The Boeing 747-8 is the final series of the large, long-range wide-body airliners in the Boeing 747 family from Boeing Commercial Airplanes. It is the largest model variant of the 747 and Boeing's largest aircraft overall. Following the introduction of the 747-400, Boeing explored larger 747 versions as potential competitors to the proposed double-deck Airbus A3XX, later developed as the Airbus A380. The stretched aircraft, initially called the 747 Advanced was officially launched as the 747-8 on November 14, 2005, with the designation reflecting its technological ties to the 787 Dreamliner. At the time, Boeing forecasted a market of 300 aircraft.
