The One Box One Wire (OB1) Joint Combined Technology Demonstration (JCTD) is a United States Central Command (USCENTCOM) initiative that has been approved by congress for a FY 2009 rolling start. The primary goal of the JCTD Program is to demonstrate, operationally assess, and transition capability solutions and innovative concepts to address the joint, coalition and interagency operational gaps and shortfalls in meeting the needs of the warfighter. Since inception in 1995, the Advanced Concept Technology Demonstration (ACTD) Program, and now the Joint Capability Technology Demonstration (JCTD) Program, has deployed critically needed warfighting solutions to every major Combatant Command theater. The OB1 JCTD is an initiative designed to transform the existing Department of Defense (DoD) air-gapped networks (NIPR, SIPR, etc.) to an environment that allows the user to access all networks from a single PC terminal while still preserving the separation and security of data flows. This thesis will be a business case analysis of the cost of implementing and sustaining the OB1 JCTD as compared to the current DoD multi-network infrastructure. This thesis will address the question of whether converting the existing military network infrastructure into OB1 is financially feasible. This thesis will concentrate specifically on OB JCTD initiative.
