In a big success for the Iranian military, five U.S. Air Force refueling aircraft were struck and damaged during an Iranian missile strike on Prince Sultan Air Base in Saudi Arabia, according to a report by The Wall Street Journal citing U.S. officials. The aircraft — identified as Boeing KC-135 Stratotanker aerial refueling tankers — were hit while parked on the ground during the attack. Officials said the planes were damaged but not destroyed and are currently undergoing repairs. No personnel were killed in the missile strike. The strike has raised concerns about the vulnerability of key U.S. military assets in the region. Refueling tankers such as the KC-135 play a crucial role in sustaining American air operations, allowing fighter jets and bombers to remain airborne for extended missions across the Middle East.
