The Boeing 747-8 is a wide-body airliner developed by Boeing Commercial Airplanes,
the largest variant of the 747. After introducing the 747-400, Boeing considered larger 747 versions as alternatives to Airbus's
proposed Airbus A3XX. The stretched 747 Advanced was launched as the 747-8 on November 14, 2005, for a market forecast of 300 aircraft.

747-8 Super Jumbo (2010)

The Boeing 747-8 is a wide-body jet airliner developed by Boeing Commercial Airplanes. Officially announced in 2005, the 747-8 is the third generation of the 747, with a lengthened fuselage, redesigned wings, and improved efficiency. The 747-8 is the largest 747 version, the largest commercial aircraft built in the United States, and the longest passenger aircraft in the world.

 

The 747-8 is offered in two main variants: the 747-8 Intercontinental (747-8I) for passengers and the 747-8 Freighter (747-8F) for cargo. The first 747-8F performed the model’s maiden flight on February 8, 2010, with the 747-8I following on March 20, 2011. Delivery of the first freighter aircraft occurred in October 2011 and the passenger model began deliveries in 2012. 

Design

As of November 2017, confirmed orders for the 747-8 total 136: 89 of the freighter version, and 47 of the passenger version The 747-8, as the current new development of Boeing’s largest airliner, is notably in direct competition on long-haul routes with the Airbus A380, a full-length double-deck aircraft now in service. For airlines seeking very large passenger airliners, the two have been pitched as competitors on various occasions. Boeing states that the 747-8 is more than 10 percent lighter per seat and is to consume 11 percent less fuel per passenger than the A380, translating into a trip-cost reduction of 21 percent and a seat-mile cost reduction of over 6 percent

In July 2018, there were 110 Boeing 747-8 aircraft in airline service with 
Lufthansa (19), Korean Air (17), Cargolux (14), Cathay Pacific Cargo (14), AirBridgeCargo Airlines (11), UPS Airlines (7), Polar Air Cargo (7), Air China (7), Silk Way West Airlines (5), Atlas Air (3), Qatar Airways Cargo (2), Saudia Cargo (2), Nippon Cargo Airlines (1), and CargoLogicAir (1). Previous operators include Global Supply Systems, a contractor of British Airways.

The 747-8 was designed to be the first lengthened 747 to go into production. The 747-8 and shortened 747SP are the only 747 variants with a fuselage of modified length. The 747-8 was intended to use the same engine and cockpit technology as that of the 787, including the General Electric GEnx turbofan and partial fly-by-wire. Boeing said that the new design would be quieter, more economical, and more environmentally friendly than previous versions of the 747. As a derivative of the already-common 747-400, the 747-8 has the economic benefit of similar training and interchangeable parts. Boeing firmed the 747-8 Freighter’s configuration in October 2006.
