So far, General Atomics has proposed for the Golden Dome 3 variants of the electromagnetic cannon, varying in the size of the "gun" and missiles, as well as the power needed to "fire" (3 by 10 to 32 megajoules). The smallest gun, marked Blitzer, is to have a power of 3 megajoules and a power supply strategy contained in a 6.5” Tricon container. This set is most likely proposed for terrestrial mobile systems.
