This mission was one of the costliest for the USAAF in the European Theater, with 53 aircraft and 660 air crewmen lost. It was proportionally the most costly major Allied air raid of the war, and its date was later referred to as "Black Sunday". Five Medals of Honor and 56 Distinguished Service Crosses along with numerous others awards went to Operation Tidal Wave crew members. A 1999 research report prepared for the Air War College at Maxwell Air Force Base in Alabama concluded that the mission to Ploiești was "one of the bloodiest and most heroic missions of all time."
