The chairman of the Joint Chiefs of Staff Committee is the deputy chairman of the Development Control Committee (DCC), the body responsible for weapons development and oversight which includes the nation's military and scientific, but not its political, leadership. Through DCC, the senior civilian scientists maintains a tight control of scientific and ethical research; the DCC exercises technical, financial and administrative control over all strategic organisations, including national laboratories and scientific research and development organisations associated with the development and modernisation of nuclear weapons and their delivery systems. Functioning through the SPD, the DCC oversees the systematic progress of weapon systems to fulfil the force goals set by the committee.
