Technical details
The Ariane 2 & 3 have the same design as the Ariane 1 but with increased thrust for first and second stage engines, a taller third stage, a larger internal payload fairing volume.
Ariane 3 added two solid rocket motor strap-ons.
Its payload capacity was 2175-2580 kg.
They were three-stage rocket:
The first launch of the Ariane 3 was on August 4, 1984; mostly two years before the Ariane 2. There was 11 flights; only the fifth one was a failure.
The small number of flights of the Ariane 2 & 3 is due to the arrival of the much more versatile and powerfull Ariane 4.\n
