What does this number measure?
A European launch vehicle that carried satellites and scientific missions. Ariane 5 notably launched the James Webb Space Telescope. Its height depends on the version and fairing; the reference represents a common configuration.
Compare the stated dimensions
The comparison uses the number in each fact sheet: altitude, height, diameter, length or distance, depending on the reference. Two values in metres do not necessarily describe the same property.
Source and limitations
Catalogue order of magnitude; a source is provided, but this measurement has not been individually audited.
Complete Ariane 5, vertical height.
First launch: 1996. Proposed historical date; an existing documentary source is linked but was not consulted for this date in this session. Do not interpret this reference as the manufacturing date of the illustrated specimen. Ariane 5's first launch in 1996 failed; this reference does not mean its first success or entry into commercial service.
