Report warns lunar mass drivers and electromagnetic catapults could be repurposed as first-strike weapons A new analysis argues that emerging Moon “mass driver” and electromagnetic catapult concepts—associated with launch and offloading—raise security risks because they could be adapted into first-strike weapon systems. The report frames lunar surface launchers as a potential accelerant for military disruption in the Moon–Earth environment.
