SELEX Sistemi Integrati S.p.A. was an aerospace, defence and security-related electronics manufacturing company headquartered in Rome, Italy, and a wholly owned subsidiary of Finmeccanica.

[1] In 1951, Finmeccanica and the United States–based company Raytheon formed Microlambda, a joint venture based in Fusaro near Naples, operating in the field of applied electronics and producing radar systems under licence for land and naval applications.

In 1960, an international agreement led to the creation of Selenia – Associated Electronics Industries, a joint venture focused on civil and military surveillance systems whose shareholders were Finmeccanica (40%), Raytheon (40%) and Edison (20%).

Solutions[buzzword] for Homeland Defence are related to the design and realisation of net-centric architectures able to operate into an inter-force and interoperable context to reach the superiority of information.

With the fixed (FADR) and deployable (DADR) version of RAT31DL, SELEX Sistemi Integrati was the main European supplier of 3D long-range radar into the NATO area.
