A ship class is a group of ships of a similar design. This is distinct from a ship type, which might reflect a similarity of tonnage or intended use. For example, USS Carl Vinson is a nuclear aircraft carrier (ship type) of the Nimitz class (ship class).

Sixteen vessels were ordered in September 1914 (as well as four of the Yarrow M class ), but part of their cost was met by the provision in the 1914–15 Programme for ten destroyers. Nine further vessels were ordered in early November 1914 (as well as one further Yarrow M class ). Twenty-two further vessels were ordered in late November 1914. Sixteen further vessels were ordered in February 1915 (as well as two more of

Ships of the same class may be referred to as sister ships . The name of a naval ship class is most commonly the name of
156-458: A single letter suffix. After the reunification of Germany the German Navy ( Deutsche Marine ) kept the system. Informally, classes are also traditionally named after their lead ships. The Indonesian Navy has a traditional naming system for its ships. In addition, the ship's type and missions can be identified by the first number on the ship's three-digit hull number , which is placed on

All ships were built to an identical – Admiralty – design, hence the class name. Eighteen other vessels which were officially included within
208-526: The Confederate States Navy . Generally accepted by military historians and widely used in the more recent books, webpages and papers on the subject matter (most notably the releases of Osprey Publishing ), these latter-day classifications are sometimes considered "semi-official" (although they are not). Contemporary records, such as the " Official Records of the Union and Confederate Navies in
234-650: The Thornycroft M class ). The eight last-named below of these were of the Repeat M subgroup with raking stems compared with the straight stems of the previous sub-group, and the bows were more flared to improve seakeeping qualities. Eighteen final vessels were ordered in May 1915 (as well as two of the Thornycroft M class and two of the Yarrow M class ). However, two of the eighteen were fitted with geared turbines and became
260-474: The lead ship , the first ship commissioned or built of its design. However, other systems can be used without confusion or conflict. A descriptive name may be used; for example it was decided to group destroyers made to the same design as HMS Tomahawk , all named after weapons, as the Weapon rather than Tomahawk class. In European navies, a class is named after the first ship commissioned regardless of when it
286-416: The 'M' class were built to variant designs by three specialist builders – 10 by Yarrow , 6 by Thornycroft (who also built another 6 to the standard Admiralty design), and 2 by Hawthorn Leslie ; these are covered in other articles. The Admiralty design was based on the preceding L class but modified to produce an increase in speed by approximately 6 knots (11 km/h; 6.9 mph). All ships built to

#1732782666248312-546: The Admiralty design had three identical narrow, circular funnels (this did not apply to the 18 ships built by the specialist yards). An original intention to order 20 destroyers in this year's Programme was reduced to 16 vessels. Three destroyers already under construction were purchased from Yarrow, two from Thornycroft and two from Hawthorn Leslie to these builders' individual designs, and these are listed in separate articles. Three further ships had been projected under
338-537: The Programme – and named Marksman , Menace and Monitor ; however these three ships were cancelled before being contracted to any specific builder (although J. Samuel White & Company , at Cowes were the intended builder), in favour of two Marksman -class leaders . Thus just six vessels were built to the Admiralty design under the 1913–14 Naval Programme. These differed from the wartime vessels by being 1,010 tons full load, with slightly smaller dimensions. All
364-586: The War of the Rebellion " (Series 2, Volume 1, Part 1), show that the modern nomenclature was not in use at the time. The unofficial retro-applying of ship classes can occasionally lead to confusion. For example, while American works consistently adhere to the City - and Columbia -class monikers, works of British origin refer to the same classes as Cairo class and Tennessee class respectively, in compliance with
390-582: The accepted European convention, some classes have been named after a common theme in the included ships' names, e.g., Tribal-class destroyers , and some classes were implemented as an organizational tool, making traditional methods of naming inefficient. For instance, the Amphion class is also known as the A class. Most destroyer classes were known by the initial letter used in naming the vessels, e.g., V and W-class destroyers . Classification by letter also helped to conflate similar smaller classes of ships as in
416-593: The case of the A-class destroyers of 1913 whose names spread across the alphabet. Since the end of the Second World War , Royal Navy ship classes have also been known by their type number (e.g. Type 45 destroyer .) For the United States Navy , the first ship in a class to be authorized by Congress is the designated class leader and gives the name to the class, regardless of the order in which
442-413: The course of building a class of ships, design changes might be implemented. In such a case, the ships of different design might not be considered of the same class; each variation would either be its own class, or a subclass of the original class (see County-class cruiser for an example). If ships are built of a class whose production had been discontinued, a similar distinction might be made. Ships in
468-673: The current convention to historical naval vessels sharing similarities, such as those of the American Civil War , where the Union Navy built several vessels in series, which can be termed "classes" as presently understood. Common examples include the Passaic -class monitor and the City-class ironclad , among many others, for the Union side, and Columbia class or Richmond class , for those ironclads in service with
494-519: The following vessels were ordered in five batches as part of the War Emergency Programme . Wartime builds omitted the cruising turbines originally specified and carried by the pre-war sub-group. The funnel heights were also raised compared with the pre-war vessels, and the second 4 in gun was mounted on a bandstand, as with the earlier L-class destroyers. Partridge , Norman , Maenad , Ophelia and Observer were later fitted to carry
520-788: The front bows and the back of the stern. The naming convention is: Russian (and Soviet ) ship classes are formally named by the numbered project that designed them. That project sometimes, but not always, had a metaphorical name, and almost always had a NATO reporting name . In addition, the ships of the class would have a number prefixed by a letter indicating the role of that type of vessel. For example, Project 641 had no name, though NATO referred to its members as Foxtrot-class submarines . The ship classification does not completely correspond common designation, particularly for destroyers, frigates and corvettes. Russia has its own classification system for these ships: The British Royal Navy (RN) has used several methods of naming classes. In addition to

#1732782666248572-661: The modern Royal Navy naming conventions. By the time the United States entered World War II, the current naming convention was in place, though it remains unclear as to exactly how and when the practice originated. Merchant ships are almost always classed by a classification society . These vessels are said to be in class when their hull, structures, machinery, and equipment conform to International Maritime Organization and MARPOL standards. Vessels out of class may be uninsurable and/or not permitted to sail by other agencies. A vessel's class may include endorsements for
598-494: The prototypes for the Admiralty R class destroyers (these were the Radstock and Raider , and are listed with the R class). The other sixteen were all to the Admiralty design were of the Repeat M subgroup with raking stems apart from the two ships ordered from White as Redmill and Redwing , which were completed to the earlier 'M' Class design and were renamed Medina and Medway while building.

650-459: The ships of that class are laid down, launched or commissioned. Due to numbering conventions, the lead ship often has the lowest hull number of its class. (During World War II , the award of construction contracts was not always congruent with completion, so several ships had higher hull numbers than later ships.) Before the 1920s, naval vessels were classified according to shared characteristics. However, naval historians and scholars retro-apply
676-606: Was ordered or laid down. In some cases this has resulted in different class names being used in European and U.S. references; for example, European sources record the Colorado -class battleships of the United States Navy as the " Maryland class", as USS Maryland was commissioned before USS Colorado . The West German Navy ( Bundesmarine ) used a three-digit type number for every class in service or in advanced project state. Modified versions were identified by
