A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes.
The Admiral Petre Bărbuneanu-class corvette is a series of four corvettes designed and constructed for the Romanian Naval Forces primarily for anti-submarine warfare. Only two corvettes out of a total of the four are still in service. Designed and constructed in the 1980s, they are a product of the Cold War with their armament and sensors based on Soviet designs. This class of corvettes was superseded by the Rear-Admiral Eustațiu Sebastian (Tetal-II) class.
A fast attack craft (FAC) is a small, fast, agile and offensive warship armed with anti-ship missiles, gun or torpedoes. FACs are usually operated in close proximity to land as they lack both the seakeeping and all-round defensive capabilities to survive in blue water. The size of the vessel also limits the fuel, stores and water supplies. In size they are usually between 50–800 tonnes and can reach speeds of 25–50 knots.
The Type 143 Albatros class was a German class of missile bearing fast attack craft. Each vessel is named after a bird of prey including the albatross, condor and cormorant. Constructed by German shipbuilders Lürssen and Kröger, the vessels were intended to replace the Type 141 Seeadler class. The German Navy retired the class in 2005 and sold the boats off to Tunisia and Ghana.
The Almirante Brown class is a class of warships built for the Argentine Navy. They were commissioned between 1983 and 1984, after the Falklands War. The class comprises four ships; Almirante Brown, La Argentina, Heroína and Sarandí. They are classified as either frigates or destroyers by different publications. The MEKO 360 type warships are based on modular designs which allow quick changes to the vessel's armaments depending on mission requirements. The modular nature of the construction also allows the ships to be modernized or refitted with greater ease. Six vessels were initially ordered, however two ships were cancelled and replaced with orders for MEKO 140 type hulls.
The Leeuwin class is a two-ship class of hydrographic survey vessels operated by the Royal Australian Navy (RAN). Leeuwin and Melville were ordered from NQEA Australia in 1996, and were commissioned in 2000. The ships are capable of charting waters up to 6,000 metres (20,000 ft) deep, carry three Fantome class survey boats, and can operate an AS 350B Squirrel helicopter. In addition to surveying duties, since 2001 both vessels have been used to supplement the RAN patrol force. Leeuwin and Melville are based at HMAS Cairns, and are active as of 2019.
NNS Aradu (F89) is a Nigerian frigate. She is the first of the MEKO 360 general purpose frigates built by the German Blohm + Voss company of Hamburg. The 125.6-metre ship is the largest in the Nigerian Navy. As a general purpose frigate, Aradu has capabilities for anti-air, anti-surface and anti-submarine warfare effectively, and participated in the 200th anniversary celebrations of the Battle of Trafalgar. The ship also possesses capability for naval fire support and electronic warfare. Additionally, she carries a ship-borne helicopter for anti-submarine warfare, search and rescue, and enhanced surveillance/detection.
The Yıldız class is series of two fast attack craft/missile boats of the Turkish Navy. They class was designed by Lürssen Werft of Germany and share the same hull layout as the preceding Doğan class. Both ships of the class were built in Turkey and entered service in 1996. They remain in service.
The Inhaúma class are a series of five corvettes operated by the Brazilian Navy. These ships were built in Brazil and designed with assistance from the German company Marine Technik. It was originally planned to build 12 to 16 ships but the economic situation in Brazil did not permit this and only five vessels were built. The first two ships were constructed at the Arsenal de Marinha in Rio de Janeiro, the second pair by Verolme. The programme was considerably delayed due to funding issues and the Brazilian Verolme yard's insolvency in 1991 which forced Júlio de Noronha and Frontin to be completed by Arsenal da Marinha. The first ship entered service in 1989 and the last in 2008. Three of the five ships have been taken out of service and one was sunk in a missile exercise in the Atlantic Ocean in 2016.
The P 4 class torpedo boat (TB) were aluminum-hulled torpedo boats of the People's Republic of China's People's Liberation Army Navy. Based on the Soviet K-123 hydroplane design, they were armed with twin 14.5-millimetre (0.57 in) machine guns, and two 17-inch (43 cm) torpedoes. This class is currently considered obsolete, but was not completely retired from active service, being placed in reserve until the mid-1990s.
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.
The Kuha-class minesweepers is a series of six inshore minesweepers of the Finnish Navy. The ships were constructed in 1974–1975. All the vessels of the class were modified and modernized in the late 1990s, including a lengthening of the hull. Two of the class were withdrawn from service in 2012. The rest of the class will be retired with the entry into service of the Katanpää-class mine countermeasure vessels.

The three strong class was the second generation of domestically built submarines, representing a significant improvement compared to the earlier Sutjeska class. Built at the Brodogradilište specijalnih objekata in Split, the new class featured a streamlined hull design and four bow facing torpedo tubes that could also be used for minelaying.
The Khamronsin-class corvettes are three corvettes constructed for the Royal Thai Navy in the late 1980s. Based on a British design, all three ships were built in Thailand.
