Some considerations for reengineering Navy legacy systems

Abstract

Navy shipboard and aircraft systems and the super systems in which they interoperate are some of the most complex computer based systems in the world. This together with the sheer number of platforms, their long service lives, and rolling upgrades schedules make reengineering them a formidable task. In this paper some of the considerations involved are laid out, some of the possible approaches are shown to be undesirable, and current efforts and needed work are discussed.
