Was the F-117 created by taking Soviet stealth research?
Short answerPublished Soviet theory was an important input, but American computing and broader engineering work were needed to turn it into an aircraft.
NotesThe answer rejects the simple claim that the United States stole a finished Soviet stealth design. Soviet mathematical work on radar reflection was published because its practical application appeared doubtful. American engineers had enough computing power to turn those equations into a flyable faceted shape, while also drawing on other domestic research and development. The example shows how openly available theory can acquire strategic value when another institution has the tools and programme structure needed to apply it.
