The USS Sailfish, originally known as the USS Squalus (SS-192), underwent a remarkable transformation from a sunken submarine to an operational vessel. In May 1939, the Squalus sank during a test dive off the coast of Portsmouth, New Hampshire, leading to a rescue mission that saved 33 crew members. The event garnered national attention and was a pivotal moment for the U.S. Navy, highlighting the importance of submarine safety procedures. After the successful recovery of the vessel, extensive repairs and modifications were carried out to ensure its functionality and safety.

On May 15, 1940, the USS Sailfish was officially recommissioned at the Portsmouth Navy Yard. This event marked not only the resurrection of a vessel that had faced dire circumstances but also the ingenuity and perseverance of naval engineers and crews tasked with restoring it. The reconceptualization of the ship underscores the U.S. Navy's commitment to technology and human resourcefulness during a challenging pre-war period.

The USS Sailfish went on to serve with distinction, participating in various military operations during World War II. The experience gained from the Squalus incident led to significant changes in submarine training and safety protocols, ultimately improving the effectiveness and safety of submarine operations within the fleet.
