One part of the exercise, designated NIFC-CA AS-02A, resulted in the then-longest surface-to-air engagement in naval history;[27] the exact range of the intercept was not publicly released.[28] On 14 August 2014, an SM-6 was test fired against a subsonic, low-altitude cruise missile target and successfully intercepted it over land. A key element of the test was to assess its ability to discern a slow-moving target among ground clutter.[3] On 24 October 2014, Raytheon announced that two SM-6 missiles intercepted anti-ship and cruise missile targets during "engage on remote" scenarios. A low-altitude, short-range supersonic GQM-163A and a low-altitude, medium-range subsonic BQM-74E were shot down by SM-6s fired from a guided-missile cruiser using targeting information provided by a guided-missile destroyer.
