A naval ship is a military ship used by a navy. Naval ships are differentiated from civilian ships by construction and purpose. Generally, naval ships are damage resilient and armed with weapon systems, though armament on troop transports is light or non-existent.

The ASW Continuous Trail Unmanned Vessel (ACTUV) is a DARPA funded project launched in early 2010 to develop an anti-submarine drone. ASW is an acronym for Anti-Submarine Warfare. In January 2018 after successful sea trials it was announced that the "Sea Hunter" prototype has transitioned from DARPA to the Office of Naval Research for further development.

A barracks ship or barracks barge or berthing barge, or in civilian use accommodation vessel or accommodation ship, is a ship or a non-self-propelled barge containing a superstructure of a type suitable for use as a temporary barracks for sailors or other military personnel. A barracks ship, a military form of a dormitory ship, may also be used as a receiving unit for sailors who need temporary residence prior to being assigned to their ship. The United States Navy classes them as either Auxiliary Personnel Barracks (APB) or Auxiliary Personnel Lighter (APL).

Ghali, gali or gale are a type of galley-like ships from the Nusantara archipelago. Several native galley-like ships already existed in the archipelago, some with outriggers. The design of ghalis is the result of the impact made by Mediterranean shipbuilding techniques on native shipbuilding, introduced particularly by Arabs, Persians, Ottoman Turks, and Portuguese. The terms may also refer to Mediterranean vessels built by local people, or native vessels with Mediterranean influence.

Ghurab or gurab is a type of merchant and warship from Nusantara archipelago. The ship was a result of Mediterranean influences in the region, particularly introduced by the Arabs, Persians, and Ottoman.

A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies.

The heavy cruiser was a type of cruiser, a naval warship designed for long range and high speed, armed generally with naval guns of roughly 203 mm (8 inches) in caliber, whose design parameters were dictated by the Washington Naval Treaty of 1922 and the London Naval Treaty of 1930. The heavy cruiser is part of a lineage of ship design from 1915 through the early 1950s, although the term "heavy cruiser" only came into formal use in 1930. The heavy cruiser's immediate precursors were the light cruiser designs of the 1900s and 1910s, rather than the armoured cruisers of the years before 1905. When the armoured cruiser was supplanted by the battlecruiser, an intermediate ship type between this and the light cruiser was found to be needed—one larger and more powerful than the light cruisers of a potential enemy but not as large and expensive as the battlecruiser so as to be built in sufficient numbers to protect merchant ships and serve in a number of combat theaters.

A juanga or joanga refers to large-sized kora-kora, karakoa and lanong. They are used all throughout the Philippines and Eastern Indonesia, in Maluku smaller versions existed. They are propelled by oars but are not used for carrying cargo.

HHMS Kaimiloa was the first and only ship of the Hawaiian Royal Navy. The ship was formerly the Explorer, a 170-ton schooner, built in England in 1871. Kaimiloa sailed from Hawaii to Samoa and other Pacific islands in 1887 in an effort by King Kalākaua to form a confederation of Polynesian states to counteract European imperialism. The instance nearly resulted in military conflict between the Kingdom of Hawaii and the German Empire, who viewed Samoa as their possession in the Pacific. It was also used as a training ship.

Knabat bogolu is a type of traditional war vessel from Mentawai islands, west Sumatra, Indonesia.

A kora-kora or kora kora or coracora is a traditional canoe from the Maluku (Moluccas) Islands, Indonesia. They are naval boat for carrying men on raids for plunder or for slaves. In Maritime Southeast Asia, raiding for slaves was an honourable way of making a living, and the kora kora was needed for defence against raids as well as for forays. Large kora-kora is called juanga or joanga.

Kotta mara is a type of floating battery or fortified raft from Borneo. It is used by native Bornean in warfare, its usage rose prominently during the Banjarmasin war (1859-1906). Kotta mara is used in riverine warfare, as an armed vessel or simply a blockhouse or fortification to prevent enemy advance in the river.

A mother ship, mothership or mother-ship is a large vehicle that leads, serves, or carries other smaller vehicles. A mother ship may be a maritime ship, aircraft, or spacecraft.

A fleet or naval fleet is a large formation of warships - the largest formation in any navy - controlled by one leader. A fleet at sea is the direct equivalent of an army on land.

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 below, and a 3-inch (76 mm) or 4-inch (102 mm) gun in the bow equipped the trawler for anti-submarine duties.

A reserve fleet is a collection of naval vessels of all types that are fully equipped for service but are not currently needed and thus are partially or fully decommissioned. A reserve fleet is informally said to be "in mothballs" or "mothballed"; an equivalent expression in unofficial modern US naval usage is "ghost fleet". In earlier times, especially in British usage, the ships were said to be "laid up in ordinary".
