Major structural sections of the A380 are built in France, Germany, Spain, and the United Kingdom. Due to the sections' large size, traditional transportation methods proved unfeasible, so they are brought to the "Jean-Luc Lagardère Plant" assembly hall in Toulouse, France, by specialised road and water transportation, though some parts are moved by the A300-600ST "Beluga" transport aircraft. A380 components are provided by suppliers from around the world; the four largest contributors, by value, are Rolls-Royce, Safran, United Technologies and General Electric.
