The UK/US technical co-operation programmes cover a wide range of missile defence activities. These include current and future missile threat assessment, threat launch detection, threat tracking, command and control aspects, sensors, weapon systems and the consequences of interception. The joint co-operation programmes have allowed both the UK and US to improve our joint understanding of missile defence issues, and have allowed UK-developed technology with potential missile defence applications to be demonstrated to the US.
