Despite the WTO ruling there will always be some who claim that US planemakers are unsubsidised, based on financials alone and ignoring all the other ways a government can support its domestic industries. The USAF could be operating a fleet of highly capable Airbus tankers by now were it not for the politically-driven switch to an inferior Boeing product. (Yes, the KC30 exceeded the requirements by some margin, but it works. How much of the cost difference has now been poured into fixing the KC46?) Plenty of European nations operate US military kit but you’d be hard pressed to find many examples of the reverse. This is subsidy by another name. And as for the savings Boeing made on design and certification of a new aircraft with FAA (= US Government) complicity in the 737MAX saga, well, that was going pretty well until the crashes. I’m not saying Europe is innocent, by the way: clearly it’s not. But enough already with protestations of US free market purity.
