The Tactical Undersea Network Architectures (TUNA) program seeks to develop and demonstrate novel optical-fiber-based technology options and designs to temporarily restore tactical data network connectivity in a contested environment. TUNA is currently in an initial phase that emphasizes concept and technology development in three technical areas: system design, small fiber optic cable systems, and buoy nodes.
The Transformative Apps program will develop a diverse array of militarily-relevant software applications ("apps") using an innovative new development and acquisition process. A military apps marketplace will be created to enable rapid innovation to meet user needs based on a direct collaboration between a vibrant and highly competitive development community and involved communities of end-users. The program will address all the challenges-technical, business and operational to make the new capabilities available for use in the field. The objectives are to transition the resulting systems to end-users in the Services and to foster a new model for rapidly and effectively acquiring, introducing, maintaining and enhancing software.
The majority of work to develop and mature military wireless networks to date has focused on efficiency and stability in benign conditions. Insufficient attention has been paid to identifying and mitigating vulnerabilities arising from the new features being added to make these networks more efficient. Unfortunately, because of the focus on efficiency, the protocols that have been developed implicitly trust all information shared about the state of the nodes and the larger network. Consequently, when the information that is shared among these nodes is bad, the network quickly becomes unusable.
