USNS Sacagawea (T-AKE-2), a Lewis and Clark-class dry cargo ship, was the third ship operated by the United States Navy to be named for Sacagawea, the Shoshone woman who acted as guide and interpreter for the Lewis and Clark Expedition, and one of the few United States Navy ships named for women.
The contract to build her was awarded to National Steel and Shipbuilding Company (NASSCO) of San Diego, California, on 18 October 2001. Construction began in September 2004 for a scheduled delivery in early 2007.
She was launched in June 2006. Two of Sacagawea's descendants, Lucy Diaz and Rachel Ariwite, were the ship's sponsors. She is home ported at Naval Station Norfolk, Virginia, and made her first deployment at the end of 2007.
This vessel is the only USNS Sacagawea. However, other U.S. Navy vessels have been named USS Sacagawea.
