It represented an advancement of the Ariane 1 rather than a replacement, but was capable of lifting even heavier payloads into Geostationary transfer orbit (GTO).
[6] The Ariane 1 soon became considered to be a capable and competitive launcher in comparison to rival platforms offered by the Soviet Union and the United States.
[7] However, even prior to the launcher entering service, there was a strong desire to quickly produce improved derivatives that would be able to handle even greater payloads than Ariane 1 could.
[8] While the initiative was first proposed in 1978, prior to the Ariane 1's first flight, approval to commence the first phase of development was not received until July 1979.
The Ariane 2 was designed to satisfy the future demand for the delivery of two tonne payloads into a Geosynchronous transfer orbit (GTO).
[9] The principal agency behind the development of the Ariane 2 was the Centre National d'Etudes Spatiales (CNES), while the lead company for its production was the French aerospace manufacturer Aérospatiale.
[7] Even prior to the maiden flight of the Ariane 2, the family had been able to secure the majority of the global launcher market.
