Submarine escape training, and a classic sub (photos)
Road Trip 2010: During a trip to the New London Submarine Base, CNET reporter Daniel Terdiman saw young Naval crew learning how to escape in an emergency. He also saw the classic Nautilus.
OK!
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. Similarly, special forces or Navy SEALS may be on board, and may need quick egress for a mission. They two would use the so-called lockout trunk on a sub to leave the vessel.
The training involves several steps, but the most important one is the successful completion of a 37-foot quick ascent made by a student in the current-generation escape unit, who is first placed into a compression chamber that simulates the proper depth, and then climbs up from the now-flooded chamber into the bottom of a huge water tank.

Here, in an image taken through a porthole onto the bottom of the tank, we see a student being given the OK sign by one of the instructors before being released.

Bushnell's Turtle
Here is a representation of Bushnell's Turtle, the world's first functional military submarine, which, according to the museum, was "designed by American revolutionary David Bushnell in 1776. [It] was the first submersible ever used in military conflict. On 6 September 1776, an American soldier propelled the 'Turtle' through New York harbor and attempted--unsuccessfully--to affix an explosive charge on the underside of a British man-of-war."
