Department of Defense (DoD) and industry acquisition integrated product teams delivering virtual training systems to international customers must consider exportability and program protection issues common to, and often beyond, those of the corresponding live platforms. DoD Instruction 5000.02 requires DoD program managers to consider exportability and program protection throughout the acquisition lifecycle, ensuring the ability for international partners to procure defense articles while mitigating risks of potential loss of critical program information or technology to potential adversaries. Virtual training systems may contain classified military information, controlled unclassified information, or proprietary information required to replicate or simulate the live platform and its behavior in a synthetic environment. DoD's ability to provide Government-furnished information for International Armament Cooperative Programs and Foreign Military Sales programs is constrained by numerous DoD policies and issuances as well as federal law. Incorrect assumptions by industry, DoD, and international customers regarding DoD's ability to provide classified military information, controlled unclassified information, or proprietary information may lead to cost and schedule overruns and inability to provide capabilities previously advertised to the customer. This paper defines perspectives on exportability and program protection in the DoD acquisition lifecycle and discusses the relevance of these perspectives to acquisition of virtual training systems. After defining methods of international acquisition of defense articles, the paper aggregates numerous DoD issuances regarding exportability and program protection into perspectives that DoD acquisition personnel may reference in drafting documents and conducting other program activities relating to virtual training system acquisition. The paper concludes with recommendations for DoD, industry, and international customers to consider with the mindset of delivering a valid training system within customer cost and schedule constraints.
