The mission of this naval reserve unit is to "provide line management staffing of the National Reconnaissance Office; coordinate naval space research, development, and acquisition between NRO and other non-naval space programs; and provide naval space and warfare experience to develop superior and affordable space systems in support of national missions and joint, combined, and naval operations."

This SPAWAR Space Field Activity (SSFA) headquarters unit provides staff-level augmentation to the Commander, SSFA for management, development, acquisition, operation, and logistics support of National Classified space systems and their ground segments. The 0866 HQ unit provides technical reservist support to the National Space Infrastructures. 0866 also acts as the single point of contact for administrative matters between the Space and Network Warfare Program (SNWP) and the SSFA reserve units, and for executive management of the entire reserve team supporting the National Reconnaissance Office (NRO).
