Not Quite Air Supremacy

US fighter shot down over Iran:
Iran shot down a U.S. fighter jet over the country, U.S. officials and Iranian state-affiliated media said on Friday.
The fate of the plane’s crew was unclear, as American officials scrambled to mount a search and rescue operation before Iran could get to any survivors, officials said.
U.S. Central Command keeps multiple task forces set up near Iran for search and rescue operations in the event that American warplanes are shot down, including in both Iraq and Syria, the officials said. But such an operation is highly difficult because Iran has demonstrated its ability to launch strikes, particularly at slow-moving helicopters that might be involved in such an operation.
War Zone is reporting that it may be an F-15E:
Iran’s armed forces claim that a U.S. fighter jet has been shot down over the country. According to Iranian state media, a U.S. F-35 was downed, although photos of the wreckage of a fighter on the ground point squarely to the aircraft involved being a U.S. Air Force F-15E Strike Eagle — provided they are legitimate.
A spokesperson for Iran’s Khatam al-Anbiya central headquarters said today that an F-35 was brought down over the central part of the country by a new type of air defense system operated by the Islamic Revolutionary Guard Corps (IRGC), with little chance the pilot survived, Reuters reports. The F-15E carries two aircrew, while the F-35 is a single-seater. At this point, we have no firm indication of the fate of the crew if such an incident did indeed take place.
Obviously everything is pending at this point. No idea what’s going to happen in terms of search and rescue, although the US is generally VERY aggressive and risk-acceptant with respect to pilot rescue missions.
