An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, one has yet to successfully land on one. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the role of flagship of a fleet. One of its great advantages is that, by sailing in international waters, it does not interfere with any territorial sovereignty and thus obviates the need for overflight authorizations from third-party countries, reduces the times and transit distances of aircraft and therefore significantly increase the time of availability on the combat zone.
The Kirov class, Soviet designation Project 1144 Orlan, is a class of nuclear-powered guided missile cruisers of the Soviet Navy and Russian Navy, the largest and heaviest surface combatant warships in operation in the world. Among modern warships, they are second in size only to large aircraft carriers, and of similar size to a World War I-era battleship. The Soviet classification of the ship-type is "heavy nuclear-powered guided missile cruiser". The ships are often referred to as battlecruisers by Western defence commentators due to their size and general appearance.
A ship prefix is a combination of letters, usually, abbreviations, used in front of the name of a civilian or naval ship that has historically served numerous purposes, such as identifying the vessel's mode of propulsion, purpose, or ownership/nationality. In the modern environment, prefixes are used inconsistently in civilian service, whereas in government service, the vessels prefix is seldom missing due to government regulations dictating a certain prefix be present. Today the common practice is to use a single prefix for all warships of a nation's navy, and other prefixes for auxiliaries and ships of allied services, such as coast guards. For example, the modern navy of Japan adopts the prefix "JS" – Japanese Ship. However, not all navies used prefixes; this includes the significant navies of China, France, Russia, and Spain, which, like France, uses the NATO designation SPS if needed.
Technical research ships were used by the United States Navy during the 1960s to gather intelligence by monitoring, recording and analyzing wireless electronic communications of nations in various parts of the world. At the time these ships were active, the mission of the ships was covert and discussion of the true mission was prohibited. The mission of the ships was publicly given as conducting research into atmospheric and communications phenomena. However, the true mission was more or less an open secret and the ships were commonly referred to as "spy ships".
HMS Caroline is a decommissioned C-class light cruiser of the Royal Navy that saw combat service in the First World War and served as an administrative centre in the Second World War. Caroline was launched and commissioned in 1914. At the time of her decommissioning in 2011 she was the second-oldest ship in Royal Navy service, after HMS Victory. She served as a static headquarters and training ship for the Royal Naval Reserve, based in Alexandra Dock, Belfast, Northern Ireland, for the later stages of her career. She was converted into a museum ship. From October 2016 she underwent inspection and repairs to her hull at Harland and Wolff and opened to the public on 1 July 2017 at Alexandra Dock in the Titanic Quarter in Belfast.
United States Naval Ship (USNS) is the prefix designation given to non-commissioned ships that are property of the United States Navy (USN).
A tracking ship, also called a missile range instrumentation ship or range ship, is a ship equipped with antennas and electronics to support the launching and tracking of missiles and rockets. Since many missile ranges launch over ocean areas for safety reasons, range ships are used to extend the range of shore-based tracking facilities.
The Cannon class was a class of destroyer escorts built by the United States primarily for antisubmarine warfare and convoy escort service during World War II. The lead ship, USS Cannon, was commissioned on 26 September 1943 at Wilmington, Delaware. Of the 116 ships ordered, 44 were cancelled and six were commissioned directly into the Free French Forces. Destroyer escorts were regular companions escorting vulnerable cargo ships.
Battleship Memorial Park is a military history park and museum on the western shore of Mobile Bay in Mobile, Alabama. It has a collection of notable aircraft and museum ships including the South Dakota-class battleship USS Alabama and Gato-class submarine USS Drum. USS Alabama and USS Drum are both National Historic Landmarks; the park as a whole was listed on the Alabama Register of Landmarks and Heritage prior to that time, on October 28, 1977.
Shardul-class landing ships are large amphibious warfare vessels built at Garden Reach Shipbuilders and Engineers for the Indian Navy. They are an evolution of the Magar-class amphibious landing ships.
The master, or sailing master, is a historical rank for a naval officer trained in and responsible for the navigation of a sailing vessel. The rank can be equated to a professional seaman and specialist in navigation, rather than as a military commander.
The P2 transport was a United States Maritime Commission design for a passenger ship which could be readily converted into a troop transport. Three variants of the design were built, the P2-SE2-R1 (Admirals), P2-S2-R2 (Generals), and P2-SE2-R3 (Presidents).
