Which organization is responsible for the regulation of unmanned aircraft in the United States?

The Federal Aviation Administration (FAA) is the organization responsible for regulating unmanned aircraft in the United States. This includes the establishment of safety standards, operational guidelines, and certification processes for both commercial and recreational drone use. The FAA's authority encompasses airspace management, ensuring that unmanned aircraft operate safely alongside manned aircraft, and developing regulations that address the unique challenges posed by drones.

Other government agencies like NASA may be involved in research and development related to unmanned aircraft technologies, and the Department of Transportation oversees transportation policies, but it is the FAA that specifically manages the aviation regulations. The Department of Defense focuses on military operations and regulations related to unmanned systems used for defense purposes, further distinguishing its role from that of the FAA.
