188-420: A $ 569 million post-tax charge against its fourth-quarter 2015 profits. The chief reason given was that the recovery of the air cargo market had stalled, resulting in slowed demand for the 747 freighter. Boeing cited the 747-8F as the main driver behind potential future 747-8 orders. To help reduce production costs in the meantime and maintain the 747 production line's viability, the company plans to integrate
282-549: A 2% lower fuel burn. Boeing also improved the tail fuel tank's function and improved the flight management software. Aircraft produced beginning in 2014 weigh 9,000 lb (4.1 t) less than the first 747-8 coming off the production line and burn 3.5% less fuel. Other improvements include revised fairings next to the tail and wing-to-body-fairings. The chevrons on the trailing edge of the GEnx-2B nacelle were made thinner. Boeing hoped that these improvements, which benefit both
376-409: A 747-8F proved the variant's capability by taking off from the runway at Victorville, California weighing 1,005,000 pounds (455,860 kg). Its design maximum take-off weight (MTOW) is 975,000 pounds (442,253 kg). The fifth 747-8F joined the flight-test effort with its first flight on February 3, 2011. On September 30, 2010, Boeing announced a further postponement, with the delivery of
470-505: A 747-8F, was delivered to Atlas Air on January 31, 2023. Boeing had considered larger-capacity versions of the 747 several times during the 1990s (such as the Boeing New Large Airplane ) and 2000s. The 747-500X and -600X, announced at the 1996 Farnborough Airshow , would have stretched the 747, but they did not attract enough interest to enter development. At the same air show, a hypothetical wider-bodied 747-700X
564-400: A 747-8I was US$ 418.4M and a 747-8F US$ 419.2M. By early 2019, the backlog and production rates were sufficient to sustain production until late 2022. On July 2, 2020, media reports stated that Boeing intended to end 747 production in 2022 after the 16 outstanding orders had been built and delivered. The demand for four-engine airliners had been flat for several years, with most orders going to

Before they could be delivered, the company filed for bankruptcy and was closed down; the two aircraft were stored at Southern California Logistics Airport in the Mojave Desert to prevent corrosion. On 27 February 2018, the White House announced a US$ 3.9 billion (~$ 4.66 billion in 2023) agreement with Boeing to modify the two unsold 747-8s to replace the current VC-25As. The new aircraft will be designated VC-25B. These aircraft are to be retrofitted with telecommunications and security equipment to bring them to
846-536: A US$ 1-billion charge against its earnings for this delay. In response, launch customer Cargolux stated it still intended to take delivery of the thirteen freighters it had ordered; Lufthansa confirmed its commitment to the passenger version. On November 12, 2009, Boeing announced that Cargolux's first airplane was fully assembled and entering the Everett plant's paint shop. It was to undergo flight testing prior to delivery. On December 4, 2009, Korean Air became

While keeping its basic structure and sweep, the wing is thicker and deeper, holding more fuel, and wider with raked wingtips . Powered more efficiently than preceding 747s by a smaller version of the General Electric GEnx turbofan from the 787 Dreamliner , its maximum take-off weight (MTOW) grew to 975,000 pounds (442 t),
2444-460: Is the final series of the large, long-range wide-body airliners in the Boeing 747 family from Boeing Commercial Airplanes . The 747-8 is the largest variant of the 747 and Boeing 's largest aircraft. After introducing the 747-400 , Boeing considered larger 747 versions as alternatives to the proposed double-deck Airbus A3XX, later developed as the Airbus A380 . The stretched 747 Advanced
2538-476: The Air Force One designation applies to the aircraft only while the president is on board, the term is commonly used to refer to the VC-25 in general. The two aircraft often operate in conjunction with Marine One helicopters, which ferry the president to airports whenever a vehicle motorcade would be inappropriate. Two new aircraft, based on the Boeing 747-8I and designated VC-25B, have been ordered by
2632-446: The Airbus A380 , a full-length double-deck aircraft introduced in 2007. 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 consumes 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. Production of

The VC-25s were completed in 1986 and first flew in 1987. The interior designs were created by First Lady Nancy Reagan , who used designs reminiscent of the American Southwest . Problems with interior wiring for communication systems delayed delivery of
2820-636: The International Air Transport Association noted that slower economic growth, following the Great Recession of 2008, had led to lower demand for air freighters. The world's air cargo fleet in 2012 was smaller than it was in 2003. However, the proportion of very large freighters in that fleet has increased, and Boeing's dominant position in large, fuel-efficient freighters has offered the company an opportunity to protect its market share and its product line despite

On October 27, 2016, UPS Airlines announced an order for 14 747-8Fs with options for an additional 14. The 14 options were then converted to official orders on February 1, 2018. Deliveries are scheduled from 2017 through 2022. On September 7, 2017, it was reported that Turkish Airlines is in negotiations with Boeing for purchasing 8 747-8Is to strengthen its widebody fleet. In 2019, list-price unit cost of
3196-464: The 747 and 767 production lines more closely with each other. Boeing expected the cargo market to improve by mid-2019 and were planning to increase the 747's production rate back to 1/month from then on. However, in July 2016, this production rate increase was cancelled, i.e. 747 production remained at 0.5 per month. At the same time, the company announced another after-tax charge of $ 814 million, reflecting
3290-410: The 747-400, the -8I was to be 16% more fuel-efficient, have 13% lower seat-mile costs with nearly the same cost per trip, and have a 30% smaller noise footprint area. Boeing stated that the 747-8I was the world's fastest commercial jet. For the 747-8, Boeing proposed some changes to the interior layout of the aircraft. The -8I's upper deck is lengthened compared to the 747-400. Most noticeable are
3384-491: The 747-8 a Category F size airplane rather than Category E size, similar to the Airbus A380. Raked wingtips , similar to the ones used on the 777-200LR, 777-300ER, and 787 aircraft, are used on the 747-8 instead of winglets used on the 747-400. These wingtip structures help reduce the wingtip vortices at the lateral edges of the wings, decreasing wake turbulence and drag and thereby improving fuel efficiency. Another effort to increase efficiency (through weight savings)
3478-451: The 747-8 project. Chief executive Jim McNerney stated that continuation of the project was not a foregone conclusion, and that the company was assessing various options. On July 21, 2009, Boeing released a photograph of the first cargo airplane, its fuselage and main wing assembled. In October 2009, Boeing announced that it had delayed the first flight on the 747-8 until the first quarter of 2010 and delayed 747-8I delivery. The company took
3572-426: The 747-8I's appearance. Analysts do not see bright prospects for very large aircraft—those with more than 400 seats—whose orders have slowed in the mid-2010s, since there are widebody twinjets with similar range and greater fuel efficiency, giving airlines more flexibility at a lower upfront cost. Volga-Dnepr Airlines signed a memorandum of understanding (MoU) with Boeing for the purchase of 20 more 747-8Fs at
3666-468: The 747X program, Boeing continued to study improvements to the 747. The 747-400XQLR (Quiet Long Range) was meant to have an increased range of 8,056 nmi (14,920 km; 9,271 mi), with better fuel efficiency and reduced noise . Changes studied included raked wingtips similar to those used on the 767-400ER and a ' sawtooth ' engine nacelle for noise reduction. Although the 747-400XQLR did not move to production, many of its features were used for
3760-660: The Air Force posted online an amendment to its Air Force One contract authorizing Boeing to begin preliminary design activities. This version of the contract synopsis confirmed that the government will buy two modified 747-8 aircraft. Boeing was awarded a contract in January 2016 to identify cost reduction opportunities in areas including maintenance, aerial refueling and communications. On 15 July 2016, Boeing received another contract for pre-engineering and manufacturing development (EMD) risk-reduction to address "system specification,
3854-423: The Boeing 777-300ER. The future for the 747-8 passenger version appears limited. Airlines bought the original 747 primarily for its range, not its capacity. The advent of long-range twin-engine jets, notably Boeing's own 777, took away the 747's range advantage. Compared to the 747-8I, the upcoming 777-9X "mini-jumbo jet" is projected to have a lower fuel cost per seat mile and greater cargo capacity, though it has

The VC-25As have also been used to transport deceased former presidents, as the guest area aft of "the White House" has chairs and tables that can be removed and the casket laid in their place. The bodies of Ronald Reagan, Gerald Ford , and George H.W. Bush were transported to Washington for their state funerals, and then on to their final resting places. Colonel Mark Tillman, pilot for President George W. Bush, said, "We'll take care of
4700-643: The aircraft. By the end of June 2010, the three 747-8Fs that composed the flight-test program had flown a total of over 500 hours and had completed hot-weather testing in Arizona. In June 2010, Boeing determined that a fourth −8F aircraft was needed to help complete flight testing. It was decided to use the second production aircraft, RC503, to conduct the non-instrumented or minimally-instrumented tests, such as HIRF and Water Spray Certifications. The aircraft, painted in delivery customer Cargolux 's new livery, first flew on July 23, 2010. On August 21, 2010,

The Biden administration abandoned the new design, citing "additional engineering, as well as increased time and cost." A modified version of the traditional scheme was announced in March 2023. The 747s began undergoing modification work at Boeing's San Antonio facility in 2020. According to The Wall Street Journal ,
5546-686: The first freighter to Cargolux planned for mid-2011. The 747-8 passenger version took to the skies over Everett, Washington, for the first time on March 20, 2011. The second 747-8I flew on April 26, 2011. Three 747-8 Intercontinentals had taken part in flight testing by December 2011. The 747-8F received its amended type certificate jointly from the Federal Aviation Administration (FAA) and European Aviation Safety Agency (EASA) on August 19, 2011. Freighter deliveries were to begin on September 19, 2011. Then, on September 17, 2011, Cargolux announced that it would not accept
