The U. S. Joint Forces Command (JFCOM) has the requirement to conduct joint experimentation for the Department of Defense (DoD). The JFCOM staff agency responsible to lead joint experiments is the J9. Joint experimentation is used to develop transformational warfighting concepts, technology, and processes through a series of wargaming and simulation activities, typically culminating with a large human-in-the-loop event. Thus far these events have been independent, each with its own setup, integration, execution, and teardown. To accelerate experimentation, include the Services and Allies, and reduce per event costs, J9 is transforming the way it executes experiments by creating the Distributed Continuous Experimentation Environment (DCEE). Initially, the DCEE will simply reduce overhead by creating a standing simulation infrastructure, including the Joint Experimental Federation (JEF) built for Millennium Challenge 2002 (MC02) and Service facilities. The DCEE will be a continuously evolving capability incorporating the latest simulation developments from the Services and other sources. DCEE expansion will be accomplished by linking additional simulations into the JEF, embedding new models in the existing federates, and linking with other federations. Preliminary DCEE development efforts have included: integrating scaleable computing power via the inclusion of DoD High Performance Computing assets; the development of a worldwide terrain database with high resolution inserts, including urban environments; developing a real time data collection and analysis capability; and developing simulation monitoring and control functions. A network of J9 and Service sites is being established to provide USJFCOM with a highly flexible, evolving, and distributed experimentation capability based on interlinked federations of simulations.
