Acoustic signature is used to describe a combination of acoustic emissions of sound emitters, such as those of ships and submarines.
The Soviet Union/Russian Navy Project 705 (Лира/Lira, "Lyre") was a class of hunter/killer nuclear-powered submarines.
Anechoic tiles are rubber or synthetic polymer tiles containing thousands of tiny voids, applied to the outer hulls of military ships and submarines, as well as anechoic chambers.
A bathyscaphe is a free-diving self-propelled deep-sea submersible, consisting of a crew cabin similar to a bathysphere, but suspended below a float rather than from a surface cable, as in the classic bathysphere design.
A bulkhead is an upright wall within the hull of a ship or within the fuselage of an aeroplane.
The Catalans (Catalan, French and Occitan: catalans; catalanes, Italian: catalani) are a Pyrenean/Latin European ethnic group formed by the people from, or with origins in, Catalonia (Spain), in the northeast of the Iberian Peninsula.

The Christmas season, also called the festive season, or the holiday season (mainly in the U.S. and Canada; often simply called the holidays),, is an annually recurring period recognized in many Western and Western-influenced countries that is generally considered to run from late November to early January.
Christmas Eve is the evening or entire day before Christmas Day, the festival commemorating the birth of Jesus.
Christmas traditions vary from country to country.
A cigar is a rolled bundle of dried and fermented tobacco leaves made to be smoked.
Compartmentalization in structures, such as land-based buildings, traffic tunnels, ships, aerospace vehicles, or submarines, is the fundamental basis and aim of passive fire protection.
In long, slender structural elements — such as columns or truss bars — an increase of compressive force F leads to structural failure due to buckling at lower stress than the compressive strength.
The Dolfijn-class submarines of the Royal Netherlands Navy are a class of four submarines; ''Dolfijn'', ''Zeehond'', ''Potvis'' and ''Tonijn''.
A double hull is a ship hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard, typically by a few feet, which forms a redundant barrier to seawater in case the outer hull is damaged and leaks.
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid.
In physics and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids - liquids and gases.
The hull is the watertight body of a ship or boat.
Ictíneo I was a pioneering submarine constructed in Barcelona, Spain in 1858–1859 by engineer Narcís Monturiol.
Narcís Monturiol i Estarriol (28 September 1819 – 6 September 1885) was a Spanish artist and engineer.
New Year is the time or day at which a new calendar year begins and the calendar's year count increments by one.
New Year's Day, also called simply New Year's or New Year, is observed on January 1, the first day of the year on the modern Gregorian calendar as well as the Julian calendar.
In the Gregorian calendar, New Year's Eve (also known as Old Year's Day or Saint Sylvester's Day in many countries), the last day of the year, is on 31 December which is the seventh day of Christmastide.
The Royal Netherlands Navy (Koninklijke Marine, “Royal Navy”) is the navy of the Netherlands.
Losharik (Лошарик) is the nickname of a Russian submarine.
Saddle tanks are a type of ballast tank configuration fitted to mid-era submarines, those of World War II.
Seakeeping ability or seaworthiness is a measure of how well-suited a watercraft is to conditions when underway.
Semi-submersible may refer to a self-propelled vessel, such as.
Sonar (originally an acronym for SOund Navigation And Ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels.
K-278 Komsomolets was the only Project 685 Plavnik (Плавник, meaning "fin", also known by its NATO reporting name of "Mike"-class) nuclear-powered attack submarine of the Soviet Navy.
A submarine (or simply sub) is a watercraft capable of independent operation underwater.
Depth ratings are primary design parameters and measures of a submarine's ability to operate underwater.
A submersible is a small vehicle designed to operate underwater.
A teardrop hull is a submarine hull design which emphasizes hydrodynamic flow above all other factors.
Titanium is a chemical element with symbol Ti and atomic number 22.
The German Type 212 class, also Italian Todaro class, is a highly advanced design of non-nuclear submarine developed by Howaldtswerke-Deutsche Werft AG (HDW) for the German and Italian navies.
