The decision to establish an aircraft manufacturing company was taken in 1917, but the wars that followed delayed its foundation until 1925. It was based in Phaliron near Piraeus (the same area where the AEKKEA-RAAB aircraft maker was later headquartered) and technology and initial management were provided by British Blackburn Aircraft Limited, a company selected as a partner by the Greek military. The first type produced by the factory was the T3 Velos, designed by the British company.
