Search for Lost Submarines

In the first sixty years after the end of World War II, no one was able to find any of the 52 American submarines lost during the War whose exact locations were not already known.  In most cases, the submarines were lost with all hands, and the exact locations of their sinkings were "lost to history."

Advances in technology and the dedication of those who seek to explore the depths has changed all that. Since 2005, divers have discovered five sunken submarines.

Further discoveries are expected.

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.
