The F-35 is a symbol of U.S. military and technological might. It is also reliant for more than 80 parts on a little-known company based in a quiet Danish suburb.
Overall, the jet fighter, made by Lockheed Martin, has more than 1,900 suppliers from about a dozen countries that provide everything from tiny chip boards to the ejector seat.
The F-35’s sprawling supply chain is one example of how even the U.S. defense industry, which exports billions of dollars worth of weapons while importing few in return, could be challenged by the Trump administration’s sweeping trade policies.
