The Under Secretary of Defense (Acquisition, Technology and Logistics) directed the Services in 2009 to jointly
develop and demonstrate a common architecture for command and control of Department of Defense (DoD) Unmanned
Aircraft Systems (UAS) Groups 2 through 5.
The UAS Control Segment (UCS) Architecture is an architecture framework for specifying and designing the softwareintensive
capabilities of current and emerging UCS systems in the DoD inventory. The UCS Architecture is based on
Service Oriented Architecture (SOA) principles that will be adopted by each of the Services as a common basis for
acquiring, integrating, and extending the capabilities of the UAS Control Segment.
The UAS Task Force established the UCS Working Group to develop and support the UCS Architecture. The Working
Group currently has over three hundred members, and is open to qualified representatives from DoD-approved defense
contractors, academia, and the Government. The UCS Architecture is currently at Release 2.2, with Release 3.0 planned
for July 2013. This paper discusses the current and planned elements of the UCS Architecture, and related activities of
the UCS Community of Interest.
