A team lead by the sons of her commanding officer, Mannert Lincoln "Jim" Abele, found USS Grunion (SS-216) approximately 10 miles northeast of Kiska in the Aleutian Islands. On August 16, 2006, they discovered a probable submarine wreck, and produced sonar images of it. The vessel shown here lies at a depth of over 2000 feet.

The following year the Abele brothers sent down an unmanned remotely operated vehicle (ROV), and photographed the wrecksite. After detailed analysis, the U.S. Navy confirmed the identity of the vessel as USS Grunion.

Secrets of the Sub

How Does A Sub Stay So Quiet

How do submarines stay so quiet?

Submarines are the ultimate “stealth weapon. Remaining underwater to attack or use its sensors, quietness is critical. Through design, modern nuclear submarines have equipment mounted on special mounts to isolate the noise from the outside and reduce the noise signature of the sub in the ocean. Rotating equipment is checked from the design through operation so it is always quiet and it is immediately repaired if it is not operating quietly. The sub checks itself with its own acoustic sensors and establishes the most quiet lineup of equipment for normal or critical operations. Overall, the reason the submarine is so quiet is because every member of the crew knows how important it is to remain quiet and undetected ensuring the submarine can perform all of its mission.
