OMSI is home to the U.S. Navy's last non-nuclear, fast-attack submarine, the USS Blueback (SS-581). The Blueback was the first battle-ready class of submarines to use the teardrop hull. It was in official operation throughout the Pacific Ocean for 31 years.

The USS Blueback served in the entertainment industry, too! It was used as a location for a Discovery Channel documentary and various commercials, and it appeared in the hit movie The Hunt for Red October and an episode of Hawaii Five-O.
