### Project 345 — Defense Operations Security Initiative

DOSI establishes and leads the Department's next-generation OPSEC capability development and affiliated investment strategy. Investments support DoW's current and emerging OPSEC capability gaps, including countering advances in non-U.S. ISR capabilities and denying the understanding of U.S. capability, capacity, readiness, and critical technology and information from adversaries. These investments spur Department innovation and preserve U.S. technology superiority. DOSI analyses and engineering activities lead the community's ability to sustain and maximize technology advantages as they are transitioned to Service and Agency programs for sustainment, maintenance, and capacity programming. Results of tests and evaluations enable the community to identify OPSEC measure and countermeasure effectiveness in current and emerging operational environments.
