The requirements of future gun systems have put increasing demands on the materials of construction. Our knowledge of the gun tube service environment and materials now allows us to use a materials systems design approach to design new gun systems. The gun tube environment and current gun tube materials, properties, dimensions, and fabrication methods will be reviewed, as well as the erosion test methods that have been used to characterize the in-bore environment. Fatigue, erosion and muzzle wear are the three predominant reasons for gun tube retirement, and each of these phenomena will be examined. The materials systems design approach will be used to examine a number of possible materials systems designs for advanced gun systems, and we will highlight the strengths and weaknesses of these designs.
