Overview
Why this aircraft matters
Four passenger 747-400 airframes were converted with a bulbous cargo fuselage and swing-tail loading system. The fourth and final aircraft entered service in 2010.
Size and design
Unlike conventional freighters, the rear fuselage swings sideways so very large but relatively light aerospace structures can be loaded into the main deck.
At 71.68 metres long and 64.44 metres across, the 747-400 Dreamlifter occupies a very different physical envelope from an everyday single-aisle airliner. Dimensions alone do not tell the entire story: payload, cabin volume and intended role determine how that space is used.
Operators and current status
Atlas Air for Boeing.
In Boeing logistics service. Operator lists can change; they are reviewed against first-party material and are not a live fleet-tracking service.
Notable records
- One of the largest cargo compartments by volume
- Four converted aircraft support Boeing production logistics
Source notes
Boeing confirms the 747-400 conversion, four-aircraft fleet and role. Dimensions refer to the LCF configuration; payload capability varies by mission and published definition.
