A review of developments in logistics support over the past decade is presented. The concepts of systems engineering, the “system approach,” and the need for system effectiveness in military weapons has created a revolution in the traditional concepts of engineering and logistics. One major problem has been the introduction into the traditional aerospace organizational division, of engineering and logistics of several new disciplines (e.g., reliability, maintainability, personnel subsystem, value engineering, and so forth). Owing in large part to recent Department of Defense specifications, the traditional definitions and concepts of logistics must be changed.
