It says right in the article ~200 a year. The base scenario in recent war games, the US lost 270 aircraft total, of which 206 were USAF. Japan lost 112, Taiwan's air force effectively ceased to exist. Across iterations, Air Force losses ranged from 168 to 372(mostly on the ground)in a fight with China over Taiwan. Those are substantial losses but assuming all the losses were f35(they were not) even at current non wartime production rates the United States could replace that in a few years time.
Also the war games showed that when LRASM supplies were depleted, the f35 became the primary anti ship and strike asset as it was one of the few aircraft that could fulfill the role and survive.
