. Air Force is flying its oldest fleet ever.

In 2025, the average USAF aircraft is 32 years old — older than at any point since the service was founded in 1947.

Jets designed for a different era, the Cold War, are now carrying today’s missions: global deterrence, high-tempo deployments, and the looming reality of great-power conflict. Maintenance costs are climbing, availability is shrinking, and every dollar spent keeping yesterday’s aircraft airborne is a dollar not spent on tomorrow’s replacements.

Now to be clear, I didn’t want to write a story about nostalgia or “they don’t build ’em like they used to.”

Instead, I’ve tried to frame it as a crossroads moment — where hard choices about retirement, replacement, and modernization will define airpower for decades.

I break down how we got here, what it means for bombers, fighters, tankers, and allies — and why the maintenance spiral is so dangerous — in today’s newsletter.
