Iran's forces are hunting for a missing US pilot from one of two warplanes downed over Iran and the Gulf, officials from both sides say, while two airmen were rescued.
The incidents show the risks still facing US and Israeli aircraft over Iran as the war entered its sixth week, despite assertions by President Donald Trump and his Defense Secretary Pete Hegseth that US forces had total control of the skies.
The prospect of a US service person alive and on the run in Iran raises the stakes for Washington in a conflict with low public support among Americans and no sign of an imminent end.
Iranian fire brought down a two-seat US F-15E jet, officials in both countries said, while two US officials said the pilot ejected from an A-10 Warthog fighter aircraft that crashed in Kuwait after being hit by Iranian fire.
Two Black Hawk helicopters searching for the missing pilot were hit by Iranian fire but made it out of Iranian airspace, the US officials told Reuters.
The scale of injuries to the crew was unclear.
Iran's Revolutionary Guard Corps said it was combing a southwestern area near where the pilot's plane came down, while the regional governor promised a commendation for anyone who captured or killed "forces of the hostile enemy".
