We have had UAVs around in the UK for a fair few years with Phoenix in service with the Royal Artillery, procured as an artillery spooting UAV. More recently it has been used for intelligence gathering in Bosnia etc. There are currently plans for the UK military to obtain UAVs but as to what type i believe no decision has been made. As to entering service in the RAF, i hear that the Army Air Corps are going to become resposible for all UAVs, including Phoenix.
