The United States Space Force (USSF) is seeking information on Portable Wearable Fitness Devices (PWFD) to enhance the health and wellness of its personnel, known as Guardians. The objective of this Request for Information (RFI) is to gather industry insights on innovative fitness technologies that support Continuous Fitness Assessments (CFA) while adhering to Department of Defense (DoD) security requirements. This initiative is part of the USSF's Holistic Health Approach (HHA), which emphasizes continuous monitoring of fitness metrics to improve physical health and readiness. Interested parties are encouraged to submit white papers detailing their PWFD solutions, including data management and security capabilities, to the primary contact, Crystal Price, at crystal.price.6@spaceforce.mil, or the secondary contact, Cassie DeBree, at cassie.debree@spaceforce.mil. Responses are voluntary and will inform potential future solicitations without obligating the government to a contract.
