The Human Effectiveness Directorate (RH) is the heart of Airman-centered science and technology for the Air Force. RH is focused on enduring challenges to enable, sustain, and enhance multi-domain capable Airman and Airman-machine operations.

RH leverages five primary Technical Competencies to deliver technology options for future USAF capabilities:

• Training
• Adaptive Warfighter Interfaces
• Bioeffects
• Bioengineering
• Warfighter Medical Optimization

The Human Effectiveness Directorate develops Airman-related technology for systems crucial to continued aerospace superiority. We work to transfer the same or similar technology to civilian applications when appropriate. We are organized into three divisions located at Wright-Patterson Air Force Base and San Antonio, Texas.

• Warfighter Interactions & Readiness Division (RHW) – Enable a more informed, agile, and lethal force by delivering revolutionary capabilities that enhance preparation and mission execution across the full range of military operations.
• Air and Space Biosciences Division (RHB) – Discover, demonstrate, and transition knowledge products and technology solutions from the full spectrum of bioscience, biotechnology and aerospace medicine, to enable, enhance, sustain, and restore the health and performance of the multi-domain Airman and Guardians.
• Bioeffects Division (RHD) – Protect against and exploit the bioeffects of battlefield environmental stressors.
