Boeing 747 Dreamlifter (LCF) — Outsize-cargo airliner sub-assembly ferry

The Boeing 747 Dreamlifter (designated 747-400 Large Cargo Freighter / LCF) is an outsize-cargo derivative of the 747-400 airliner, built by Boeing to ferry 787 Dreamliner sub-assemblies between supplier factories in Japan, Italy, and the United States. Four airframes were converted from used 747-400 airliners by Evergreen Aviation Technologies in Taiwan between 2006 and 2010. First flight came on 9 September 2006. As of 2026 all four Dreamlifters remain active in the Atlas Air-operated Boeing fleet, ferrying 787 wing pairs, fuselage barrels, and horizontal stabilisers across roughly 4,500 nm Pacific and Atlantic legs.

The conversion was dramatic. Each donor 747-400 was stripped of its passenger cabin and main deck floor; a much larger upper fuselage was grafted on top, expanding the cargo cross-section to about 65,000 ft³ (1,840 m³) — roughly 3× the standard 747-400F freight capacity. Cargo loads through a hinged tail-cone ("swing-tail") that pivots up and to one side on hydraulic hinges, exposing the entire rear of the hold for roll-on/roll-off loading. Wings, engines, and main landing gear remain standard 747-400 airframe components.

The Dreamlifter solves a Boeing-specific 787 production problem. The 787 Dreamliner's sub-assemblies are built across a global supply chain — wings by Mitsubishi Heavy Industries in Nagoya, fuselage forward sections by Spirit AeroSystems in Wichita, fuselage barrels by Alenia Aeronautica in Italy, horizontal stabilisers by Korea Aerospace Industries — and final assembly happens at Boeing's Everett, Washington, and Charleston, South Carolina, plants. Without the Dreamlifter the supply-chain trip times by sea would add about 30 days to each 787 production cycle. With the Dreamlifter the same trips take 18-30 hours in the air.

The Dreamlifter is operated under contract by Atlas Air Worldwide for Boeing. The fleet flies a regular schedule between Mitsubishi Nagoya, KAI Sacheon, Alenia Grottaglie, Spirit AeroSystems Wichita, and the Boeing 787 final-assembly lines. Each Dreamlifter is registered in the U.S. (N249BA, N718BA, N747BC, N780BA). The type's only competitor in the outsize-airliner-sub-assembly niche is the Airbus Beluga family, which serves the equivalent role for Airbus airliner production in Europe.

For Kids — a shorter, friendlier version

The Boeing 747 Dreamlifter is a very special cargo plane. It carries giant airplane parts from one factory to another. Boeing built it to move pieces of the 787 Dreamliner jet.

Workers took old 747 passenger planes and changed them completely. They removed the seats and added a much bigger, rounder body on top. This gave the plane a huge space inside to hold cargo. Four of these planes were made between 2006 and 2010.

The Dreamlifter's hold is bigger than three regular cargo 747s combined. That makes it larger than almost any other cargo space in the sky. It can carry whole wing pairs, fuselage barrels, and tail parts from factories in Japan, Italy, and the United States.

Loading the plane is done in a very cool way. The entire tail swings open like a giant door. Parts roll straight in through the back. Then the tail swings shut and the plane is ready to fly.

All four Dreamlifters are still flying today. They make long trips across the Pacific and Atlantic oceans. Without them, building the 787 Dreamliner would be much harder.

Fun Facts

  • The Dreamlifter's cargo hold is larger than three standard 747 cargo planes put together.
  • The tail of the plane swings open on hydraulic hinges to load giant airplane parts.
  • Four Dreamlifters were built by converting old 747 passenger jets in Taiwan.
  • The first Dreamlifter took flight on September 9, 2006.
  • It carries 787 Dreamliner wings, fuselage sections, and tail parts across the ocean.
  • The plane flies routes longer than 4,500 nautical miles over the Pacific and Atlantic.
  • The wings, engines, and landing gear are the same as a regular 747-400.

Kids’ Questions

What does the Dreamlifter carry?

The Dreamlifter carries big parts for the 787 Dreamliner jet. These parts include wing pairs, fuselage barrels, and tail sections. They come from factories in Japan, Italy, and the United States.

How do you load things into the Dreamlifter?

The tail of the plane swings open like a huge door. Parts are rolled right into the back of the plane. Then the tail swings shut and the plane is ready to go.

How many Dreamlifters were made?

There are four Dreamlifters in total. They were all made between 2006 and 2010. All four are still flying today.

Was the Dreamlifter built from scratch?

No, it was not built from scratch. Workers took old 747 passenger jets and changed them. They removed the cabin and added a much bigger body on top to hold large cargo.

Variants

747-400LCF Dreamlifter (4 airframes)
Single production configuration. Four converted from used 747-400 passenger airliners by Evergreen Aviation Technologies (Taiwan) between 2006 and 2010. Registrations N249BA, N718BA, N747BC, N780BA. ~65,000 ft³ hold; PW4062 turbofans; 803,000 lb MTOW.

Notable Operators

Atlas Air Worldwide (under Boeing contract)
Sole operator. Atlas Air provides crews and maintenance under a long-term contract from Boeing. The four-aircraft fleet flies daily rotations between 787 supplier sites in Japan, Korea, Italy, and the United States.
Boeing
Owner of the fleet. Boeing pays Atlas Air for transport services and uses the Dreamlifters exclusively for 787 production-line sub-assembly ferry. The aircraft are not available for general charter.

Frequently Asked Questions

What does the Boeing 747 Dreamlifter carry?

787 Dreamliner sub-assemblies — wings from Mitsubishi Heavy Industries (Nagoya, Japan), fuselage barrels from Alenia Aeronautica (Grottaglie, Italy), fuselage forward sections from Spirit AeroSystems (Wichita, Kansas), and horizontal stabilisers from Korea Aerospace Industries (Sacheon). The Dreamlifter is dedicated to Boeing 787 production and does not carry general freight.

How does the Dreamlifter load cargo?

The entire tail cone hinges upward and to one side on hydraulic hinges, exposing the rear of the cargo hold for roll-on/roll-off loading. The mechanism is unique to the Dreamlifter; the standard 747-400F uses side and nose loading only.

How big is the Dreamlifter compared with the 747-400?

Length 235 ft (about 4 ft longer than 747-400). Wingspan 211 ft (same as 747-400). The big difference is the upper fuselage — much taller and bulged outward to give a 65,000 ft³ cargo hold (about 3× the 747-400F freighter's volume). MTOW is the same 803,000 lb.

How is the Dreamlifter different from the Airbus Beluga?

Both are outsize-cargo airliner-sub-assembly ferries built from existing airliner platforms. The Dreamlifter uses a 747-400 base with a swing-tail loading system; the Airbus Beluga uses an A300 (or A330 for the BelugaXL) base with a hinged-up nose. The Dreamlifter is roughly 25% larger in MTOW.

Are any Dreamlifters retired?

No — all four airframes remain in active service as of 2026. Boeing has indicated the Dreamlifter fleet will continue ferrying 787 sub-assemblies for as long as the 787 line continues production, projected through at least 2035.
