Happy 250th birthday to the United States Navy! Born in Philadelphia on October 13th, 1775, the U.S. Navy began as a small fleet of twenty-seven ships. From its humble origins, the U.S. Navy has grown into the world’s most powerful maritime force, guided by the words “Not Self - But Country.” Today we pay tribute to 250 years of the United States Navy and honor the service of all Sailors, past and present. #MemDayPBS #MemorialDay #NavyBirthday | National Memorial Day Concert (PBS)
