USS Triton Sail Park
USS Triton (SSRN 586) made history in 1960 as the first submarine to circle the earth underwater, following the path of explorer Ferdinand Magellan.
Port of Benton worked with the U.S. Navy to preserve the submarine’s sail and conning tower that are on display at the USS Triton Sail Park to honor submariners.
Triton’s sail was the largest ever aboard an American submarine, measuring 75 feet (22.9 meters) long and 20 feet (6.1 meters) tall. The massive structure stowed retractable radar masts, radio antennas and periscopes when not in use.
Triton was the last U.S. submarine with a conning tower. This small water-tight compartment inside the sail protected critical equipment and command crew during a battle.
Visit the Public Park
Groups and individuals are encouraged to visit the sail park. The park is open year-round for self-guided tours of the vessel’s exterior with displays that share the story of this first-generation nuclear-powered U.S. submarine.
See Inside the Sail
Tours inside Triton’s sail must be scheduled with the Port by completing our tour request form and a liability release form.
During the tour, guests explore the submarine’s conning tower, where the original instruments are still in place and learn about Triton’s historical impact as a deterrent during the Cold War.
Tour guides also share the community’s rich military history, including our region’s role in World War II and the Cold War.

USS Triton Sail Park Dedication
The dedication of the USS Triton Sail Park was held on November 10, 2011, in Richland, Washington, exactly 52 years after the submarine’s commissioning.
The USS Triton Sail Park overlooks the Port’s barge slip and high-dock facility on the Columbia River. The location is symbolic because the dock is where the Navy transfers nuclear reactor compartments from decommissioned vessels (including Triton) onshore for delivery to the nearby Hanford Site for permanent storage.
