SHIELD
Blue and gold are traditional colors of the U.S. Navy. Gold denotes excellence and achievement. The ship takes its name from the Shoshone Indian guide, Sacagawea, who accompanied the Lewis and Clark expedition to the Northwest of the United States and was instrumental in saving the records of the journey during a boating accident. She proved to be an invaluable asset to the expedition through her ability to communicate with the tribes encountered on the journey towards the Pacific. She is shown carrying her infant, Jean-Baptiste, who accompanied the travelers along with her French trapper husband, Charbonneau. The bordure, composed of stylized Indian decoration, emphasizes Sacagaweas culture and the Indian heritage of the regions explored by the expedition.
