Portuguese Navy – Marinha do Portugal (Cold War)

The Marinha do Portugal reflected in part the rule of Salazar for several decades, including its involvment in colonial wars. After the carnation revolution in 1974, the navy was completelty rebuilt and modernized under a new doctrine. The transition was made in the 1980s and 1990s and today presents a part of NATO which is quite unique and interesting in its capabilities and location, albeit modest.
Portugal’s strategic position, and the fact that she eventually sided with the Allies during the Second World War, brought considerable benefits to her armed forces from the mid-1940s, in which the navy shared. Her fragile economy would not have supported a naval reequipment programme, but American aid started soon after the end of the war. In 1949, Portugal was a founder member of NATO and in 1951 she signed a treaty with the United States for establishing American bases in Portuguese territory, including the Azores. Warbuilt ships were transferred, but from the 1950s a modest programme of new building commenced.

THE COLONIES: In the 1960s, Portugal still had an extensive overseas empire, and most of her warships, including a large number of small frigates and patrol vessels, were designed to patrol their waters. India invaded and annexed the colonies of Goa, Daman and Diu on the Indian subcontinent in December 1961, and the Portuguese Navy lost a frigate and two patrol boats in a futile effort to prevent this. In the face of widespread unrest in the African colonies where independence movements sprang up in Angola, Mozambique and Portuguese Guinea (now Guinea-Bissau), the navy was hurriedly expanded to assist the other services. Large numbers of simply equipped small frigates, patrol boats and landing craft were built in a few years.

THE POST-COLONIAL ERA: The independence movements gradually won more and more territory. The end of Dr Salazar’s dictatorship appeared to change none of Portugal’s attitudes, but when his successor, Dr Caetano, was toppled by a military coup in April 1974, Portugal at last had leaders who were prepared to abandon the colonies and the drain they _ represented on the Portuguese economy and armed forces. The African colonies achieved their independence in 1974, 1975 and 1976, and most of the small craft built to serve in their waters were either transferred to Angola or Mozambique or scrapped.

PORTUGAL’S NAVY 1960s
A few medium-sized frigates were built in the 1960s to American and French designs, but the problems of the Portuguese economy have prevented any large-scale modernisation of these ageing ships and most of them are now suitable only for fishery protection duties. Many of the navy’s smaller vessels have been built in Portugal, but plans in the early 1980s to build new frigates locally were abandoned. Indeed, the acquisition of the three German-built MEKO 200 frigates in 1990 was possible only because a consortium of NATO countries provided 60 per cent of the funding.
In 1995, the Portuguese Navy had 15,000 personnel plus 2600 marines. In 1990 five Sea Lynx helicopters were ordered to form Portugal’s first seaborne aviation force. These are carried by the MEKO 200 frigates. Today, the Portuguese Navy counts 2 attack submarines,

The Portuguese Navy was a small, ageing blue water navy in 1939 (Poster). The The Portugal Navy in WW2 took no paert and stayed neutral, enforcing neutrality. The subject of the Portuguese Navy in interesting, perhaps more than some Scandinavian neutral navies. Indeed, despite its neutrality, the Country that fathered Vasco Da Gama and so many legendary seamen and merchants, had once the largest colonial empire worlwide. And as the latter was a shadow of its former self in 1939, the Portuguese Navy still had potentially to defend it. Technically it was in the XXth century a “pluricontinental nation with overseas provinces”. These were Cape Verde, São Tomé and Príncipe, Guinea-Bissau, Angola, and Mozambique in Africa and in African seas, Macao and Goa in Indian waters. If the first were not really a concern, patrolled by rivering gunboats but too far away to constitute an interest for the axis, Macao and Goa interested Japan in 1942. While Goa was invaded, Macao became a de facto protectorate during the war. The island was attacked later by the USN.

The Navy in the 1950-60s under Salazar

After World War II, Portugal was one of the founding nations of NATO, despite its regime, but this caracteristic was shared with its Neighbour, Spain under Franco. In the Cold War, the Portuguese fleet participated in the defense of the North Atlantic, dealing with the Soviet threat. Inside NATO it wa spushed towards proficiency in mine and ASW warfare. This was done in the context of colonial wars, in which the Navy took an important part.
The navy started with already existing ships that needed modernization and from the late 1940s many new vessels were transferred under MDAP: Nine frigates, three submarines, 14 patrol ships, 15 mine warfare ships. Naval Aviation was developed from 24 Curtiss SB2C Helldiver dive bombers which were used for many years as an ASW squadron. It was studied by NATO for other such initiatives. These were moved from Aveiro Naval Air Station to Montijo Naval Air Base.
In 1950, the Minister of National Defence and Chief of the General Staff were unified, which marked a common Navy-Army joint command.
There was however fierce opposition from naval aviators to in 1952, the Government placed the Naval Aviation under control of new newly automomous independent Portuguese Air Force. Its status thus became semi-autonomous. Naval Air Forces were fully integrated in 1958, and then disappeared by name and function, no longer a separate branch. Naval aviators and personnel either returned to the Portuguese Navy or joined the air force.
By 1962, the Portuguese fleet counted 16 ocean escorts (destroyers, frigates and avisos) as well as three submarines, 23 patrol vessels and 19 minelayers or all ranks. The Navy also had four survey vessels and a tanker as well as a buoy tender and a training ship.

From the late 1950s, however, the Portuguese Government started to account new external and internal threats in overseas territories and the naval forces were mobilized to carry and support the troops. On the other hand, commitment to European tasks needed a different type of navy and under NATO, an upgraded into modern anti-submarine weapons systems. So frigates, submarines and mine warfare vessels were needed in the North Atlantic. This came out off the new “Overseas” navy planned by the government. It was planned as a mobile intervention force with light aircraft carriers and assault vessels for a large Marine force. But budgetary speaking it went against NATO requirements for a fleet of specialized frigates and corvettes. There were accomodations to support small landing forces, but doubling as patrol ships. Guerrilla wars of the early 1960s needed also small vessels to operate on rivers and lakes in Portuguese Africa and argued for a third branch, a dedicated creation of brown-water navy counting many small patrol and landing craft.
This was accompanied by the ambition of a worldwide command, control and logistics capacity to adequately cover these Overseas territories. From 1957, Portuguese naval commands were created in Cape Verde (Angola), Mozambique and Goa (Indian Ocean) as well as in the Azores. Each had to manage its own area of operations, so the North Atlantic, South Atlantic and Indian Ocean. Each had its own local maritime defense commands and support facilities.
The Portuguese Navy also started to develop a global communications network with naval radio stations placed in all these Overseas territories. This this made the navy responsible for the long range inter-territorial radio communication and coordination with the Armed Forces.

Impact of the Colonial wars

The Portuguese Navy saw action in the cokd war at the occasion of two separate theaters, but both linked to its colonial history. After India was granted is independent postwar, the Indian Union soon vectored its attention on the lost colonial enclave in its territory, Goa. At the same time in Africa, in future Mozambique, Guinea and Angola, independence movements needed a large counter-insurrection operation.

Last stand in Portuguese India

At Goa, on the morning of 17 December 1961, the Indian Armed Forces attacked and invaded swiftly Goa, Daman and Diu. These three forces (land, air and naval) overwhelmed the local Portuguese forces. On the naval side only, the Indian Navy had an aircraft carrier plus two cruisers, eight frigates among others, against three small patrol boats, one in each of these enclaves. NRP Afonso de Albuquerque was based in Goa and barely seaworthy, she was used as coastal battery for Mormugao harbour and radio communications with Lisbon. Indeed the on-shore radio facilities were destroyed by the IAF in short order.

Afonso de Albuquerque fought the last naval gun engagement of the Portuguese Navy, at 12h00, 18 December against Indian frigates entering Mormugao harbour. Afonso de Albuquerque was ordered to sail out and engage these with its 120 mm guns. The duel lasted for an hour and after 400 rounds fire and many hits on two frigates, Afonso de Albuquerque herself suffered severe damage with 5 killed and 13 injured including the captain. Stranded, colors were struck and she was later evacuated by the crew, still under fire as no surrender sign was given.
The patrol boat NRP Vega in Diu on her side had no chance but face the Indian cruiser Delhi, with her only 20 mm gun. She maaged an Indian Vampire jet fighter however. But ue to this, the IAF then targeted her, until she was sunk,loosing two of her crew and captain killed, three injured.

War in Africa

The wars in Africa lasted for 14 years, 1961–1975 and had for consequence the carnation revolution, putting an end to the regime. The Portuguese Navy carried reinforcements, escorted transports, patroled and assaulted points in inland waters. The three territories in whic they operated were orders of magnitude larger than Portugal. These were Angola, Portuguese Guinea and Mozambique. In all three, amphibious missions of the Portuguese Marines multiplied, and the force was bolstered and ultimately divided between the Special Marines (fuzileiros especiais) and regular Marines (fuzileiros) mostly used to defend naval assets. The Portuguese Navy created for its strategy a brown navy as intended, made od countless small units, and that included both shallow draft patrol boats and landing craft, many designed and built in Portugal.

Angola

The Navy wa sbusy patrolling and protectinf the mighty Zaire River, avoid border infiltration of UPA/FNLA and MPLA guerrillas, coming from Congo (later Zaire). Again, many patrol and landing crafts were gathered in the “Zaire Flotilla” but the river was deep enough to admit occasionally frigates. The buggets workload was done by modest rubber boats though. Patrolling the Zaire River was so successful that the Portuguese managed to completely stopped the infiltration of the guerrillas and defeat thse forces, retaking Northern Angola, and managing to winning the war in the early 1970s.

Independence movements re-orientated their activity to Eastern Angola, supprted by neighboring Zambia. The Navy adapted and started establishing naval and Marine units some 1,000 km (620 mi) from the sea coast on the Zambezi, Cuando, Cuanza rivers among others. The same methods that prevailed on the Zaire were used against the MPLA and UNITA guerrillas and by late 1968, base was created at Terras do Fim do Mundo, with the creation of an entire city from scrtatch, “Vila Nova da Armad”. From 1970, the Portuguese Navy in Angola always had a frigate (rotations) available, as well as four large patrol ships, 11 patrol motor launches, 15 landing crafts and two Special Marine detachments as well as four Marine companies, five detachments.

Guinea

The country characteristics allowed the Navy to give a higher contribution to the global effort. Thanks to a large array of navigable rivers and the rest being marshy, allowed the Portuguese Navy to control directly most of the territory and its hinterland regions. There, Portuguese forces fought a movement called the PAIGC which was probably the best trained and equipped and matched the Portuguese, in such a way it left guerilla and started to resemble a conventional war.
The PAIGC organized even its own Navy with Soviet/Warsaw Pact and Chinese vessels. It featured notably at some point P 6-class torpedo boats, and countless small boats, and had the support of the Senegal and the Republic of Guinea, offering sanctuaries for training and equipping new units constantly. This sometimes gave them the occasion to launch direct attacks against the Portuguese garrisons and then withdraw cross border. Teting to avoid diplomatic incidents, the Portuguese Navy could not do much. It focused on logistical supporting scattered military units and bring on demand fire support to land forces, amphibious forces and Marine units.

Author’s illustration of the Coutinho class

The Portuguese naval presence in Guinea which started in 1964 received additional landing craft and a Sapper Divers unit o deal with naval mines laid by PAIGC forces. In 1971 General Spínola created two more “African Special Marines” detachments, with personnel recruited locally. One operation they led against the PAIGC forces was against Como island and other near islands in the southern Portuguese Guinea by January 1964. Portuguese Armed Forces launched Operation Trident, which was a major conventional joint operation using a great deal of ship based helicopters completed with amphibious assaults on a wide area, with islands covered by naval bombardments and air strikes. The Frigate Nuno Tristão was used as central command post for coordination, and the bombardment was led by the destroyer Vouga. The assault consisted of seven patrol boats, eight landing craft, three Special Marines detachement and an Army battalion.

In 1970 was also launched the secret Operation Green Sea (Operação Mar Verde), a raid on Conakry in the Republic of Guinea to quell this PAIGC sanctuary. Under Lt.Cln Alpoim Calvão (task force TG 27–2), the patrol boats Cassiopeia, Dragão, Hidra and Orion, landing craft Bombarda and Montante deployed and covered some 250 Portuguese Commandos and Special Marines plus 150 political opponents of the Guinean dictatorship. The night of 21–22 November saw the city captured, the Guinean Army neutralized, and the local PAIGC assets captured and destroyed, also rescuing 26 Portuguese POWs. This was quite a stuning success, ambeit many of the PAICG insurgents escaped, the movements was severely crippled.

Mozambique front:

In Mozambique, the Portuguese Navy moslty operated from the large Lake Nyasa, to deal with FRELIMO infiltrations from Tanzania. In this, the Portuguese were helped by the Military of Malawi. The Nyasa Flotilla was created to operate from Metangula naval base and others, and again, with Portuguese marines. The base was needed for large scale logistical operations resting on 12 patrol and landing craft operating from the port of Nacala to Lake Nyasa over 750 km inland.
The Portuguese Navy transferred many assets the Nyassa Flotilla and organized the supply of Portuguese Forces operating in Northern Mozambique using the sea to main logistical centers located in Lourenço Marques and Beira. With the construction of the Cahora Bassa Dam the FRELIMO guerrillas started operations in the Tete region by the early 1970s and the Navy reassigned assets to the Zambezi River.

From 1966, the Portuguese Navy maintained also in the Mozambique Channel always a frigates on rotation, deterring possible British naval forces actions in the neighbouting port of Beira or establish an oil embargo of oil to Rhodesia after its declaration of independence.
From 1971, three frigates or corvettes were present almost permanently plus a logistical support ship and three patrol boats as well as one landing craft, all in the Indian Ocean and five patrol boats plus seven landing craft in Lake Nyassa and three Special Marines detachments, three Marine companies.

ASW Frigate NRP Almirante Magalhães Correia fulfilling in from its NATO missons in the North Atlantic

Other tasks needed commitment at long-range of the Navy to ensure logistics to Armed Forces stationed in Cape Verde and São Tomé and Príncipe, as well as the Portuguese Timor and Macau.
The focus was to acquire many small riverine units to deal with colonial wars, and that was detrimental to NATO commitment, despite the compromises found in the ship’s uses. Still, the Navy was pressed by NATO to commit at least four capable ASW patorllers and ocean escorts, and still usable for landing operations. This led to the adoption of avisos, those of the Comandante João Belo-class, ordered from French yards (Commandant Rivière class). Portuguese Navy engineer Rogério d’Oliveira meanwhile received an order for really tailored coervettes, which became the João Coutinho-class. They were trumpeted at the time (1969) as the first truly modular ships in the world with large internal spaces usable for rapid reconfiguration for ASW or amphibious operations, and while being still cheap to operate.
This was the base for many frigates and corvettes built later. For its African operations, the João Coutinho-class had a small draft for coastal or large rivers operations, with full accommodations for a force of Marines and their equipments. Six were built, followed by four Baptista de Andrade-class (1973), improved.
To fulfill its NATO missions in the North Atlantic the Navy built specifically three Almirante Pereira da Silva class anti-submarine frigates. Built at Lisnave, Lisbon ENVC in Viana do Castelo, they were essentually a copy of the US Dealey class escorts. In addition, the Navy acquired four Albacora-class submarines. This was accompanied by the installation of COMIBERLANT in Lisbon. The Almirante Pereira da Silva-class frigates became a permanent fixture of STANAVFORLANT as soon as it was created.

The 1974 Carnation revolution and consequences for the Navy

On the early hours of 25 April 1974, young officers of the Portuguese Armed Forces launched the Carnation Revolution, which by contagion (convincing other branches and units of the military) overthrewg the Salazar regime without bloodshed. STANAVFORTLAND left the Tagus the first day of the Revolution, with the frigate Almirante Gago Coutinho. The latter was ordered by the Portuguese Navy Staff to leave the international formation and returned to face the Terreiro do Paço riverside square, where revolutionary forces massed. The captain was ordered to open fire on rebel armored vehicles but the crew after some debate, refused. Long sorty short in a bout the day or so, the old Salazar regime, which ruled over Portual for more than fifty years was deposed, and a new democratic one was setup.

The Frigate Almirante Gago Coutinho was ordered to fire on the army and crowd gathered at the Terreiro do Paço riverside square, like this Panhard EBR ETT.

This new regime was notably motivated by the idea of putting an end to colonial insurrection and grant independence to the concerned territories. Motivation behind the revolution came mostly indeed from disgruntled officers in Africa, seeing the sum of death and destruction with little progress. Negotiated ceasefires in Angola, Mozambique and Guinea and repatriation of all troops and Marines with the fleet was decreted. In no time, the independence of the Portuguese African territories was decreted. The first was Guinea-Bissau and last Angola, on 11 November 1975. The plethoral of former small boats of the local brown navy commands were transferred to these new nations. Thousands of Portuguese troops and civilians were repatriated, covered and escorted by the Navy. Task force FO 15 (with the frigates Hermenegildo Capelo and Roberto Ivens, corvette General Pereira d’Eça, tanker São Gabriel and hospital-ship Gil Eannes, troop transport ships Niassa and Uige) also repatriated troops, being the last to leave the continent from the bay of Luanda, with Vice-Admiral Leonel Cardoso (last Portuguese governor) at its head.

Portuguese authorities also started preparations for the independence of East Timor (ex-Portuguese Timor), which saw no guerilla and everything was done “by the book” and legalized, but after dispute between new Timorese political parties dgenerated, Portuguese governor Mário Lemos Pires fled to Atauro Island, off Dili by late August 1975. The Portuguese Navy then picked him up with the corvette NRP Afonso Cerqueira by early October 1975 and later NRP João Roby. On 7 December 1975, Indonesia, freshly independent too (from the Netherlands) invaded East Timor.
Portuguese authorities evacuated the area with a small detachment sent to Australia to continue patrolling Timor waters for a possible counterattack. But i never happened as the new reguime left the situation as it was in 1976. International response to what happened in East Timor was weak to say the least.
By the end of 1975, Portugal was left without colonies and its Navy was now refocused on the North Atlantic only, and the Warsaw Pact. It was also reshaped to care about the redefined Portuguese EEZ which at the time was still the 10th largest in the world thanks to a few remaining overseas islands.

In 1976, the Portuguese fleet’s bedrock was constituted of the four Comandante João Belo-class frigates, three Almirante Pereira da Silva-class frigates, six João Coutinho-class corvettes, four Baptista de Andrade-class corvettes, three Albacora-class submarines, ten Cacine-class patrol ships, four support ships and one training ship, and the few small patrol boats and minesweepers or landing craft repatriated from Africa. The latter were ill-suited for Atlantic Operations, leading to plan a fleet retrofit program with anti-ship and SAM missiles on frigates and corvettes, with funds obtained by selling all the vessels that were not necessary. However the new regime was also strapped for cash, having to modernize the country and reinvest in all what was neglected by the previous regime. The Almirante Pereira da Silva-class frigatesr were never modernized and were considered obsolete, retired in the early 1980s, but placed in reserve at the Lisbon Naval Base until decommissioned in the early 1990s.
In the 1980s the Navy counted on four frigates, ten corvettes, three submarine, ten patrol ships and few minor units. The staff realized its lack of offshore patrol vessels, leaving the corvettes and frigates to patrol for fishery protection and maritime search and rescue, and being rapidly worn out as the result.

Post 1990

From 1990, the Portuguese Navy started to be a more visible, less shady instrument of foreign policy, withing the frame of NATO and the UN. The Navy operated as part of larger elements and coalitions and with the Portuguese Army and Air Force, for peace keeping and humanitarian missions, using for these ships, helicopter or sometimes the special force marine detachments. In hot zones, they helped evacuating Portuguese nationals and other foreign civilians, notably from Sub-Saharan Africa. The mission in Bolama (Guinea-Bissau, 1990) as a good example as well as in Luanda (Angola, 1992), and Bissau (Guinea-Bissau, 1998-1999). The language helped them communicating with the locals, and they were present in many combat areas. There were many instances of the Portuguese Marines Special Actions Detachment retrieving civilians to frigates off-shore.

The Portuguese Navy also took part in international peace-keeping operations, also with the European Union forces.
In the mid-1990s, an intense modernization effort commenced, starting with the MEKO 200 (Vasco da Gama-class) frigates and Argos-class patrol boats. The Naval aviation was reborn with these new helicopter-capable ships, around a core of Westland Lynx helicopters.

The Portuguese Navy took part in the liberation of Kuwait in 1990–91, dispatching the logistics ship NRP São Gabriel to support the coalition in the Persian Gulf.
The Balkan wars, revolving around the Adriatic, saw the Portuguese Navy ative with a Frigate maintainin the arms embargo under UN and NATO, and dispatching DAE special forces between 1991 and 2000 to monitor the shores and traffic. A Portuguese commander once headed NATO Operation Active Endeavour in the Mediterranean by December 2001 and January 2002.
The Portuguese Navy also contributed to joint EU exercises and helping Spain to prevent illegal immigration and drug-trafficking from and around the Canary Islands. The Prestige oil-spill incident on Northern Spain saw its neihgbour sending frigates and surveillance aircraft to providing independent monitoring of the area.

On 7 June 1998 the was a military coup in Guinea-Bissau so the Navy had to mount a major naval rescue operations to protect its citizens and evacuate them as a civil conflict hitting residents. The rescue operation was codenamed Operação Crocodilo. Most were rescued and repatriated on board the merchant ship MS Ponta de Sagres.
On 11 June Captain Hélder Costa Almeida commanded Ponta de Sagres into the Port of Bissau under artillery fire to rescue above 2,200 civilians including 500 Portuguese. Another naval force was sent under command of Captain Melo Gome. It comprised the frigate Vasco da Gama, corvettes Honório Barreto, João Coutinho, and the support ship Bérrio carrying Special Actions Detachment and the 22nd Marine Company and support elements in Guinea-Bissau on 15 June. The Port of Bissau was secured to help evacuation of citizens and foreign nationals, and later along the coast of Guinea-Bissau via rubber boats and helicopters.

On 28 June, a ceasefire was signed between belligerents on board the frigate NRP Vasco da Gama. The operation was over on 21 July 1998.
They took part in the UN mission in Kinshasa (Zaire, 1997) and Congo (1998) asw well as East Timor (1999–2004) and under the UE intervention in the Democratic Republic of Congo in 2006, NATO counter-piracy mission off Somalia, SAR after the flooding of the Save River in Mozambique (2000).

A VBSS team leaves NRP Bartolomeu Dias, lead frigate of the Bartolomeu Dias class

With the East Timor’s independence from Indonesia in 1999, Portugal sent two frigates and troops to protect the country from a possible new invasion. NRP Vasco da Gama and NRP Hermenegildo Capelo made a stay by mid-2001 as a company of 155 Marines as UN peacekeeping force. From 2004, Portuguese Marines were attached to the Timor Military Liaison Group and Portuguese National Republican Guard contingent in Dili.
The Bartolomeu Dias-class frigates bolstered the fleet which needed modernization, as the Tridente-class submarines, launched 2010 of the state of the art U 209PN type. Local yards such as the Estaleiros Navais de Viana do Castelo (ENVC) built the next generation of OPVs, freeing former frigates from EEZ enforcement and fisherly guard, with the Viana do Castelo-class patrol vessels replacing the João Coutinho-class and Baptista de Andrade-class.
The Vasco da Gama-class frigates Álvares Cabral and Corte Real were present in Indian Ocean and were used as NATO task-force flagships off Somalia. In 2009-2010, a NATO fleet was under Portuguese command in the Gulf of Aden, being awarded from “exceptional bravery at sea” by the International Maritime Organization to RP Corte Real when the piracy was at its peak.
Another role of the Portuguese navy was scientific, in oceanographic and hidrographic. The first under the Hydrographic Institute used proper Hydrographic Ships such as the Dom Carlos I-class research ships to determine the Extension of the Continental Shelf of Portugal, solidified by 2004. The shelf was extended by 200 nautical miles, a claim submitted to the UN by 2009, pending validation.

In the 2010s, the Immediate Reaction Force was sent to evacuated Portuguese citizens, with a mixed naval force on the ready, based from Cape Verde in 2012 to intervene in Guinea-Bissau if needed after a military. This force could be deployed withing 45h, with a frigate, a corvette, a Marine company and sappers divers, mine warfare detachment and other units if available.
The Portuguese Task Group (PO TG) is another permanent structure with acrtive ships for a national autonomous capacity, capable of power projection, and to include submarines, ocean escorts, amphibious and logistical support ships spec ops and even hydrographic assets, mission-based. It still waiting for the acquisition of a landing platform dock ship. The PO TG had been already well demonstrated at INSTREX exercises.

Organization

National Maritime Authority

The NAutoridade Marítima Nacional supervises the Portugese coast guard and its tasks: Security, safety, figh-guarding, life-guarding, Pollution care, but also lighthousesmanagement and maintenance. Until 2014, its tasks were performed by the Navy, with a dedicated branch. Constitutional issues due to internal security roles led to devise a new branch separated from the Navy, and separate organization. Both it and the Navy still override their own competences in some aspects. The analogue of the Navy Chief of Staff is the National Maritime Authority but in sub-échelon, maritime zone commanders also heads maritime departments corresponding to territorial jurisdictions managed by the AMN.
There is also “Admiral AMN”. The AMN structure includes a Directorate-General and a Maritime Police. Sub-departments are the Life Guard Institute, Directorate of Lighthouses, Maritime departments, Port authorities, Maritime delegations, Sea Pollution, and the AMN School.
This organization manages its own ships also since 2014 (list below) although at first they were loaned by the Navy.

The actual Portuguese Navy

Current ships:

In the 2000s negociations led to the purchase of two-ex Karel Doorman class Frigates. In May 2006, indeed Portugal’s MoD under Luís Amado, showed interest in buying two Karel Doorman-class frigates and replaced two old João Belo class instead of two frigates Oliver Hazard Perry offered by the United States. A committee arrived in the Netherlands to evaluate the condition of two existing frigates to be bought. On 1 November 2006 MoD Nuno Severiano Teixeira signed a contract for the purchase of Van Nes and Van Galen. The first was transferred on 16 January 2009 and the second on 15 January 2010.
Class:
Bartolomeu Dias (F333), commissioned 2009, active service.
Dom Francisco de Almeida (F334) commissioned January 2010
Before these, They were already planned for acquisition as completed, of three frigates of the previous Kortenaer class already expected in 1982. Modified to Portuguese requirements. It was funded by a consortium inside NATO, the first planned to be built in the Netherlands and the two others in Portugal. But all was cancelled in August 1984. It was decided soon after to purchased MEKO 200 type Frigates to Germany instead.
These frigates are today in reinforcement of the three MEKO 200, NRP Vasco da Gama (F330) (In overhaul 2024), NRP Álvares Cabral (F331) and NRP Corte-Real (F332).
Only two older corvettes remained:

Portuguese Naval Aviation

The last major acquisition of this old corps, created in 1917, was in 1950, with the acquisition of surplus Curtiss SB2C Helldiver dive bombers through the MDAP (Mutual Defense Assistance Act). They were a dedicated anti-submarine squadron based at São Jacinto in Aveiro. These 12 Helldivers of the Aviação Naval Portuguesa were operated until the late 1950s. In 1951, the Naval Aviation tested at the Lisbon Naval Aviation Centre, a civilian Westland WS-51 Dragonfly Mk.1A helicopter to develop shipborne operations. It was was later sold to Italy and the Italian Air Force. After the unification of the Army and Navy services under the Subsecretariado de Estado da Aeronáutica, the Força Aérea Portuguesa (FAP)) created in 1952 integrated all former Naval Aviation assets, but they still formed a semi-independent branch for operations and training under the name Forças Aeronavais. By 1958 it was disbanded with technicians and officers returning to the Navy.
Until 1993, the Portuguese Air Force performed the tasks of Naval Aviation. These assets were based at Montijo Naval Air Station.

In 1964, the Guinean War saw a FAP Alouette II helicopter operated from a Portuguese Navy ship, for personnel transport and medical evacuation. The frigate Nuno Tristão for this had a makeshift wooden helipad built. Another was soon also based on the support ship Sam Brás.
Postwar, there were Alouette III operating from the deck of João Coutinho-class and Baptista de Andrade-class corvettes and support ship São Gabriel. In 1987, the modernization of the João Belo-class frigatespushed for a proper flight deck with telescopic hangar, until cancelled.

The Navy’s Helicopter Squadron (Portuguese: Esquadrilha de Helicópteros da Marinha, EHM) was created when the new MEKO 200 Vasco da Gama-class frigates were acquired from Grmany, as they included a built-in hangar and helipad. These helicopters were used for anti-submarine warfare.

These two ex-British ‘River’ class frigates, launched in 1943, were purchased by Portugal in 1948 and transferred in May 1949. Both were refitted in 1959 when their ASW armament was modernised. The Hedgehog ASW mortar on the forecastle was removed and the 4in (102mm) gun moved farther for ward. Two Squid ASW mortars (2 x 3) were then positioned side by side between the gun and the bridge.

Formoe was originally to have been renamed Zaire and Revnolds, Zambese, but when the two ex-USN ‘WGT type DE (launched 1944) were transferred under MDAP on 7 February 1957 they were actually renamed Cao and Real respectively.
Both had their 3x 21-in (533mm) TT removed, leaving an armament of 2x 5-in/38, 10-40mm AA (1 x 4, 3 x 1), 1x Hedgehog, 8 DCT, 2 DC racks. They were rated as frigates by the Portuguese.
The class comprised the ex-US JOHN C BUTLER class destroyer escorts (WGT type): F 333 DIOGO CAO (ex-Formoe), F 334 CORTE REAL (ex-McCoy Reynolds)
Builder: Federal Federal, Acquired 7.2.57 and 7.2.57.

Ex-British ‘Bay’ class AA frigates, launched in 1944-45. Cabral and Pereira were purchased in April 1959 and transferred to Portugal on 11 May 1959, and De Almeida and Da Gama were purchased in May 1961 and transferred after a refit on 3 August 1961. A half-sister, Alfonso de Albuquerque, ex-Dalrymple, ex-Luce Bay, built by Wm Pickersgill, launched 12 April 1945 and completed in 1949 as an unarmed survey ship, was purchased by Portugal in April 1966. She was employed as a survey ship and was stricken in 1983.

Pero Escobar had the same basic hull and machinery as the Italian-designed Venezuelan Almirante Clemente class, but had a considerably lighter armament to reduce topweight. She was modernised in 1968-69 to improve her AA and ASW armament, and was rearmed with 4-3in (76mm) (2 x 2), 2 Squid ASW mortars (2 x 3) and 6-12.7m (324mm) TT (2 x 3). She had MLT-3A and MLA-1B radar and SQS-29 sonar fitted, and this armament made her equivalent to the Da Silva class frigates. Pero Escobar was built to a NATO order.

These three ships were built in Portual to a slightly modified version of the US Dealey class DE design. The ships were fitted for prolonged service in tropical waters and they had 214.75in (375mm) Bofors ASW rocket launchers (2 x 4) in ‘B’ position in place of Weapon Alfa, plus 612.75in (324mm) Mk 32 ASW TT (2 x 3). The complement was 166 and they were fitted with MLA-1B search, Type 978 tactical, SPG-34 fire control and RM-316P navigational radars and SQS-30 (Da Silva), SQS-31 (Coutinho), SQS-32 (Correa) search, SQA-10A VDS_ and DUBA-3A attack sonar. They were built in Portugal under MDAP. Almirante Pereira (US DEALEY type) frigates were otherwise similar to the US Dealey class.

The Belo class are very similar to the French Cdt. Rivière, but are fitted for tropical service and have 2x 40mm/70 in place of the Riviere’s 2x 30mm (2 x 1). The Belos have a complement of 200 and have DRBV-22A search, DRBV-50 tactical, DRBC-31D fire control and RM-316 navigational radars, with SQS-17A search and DUBA-3A attack sonars. In the mid-1980s it was planned for this class to undergo a major refit, with one or both of the after 100mm turrets to be replaced with a helicopter deck and hangar on two ships, and with SSM on the other two, but this was abandoned due to cost. Instead, their ASW capability is to be modernised, in a programme due to complete at the end of 1995.
The Joao Coutinho class were designed by Blohm and Voss, Hamburg and built by them and by Bazan, Spain. They were relatively cheap and sparsely equipped light frigates, which could be acquired by Portugal in sufficient numbers to replace the old second-class sloops, corvettes, and gunboats. They can carry thirty-four marines, and their chief function until 1975 was patrolling off Portugal’s colonies.

There is provision for a light helicopter to land aft. As with the Belo class, a proposed modernisation including the fitting of SSM and SAM was cancelled for financial reasons. All ASW armament and sonar had been removed from the ships of this class by 1987, and the obsolete MLA-1B air-search radars had been replaced by a Kelvin-Hughes surface search set, more suited to their current role as fishery protection vessels. The De Andrada class utilised the same hull and machinery as the 7 Coutinhos, but had a more sophisticated armament and sensors. They have a helicopter platform but no hangar. After the withdrawal from the colonies, all four were to be sold to Colombia in 1977, but the deal was not completed. Lack of funds has prevented any modernisation plans for this class, and Baptiste de Andrada was placed in reserve in 1991, and Alfonso Cerqueira was stricken in 1994, Neither of these two classes is particularly well armed or equipped and are only really usable for coastal patrol or fishery protection duties.

The history of Portuguese plans for new frigates has been somewhat complicated. In 1982 it was expected that three frigates bascd on the Netherlands Kortenaer class and modified to suit Portuguese requirements would be built in a programme Vasco da Gama as completed On 25 July 1986 three MEKO 200 type fmgates were ordered from Blohm & Voss, Hamburg (one) and Howaldtswerke, Kiel (two). These were the ships finally chosen by the Portuguese Navy, after considering the Netherlands Kortenaer type (see above) and a Spanish proposal. The programme was 60 per cent funded by a NATO consortium comprising the USA, Canada, West Germany, Norway and the Netherlands. Similar ships have been built for Greece and Turkey.
These ships give the Portuguese Navy its first seaborne aviation capability, each carrying one Sea Lynx helicopter.

The Baptista de Andrade sub-class of the Coutinho class corvettes, were built for the Portuguese Navy by BAZAN in Spain in the 1970s. Yhey are an updated version of the João Coutinho class designed by Rogério de Oliveira and intended for overseas territories. The official record had them proposed to the South African Navy, with a delivery canceled after the Portuguese Carnation Revolution and due to be sold to the Colombian Navy in 1977 until the deal was scrapped. NRP Oliveira e Carmo was decommissioned in 1999, officially scrapped on 1 November 2007, later sunk as an artificial reef on 30 October 2012 NRP Afonso Cerqueira was decommissioned on 13 February 2015, sunk as an artificial reef off Madeira. Another was decommissioned in 2017 and the last is in limited service, pending replacement by the Viana do Castelo-class patrol vessels.

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 project for the construction of three frigates of this class was authorized by the Portuguese Government in 1985, five years after the request of the Portuguese Navy for the acquisition of new surface ships. According to Conway’s, 60% of the funding for these ships came from NATO military aid. Similar ships have been built for the navies of Greece, Turkey, Australia and New Zealand.
