The Boeing 747-8 is the last member of the Boeing 747 family, a series of large, long-range wide-body airliners built by Boeing Commercial Airplanes. It is the largest model 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 forecast a market of 300 aircraft.
