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.
A shipyard, also called a dockyard or boatyard, is a place where ships are built and repaired. These can be yachts, military vessels, cruise liners or other cargo or passenger ships. Compared to shipyards, which are sometimes more involved with original construction, dockyards are sometimes more linked with maintenance and basing activities. The terms are routinely used interchangeably, in part because the evolution of dockyards and shipyards has often caused them to change or merge roles.
A patrol boat is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine, estuarine, or river environments.
The Brazilian Navy is the naval service branch of the Brazilian Armed Forces, responsible for conducting naval operations.
The Portuguese Navy, also known as the Portuguese War Navy or as the Portuguese Armada, is the navy of the Portuguese Armed Forces. Chartered in 1317 by King Dinis of Portugal, it is the oldest continuously serving navy in the world; in 2017, the Portuguese Navy commemorated the 700th anniversary of its official creation.
The Vasco da Gama class is a class of frigates of the Portuguese Navy. Named in honor of the Portuguese explorer Vasco da Gama, the ships are based on the German MEKO 200 design, and are Portugal's major surface ships. Portugal operates three ships of this class, which were built in Hamburg by Blohm + Voss (B&V) and by Howaldtswerke-Deutsche Werft (HDW) in Kiel, using modular construction techniques.
The Algerian Naval Force is the naval branch of the Algerian military. The naval force operates from multiple bases along the country's nearly 1,440 km (890 mi) coastline, fulfilling its primary role of monitoring and defending Algeria's territorial waters against all foreign military or economic intrusion. Additional missions include coast guard and maritime safety missions as well a projection of marine forces. Algerian forces are an important player in the Western Mediterranean.
Goa Shipyard Limited (GSL) is an Indian Government owned ship building company located on the West Coast of India at Vasco da Gama, Goa. It was established in 1957, originally by the colonial government of the Portuguese in India as the "Estaleiros Navais de Goa", to build barges to be used in Goa's growing mining industry, which took off after the establishment of India's blockade of Goa in 1955. In the wake of Portugal's defeat and unconditional surrender to India following the 1961 Indian annexation of Goa, it was requisitioned to manufacture warships for the Indian Navy and the Indian Coast Guard.
The Viana do Castelo class is a class of offshore patrol vessels planned by and for the Portuguese Navy, as a result of the NPO2000 Project, that are being constructed in the West Sea Shipyard.
The Espora-class corvettes are six warships of the Argentine Navy built in Argentina to the German MEKO 140A16 design, this in turn being based on the Portuguese João Coutinho-class project. The first entered service in 1985 but accidents and lack of funds meant the last was not completed until 2004. The ships currently form the 2nd Corvette Division of the Argentine Navy and their home port is the Puerto Belgrano Naval Base. Although considered by its designers to be frigates, the Espora-class vessels have been classed in Argentina as corvettes.
The João Coutinho-class corvettes were a series of warships built for the Portuguese Navy for service in Portugal's African and Indian colonies. Initially rated as frigates, they were downgraded first to corvettes and then patrol vessels with age. They were designed in Portugal by naval engineer Rogério de Oliveira, but the urgent need of their services in the Portuguese Colonial War meant that the construction of the ships was assigned to foreign shipyards. Six ships were built; the first three ships were built by Blohm & Voss and the remaining three by Empresa Nacional Bazán. The ships were launched in 1970 and 1971. The relative cheap cost of the design led to it being the basis of several other classes in other navies. From 1970 until the end of the conflict in 1975, the corvettes were used for patrol and fire-support missions in Angola, Mozambique, Guinea and Cape Verde. After the African colonies gained their independence, the corvettes were assigned to patrol duties in Portuguese territorial waters.
Estaleiros Navais de Viana do Castelo (ENVC) is a medium-sized shipyard in business since 1944, located in the town of Viana do Castelo, on the Atlantic Coast in the very north of Portugal. Occupying an area of 400,000 square metres and employing 625 people, it is a major Portuguese shipbuilder. In 2013 its assets and operations are sub-licensed to Martifer.
The Centauro-class patrol boat is a series of four patrol boats in service with the Portuguese Navy. It is an evolution of the preceding Argos class. This class is meant for fisheries inspection and control duties mainly in the Mainland Portugal shores – with some sporadic presence in the Madeira Archipelago. The Centauro class is Portuguese-designed and built at the Arsenal do Alfeite (Almada) and Estaleiros Navais do Mondego.
The Lisbon Naval Base, is the main installation and operational base of the Portuguese Navy. Located at the former Royal Estate of Alfeite on the south bank of the Tagus river's estuary, near the city of Almada, the installation is sometimes referred to as the Alfeite Naval Base.
The Tamandaré class is a class of future stealth frigates for the Brazilian Navy, based on the MEKO family of warships. The project is being developed by the Ministry of Defence and the Águas Azuis consortium, composed of ThyssenKrupp Marine Systems and Embraer Defense & Security. The construction of the four planned frigates started in 2022 and are scheduled to be delivered between 2024 and 2028.
