How Crazy is Lifespan of America’s F35?

Lockheed Martin tests its limit to 24,000 hours!

What does a 24,000-hour lifespan mean for a fighter jet? The Russian Su-57 has a lifespan of only about 6,000 hours, just a quarter of this figure.

The 24,000-hour lifespan is the ultimate tested lifespan of the F35 by Lockheed Martin, making it a unique model in this field.

Also a fifth-generation fighter jet, neither the Su-57 nor the F22 can achieve this, so why is the F35 so exceptional?

Why is the lifespan so long?

The F35’s long lifespan is likely due to how the U.S. Air Force maintains this fighter jet.

Generally, fifth-generation stealth fighters are more “delicate” compared to earlier generations; their surfaces have a special coating that can lose effectiveness or even degrade under certain conditions.

As a result, besides missions, the F35 typically stays in a climate-controlled hangar in the U.S.

Such hangars maintain a stable temperature year-round, and based on actual needs, the U.S. Air Force can also adjust environmental factors like humidity…
