The United States Space Force (USSF) is issuing a Commercial Solutions Opening (CSO) for its Operational Test and Training Infrastructure (OTTI) to acquire innovative commercial products and technologies aimed at addressing capability gaps in space testing, training environments, and advanced technologies. The CSO invites submissions from interested Offerors in a phased approach, starting with a PowerPoint briefing and white paper in Phase I, followed by an optional pitch session in Phase II, and a full proposal in Phase III for selected Offerors. This initiative is crucial for enhancing efficiency in test and training environments, with evaluations based on technical merit, applicability to agency needs, and budget considerations. Interested parties can contact Crystal Price at crystal.price.6@spaceforce.mil or Cassie DeBree at cassie.debree@spaceforce.mil for further information, and the CSO remains open indefinitely for submissions, promoting continuous innovation aligned with USSF objectives.
