"Franchetti will bring 38 years of dedicated service to our nation as a commissioned officer, including in her current role of Vice Chief of Naval Operations," Biden said in a statement.

"She is the second woman ever to achieve the rank of four-star admiral in the United States Navy, and when confirmed, she will again make history as the first woman to serve as the Chief of Naval Operations and on the Joint Chiefs of Staff," he said.

Franchetti has served on a series of surface vessels, including as commander of a guided missile destroyer, a destroyer squadron and two carrier strike groups

She was deputy commander of US naval forces in Europe and as well as in Africa, and deputy chief of naval operations for warfighting development. She became vice chief of naval operations in September 2022.

Admiral Mike Gilday is due to complete his four-year term as head of the Navy next month, but it is unclear if Franchetti will be confirmed by the Senate in time.

Republican Senator Tommy Tuberville has stalled more than 200 senior military nominations to protest the Pentagon's decision to assist troops who have to travel to receive abortions or other reproductive health care that is not available where they are stationed.

Biden took aim at Tuberville in the statement, saying that delaying the approval of the nominees "is not only wrong -- it is dangerous."

"In this moment of rapidly evolving security environments and intense competition, he is risking our ability to ensure that the United States Armed Forces remain the greatest fighting force in the history of the world. And his Republican colleagues in the Senate know it," the president said.

Gilday would hand over to Franchetti in her capacity as his deputy in the event she is not confirmed when he leaves office, mirroring the current situation in the Marine Corps.

General Eric Smith -- the assistant commandant -- has been nominated to head the service, but has yet to be confirmed and has been serving in an acting capacity since July 10.

Other top officers are also due to leave office in the coming months, including Chief of Staff of the Army General James McConville and Chairman of the Joint Chiefs of Staff General Mark Milley.
