A submarine is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as "boats" rather than "ships" irrespective of their size.

Charles Bowers Momsen, nicknamed "Swede", was born in Flushing, New York. He was an American pioneer in submarine rescue for the United States Navy, and he invented the underwater escape device later called the "Momsen lung", for which he received the Navy Distinguished Service Medal in 1929. In May 1939, Momsen directed the rescue of the crew of Squalus (SS-192).
Air-independent propulsion (AIP), or air-independent power, is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen. AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.

Submarine Escape Immersion Equipment (SEIE), also known as Submarine Escape and Immersion Equipment, is a whole-body suit and one-man life raft that was first produced in 1952. It was designed by British company RFD Beaufort Limited and allows submariners to escape from a sunken submarine. The suit also provides protection against hypothermia and has replaced the Steinke hood rescue device. The suit allows survivors to escape a disabled submarine at depths down to 600 feet (183 m), with an ascent speed of 2–3 meters/second, at a rate of eight or more sailors per hour.
