On 16 July, five days after the explosion, the Navy announced that all fires had been extinguished. The minor injury total had risen to 63 total (40 sailors and 23 civilians). Admiral Michael Gilday, Chief of Naval Operations, said the event was "a very, very serious incident" and that the Navy would address any systemic problems. He said the firefighting efforts had involved sailors from many ships and units in San Diego, including the helicopter squadron HSC-3, which dropped water on the ship.
