The dual-use defense technology EFA GROUP announces a strategic investment through the acquisition of a 90% majority stake in Superior Air, marking the EFA GROUP’s dynamic entry into the fields of Maintenance, Repair and Overhaul (MRO), aviation training, and specialized aviation services in helicopters and airplanes.
Superior Air provides comprehensive General Aviation services in Greece and internationally.

The strategic investment by EFA GROUP in Superior Air significantly strengthens the Group’s operational footprint, particularly in technical support and the upgrade of military aircraft, while also enhancing its capabilities in the civil aviation sector.
Through this investment, EFA GROUP will be able to undertake and execute complex aircraft support and upgrade projects, while also providing training services in the Defense and Security sectors, by combining the Group’s existing solutions and products with Superior Air’s service offering.
Superior Air’s operational presence extends across five strategic bases: Megara (Megara Airport), Koropi (Helipad), Mykonos (Helipad), Santorini (Helipad), and Sparta (Sparta Airport), ensuring broad geographic coverage and a high level of operational readiness nationwide.
