The US Navy's railgun project's badge (see this YouTube video at timecode 00:14) has the motto "Velocitas Eradico" — I have no formal instruction in Latin, but my familiarity with Romance languages and etymology leads me to believe the translation would be "With speed, eliminate/destroy [the target]" — that is: the railgun fires projectiles so fast the need for an explosive warhead is eliminated. To double-check this I put it into Google Translate and it gave me "get rid of speed" — which seems like the complete opposite of what the railgun project is about :S
Is either translation correct? Or are both wrong?
