9. Designed for a lifespan of 30 years
Unlike the previous version with small lifespan, the F-22 is designed to last over 30 years or 8,000hrs of flight time. Therefore until in the 2030s the F-22 will be reigning the skies in their fast speed.
Later there will be a sixth generation of fighter jets which will have added speed and lifespan. Therefore the new fighter jets would probably last to 50 years or so.
