SEAL for his first deployment. Women Until December 2015, female sailors were barred from becoming Navy SEALs by naval regulation; however, this prohibition no longer exists. As early as August 2015, it was reported that the "Navy is planning to open its elite SEAL teams to women who can pass the grueling training regimen." In that same month, Admiral Jon Greenert, the Chief of Naval Operations at the time, said that "he and the head of Naval Special Warfare Command, Rear Admiral Brian Losey, believe that if women can pass the legendary six-month Basic Underwater Demolition/SEAL (BUD/S) training, they should be allowed to serve." On 3 December 2015, it was announced that there are now "no exceptions" to all military roles in the U.S., and women can become U.S. Navy SEALs. The Washington Examiner reported on 10 August 2017: "A woman aiming to become the first female Navy SEAL officer quit about a week into the initial training". In 2019 the Navy announced that an unnamed female officer was the first to successfully complete the SEAL Officer Assessment and Selection program (SOAS). She was one of a group of five female candidates to enter the program. She opted not to start BUD/S afterwards, instead choosing another assignment in the Navy. In July 2021, the Naval Special Warfare (NSW) training program graduated its first woman operator, who would go on to become a Special Warfare Combatant-craft Crewman (SWCC). This would mark the first time a woman has graduated from the NSW assessment and selection pipeline.
