The USS Squalus sank during a shakedown cruise on May 23, 1939. The USS Sculpin aided the rescue ship Falcon to rescue 33 men from the Squalus which was at a depth of about 240 feet. 26 men drowned in the flooded aft section of the Squalus. The rescue effort captivated the attention of the entire nation. On February 9, 1940, after being raised to the surface and refurbished, the USS Squalus SS 192 was renamed USS Sailfish SS 192.
