America is stuck with a $400 billion stealth fighter that can’t fight

Here’s something the public didn’t know until today: If one of the U.S. military’s new F-35 stealth fighters has to climb at a steep angle in order to dodge an enemy attack, design flaws mean the plane might suddenly tumble out of control and crash.

Also, some versions of the F-35 can’t accelerate to supersonic speed without melting their own tails or shedding the expensive coating that helps to give the planes their radar-evading qualities.

The Pentagon’s $400-billion F-35 Joint Strike Fighter program, one of the biggest and most expensive weapons programs in history, has come under fire, so to speak, over more than a decade for delays, rising costs, design problems and technical glitches.
