The Europa rocket was an early expendable launch system of the European Launcher Development Organisation (ELDO), which was the precursor to the European Space Agency (ESA). It was developed with the aim to delivering space access technology, and more specifically to facilitate the deployment of European-wide telecommunication and meteorological satellites into orbit.

The program ultimately traces its history to the British Blue Streak missile, which was cancelled in 1960. Blue Streak was then used as the basis of the Black Prince expendable launch system and several other concepts. Looking for partners to share development costs, ELDO was formed and began development of the Europa using the Blue Streak first stage along with the French-built Coralie second stage and German Astris upper stage.^[1]

The programme proceeded to perform multiple test launches but these frequently resulted in partial failures. In addition, Britain decided to pull out of the ELDO organisation, and thus Europa, to focus on the rival all-British Black Arrow launcher instead. Confidence in the programme had diminished due to the poor reliability figures, and this led to its termination.

Although the UK left the program, the other ELDO partners were still interested in a launcher. They re-formed as the European Space Agency (ESA) in 1974 and proceeded to develop the Ariane family of launchers, which would prove to be a commercial success with hundreds of launches performed.
