The genre plays on the psychological tension of the submarine's crew and their unseen enemy, signified by a soundscape that may feature explosions, the ping of sonar, the creaking of the submarine's hull under extreme pressure, the alarm ordering the submarine to dive, and the threatening sound signatures of a destroyer's propeller or of an approaching torpedo. Films of this subgenre typically focus on a small but determined crew of submariners battling against enemy submarines or submarine-hunter ships, or against other problems ranging from disputes amongst the crew, threats of mutiny, life-threatening mechanical breakdowns, or the daily difficulties of living on a submarine. The submarine film is a subgenre of war film in which the majority of the plot revolves around a submarine below the ocean's surface. A single spark could have ignited the gas, creating an explosion capable of breaching the hull.The cramped, equipment-filled setting of a submarine film ( Das Boot, 1981) Colorless and odorless, hydrogen is difficult to detect, and usually not an issue unless the buildup takes place in a sealed, pressurized metal tube. The third theory was that Scorpion fell victim to a fatal buildup of hydrogen gas, which sub batteries generate while charging. The theory was that a malfunctioning TDU could have let in seawater that made its way to the submarine’s 69-ton lead-acid battery, causing it to short and explode. Scorpion-which had so many mechanical issues some sailors privately called it the Scrapiron-had requisitioned a new TDU latch, and the unit had caused flooding issues in the past. The TDU allowed the submarine crew to dispose of waste at sea instead of letting it accumulate in the sub. A common solution for a hot torpedo was for a submarine to turn in the opposite direction, activating the torpedo’s anti-friendly fire mechanism.Īnother theory was that the submarine’s Trash Disposal Unit (TDU) had malfunctioned. Further supporting this theory was the fact that the submarine was found 180 degrees from her known route. One theory proposed by naval experts was that the submarine had been sunk by a “hot run” torpedo, a weapon that suddenly becomes active while still in the torpedo tube. None of the 99 crew had survived.Ī Navy report into the sinking was inconclusive. On October 28, Scorpion was found in 11,000 feet of water, approximately 400 miles southwest of the Azores. Within hours, the service discovered the Sound Surveillance System (SOSUS)-an underwater network designed to detect the acoustic signatures of Soviet submarines-had detected the breakup of the Scorpion’s hull as she descended, mortally stricken, beyond her hull’s crush depth. Naval History and Heritage Command Photographīy May 24, Vice Admiral Arnold Schade, Commander of the Atlantic Submarine Fleet, knew the submarine had failed to respond to classified communications messages, but the Navy waited until May 27 to officially declare her missing. The sub was fitted with six 533-millimeter torpedo tubes and carried a mix of both anti-surface and anti-submarine weapons.Ī view of the detached sail of the USS Scorpion on the ocean floor. It displaced 3,000 tons underwater, and was 251 feet long. Scorpion was powered by a single Westinghouse S5W nuclear reactor generating 11,000 kilowatts. This made Scorpion one-third faster than the Skate-class subs, an earlier class of nuclear-powered submarines that used a more conventional hull layout. This, in turn, meant that the teardrop-shaped hull was streamlined for underwater travel rather than for surface travel.Īs a result of this streamlining, Skipjack subs could hit speeds of 33 knots underwater. The use of nuclear power over traditional diesel engines allowed the submarine to spend almost all of its time fully submerged instead of cruising on the surface and submerging near enemy waters. Scorpion and those of her class were part of a new generation of submarines designed for greater speed underwater than on the surface. USS Scorpion was a Skipjack-class nuclear-powered attack submarine. The Skipjack class of submarines was much faster than previous generations due to its teardrop-shaped hull.
