USS Hawkbill (SSN 666) was launched on April 12, 1969 at the Mare Island Naval Shipyard and was the last of the Sturgeon class (637) Fast Attack Submarine. Hawkbill was decommissioned on March 15, 2000. The sail was shipped to the Idaho Science Center in Arco, Idaho to be part of a museum, not far from the Idaho National Lab site where the first submarine nuclear power plant prototype was built and operated.
USS Hawkbill was stationed in Pearl Harbor in 1975 as a part of Submarine Squadron One, and remained there longer than any other Pearl Harbor-based Pacific Fleet Submarine.
Notable operations included USS Hawkbill completed two successful Scientific Ice Expeditions to the North Pole and a historic voyage around the world. The Arctic mission (SCICEX) was a joint venture between the Navy and the National Science Foundation (NSF), and Hawkbill made the last Arctic cruise for any pacific fleet Sturgeon class nuclear-powered submarine.
