EADS 3 Sigma is the name since 2002 (when its majority was acquired by the European EADS Group) of the Greek 3 Sigma aerospace company. It was founded in 1987 with headquarters in Athens and production facilities in Chania, Crete. It has designed, produced and exported a variety of Unmanned Aerial Vehicles - including the Iris, Alkyon, Perseas (also available with single- and twin-jet engines), and 3 Sigma Nearchos types - as well as various electronics; its areas of research and development, in collaboration with Greek Universities, have included engine and remote control technologies.
EADS 3 Sigma announced in November 2012 that the company was in liquidation as it was no longer financially viable to continue the operations of the company.
