“…Previous railguns [3] [4] [5] have been successfully operated in the 350 to 450 MPa regime. For this study, operation at 480 MPa is assumed based on improved structural designs which use high strength copper alloy rails, stiff sidewall insulators, and a combination of metal laminates and composite materials in the structure.…”

“…During that development effort, substantial improvements in the relevant technologies have been achieved. Launchers have evolved from very heavy, low bore pressure devices [1][2] to lightweight composite reinforced structures capable of operating at bore pressures near that used in conventional powder guns [3][4] [5]. Projectiles have evolved from small plastic cubes accelerated by plasma armatures [6] [7] to fully capable launch packages with integral solid armature and sabot structures supporting relevant payload projectiles [8][9] [10].…”

Abstract-Designs for future naval vessels are strongly considering electric drive systems. Already employed in commercial cruise ships, electric drive offers the advantages of increased ship design flexibility, improved efficiency, reduced maintenance and allows ship prime power to be easily diverted to other electrical loads as needed. The ability to use ship prime power generation, which ranges between 40 and 150 MW depending on vessel class, for other electric loads provides the opportunity to electrify many existing functions as well as add new performance enhancing systems. The recent and ongoing emergence of electric gun and guided projectile technologies now allows very long range naval fire support functions to be evaluated for viability. In this paper, conceptual system designs for surface fire support of forces in littoral campaigns are considered. Key advantages of an EM fire support weapon over conventional technologies include reduced logistics burden and cost per round, greater lethality, shorter time of flight, improved survivability, and the ability to stow more rounds. Notional mission requirements, projectile, power supply issues, and ship integration issues are discussed. Also, other shipboard uses for the pulse power system required for these notional electric gun systems are also reviewed.
