[[File:Watchkeeper-drone-Crown Copyright.jpg Watchkeeper 450 drone made by Thales. Crown Copyright 2010. Thales is a French-headquartered multinational, ranked as the world's 10th biggest weapons producer in 2016.  It is part-owned by the French government.
It builds radars, sonars and electronic surveillance satellites, tactical communication systems and combat management systems, drones, helicopter avionics, armoured vehicles, mortar systems and missiles.
Notably, Thales made the brand of surface-to-air missiles (Starstreak) controversially deployed around the London Olympic Games site in 2012. 
It also makes the infamous Watchkeeper drones, which were recently revealed to have cost the British taxpayer £1 billion pounds over the past 12 years. These aircraft are maintained by a UK-based joint venture called UAS Tactical Systems Ltd (U-TacS) with Israel's Elbit Systems, (which designed the original Hermes 450 drone that the Watchkeeper was based on).
