The following is the complete July 22, 2015 statement from the Naval Sea Systems Command on the July 18 incident.
On July 18 at approximately 9 a.m. (EDT) a Standard Missile-2 (SM-2) test missile exploded after suffering a malfunction as it was fired from the guided-missile destroyer USS The Sullivans (DDG 68) during a planned missile exercise off the coast of Virginia. There were no injuries and only minor damage to the port side of the ship resulting from missile debris. The ship returned to Naval Station Norfolk for assessment. An investigation into the malfunction has been ordered and is being conducted by the Navy’s Program Executive Office for Integrated Warfare Systems, which is part of Naval Sea Systems Command. It is too early to determine what, if any, effect this will have on the ship’s schedule.
