A discussion of the Joint Strike Fighter's PHM system and its relationship to the far-reaching autonomic logistics (AL) support concept is presented in this paper. By design, PHM is one of the key enabler for this new and revolutionary AL support concept. Overall PHM architecture is described with emphasis on its capabilities and its aims to enhance aircraft safety; improve sortie generation rate; decrease logistics footprint; and significant reduce operation and support costs. The key elements of the AL concept are presented. Program background, user "needs", and potential benefits are explored; and related to show how the PHM and AutoLog visions evolved to their current concept and status.
