About USNS Sumner

USNS Sumner (T-AGS-61) is a Pathfinder-class oceanographic survey ship that became operational in 1997. It is the fourth United States Navy ship named Sumner, in this case for Thomas Hubbard Sumner, an American sea captain who discovered the principles of celestial navigation by circle of equal altitude. These ships are crewed by a small crew of civilian mariners, supporting an even smaller contingent of United States Navy personnel. According to Carol Rosenberg, writing in the Miami Herald, the vessel was scheduled to be placed out of service in 2014. Rosenberg reported speculation that Summer would be transferred to the United States Coast Guard. The Coast Guard would use the ship to counter smugglers in the Caribbean Sea, where she would be stationed as a permanent helicopter station. Coast Guard sharpshooters could be quickly dispatched to intercept and apprehend smugglers.
