The report describes the results of a program to develop an explosive gun capable of launching large saboted models to reentry velocities. A secondary objective was to accelerate small projectiles to the highest possible velocity. Saboted lithium-magnesium models up to 4.5-inch diameter were launched successfully to 4.8 kmsec. Attempts to accelerate 6-inch-diameter and 7.3-inch- diameter models were not completely successful. A new velocity-mass record was achieved by accelerating a 2-gram cylindrical projectile to 12.2 kmsec.
