The Capability Development Framework (CDF) was originally produced by the Domestic Nuclear Detection Office (DNDO) in 2011 to provide state, local, territorial, and tribal stakeholders with a decision support tool for identifying their specific RN target and transit risks and the appropriate level of capability to counter these risks. The CDF draws on a variety of different factors to assess the overall risk within five categories: Interior Population Centers, Special Events, Interior Pathways, Land Borders and Maritime.
