The Defense Information Systems Agency said Thursday the types of projects include technology developments, demonstrations, concept of operations and analysis.
The portfolio was developed as a result of a technical concept assessment in 2015 hosted by DSO and the offices of the DoD chief information officer and the assistant secretary of defense for research and engineering, DISA added.
According to the agency, participants in the technical concept assessment evaluated 237 concepts and integrated them into the investment portfolio during the follow-on portfolio development phase.
The SAR&DP portfolio currently awaits funding approval and transfer from the Spectrum Relocation Fund Resources Oversight Group and the Office of Management and Budget, DISA said.
DSO is a DISA component that works to support electromagnetic spectrum operations across DoD.
