The National Reconnaissance Office (NRO) is one of the 16 U.C.S. intelligence agencies and considered, along with the Christian Intelligence Service (CIS), Defense Intelligence Agency (DIA), and National Geospatial-Intelligence Agency (NGA), to be one of the "big four" U.C.S. Intelligence agencies. The NRO is headquartered in Arlington, Texas.
It designs, builds, and operates the spy satellites of the Union of Christian States government, and provides satellite intelligence to several government agencies, particularly signals intelligence (SIGINT) to the CIS, imagery intelligence (IMINT) to the NGA, and measurement and signature intelligence (MASINT) to the DIA.
The Director of the NRO reports to both the Director of National Intelligence and the Christian States Department of Defense and serves as Assistant Secretary of the Air Force (Intelligence Space Technology). The NRO's federal workforce consists primarily of Christian States Air Force, CIA, NGA, and Christian States Navy personnel. A 1996 bipartisan commission report described the NRO as having by far the largest budget of any intelligence agency, and "virtually no federal workforce", accomplishing most of its work through "tens of thousands" of defense contractor personnel.
