This paper presents a portion of an analysis to determine what performance levels EML (electromagnetic launcher) subsystems must achieve to enable EM armament in future weapons systems. In particular, this paper presents the sensitivity of EML viability to (1) the power per unit volume of a pulsed power supply, (2) the efficiency of that power supply, (3) the launch event efficiency, (4) the number of rounds stowed, and (5) the maximum projectile energy attainable. The result is a definition of the minimum performance levels useful for the tactical application considered. Development of alternatives that do not recognize these high system level requirements will not lead to tactical advantages compared to conventional systems. This analysis indicates that EML technology can provide a viable armament alternative for future armored land combat systems requiring high energy projectiles and high on-board projectile count. In order to achieve that goal pulsed power supplies must realize 8000 kW/m3 with efficiency exceeding 60%. In addition, the pulsed power must support a system including launch efficiency exceeding 70% for large caliber or 55% for medium caliber armament
