Europe's Spaceport - Ariane 4 Launch Site  
Introduction

The Spaceport's ELA-2 launch complex supported the Ariane 4 vehicle family's fast-paced launch schedule from its service entry in 1986 through the final Ariane 4 mission in 2003.

The complex consisted of two areas: the launcher preparation zone and the launch zone. These two areas were separated, allowing one launcher to undergo final checkout and payload integration in the launch zone while a second was being assembled in the launcher preparation zone.

ELA-2 was designed for approximately 10-11 launches per year with an interval of one month between successive missions. Arianespace maintained a high operational mission rate throughout the Ariane 4 program to meet the commercial demand.
