The Raytheon Broughton facility is located at Hawarden Airport, Broughton, in North Wales, close to the city of Chester.

This facility was developed to undertake systems integration work, in particular for the ASTOR (Airborne Stand-Off Radar) programme. Broughton is carrying out the modification and integration of the Sentinel R Mk 1 aircraft and the integration of the Ground Stations. In addition to utilising the site's own indigenous capability and skills in specialised airframe modification work, Broughton benefits from technology transfer from the United States. .
