Lockheed's acronym for the weapon is ATHENA, for Advanced Test High ENergy Asset. While it's named after the Greek goddess of wisdom, Ares would be a more appropriate name, as it's an explicit weapon of war. (Weirdly, Ares is instead the name of a cancelled NASA vehicle system). From a mile away, ATHENA burned through the engine of a truck in under a minute. The truck was mounted on a platform with the engine running, to simulate real conditions.
