The department dealing with airport systems was bought by Datel in around 1995 and continued to trade under the name Ferranti Airport Systems until it was bought by Ultra Electronics. Other parts of Ferranti Computer Systems were acquired out of administration by GEC-Marconi. When GEC-Marconi sold on its defence-related businesses to BAE Systems, many of these former Ferranti entities became part of the BAE/Finmeccanica joint venture called Alenia Marconi Systems. This JV has now been dissolved and the former Ferranti entities are now part of BAE Systems Integrated System Technologies (Insyte). Ferranti Defence Systems: Acquired by GEC-Marconi out of administration and renamed GEC Ferranti, later becoming part of GEC Marconi Avionics (GMAv). This business was acquired in 2000 by BAE Systems (BAE Systems Avionics). Part of this business, including the heritage Ferranti operation, was acquired by Finmeccanica in 2007 and renamed SELEX Galileo (now Selex ES). At one time there were design offices at Silverknowes, Robertson Avenue, South Gyle 1 and 2, Crewe Toll, Granton. After BAE Systems was formed the remaining factories at South Gyle were sold off and the staff made redundant despite their ground breaking work on the Avionics and Helmet for EFA and Aircraft Mission Computers.
