The Boeing 7478 is a widebody jet airliner developed by Boeing Commercial Airplanes. Officially announced in 2005, the 7478 is the fourthgeneration Boeing 747 version, with lengthened fuselage, redesigned wings and improved efficiency. The 7478 is the largest 747 version, the largest commercial aircraft built in the United States, and the longest passenger aircraft in the world.[4]
The 7478 is offered in two main variants: the 7478 Intercontinental (7478I) for passengers and the 7478 Freighter (7478F) for cargo. The first 7478F performed the model's maiden flight on February 8, 2010 with the 7478 Intercontinental following on March 20, 2011. In October 2011, confirmed orders for the 7478 totaled 111, including 75 of the freighter version, and 36 of the passenger version. Delivery of the first freighter aircraft was delayed before occurring in October 2011; passenger model deliveries are to begin in 2012.
