U.S. defense chiefs have made little progress in fixing technical problems with their new F-35 all-weather stealth combat jets, according to a report by a Washington-based anti-corruption body.
The F-35 program is led by the U.S., though jets are typically assembled by NATO and other allies that have bought the single-seat fighters, including Britain, Italy, Australia, Canada, Norway and Denmark.
Washington kicked Turkey out of the F-35 program last year after Ankara struck a deal to buy the Russian S-400 surface-to-air missile system, which could have risked some of the fighter’s stealth secrets falling into Russian hands.
