This is a 1:15 scale model of the Ariane 4. It was the fourth rocket built by the European Space Agency (ESA), a consortium of 11 Western European nations established in 1973 to design and produce launch vehicles and spacecraft. ESA developed six versions of the three-stage, liquid-fuel Ariane 4 that differed only in their use of liquid-fuel or solid-fuel strap-on rockets to increase boost at liftoff.
Arianespace, a component of ESA, first launched the Ariane 4 in 1988 from its complex in French Guiana, South America. Since then the reliable Ariane 4 has been successfully used over 100 times to launch a variety of government and commercial satellites. Arianespace built this model and donated it to NASM in 1987.
This object is on display in James S. McDonnell Space Hangar at the Steven F. Udvar-Hazy Center in Chantilly, VA.
