Originally a public domain film from the US Navy, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Submarine warfare is one of the four divisions of underwater warfare, the others being anti-submarine warfare, mine warfare and mine countermeasures.
Submarine warfare consists primarily of diesel and nuclear submarines using torpedoes, missiles or nuclear weapons, as well as advanced sensing equipment, to attack other submarines, ships, or land targets. Submarines may also be used for reconnaissance and landing of special forces as well as deterrence. In some navies they may be used for task force screening. The effectiveness of submarine warfare partly depends on the anti-submarine warfare carried out in response...
Post-World War II
Since the Second World War, several wars, such as the Korean War, Indo-Pakistani War of 1971 and the Falklands War, have involved limited use of submarines. Later submarine-launched land-attack missiles were employed against Iraq and Afghanistan. With these exceptions, submarine warfare ceased after 1945. Hence strategic thinking about the role of submarines has developed independently of actual experience.
The advent of the nuclear-powered submarine in the 1950s brought about a major change in strategic thinking about submarine warfare. These boats could operate faster, deeper and had much longer endurance. They could be larger and so became missile launching platforms. In response to this the attack submarine became more important, particularly in regard to its postulated role as a hunter-killer. The US also used nuclear submarines as radar pickets for a while. There have also been major advances in sensors and weapons.
During the Cold War, the United States and the Soviet Union played what was described as a 'cat-and-mouse' game of detecting and even trailing enemy submarines.
As the likelihood of unrestricted submarine warfare has diminished, thinking about conventional submarines has focused on their use against surface warship. The mere existence of a submarine may curtail surface warships' freedom to operate. To counter the threat of these submarines, hunter submarines were developed in turn. The role of the submarine has extended with the use of submarine-launched autonomous unmanned vehicles. The development of new air independent propulsion methods has meant that the diesel-electric submarine's need to surface, making it vulnerable, has been reduced. Nuclear submarines, although far larger, could generate their own air and water for an extended duration, meaning their need to surface was limited in any case.
In today's more fractured geopolitical system, many nations are building and/or upgrading their submarines. The Japan Maritime Self-Defense Force has launched new models of submarines every few years; South Korea has upgraded the already capable Type 209(Chang Bogo class) design from Germany and sold copies to Indonesia. Russia has improved the old Soviet Kilo model into what strategic analysts are calling equivalent to the 1980s-era Los Angeles class, and so on.
At the end of his naval warfare book The Price of Admiralty, military historian John Keegan postulates that eventually, almost all roles of surface warships will be taken over by submarines, as they will be the only naval units capable of evading the increasing intelligence capabilities (space satellites, airplanes etc.) that a fight between evenly matched modern states could bring to bear on them.
However, thinking about importance of the submarine has shifted to an even more strategic role, with the advent of the nuclear ballistic missile submarine carrying Submarine-launched ballistic missiles with nuclear weapons to provide second strike capability...
