BOEING 747 AIRCRAFT AIRLINER FACTS, DATES, PICTURES
AND HISTORY FOR ALL BOEING 747 VARIANTS
NEW BOEING 747-8 INTERCONTINENTAL

The 747-100 was the original variant launched in 1966. The 747-200 soon followed, with an order in 1968. The 747-300 was launched in 1980 and was followed in 1985 by the 747-400. Lastly, the 747-8 was announced in 2005. Several versions of each variant have been produced. Many of the early variants were in production simultaneously.

747-100

The first 747-100s were built with six upper-deck windows (three per side) to accommodate upstairs lounge areas. Later, as airlines began to use the upper-deck for premium passenger seating instead of lounge space, Boeing offered a 10-window upper deck as an option. Some -100s were retrofitted with the new configuration.

No freighter version of this model was developed by Boeing. However, 747-100s have been converted to freighters. A total of 167 747-100s were built.

A 747-100B version, which has a stronger airframe and undercarriage design as well as an increased maximum takeoff weight (MTOW) of 750,000 lb (340,000 kg) was offered. The 747-100B was delivered only to Iran Air and Saudia (now Saudi Arabian Airlines). Optional engine models were offered by Rolls-Royce (RB211) and GE (CF6), but only Saudia ordered the Rolls-Royce option. A total of nine 747-100Bs were built.

747-100SR

Responding to requests from Japanese airlines, Boeing developed the 747-100SR as a "short range" variant of the 747-100. The SR has a lower fuel capacity but can carry more passengers, up to 498 in early versions and more than 550 in later models, because of increased economy class seating. The 747SR has a modified body structure to accommodate the added stress accumulated from a greater number of takeoffs and landings. The -100SR entered service with Japan Airlines (then Japan Air Lines) on October 7, 1973. Specifically, the SR has extra structural support at the wings, fuselage, and the landing gear along with a 20% reduction in fuel capacity. Later, short range versions of the -100B and the -300 were also developed. The SRs are used primarily on domestic flights in Japan.

Two 747-100SRs were delivered to Japan Airlines with a stretched upper deck to accommodate more passengers. This modification is known as the "SUD" (stretched upper deck). A total of 29 747-100SRs were built.

All Nippon Airways (ANA) operated 747-100SRs on domestic Japanese routes with 455 or 456 seats but retired the last aircraft on 10 March 2006. JAL operated the 747-100B/SR/SUD variant with 563 seats on domestic routes, and retired these planes in the third quarter of 2006.

747SP

The idea for the 747SP came from a joint request between Pan American World Airways and Iran Air who were looking for a high capacity airliner with enough range to cover Pan Am's New York–Middle Eastern routes and Iran Air's planned Tehran-New York route. The Tehran-New York route when launched was the longest non-stop commercial flight in the world. The 747SP is 48 feet 4 inches (14.73 m) shorter than the 747-100. Except for the planned 747-8, the SP is the only 747 with a fuselage of modified length. Fuselage sections were eliminated fore and aft of the wing, and the center section of the fuselage was redesigned. Single-slotted flaps replaced the complex triple-slotted Fowler flaps of the 100 series. The under-wing "canoes", which housed the flap mechanisms on full-size 747s, were eliminated entirely on the SP. The 747SP, compared to earlier variants, had a tapering of the aft upper fuselage into the empennage, a double-hinged rudder, and longer vertical and horizontal stabilizers.

The 747SP was granted a supplemental certificate on 4 February 1976 and entered service with Pan Am, the launch customer and Iran Air, that same year. The aircraft was chosen by airlines wishing to serve major airports with short runways.

A total of 45 747SPs were built. The 44th 747SP was delivered on August 30, 1982. Boeing re-opened the 747SP production line to build one last 747SP five years later in 1987 for an order by the United Arab Emirates government. In addition to airlines use, one 747SP was modified for NASA Dryden Flight Research Center's SOFIA experiment.

747-200

The 747-200 has more powerful engines, higher takeoff weights (MTOW) and range than the -100. A few early -200s retained the three-window configuration of the -100 on the upper deck, but most were built with a 10-window configuration on each side.

Several versions in addition to the -200 were produced. The 747-200B is an improved version of the 747-200, with increased fuel capacity and more powerful engines; it first entered service in February 1971. The -200B aircraft has a full load range of about 6,857 nmi (12,700 km). The 747-200F is the freighter version of the -200 model. It could be fitted with or without a side cargo door. It has a capacity of 105 tons (95.3 tonnes) and an MTOW of up to 833,000 lb (378,000 kg). It entered first service in 1972 with Lufthansa. The 747-200C Convertible is a version that can be converted between a passenger and a freighter or used in mixed configurations.The seats are removable, and the model has a nose cargo door. The -200C could be fitted with an optional side cargo door on the main deck.

The 747-200M is a combination version that has a side cargo door on the main deck and can carry freight in the rear section of the main deck. A removable partition on the main deck separates the cargo area at the rear from the passengers at the front. This model can carry up to 238 passengers in a 3-class configuration if cargo is carried on the main deck. The model is also known as the 747-200 Combi. As on the -100, a stretched upper deck (SUD) modification was later offered. A total of 10 converted 747-200s were operated by KLM. Union des Transports Aériens (UTA) also had two of these aircraft converted.

A total of 393 of the 747-200 versions had been built when production ended in 1991. Of these, 225 were 747-200s, 73 were 747-200F, 13 were 747-200C, 78 were 747-200M, and 4 were military. Many 747-200s are still in operation, although most large carriers have retired them from their fleets and sold them to smaller operators. Large carriers have sped up fleet retirement following the September 11th attacks and the subsequent drop in demand for air travel, scrapping some or turning others into freighters.

747-300

The most visible difference between the -300 and previous models was a stretched upper deck with two new emergency exit doors and an optional flight-crew rest area immediately aft of the flight deck as standard. (The stretched upper deck had previously been offered as a retrofit and first appeared on two Japanese 747-100 SR models.) Compared to the -200, the upper deck is 23 feet 4 inches (7.11 m) longer than the -200. A new straight stairway to the upper deck instead of a spiral staircase is another difference between the -300 and earlier variants. The staircase creates room below and above for more seats. With minor aerodynamic changes, Boeing increased the cruise speed of the -300 to Mach 0.85 from Mach 0.84 on the -100/-200. The -300 features the same takeoff weight. Two of the three engine choices from the -200 were unchanged in the -300, but the General Electric CF6-80C2B1 was offered instead of the CF6-50E2 offered on the -200.

The 747-300 name, which was proposed for a variant that was never launched, was revived for this new version, which was introduced in 1980. Swissair ordered the first 747-300 on 11 June 1980. The 747-300 first flew on 5 October 1982. Swissair was the first customer to accept delivery on March 23, 1983.

In addition to the passenger version, other versions were available. The 747-300M has cargo capacity in the rear portion of the main deck similar to the -200M, but with the stretched upper deck it can carry more passengers.The 747-300SR is a short range version to meet the need for a high-capacity domestic model. Japan Airlines operated such aircraft with more than 600 seats on the Okinawa–Tokyo route and elsewhere. Boeing never launched a newly built freighter version of the 747-300, but it modified used passenger -300 models into freighters starting in 2000.

A total of 81 aircraft were delivered, 56 for passenger use, 21 -300M and 4 -300SR versions. The 747-300 was soon superseded by the launch of the more advanced 747-400 in 1985, just two years after the -300 entered service. The last 747-300 was delivered in September 1990 to Sabena.

Today, many -300 aircraft are still active, despite a significant loss of interest in the series among large carriers who replaced the 747-300 with the 747-400. Air France, Air India, Pakistan International Airlines and Qantas were some of the last major carriers to operate the 747-300. On 29 December 2008, Qantas flew its last scheduled 747-300 service, operating from Melbourne to Los Angeles via Auckland. On 20 January 2009, Qantas' last 747-300 was flown to the United States for storage. Although none were constructed as dedicated freighters, some -300s have been converted to cargo operations.

747-400

The 747-400 is an improved model with increased range. It has wing-tip extensions of 6 ft (1.8 m), winglets of 6 ft (1.8 m), which improve the 747-400's fuel efficiency by 4% compared to previous 747 versions. It has a new glass cockpit designed for a flight crew of two instead of three. The use of electronics reduced the number of dials, gauges and knobs from 971 to 365. It has tail fuel tanks, revised engines and a new interior. The longer range was used by some airlines to bypass traditional fuel stops, such as Anchorage. The -400 was offered in passenger (400), freighter (400F), combi (400C), domestic (400D), extended range passenger (400ER) and extended range freighter (400ERF) versions. The freighter version does not have an extended upper deck. The 747-400D was built for short range operations and does not include winglets, but these can be retrofitted.

The passenger version first entered service in February 1989 with Northwest Airlines on the Minneapolis to Phoenix route. The combi version entered service in September 1989 with KLM. The freighter version entered service in November 1993 with Cargolux. The 747-400ERF entered service in October 2002 and the 747-400ER entered service the following month with Qantas, the only airline ever to order the passenger version. Some of the last built Boeing 747-400s were delivered with Dreamliner livery along with the modern interior from the Boeing 777.

In January 2004 Boeing and Cathay Pacific launched the Boeing 747-400 Special Freighter program, later referred to as the Boeing Converted Freighter (BCF). The first 747-400BCF was redelivered in December 2005.

The last passenger version of the 747-400 was delivered in April 2005 to China Airlines. Boeing announced in March 2007 that it had no plans to produce further passenger versions of the -400. However, orders for 36 -400F and -400ERF freighters were already in place at the time of the announcement. As of June 2009, 692 of the 747-400 series aircraft had been delivered with two aircraft (-400ERFs) to be delivered.

At various times, the largest operator of the 747-400 has been Singapore Airlines, Japan Airlines, or British Airways.

747 LCF Dreamlifter
Boeing 747 Large Cargo Freighter, also called Dreamlifter, is modified from 747s previously in airline use.

The 747-400 Dreamlifter (originally called the 747 Large Cargo Freighter or LCF) is a Boeing-designed modification of existing 747-400s to a larger configuration to ferry Boeing 787 sub-assemblies to the Boeing plant in Everett, Washington, for final assembly. Evergreen Aviation Technologies Corporation is completing modifications of 747-400s into Dreamlifters in Taiwan. The aircraft flew for the first time on September 9, 2006. The Dreamlifter's only intended purpose is to transport sub-assemblies for the Boeing 787.The aircraft is certified to carry only essential crew and not passengers. Three aircraft have been built, and one on order.

747-8

Boeing announced a new 747 variant, the 747-8 (referred to as the 747 Advanced prior to launch) on 14 November 2005. The variant will use the same engine and cockpit technology as the 787, hence the use of the "8". Plans call for the new design to be quieter, more economical and more environmentally friendly. The 747-8's fuselage was stretched from 232 to 251 feet (70.8 to 76.4 m). When the 747-8 enters service, it will surpass the Airbus A340-600 as the world's longest airliner.

The passenger version, dubbed 747-8 Intercontinental or 747-8I, will be able to carry up to 467 passengers in a 3-class configuration and fly more than 8,000 nmi (15,000 km) at Mach 0.855. As a derivative of the already common 747-400, the 747-8 has the economic benefit of similar training and interchangeable parts. The 747-8I is scheduled to enter service in 2010.

Boeing 747-8 freighter

Also offered is the 747-8 Freighter or 747-8F, which derives from the 747-400ERF. The 747-8F can accommodate 154 tons (140 tonnes) of cargo. To aid loading and unloading, it features an overhead nose-door. It has 16 percent more payload capacity than the 747-400F and can hold seven additional standard air cargo containers. The 747-8F is scheduled to enter service in 2009.

Several units are under construction at Boeing's Everett facility. The 747-8 has received a total of 105 orders with 78 for the -8F and 27 for the -8I as of June 2009.

Government, military and other variants

20-1101 Japanese Air Force One, one of the two customized Boeing 747-400s that have been part of the Japan Air Self-Defense Force since 1993

* C-19 – The U.S. Air Force gave this designation to the 747-100s used by some U.S. airlines and modified for use in the Civil Reserve Airlift Fleet.
* VC-25 – This aircraft is the U.S. Air Force Very Important Person (VIP) version of the 747-200B. The U.S. Air Force operates two of them in VIP configuration as the VC-25A. Tail numbers 28000 and 29000 are popularly known as Air Force One, which is technically the air-traffic call sign for any United States Air Force aircraft carrying the U.S. President. Although based on the 747-200B design, they include several innovations introduced on the 747-400. Partially completed aircraft from Everett, Washington, were flown to Wichita, Kansas, for final outfitting.
* E-4B – Formerly known as the National Emergency Airborne Command Post (referred to colloquially as "Kneecap"), this aircraft is now referred to as the National Airborne Operations Center (NAOC).
* YAL-1 – This is the experimental Airborne Laser, a component of the National Missile Defense plan.
* Shuttle Carrier Aircraft – Two 747s were modified to carry the Space Shuttle. One is a 747-100 (N905NA) and the other is a 747-100SR (N911NA). A SCA carried the Space Shuttle Enterprise in the late 1970s, and has since carried all Space Shuttles.
* A number of other governments also use the 747 as a VIP transport, including Bahrain, Brunei, India, Iran, Japan, Kuwait, Oman, Pakistan, Qatar, Saudi Arabia and United Arab Emirates. Several new Boeing 747-8s have been ordered by Boeing Business Jet for conversion to VIP transport for several unidentified customers.
* C-33 – This aircraft was a proposed U.S. military version of the 747-400 intended to augment the C-17 fleet. The plan was canceled in favor of additional C-17 military transports.
* KC-33A – A proposed 747 was also adapted as an aerial refueling tanker and was bid against the DC-10-30 during the 1970s Advanced Cargo Transport Aircraft (ACTA) program that produced the KC-10A Extender. Before the Khomeini-led revolution, Iran bought four 747-100 aircraft with air-refueling boom conversions to support a fleet of F-4 Phantoms. It is unknown whether these aircraft remain usable as tankers. Since then, other proposals have emerged for adaptation of later 747-400 aircraft for this role.
* 747 CMCA – This variant was considered by the U.S. Air Force as a Cruise Missile Carrier Aircraft during the development of the B-1 Lancer strategic bomber. It would have been equipped with 50 to 100 AGM-86 ALCM cruise missiles on rotary launchers. This plan was abandoned in favor of more conventional strategic bombers.
* Evergreen 747 Supertanker - A Boeing 747-200 modified as an aerial application platform for fire fighting using 20,000 US gallons (76 m3) of firefighting chemicals. Evergreen International Airlines were issued with a supplementary type certificate for the Boeing 747-200C (ST0192LA) in October 2006 for the installation and removal of internal tanks, associated systems and support structure for the aerial dispersant of liquids.

Undeveloped 747 variants

Boeing has studied a number of 747 variants that have not gone beyond the concept stage.
747-300 trijet

During the 1970s, Boeing studied the development of a shorter body, three-engine 747 to compete with the smaller L-1011 TriStar and DC-10, which had lower trip costs than the 747SP. The 747-300 trijet would have had more payload, range and passenger capacity. The center engine would have been fitted in the tail with an S-duct intake similar to the L-1011's. However, engineering studies showed that a time-consuming and costly redesign of the 747 wing would be necessary. In the 1990s, the Boeing 777, a long range twinjet airliner smaller than the 747-400 entered service in the market where the 747-300 had been targeted.

Boeing announced the 747-500X and -600X at the 1996 Farnborough Airshow. The proposed models would have combined the 747's fuselage with a new 251 ft (77 m) span wing derived from the 777. Other changes included adding more powerful engines and increasing the number of tires from two to four on the nose landing gear and from 16 to 20 on the main landing gear.

The 747-500X concept featured an 18 ft (5.5 m) stretch to 250 ft (76.2 m) long, and the aircraft was to carry 462 passengers over a range up to 8,700 nautical miles (10,000 mi, 16,100 km), with a gross weight of over 1.0 Mlb (450 Mg). The 747-600X concept featured a greater stretch to 279 ft (85 m) with seating for 548 passengers, a range of up to 7,700 nmi (8,900 mi, 14,300 km), and a gross weight of 1.2 Mlb (540 Mg). A third study concept, the 747-700X, would have combined the wing of the 747-600X with a widened fuselage, allowing it to carry 650 passengers over the same range as a 747-400. The cost of the changes from previous 747 models, in particular the new wing for the 747-500X and -600X, was estimated to be more than $5 billion. Boeing was not able to attract enough interest to launch the aircraft.

747X and 747X Stretch

As Airbus progressed with its A3XX study, Boeing in 2000 offered the market a 747 derivative as an alternative. This was a more modest proposal than the previous -500X and -600X that would retain the 747's overall wing design and add a segment at the root, increasing the span to 229 ft (69.8 m). Power would have been supplied by either the Engine Alliance GP7172 or the Rolls-Royce Trent 600, which were also proposed for the 767-400ERX.A new flight deck based on the 777's would be used. The 747X aircraft was to carry 430 passengers over ranges of up to 8,700 nmi (10,000 mi, 16,100 km). The 747X Stretch would be extended to 263 ft (80.2 m) long, allowing it to carry 500 passengers over ranges of up to 7,800 nmi (9,000 mi, 14,500 km). Both would feature an interior based on the 777's signature architecture. Freighter versions of the 747X and 747X Stretch were also studied.

Like its predecessor, the 747X family was unable to garner enough interest to justify production, and it was shelved along with the 767-400ERX in March 2001, when Boeing announced the Sonic Cruiser concept. Though the 747X design was less costly than the 747-500X and -600X, it was criticized for not offering a sufficient advance from the existing 747-400. The 747X did not make it beyond the drawing board, but the 747-400X being developed concurrently moved into production to become the 747-400ER.

747-400XQLR

After the end of the 747X program, Boeing continued to study improvements that could be made to the 747. The 747-400XQLR (Quiet Long Range) was meant to have an increased range of 7,980 nmi (9,200 mi, 14,800 km), with improvements to boost efficiency and reduce noise. Improvements 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 the 747 Advanced, which has now been launched as the 747-8.

THE NEW BOEING 747-8 INTERCONTINENTAL

The 747-8 Intercontinental and 747-8 Freighter use 787 technologies to significantly improve the economics and functionality of the 747-8 - all while improving fuel efficiency and reducing emissions and noise.

New wing design, next generation GEnx engines, a modern flight deck and new materials are just some of the ways the new 747-8 benefits from the breakthrough technologies of the 787.
