Most of the companies included in this study lie within the group of top 100 global defence companies, as measured by defence revenue in 2010. In addition, in order to have a truly global range of companies, we added companies that were of an arms-exporting nationality that were not within the top 100, but which nonetheless had either actual or estimated revenue of at least USD100 million. This resulted in a final population of 129 companies from 31 countries.
Of these, 34 provided additional company-internal information and engaged in detail with TI-UK. The companies were: BAE Systems, Bechtel Corporation, Boeing, Chemring Group, CSC, Cubic Corporation, Daewoo Shipbuilding & Marine Engineering, Day & Zimmerman, Diehl Stiftung, DynCorp International, FLIR Systems, Fluor Corporation, Fujitsu, General Electric Aviation, Harris Corporation, Hewlett–Packard Company, Honeywell International, Indra, Jacobs Engineering, KBR Inc., Kongsberg Gruppen ASA, Lockheed Martin, Meggitt plc., Mitsubishi Heavy Industries, MTU Aero Engines GmbH, NEC Corporation, QinetiQ Group, Raytheon Company, Rockwell Collins, Saab AB, SAIC, Serco Group, ThyssenKrupp AG and Tognum. Four further companies wished to provide internal information but were too late to be able to be included. These were Accenture (Ireland), Aselsan (Turkey), Rafael Advanced Defense Systems (Israel) and Rheinmetall (Germany).
