(July 16, 1 p.m. PDT update) The following statement is from Rear Adm. Philip Sobeck, commander of Expeditionary Strike Group 3.

"After four days of firefighting, all known fires have been extinguished aboard USS Bonhomme Richard (LHD 6).

"Our fire teams are investigating every space to verify the absence of fire. Until every space is checked and there are no active fires we will not be able to commence any official investigations.

"We did not know the origin of the fire. We do not know the extent of the damage. It is too early to make any predictions or promises of what the future of the ship will be. We cannot make any conclusions, until the investigation is complete.

"What we do know is, that brave Sailors from commands all across San Diego worked tirelessly alongside federal firefighters to get this fire extinguished and I want to thank them for their efforts. This was a Navy team effort. We had support from the air and sea. Three helicopter squadrons conducted more than 1,500 water bucket drops, fighting the fire and cooling the super structure and flight deck enabling fire crews to get onboard to fight the fire.

"Tugs also provided firefighting support from the waterline, cooling the ship’s hull. We had 63 personnel, 40 U.S. Navy Sailors and 23 civilians, treated for minor injuries including heat exhaustion and smoke inhalation. We have no personnel hospitalized. The Navy continues to work together with regulators, county and state in protecting our environment and preparing to address the community’s concerns as we move forward to the next phase.

"I’d like to thank our partners from state and county, the U.S. Coast Guard, and all agencies for continued support."

(July 14, 11 a.m. PDT update) Rear Adm. Philip Sobeck, commander of Expeditionary Strike Group 3, made the following statement to open today's press conference in San Diego.

"I’d like to start by thanking the people of San Diego, National City, Coronado, and all the other communities in San Diego County for their continued support. For more than 48 hours brave Sailors from commands all across San Diego have been working tirelessly alongside Federal Fire San Diego to get this fire under control and I want to thank them for their efforts.

"I want to provide you with some updates on the progress we have made: First, we have investigated the four main engineering spaces and found no major damage. There is no threat to the fuel tanks, which is well-below any active fires or heat sources. The ship is stable and the structure is safe. We still have an active fire, which we are combatting from both within and outside the ship from multiple access points. HSC 3 helicopters have conducted more than 1,000 helicopter water bucket drops, which is cooling the super structure and flight deck enabling fire crews to get onboard internally to fight the fire. Tugs are also provide firefighting support from the waterline. I’m proud of the toughness of the Sailors and federal firefighters for making this significant progress possible.

"At this time there are 61 personnel, 38 U.S. Navy Sailors and 23 civilians, have been treated for minor injuries including heat exhaustion and smoke inhalation. Currently, there are no personnel hospitalized.

"Going forward, the Navy will do a thorough investigation of the incident to include assessing the cause of the fire and damage to the ship, but right now our focus remains on putting out the fire and keeping people safe.

"I’d like to also thank our partners from state and county as well as the Coast Guard for monitoring the potential impacts to the environment. As we continue to fight the fire, we remain cognizant of environmental concerns regarding the water and air quality. We recommend residents follow county advisories for safety out of an abundance of caution.

"Thank you again for your being here and we are now ready to take your questions."
