In the 1970s, the division's mission responsibilities expanded to include occupational and environmental health oversight for the Air Force, when occupational health laboratories at McClellan Air Force Base, California and Kelly Air Force Base, Texas were combined with a radiological laboratory at Wright-Patterson Air Force Base, into the Air Force Occupational and Environmental Health Laboratory at Brooks. In the following decade, the division's mission expanded beyond aeromedical research, and included development and fielding of biotechnology systems, doing not only research and testing but following through with the production of systems. Its hospital and clinic responsibilities, on the other hand were transferred to another organization.
