190604-N-GZ947-0107 PEARL HARBOR (June 4, 2019) Quartermaster Seaman Apprentice Jacob Wenzel, from Saginaw, Mich., salutes the national ensign after hoisting the union jack aboard the guided-missile destroyer USS Chung-Hoon (DDG 93). The union jack, comprising the national ensign’s blue field and white stars, was first adopted on June 14, 1777. At this time, the jack’s blue field only displayed the 13 stars representing the union of the original 13 American colonies. The number of stars on the jack was periodically updated as the United States expanded. (U.S. Navy photo by Mass Communication Specialist 2nd Class Kenneth Rodriguez Santiago/Released)
