The Short Version
Only one U.S. military aircraft—an F-15E Strike Eagle—was confirmed shot down over Iranian territory, corroborated by multiple major outlets citing U.S. officials. The second aircraft, an A-10, crashed in the Persian Gulf or Kuwait according to TIME, CBS News, and Air & Space Forces Magazine, and Iran's claim of striking it remains unverified. Describing both as "downed over Iran" materially overstates the geographic scope and certainty of the second incident.
