In 1957 the French Ministry of defense called into life a new test centre to test and evaluate new aircraft and weapons systems for the French Air force, CEAM 00.330. (Centre d'Experimentations Aériennes Militaires 00.330).
The New unit's first assignments where to test the first supersonic French aircraft, the Dassault Super Mystére B2, and the first French Air-to-Air missile, the Nord 5103.
When in 1959 the Dassault Mirage III entered service the unit was known as the "Mirage Squadron". and this due to the fact that the roll of the CEAM 00.330 was expended to become a training centre for pilots and maintenance personnel.
In 1965 the Unit was awarded the Fighter squadron status and the current designation EC 05.330 was introduced.
During it's existence the squadron tested every new aircraft, fixed wing as well a rotary wing, that was to be added to the French inventory.
In 2016 the unit was designated ECE 01/30.
