The suspected shooter was training at the US Naval Air Station in Pensacola for two years, according to Defense Department spokesperson Christopher Garver.
Two law enforcement sources tell CNN the suspect's name is Mohammed Alshamrani.
Alshamrani's training began in August 2017 and was scheduled to conclude in August next year, Garver said. His training program included English language training, basic aviation, and initial pilot training. The training was funded by the Kingdom of Saudi Arabia.
Alshamrani was vetted upon entry to the US and checked again after the shooting with nothing of concern found, a law enforcement source told CNN.
Secretary of Defense Mark Esper vowed to assist service members and staff affected by the shootings this week at two separate naval bases.
"To all our sailors, soldiers, airmen, and marines, and civilian personnel, we stand ready to assist and make resources available to deal with the grief in the aftermath of these tragedies as well as life's challenges in general," he said.
"I offer my condolences to the families of the victims of both the Pearl Harbor and the Pensacola Naval Air Station shootings. The Department of Defense continues to monitor the situation in Pensacola and gather all the facts of each attack. I've spoken with Governor DeSantis, the Secretary of the Navy, and Deputy Secretary Norquist and am considering several steps to ensure the security of our military installations and the safety of our service members and their families. I'm grateful for the heroism of the first responders and law enforcement who helped confront both situations and kept further loss of life from occurring."
