Auxiliary Fleet
An auxiliary ship is a naval ship designed to support combatant ships and other naval operations. Auxiliary ships are not primary combatant vessels, though they may have some limited combat capacity, usually for purposes of self-defense. Auxiliary ships are extremely important for navies of all sizes because if they were not present the primary fleet vessels would be unsupported. Thus, virtually every navy maintains an extensive fleet of auxiliary ships. However, the composition and size of these auxiliary fleets vary depending on the nature of each navy and its primary mission. Smaller coastal navies tend to have smaller auxiliary vessels focusing primarily on littoral and training support roles. Larger blue-water navies tend to have larger auxiliary fleets comprising longer-range fleet support vessels designed to provide support far beyond territorial waters. Roles Replenishment One of the most direct ways that auxiliary ships support the fleet is by providing under ...

Navy Supply Vessel "Berlin"
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications (brown-water navy), open-ocean applications ( bl ...

Ironclads
An ironclad is a steam-propelled warship protected by iron or steel armor plates, constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, , was launched by the French Navy in November 1859 - narrowly pre-empting the British Royal Navy. They were first used in warfare in 1862 during the American Civil War, when ironclads operated against wooden ships and, in a historic confrontation, against each other at the Battle of Hampton Roads in Virginia. Their performance demonstrated that the ironclad had replaced the unarmored ship of the line as the most powerful warship afloat. Ironclad gunboats became very successful in the American Civil War. Ironclads were designed for several uses, including as high seas battleships, long-range cruisers, and coastal defense ships. Rapid development of warship design in the late 19th century transformed the iron ...

Cargo Ship
A cargo ship or freighter is a merchant ship that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with crane (machine), cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of welded steel, and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped. Definitions The words ''cargo'' and ''freight'' have become interchangeable in casual usage. Technically, "cargo" refers to the goods carried aboard the ship for hire, while "freight" refers to the act of carrying of such cargo, but the terms have been used interchangeably for centuries. Generally, the modern ocean shipping business is divided into two classes: # Liner business: typically (but not exclusively) container vessels (where ...

Torpedo Boat Tender
The torpedo boat tender was a type of warship developed at the end of the 19th century to help bring small torpedo boats to the high seas, and launch them for attack. During the Turko-Russian war in 1877, the Russians requisitioned 19 trade vessels to convert them as torpedo boat tenders. '' Velikiy Knyaz Konstantin'' was the first historical vessel in this new ship class. She was captained by Stepan Makarov, who was major naval engineer, early practitioner of torpedo usage and the author of concept of torpedo boat tender. On 14 January 1878, Makarov performed the first successful attack by self-propelled torpedoes in history. The Turkish ship ''Intibah'' was destroyed by torpedo boats launched from ''Velikiy Knyaz Konstantin''. In 1878, the British Navy commissioned the ''Hecla'' as a torpedo boat tender, followed by HMS Vulcan (1889). The 1896 French ship ''Foudre'' was a torpedo boat tender, before it was converted to a seaplane carrier. During World War II, the type evol ...

Seaplane Tender
A seaplane tender is a boat or ship that supports the operation of seaplanes. Some of these vessels, known as seaplane carriers, could not only carry seaplanes but also provided all the facilities needed for their operation; these ships are regarded by some as the first aircraft carriers and appeared just before the First World War. Terminology In maritime parlance a tender is a vessel that is used to support the operation of other vessels. In British usage, the term tender was used for small craft, with the term depot ship being used for large seagoing vessels. Flying boats and float planes even when based at home in ports and harbour had a need for small support vessels to operate.p British tenders were small craft of launch to pinnace size. These were used to ferry crews, stores and supplies between shore and the aircraft, to maintain the buoys used to mark out "taxiways" and "runways" and to keep these clear of debris to prevent foreign object damage, and in the case of ...

Submarine Tender
A submarine tender is a type of depot ship that supplies and supports submarines. Development Submarines are small compared to most oceangoing vessels, and generally do not have the ability to carry large amounts of food, fuel, torpedoes, and other supplies, nor to carry a full array of maintenance equipment and personnel. The tender carries all these, and either meets submarines at sea to replenish them or provides these services while docked at a port near the area where the submarines are operating. In some navies, the tenders were equipped with workshops for maintenance, and as floating dormitories with relief crews. With the increased size and automation of modern submarines, plus in some navies the introduction of nuclear power, tenders are no longer as necessary for fuel as they once were. Canada Canada's first Submarine Depot Ship was . Chile The term used in the Chilean Navy is "submarine mother ship", as for example the BMS (buque madre de submarinos) ''Almirante M ...

Destroyer Tender
A destroyer tender or destroyer depot ship is a type of depot ship: an auxiliary ship designed to provide maintenance support to a flotilla of destroyers or other small warships. The use of this class has faded from its peak in the first half of the 20th century as the roles and weaponry of small combatants have evolved (in conjunction with technological advances in propulsion reliability and efficiency). Background As the industrial revolution progressed, steam-powered steel ships replaced sail-powered wooden ships; but naval artillery remained the preferred weapon. The first large warship to be sunk by a torpedo was the Chilean ironclad in 1891. As major naval powers realized the vulnerability of their expensive battleships to inexpensive torpedo boats, they started building defensive flotillas of torpedo boat destroyers or destroyers for short.Potter & Nimitz, p.335 The earliest torpedo boat destroyers were small, to maximize maneuverability, and powered by large steam engin ...

Seaplane
A seaplane is a powered fixed-wing aircraft capable of takeoff, taking off and water landing, landing (alighting) on water.Gunston, "The Cambridge Aerospace Dictionary", 2009. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called ''hydroplanes'', but currently this term applies instead to Hydroplane (boat), motor-powered watercraft that use the technique of Planing (boat), hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of the investments in airports during the war but mainly because landplanes were less constrained by weather conditions that could result in sea states being too high to operate seaplan ...

Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unattended o ...

Submarine
A submarine (or sub) 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 Autonomous underwater vehicle, 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. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Ship's Tender
A ship's tender, usually referred to as a tender, is a boat, or a larger ship, used to service or support other boats or ships. This is generally done by transporting people or supplies to and from shore or another ship. A second and distinctly different meaning for ''tender'' is small boats carried by larger vessels, to be used either as lifeboats, or as transport to shore, or both. Tenders as smaller craft For a variety of reasons, it is not always advisable to try to tie a ship up at a dock; the weather or the sea might be rough, the time might be short, or the ship too large to fit. In such cases tenders provide the link from ship to shore, and may have a very busy schedule of back-and-forth trips while the ship is in port. On cruise ships, lifeboat tenders do double duty, serving as tenders in day-to-day activities, but fully equipped to act as lifeboats in an emergency. They are generally carried on davits just above the promenade deck, and may at first glance appear to ...

Ammunition Ship
An ammunition ship is an auxiliary ship specially configured to carry ammunition, usually for naval ships and aircraft. An ammunition ship's cargo handling systems, designed with extreme safety in mind, include ammunition hoists with airlocks between decks, and mechanisms for flooding entire compartments with sea water in case of emergencies. Ammunition ships most often deliver their cargo to other ships using underway replenishment, using both connected replenishment and vertical replenishment. To a lesser extent, they transport ammunition from one shore-based weapons station to another. In the United States Navy U.S. Navy ammunition ships are frequently named for volcanos. During World War II, U.S. Navy ammunition ships were converted from merchant ships or specially built on merchant ship hulls, often of Type C2 ship, Type C2. They were armed, and were manned by naval crews. Several of them were destroyed in spectacular explosions during the war, such as , which exploded in t ...
