O’Connor will prepare all amphibious units for operations within 3rd Fleet and for deployments worldwide.
“I am honored to have the privilege to command ESG-3,” said O’Connor, who attended St. Mark Grade School and Cathedral High.
“Adm. Daniel Fillion has superbly led this strike group for the past 18 months. He and his team have prepared each ARG-MEU to execute combat operations overseas when and where our nation has called upon them. I am humbled to relieve him and assume command of the largest strike group in the U.S. Navy.”
ESG-3 comprises three amphibious squadrons, eight naval support elements and 13 amphibious warships composed of more than 13,500 active-duty and reserve sailors and Marines.
