Defence technology company Raytheon Systems Limited (RSL), the UK-based subsidiary of Raytheon Company, has opened a systems integration centre at Uxbridge in west London.
The new facility will also serve as the new, expanded site of the company's London office after RSL's expansion into the new areas of national security and defence training.
Michael Charlton, chief executive of Think London, said, "Expanding in London will ensure Raytheon can tap into a local pool of more than 500,000 experienced IT professionals."
Charlton said London, which makes up one-fifth of the UK technology market, also had the largest cluster of IT software and services companies in Europe.
RSL integrates mission-critical systems for the defence, national security and commercial sectors. It manufactures high-technology electronic systems in England, Scotland, Wales and Northern Ireland.
