What project 677 buys
The Secure Unclassified Network (SUNet) provides critical infrastructure for fast-moving AI development missions, Interagency Task Force groups, and experimental DoW missions that cannot be met by other existing capabilities. SUNet is the Department’s only one off Department of Defense Information Network (DODIN), Government-owned (GOTS) network and compute platform that is authorized to support data and missions up to the CUI level. SUNet adheres to DoW Risk Management Framework standards and is accessible anywhere in the world with internet. The platform acts as a sandbox and provides segmented, customizable areas of compute and storage for DoW and mission partners to rapidly onboard, collaborate, develop, and validate cutting edge commercial software and tools. Mission owners across the Department rely on SUNet’s flexible and accessible infrastructure to achieve their AI/ML missions and maintain operational advantage.

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. Each describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.
FY 2027 funding will continue to fund the legacy platform, as well as fund the development of the next generation SUNet system. The deliberate overlap of the legacy system and next generation system will ensure continuity of operations for AI/ML mission owners across the Department, as well as using recently procured hardware.
