Courtesy of Platz (Japan): The world's first supersonic fighter was the American F-8 Crusader. Development proceeded according to the requirements of the US Navy, and the first flight was successful completed in 1955. Operation started in 1957.
The F-8 Crusader adopted a high wing swept wing design. The wing had a special mechanism that raised the front by 7 degrees. This slight operation succeeded in keeping the distance between takeoffs and landings short. The F-8 demonstrated excellent performance as an on-board fighter operated on an aircraft carrier. The aircraft was equipped with a 18,000 pound thrust engine with an afterburner and was adopted and operated by the US Navy, the Marine Corps, the Philippines, and France.
