What modeling or testing has been done on using electromagnetic railguns (EMRGs) for launching low Earth orbit (LEO) projectiles?

DSIAC was asked for information pertaining to the capability of current EMRG systems to support the launch of objects, mainly SmallSats in the CubeSat/nanosatellite to femtosatellite class. Their masses must range from 0.01 kg to 10 kg, from the Earth to LEO and from the Moon’s surface to a Mars transfer orbit. A DSIAC subject matter expert in propulsion systems at The Johns Hopkins University Energetics Research Group provided commentary on the capabilities and issues with using an EMRG in such a manner and reference documents.
