There are established reports and manufacturer’s claims that would indicate two (or perhaps more) submarines are capable of speeds exceeding 30 knots (56 km/h) . In 1965, USS Albacore reported a speed of 33 knots (61 km/h), but this was not an official record.
How far can submarine travel?
A nuclear submarine can dive to a depth of about 300m . This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2,200 meters, or about 1.3 miles. The average depth of the world’s oceans is 3,790 meters, or 12,400 feet, or 2 1 ⁄ 3 miles.

How do submarines get fresh air?
Oxygen is typically supplied to the submarine from pressurized tanks . A computerized system monitors oxygen in the air and releases fresh oxygen as its needed by the crew. Next, exhaled carbon dioxide must be removed or it becomes a toxin.
