USS Blueback was the last non-nuclear powered submarine built by the U.S. Navy, and the last to be decommissioned after serving her country for 31 years. Blueback and her sister ships of the Barbel class utilized radical new concepts in post World War II submarine design, the most important being the teardrop hull and a single propeller. Blueback was decommissioned on 1 October 1990 and laid up in the Pacific Reserve Fleet in Bremerton, Washington. The USS Blueback was acquired by the Oregon Museum of Science and Industry, Portland, Oregon, in February 1994. This submarine appeared in the 1990 film The Hunt for Red October before being towed to its present location, a pier right outside the museum. It was opened to the public on May 15, 1994.
