They are Airbus’s delivery ships of the sky.
The Airbus A300-600ST Beluga is built using many of the components from the standard A300-600 wide-body airliner. The ST in the designator stands for the original name: Super Transporter. It is a super transporter, but the name Beluga stuck and hasn’t let go.
There are a total of five operational Belugas flying aircraft components between factories spread around Europe. Unmistakable for their size and appearance, the A300-600STs have been incrementally updated, upgraded, and improved during their 21 years of service. Belugas have performed charter flights to carry outsized cargo such as a huge chemical tank for a merchant vessel, two complete NH90 helicopters and a single Eurocopter Tiger attack helicopter from France to Melbourne in Australia for the Avalon Airshow, and large / voluminous space vehicle components and satellites for multiple national space programs including the National Aeronautics and Space Administration (NASA) and the former Soviet Union. Belugas have also flown relief supplies to areas devastated by tsunamis and hurricanes.
