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. Finnish Navy vessels are given the ship prefix "FNS", short for "Finnish Navy ship", but this is not used in Finnish-language contexts. 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.
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 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.
The Battle of Someri took place in the Gulf of Finland during World War II on 8–9 July 1942, between the Soviet Union and Finland. Starting as a modest operation to clear a Finnish observation post from a small island, it became one of the largest surface ship engagements in the Baltic theater.
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.
Surface flotillas of the Kriegsmarine were organizational groupings of German naval vessels during World War II based on class of vessel and geographical location. Surface flotillas were not operationally deployed units, but functioned through the administrative command chain of the Kriegsmarine.
Type 8105 naval trawler is a Chinese auxiliary ship of the People's Liberation Army Navy (PLAN). Type 8105 along with Type 792 and Type 8154 naval trawlers have all received NATO reporting name FT-14 AIT class, meaning Fishing Trawler - 14 Auxiliary Intelligence-gathering Trawler. After retiring from their original role of a spy ship, Type 8105 naval trawlers have been converted to auxiliary minesweepers and survey vessels, and kept in operational reserve of the Chinese navy.
Type 792 naval trawler is a Chinese auxiliary ship of the People's Liberation Army Navy (PLAN), deployed as intelligence gathering spy ship. Type 792 and its predecessor Type 8154, along with Type 8105 naval trawlers have all received NATO reporting name FT-14 AIT class, meaning Fishing Trawler - 14 Auxiliary Intelligence-gathering Trawler.
