 | | At the time this was the longest submerged cruise by a submarine and at the highest sustained speed (for at least one hour) ever recorded. |
 | | Radar and anti-submarine aircraft, which had proved crucial in defeating submarines during the War, proved ineffective against a vessel able to move out of an area in record time, change depth quickly and stay submerged for very long periods. |
 | | Nautilus now serves as a museum of submarine history, after undergoing a five-month preservation in 2002, at the Electric Boat division of General Dynamics, at a cost of approximately $4.7 million. |
