## Summary

This activity requests $19.8M in FY2027, 11% of project UN5, down 17% on FY2026. The R-2A exhibit describes it across FY2025–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** Efforts support advanced experimentation activities with joint warfighters to identify chemical and biological (CB) defense capability gaps across the services. FY 2027 efforts integrates software capabilities developed under the CB WEARABLES program line with additional tactical, readiness, and performance monitoring functions. Integrate these capabilities into ground-based U.S. Air Force and Army data movement and management systems used across multiple domains. Develop and integrate decision support tools to enable operational and medical commanders at the wing/brigade and below level to monitor and predict warfighter readiness, performance, and health before, during, and after operations in CB environments.

**FY2026 to FY2027 change.** Funding decrease from FY 2026 to FY 2027 due to cost savings from integrating previously developed Army-Focused capabilities into data systems owned by other services.

## Before the request year

**FY2026 plans — current year.** Efforts support advanced experimentation activities with joint warfighters to identify CB defense capability gaps across the services. FY 2026 efforts integrates software capabilities developed under the CB WEARABLES program line with additional tactical, readiness, and performance monitoring functions (the CB WEARABLES line integrates software capabilities transitioned from the PM2S program starting in FY 2026). Integrates these capabilities onto additional U.S. Air Force-focused data movement & management systems used across multiple domains and echelons. Develops and integrates decision support tools to enable operational and medical commanders of all levels to monitor and predict warfighter readiness, performance, and health before, during, and after operations in CB environments.

**FY2025 accomplishments.** Integrated software capabilities developed under the Physiological Monitoring Sensor Suite (PM2S) program with additional tactical, readiness, and performance monitoring functions. Integrated these capabilities onto U.S. Air Force data movement networks operating across multiple domains and echelons. Developed and integrated decision support tools to enable operational and medical commanders of all levels to monitor and predict warfighter readiness, performance, and health before, during, and after operations in chemical and biological (CB) environments.
