America Is Stuck With a $400 Billion Stealth Fighter That Can’t Fight
Posted by M. C. on June 15, 2019
If during a steep climb the fighters exceed a 20-degree “angle of attack”—the angle created by the wing and the oncoming air—they could become unstable and potentially uncontrollable.

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.
But startling reports by trade publication Defense News on Wednesday revealed flaws that previously only builder Lockheed Martin, the military, and the plane’s foreign buyers knew about.
The newly-exposed problems underscore the potential fragility of American air power as the armed services work to replace more and more old fighters with as many as 2,300 F-35s while also reconfiguring to confront the increasingly deadly Chinese and Russian air forces.
The problems might also help to explain why acting defense secretary Patrick Shanahan reportedly described the F-35 program as “fucked up.”..
One problem cropped up during test flights in 2011, Defense News reported, citing the trove of military documents. In the 2011 tests, at least one F-35B and F-35C both flew at speeds of Mach 1.3 and Mach 1.4. A post-flight inspection in November 2011 revealed the F-35B sustained “bubbling [and] blistering” of its stealth coating.
Further supersonic tests in December 2011 revealed structural damage on an F-35C resulting from the extreme heat coming from the plane’s single Pratt & Whitney engine, one of the most powerful fighter engines ever made.
To avoid similar damage, the military has limited F-35B and F-35C pilots to flying at supersonic speed for less than a minute at a time.
But that could make it impossible for aviators to keep up with, or avoid, Russian and Chinese fighters flying faster than the speed of sound without any restrictions…
But if the program doesn’t apply the fixes before F-35 production picks up, it’s possible the deficiencies will become “baked in” on scores or even hundreds of F-35s. Retroactively fixing deficient jets could cost billions of dollars.
To a great extent, the damage is done. Owing to the Pentagon’s controversial decision to manufacture F-35s while still testing them, Lockheed has delivered around 400 early-model F-35s to the U.S. Air Force, Navy and Marine Corps and to U.S. allies such as the United Kingdom and Israel.
The Air Force, Marines, and Israel have already deployed their F-35s in combat against lightly-armed militant groups.
More than 100 of those early F-35s are B-models that cannot safely fly fast or maneuver hard. They’ll need fixing. It won’t be cheap…
