The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use.
The Finnish Navy is one of the branches of the Finnish Defence Forces. The navy employs 2,300 people and about 4,300 conscripts are trained each year.

The Finnish Navy also includes coastal forces and coastal artillery.
The names of commissioned ships of the United States Navy all start with USS, for United States Ship. Non-commissioned, primarily civilian-crewed vessels of the U.S. Navy under the Military Sealift Command have names that begin with USNS, standing for United States Naval Ship. A letter-based hull classification symbol is used to designate a vessel's type. The names of ships are selected by the Secretary of the Navy. The names are those of states, cities, towns, important persons, important locations, famous battles, fish, and ideals. Usually, different types of ships have names originated from different types of sources.

The Type 062 gunboat is a class of gunboat of the People's Liberation Army Navy first developed and constructed in the 1950s. This unsophisticated class is relatively well-armed for its size and is the most widely built and exported Chinese naval vessel in terms of numbers. A total of 30 were built, initial boats being known as the Shanghai I class and later slightly improved boats being known as the Shanghai II class. The Shanghai I class was slightly smaller than its successor, the Shanghai II class, displacing 125 tons instead of 135 tons, and had a twin Chinese Type 66 57 mm gun mount forward. All other specifications are identical to the Shanghai II class, which replaced the 57 mm with twin 37 mm gun mounts. Some boats remained in active service well into the early 1990s in the PLA navy and longer in the case of the Korean People's Navy.
The Type 037 corvette is a series 400–500 ton corvette type classes in service with the People's Liberation Army Navy. Unlike western navies, the People's Liberation Army Navy does not have dedicated patrol boats in its inventory. Instead, a large variety of corvette type classes, in the form of missile boats and submarine chasers fulfill the tasks of patrolling China's territorial waters. The Egyptian Navy operates eight vessels.
United States ship naming conventions for the U.S. Navy were established by congressional action at least as early as 1862. Title 13, section 1531, of the U.S. Code, enacted in that year, reads, in part,
The vessels of the Navy shall be named by the Secretary of the Navy under direction of the President according to the following rule: Sailing-vessels of the first class shall be named after the States of the Union, those of the second class after the rivers, those of the third class after the principal cities and towns and those of the fourth class as the President may direct.
Naval trawlers are vessels built along the lines of a fishing trawler but fitted out for naval purposes; they were widely used during the First and Second World Wars. Some, known in the Royal Navy as "Admiralty trawlers", were purpose-built to naval specifications; others were adapted from civilian use. Fishing trawlers were particularly suited for many naval requirements because they were robust vessels designed to work heavy trawls in all types of weather, and had large clear working decks. A minesweeper could be created by replacing the trawl with a mine sweep. Adding depth charge racks on the deck, ASDIC sonar below, and a 3-inch (76 mm) or 4-inch (102 mm) gun in the bow equipped the trawler for anti-submarine duties.
Type 912 degaussing/deperming ship (ADG) is a type of little known auxiliary ships built in the People's Republic of China (PRC) for the People's Liberation Army Navy (PLAN), and this class has several derivatives. As of 2022, Type 912 is the most numerous degaussing/deperming ship in PLAN, and the longest serving degaussing/deperming ships in PLAN, until its successor ype 911 finally begun to appear in early 2010s.
Type 911 degaussing/deperming ship is a type of very little known auxiliary ship currently in service with the People's Liberation Army Navy (PLAN). Designed to replace earlier Type 912 degaussing/deperming ship, Type 911 has received NATO reporting name Dazar class, and as of early 2022, a total of two ships have been identified.
Ankang class ambulance craft is a class of little known naval auxiliary ship currently in service with the People's Liberation Army Navy (PLAN). The exact type still remains unknown, because the only official Chinese governmental information released on these crafts is that they are classified as fast ambulance craft, and has received NATO reporting name Ankang class, or 安康 in Chinese, meaning Well-Being. By Chinese classification, any naval vessel with displacement above a thousand ton is classified as ship / warship, and any naval vessel with displacement less than a thousand ton is classified as a boat / craft. Ankang class is the only boat / craft in the Chinese navy that is capable of hosting a helicopter, though it only has a landing pad, but not any hangar. A total of five units of this class have been confirmed in active service as of mid-2010s.
