The Home Office has awarded its £650m eBorders contract to a consortium led by Raytheon Systems.
The project will see the development and implementation of the nation's "e-Borders" project, an advanced border control and security programme.
Members of the Trusted Borders consortium have already started work on the e-Borders programme, building upon the country's current pilot programme for border control and expanding it into a scalable e-Borders capability within two years.
Ninety-five percent of the work will be carried out in the UK.
As the prime contractor for the Trusted Borders consortium, Raytheon will be responsible for systems integration, travel services and overall project management, drawing upon its extensive development and production base in the UK as well as the company's worldwide technology resources.
Supporting members of the consortium include Serco, Accenture and Capgemini.
