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 stage was equipped with 4 solid propellant engine.
• The second had one N2O4/UDMH bipropellant engine.

This design will be kept until the Ariane 4.

Launch history

The first launch of the Ariane 2 was on May 30, 1986 and was a failure. The next ones were all successful. There was only a few flights of the Ariane 2, 6 in total, the last on April 2, 1989.

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 powerful Ariane 4.
