At least 16 US military aircraft have been lost since the start of the war with Iran, including 10 Reaper strike drones hit by enemy fire and a half-dozen other planes badly damaged in attacks or accidents.

The most serious losses were because of accidents: three US F-15s downed by friendly fire in Kuwait, and a KC-135 tanker destroyed during a refueling operation. All six crew members on the tanker were killed in the accident.
