The USS Grunion (SS 216) is best known for her mysterious dissappearance. Until recently, little was known of the last whereabouts of the vessel and her 70 crew members. It was known that she had been attacked after experiencing extensive anti-submarine activity off Kiska near the Aleutian Islands but besides her last radio transmission, she was never heard from again - reported lost on August 16, 1942.
The USS Grunion was a Gato-class submarine - one of 77 such submarines produced by the United States of America during World War 2. She sailed away from New London after her shakedown voyage and participated in the rescue of some 16 American sailors in the Caribbean Sea - victims of a German U-boat attack. She would later traverse through Panama and arrive at Pearl Harbor on June 20th before being sent to the Aleutian Islands for combat patrols of enemy shipping.
Grunion operated in these seas throughout the month of July until on July 30th, a transmission was received from her about the high level of anti-submarine activity that was developing. To avoid her falling fate to enemy action, the vessel was ordered back to the relative safety of Dutch Harbor. It is at this time that the Grunion was never heard from again. Rescue searches ensued to no avail.
