Airbus Beluga: the whale-shaped outsize transporter

The Airbus Beluga, formally the A300-600ST Super Transporter, is an outsize-cargo freighter that Airbus built on the A300-600 wide-body airliner by adding a bubble-shaped cargo section. It has carried everything from wings to fuselage sections between production sites around Europe and the final assembly lines in Toulouse and Hamburg. It is known as the Beluga after the white whale it resembles, a nickname that was so popular that Airbus formally adopted it¹. The first aircraft was retired from operational service on 29 January 2026², and the others are expected to be withdrawn by 2027.

Design and development

From 1972 Airbus moved its large components in four modified Aero Spacelines Super Guppies, 1940s-era Boeing Stratocruisers that had been converted with turbine engines and custom fuselages. Over time their operating expenses grew, and rising Airbus production needed more capacity than the old fleet could provide. In August 1991 Aérospatiale and DASA formed a 50/50 joint venture, SATIC², based in Toulouse, to develop a new-build replacement for the Super Guppy fleet.

The design team chose the A300-600 as the platform; engineers cut off the top section of the fuselage¹ and added a massive bubble-shaped cargo section. The wings, engines, landing gear and lower fuselage remain identical to those of the conventional A300. To give access to the cargo area from the front without disconnecting the electrical, hydraulic and flight-control connections, the A300 cockpit was relocated below the cargo-floor level². The large one-piece main cargo door swings forwards and upwards³, with an access height of 16.78 m.

Construction of the first aircraft began in September 1992. After rollout in June 1994, the maiden flight took place on 13 September, and European certification followed the next year. The first Beluga was delivered in January 1996, marking its official entry into service. By mid-1998 all four initially ordered aircraft had been delivered¹, with a fifth added a few years later; that fifth Beluga entered service in 2000³.

Specifications

The Beluga is 56.15 m long, has a 44.84 m wingspan and stands 17.24 m high. Its maximum take-off weight is 155 t, and its GE CF6-80C2A8 engines give a cruise speed of Mach 0.7. The cargo hold is 7.08 m high and 7.04 m wide³, with a usable length of 37.70 m.

Range falls as the load grows: the Beluga can carry up to 47 t over 900 nautical miles, while lighter loads go further, for example 40 t to 1,500 nautical miles³ and 26 t to over 2,500 nautical miles. It was designed to carry large, bulky items¹, not necessarily excessively heavy ones. Its main-deck cargo volume is greater than that of the C-5 Galaxy or An-124², but its cargo-weight capacity of 47 tonnes compares with 122.5 tonnes for the C-5 Galaxy and 150 tonnes for the An-124.

The cockpit is pressurised but the cargo deck is not, although the deck is fitted with a heating module to keep cargo within an appropriate temperature range. The aircraft is operated by a crew of three: two pilots and a loadmaster². Because the main cargo deck sits 5.5 m above the ground³, the Beluga needs airports with suitable ground-handling facilities.

Operators and service

The fleet is owned by Airbus Transport International (ATI)², a wholly owned Airbus subsidiary set up to operate the type, through which it is made available for hire by third parties for charter flights. Airbus created ATI in 1996 to offer transport services in the market outside Airbus. For Airbus, the Beluga regularly carried A340 fuselage sections, A340 wings or two A320 wingsets³.

Its loads have also included space station elements, helicopters, works of art and humanitarian aid³. In 1997 a Beluga transported a chemical tank for a merchant ship, setting a world record for the biggest payload carried by air. In 1999 Eugène Delacroix’s painting Liberty Leading the People flew from Paris to Tokyo¹ on board a Beluga.

The larger BelugaXL entered service in January 2020¹. On 25 January 2022 Airbus announced Airbus Beluga Transport, an airline offering outsize cargo transportation, set up as an alternative use for the Beluga fleet after it was withdrawn from Airbus’s internal logistics network following the introduction of the BelugaXL. In January 2025 Airbus decided to close Beluga Transport² after just 14 months with its own air operator certificate.

The first aircraft to retire was Beluga ST 5, F-GSTF, flown on 29 January to the Airbus wing plant at Broughton in the United Kingdom, where Airbus states it will eventually be repurposed as a STEM facility. The remaining four were scheduled to be relocated¹ to Airbus plants or museums around the world, with the phaseout expected to be completed by 2027.
