The Naval Submarine Base New London is the United States Navy's primary East Coast submarine base, also known as the "Home of the Submarine Force". It is located in Groton, Connecticut.

At the Naval Submarine Base New London thousands of students go through Submarine School, which encompasses the varied curriculum required of a Naval submariner.

One element of the school is escape training, where the students are taught, over two days, the steps required for a safe and orderly escape from a submarine in turmoil.

How do you escape from a sinking submarine?
Most U.S. Navy submarines have two escape routescalled "escape trunks"that can be used to escape if ever needed. They work like an "air lock" that you may have seen in a movie. The men climb into the escape trunk wearing a special life preserver that has a hood on it to provide a bubble of air to breathe. When the lower hatch is shut, the trunk is filled with water and pressurized to sea pressure. The trunk's outside hatch opens, and the men float to the surface.

How are people rescued from a sunken submarine?
There are systems built into the submarine to assist the crew to escape safely, if required. The Navy has also developed two rescue submarines called Deep Submersible Rescue Vehicles (DSRV). You may have seen them in the movies, Hunt for Red October, or Gray Lady Down. They drive up to the damaged submarine, mate to the escape hatch and take the crew to safety. New technologies are planned for incorporation into the next generation rescue system called the "Submarine Rescue Diving and Recompression System."
