[6] HAI was founded by the Greek State in 1975, by decision of Constantine Karamanlis' government, to undertake all aircraft-related construction activity, so that the historic KEA factory would concentrate on maintenance work.

In 1990, HAI developed in collaboration with DASA of Germany, Alenia of Italy and Per Udsen of Denmark the "Advanced Amphibious Aircraft" (AAA) which, however, was not produced.

Other developments that were not completed mostly for financial reasons at the time, include a trainer for the Hellenic Air Force of own design and many joint projects.

[7] In March 2007, HAI joined EADS in the "Eurofighter" project, undertaking the construction of a composite fuselage part (Vary Cowl) for the Typhoon.

In April 2007, HAI signed an agreement with the United States Air Force for the structural and electronic upgrade (CCIP) of all US F-16 fighters that harbor in Europe, in its facilities in Greece.

Since 2005 HAI has been actively involved in the design and construction of part of the new Boeing Dreamliner 787 and specifically the CDS (Cargo Door Surround) of this new airliner.

HAI is also involved in the design and construction, using composite material, of the prototype part of the internal force structure of the wing of the new AIRBUS A380 (TANGO project).

In 2010, the Hellenic Aerospace Industry was considered one of several Greek state owned enterprises requiring restructuring, because it had a primary revenue deficit.

and existing manufacturing equipment capabilities cover the following production range: Product Manufacturing capabilities include, HAI's Research and Development projects are listed below: Lockheed Martin has provided valuable assistance both in terms of workload and new technology through the F-16 co-production program and has also invested on HAI’s aerostructures facility expansion to accommodate growth of this program.
