Spanish Navy (Cold War)

spanis navy The Armada 1947-1990, About 160 ships.

The Spanish Armada under Franco was very much the same as in 1939 and was closely linked to the economical and political context. A modest programme was visited in 1944, but a more ambitious one was possible in 1953 after signing with the US the 10-years MDAP treaty. Despite of this, Spain only became part of NATO in 1982 as a 16th member, and only gradually, with full membership in 1992. The Principe de Asturias became the most visible flagship of the Armada at that time (she was launched in 1982) while in the 2000s Navantia gained traction by exporting its Juan Carlos I LHD (Australia and Turkey) and the Álvaro de Bazán class is today an AEGIS destroyer masqueraded as a frigate. These forces constitutes for Spain a blue water navy, covering for NATO the southern Atlantic sector.

Spain in the early cold war: From outcast to ally

Before going into more details, let’s cover the situation of Spain when the cold war started: The Armada at that time was pretty much the same as of 1939, but in between, the civil war had left big scars to the country, with more than 500,000 lives lost and many more forced to exile, many to escape political repression or even executions. To add to the material destructions, WW2 completed the demolition of the trade fleet, and left a country impoverished, excluded from any postwar help. A costly isolation out of the UN, and for the US the sole consolation Spain was staunchly anti-communist and should be considered an ally. Negotiations in that sense went on, despite the ambiguous position of Spain in WW2: Sending the Azul Division on the eastern Front breeching its neutrality, and Stalin’s insistence to invade Spain in 1945, rejected by Churchill and Truman.

Later, Stalin vetoed any attempt to integrate Spain to the UN until his death in 1953. At the Potsdam conference it was firmly declared to isolate Spain diplomatically and economically, perhaps hoping for a dramatic change inside the country. The “Spanish question” was one of the early and though challenge of the fledging United Nations, and both USSR and Poland pushed for a UN-backed military intervention. Of course, the US wanted to avoid a communist takeover of Spain, as already strong results of the communists in France’s first postwar elections threatened too the whole balance of influence in western Europe. France advocated to severe diplomatic relationships with Spain instead of an intervention. UN Resolution 39 (Dec. 1946) validated this. The only six countries which opposed it were in Latin America, including Argentina, it’s biggest supporter in the UN. Some countries left their ambassador in place, like Portugal, which had obvious trade relations with Spain. Franco; aware of his lack of legitimacy, drafted a referendum in 1947, putting in the same basket the return of the monarchy and securing his position for life. It was understood that the Monarch would elect a new government in the case Franco died or resigned, which happened in 1975 (see later).

Rota naval base, in Andalucia, on the southern Atlantic coast. Upgraded massively from 1953 and now covering more than 6,000 acres (24 km2), on the northern shore of Cadiz. Already a strategic post for centuries and Spanish naval base, it was radically upgraded and upsized to host USN task forces and an air base for heavy duty planes, such in the 1960s KC-130 stratotankers, B-52s and C5 Galaxy among others. Chief of Naval Operations deployed Submarine Squadron 16 (SUBRON 16) to Rota on 28 January 1964 with USS Proteus while USS Lafayette completed its first Fleet Ballistic Missile deterrent patrol, refit and replenishment from Rota. Ats its peak size (early 1980s) NAVSTA Rota comprised 16,000 sailors, naval personal and their families, and was home to two permanently forward deployed aviation squadrons, VQ2 and Fleet Logistics Support Squadron 22. A patrol squadron of P-3 Orion operated there and between Lajes Air Base in the Azores, to track Soviet naval vessels and submarines. It declined in the coldwar despite a use in 1990’s gulf war, and in 2011, US Secretary of Defense Panetta announced four Aegis warships would be stationed at Rota to bolster the missile defense of NATO as part of EPAA.

In between, Spain went on trading massively with Argentina and the USA; The latter went on selling food and oil, while the country tried to established stronger relation to other countries in South America and the middle east. Spain recoignised the arab league in 1946 and pushed its support of Jordan in its war against Israel. In 1949, in recoignition, King Abdullah of Jordan would be the world’s first head ot state to visit Spain. The 1947 Truman doctrine logic natually enticed the restoration of relationships with Spain. In 1950 was voted a massive aid of 62.5 million dollars in aid through US banks. Later both the Arab league and Latin american countries obtained the vote of a new UN resolution brining an end of the sanctions inflicted to the regime, the same year, which passed because of its strong backing from the US. From then on, despite Soviet protests, Spain was allowed to join the UN (but yet not as a member) and its agencies while diplomatic relationships were restored. In 1953 was signed the Concordat with the Vatican whereas Spain joined other organizations, the pact of madrid with massive military aid from the US (which also included MDAP and construction of military bases in Spain, notably at Rota NB, Morón AB, Torrejón AB, and Zaragosa AB), and the death of Stalin ultimately allowed to envision full membership with UN, which was secured in 1955.

In 1966, a B-52 from Morón AB crashed in Palomares, releasing four nuclear bombs in the area. They detonated upon impact, but not trigerring the nuclear reaction, although one resulting in the contamination of a 0.77-square-mile (2 km2) area by plutonium. Another fell in the Mediterranean. This was perhaps the price to pay for Spain to be “part of the club” again.

The start of the cold war and altitude towards the communist block (which supported and recognised the now defunct republic), allowed Madrid to play its only card: Rapprochement with the West, despite being until then ostracised by nearby democracies. To give some clues of a future change of regime, Franco started to relax and slightly release its grip on power, discarding the Falange, implementing a set of reforms with a law on personal freedom, and promising more importantly a return to the Constitutional Monarchy. However the economical situation was definitively not liberalized, still under the strict control of the state, and stagnant, until reforms were passed allowing the return of private investments, followed by international investments, crowned by the US aid act of 1953 (and signature of the MDAP). This was signalled by the installation of four US naval air bases in Spain, Franco regaining some respectability on the global sphere. However deep changes were postponed until the Caudillo’s death in 1975, with most of the WW2 Armada.

In 1947 the Spanish fleet comprised the following:

-Cruiser (modernized) Navarra (1920), discarded 1956.
-AA Cruiser Méndez Núñez (1922), pennant C 01, modernized as such in 1947, discarded 1963.
-Three Cervera class cruisers (1925-28), pennants C 11-C 13: Galicia, Cervera, Cervantes, partially modernized, discarded 1963-70.
-Canarias, heavy cruiser (1931), partially modernized (radar, AA), pennant C 21 discarded 1975.
-3 Alsedo class (1922), discarded 1957, no pennant.
-12 Churucca class (1926-33), pennants D 11-41, partially modernized, stricken 1957 to 1970.
-2 Alava class (1946), just completed, pennants D-21 and 23 (see later).
Also discarded in 1949-53 were the two ex-italian large destroyers leaders of the Poerio and Aquila classes: Huesca, Teruel (1914), and Ceuta, Mellila (1919).
Gunboats and Minelayers
-3 Castillo class ships, and Calvo Sotello (1922, 1934) discarded 1953-57, no pennant.
-4 Jupiter class (1935), pennant F 01, 02, 11, 12: Discarded 1970-77.
-2 Eolo class (1939), pennant F21, 22, discarded 1972.
-8 Pizarro class (1944), completed 1946-47, Pennants F 32-42, stricken 1968-82.
-C2 (1928) was discarded in 1952, the two ex-Italian General Mola and Sanjurjo in 1959 and the German G7, ex-U 573, in 1970.
-D class (1944): Completed after the war, D3 was even launched in 1953, discarded 1965-71 after some modernization (streamlining).

To this, we can add the Bidasoa class minesweepers, seven vessels ordered in 1944 and partially completed post-WW2. They were given the pennants M01-06 (but one lost in 1954) and discarded 1971-72. Also were quickly discarded three ex-German S-2 type S-Boats LT11-14, LT-21-26 of the S 73 group, and ex MAS LT-17, stricken between 1947 and 1952. Also many patrol ships, fishery protection vessels, coast guards and custom ships, harbour duty vessels were also discarded in the post-war years.

1950s completions

The 1944 naval program was calling for a modernization (a reconstruction) of the Mendez Nunez as an AA cruiser,the completion of the fourth group of the Churruca design, authorization of the four Oquendo class, and Audaz class Torpedo Boats, laid down a year later in 1945, despite the type was completely obsolete. From 03/08/1944 were also launched a serie of Pizarro class gunboats, which can be used for a variety of tasks. Also in May 1944 was launched the first of the new three D-class submersibles with a German design. In September, a serie of seven Bidasoa class minesweepers, also based on the German M-Type were launched. They were all completed between 1947 and 1955, but considerably bolstered the fleet after the losses of the civil war. They also formed the bulk of the Armada until Spain started to be opened again “for business”, benefiting from some influx of Western tech and US transfers to modernized the fleet under MDAP. The latter was signed on 1953, and was valid for ten years. This proved invaluable at rejuvenating the Spanish Navy.

Spain and NATO

Spain was largely seen viewed as a backwards outcast in Europe at the time, of the UN as well, and not only the country was excluded from the Marshall plan, to the detriment of its economy, but Spain only started a rapprochement with NATO from 1986, before being accepted as a full member in 1992, so after the cold war. Despite of this, scenarios of a third world war included at some point or another Spain, and the US could not ignore this. But in ten years, Spain made the transition from an international paria to a recoignised UN member, staunch ally of the USA, and key member of the anti-communist alliance.

Spain had a limited Atlantic reach on its north-west corner, and the Bay of Biscaye, but could control access to the Mediterranean via Gibraltar, still a British enclave which could have been taken if needed. Spain stayed neutral during the whole cold war, but it’s political position towards the North Atlantic Organization was rather favourable, as communist elements has been purged from the society and its position towards USSR was easy to guess in case of conflict.

These were highy versatile ships, usable as frigates and gunboats. Two units of the class, Vicente Yáñez Pinzón and Legazpi were included in the 1955 Modernization Program. They were rebuilt as ASW frigates still retaining good AA capabilities to be used as esccorts and self-defence, and used US fire direction systems. They operated from Ferrol until the Baleares class frigates came into service.

In case Soviet tanks were unleashed in the plains of Germany, and not stopped (putting aside the use of tactical nukes), would it have been in any interest for Soviet Tanks, after taking out France, to veer south to the Pyrenees ? Crossing the latter was already a thing, and it’s certain there was a strategic interest at securing Gibraltar, but this implied a crossing of the whole peninsula, with rugged terrain not always favourable to tanks. At first, the black sea fleet would have to deal with the Turkish, Greek, Italian and French Navies, in addition to the Royal Navy and a permanent USN Task Force, before even contemplating attacking the Spanish Mediterranean fleet. And the ratio were not very favourable to the Soviets.

By contrast, Portugal was integrated into NATO in 1949. It only had an Atlantic reach, but its membership had always been crucial to establishing air bridges between both sides of the Atlantic. The Portuguese fleet also was vital to guarantee sea-trading lines. The Azores and Madeira formed a strategic triangle with mainland Portugal and the islands would have been od strategic importance for refuelling facilities, track submarines and made surveillance or communication assistance. IBERLANT Command was established in 1967 in Portugal, the southernmost command in the Atlantic, strongly connected to the Allied Command Atlantic (Norfolk, Virginia) at the hinge between Europe and North America, to the Tropic of Cancer, covering 1.150 km seaward from the Strait of Gibraltar, with the task of covering 600.000 square miles of ocean crossed by many shipping routes and sea lanes.

New programmes of the cold war

1950-60s programmes and MDAP

The signature of the the MDAP between the US and Spain started an unprecedented boom in naval capabilities, bolstered by recent ships, like the Roger de Lauria class, destroyers clearly inspired by the Gearing, of which five, plus five Fletcher-class, entered service in the 1960-70s. Another sizeable transfer was the Aircraft Carrier Dedalo, ex Independence class USS Cabot. Naval estimates doubles between 1954 and 1961, personnel increased from 36,000 to 42,000 while modernization of 30 Spanish ships went on until 1963, with new AA, ASW and electronics concerned the Alava class DDs, Audaz and Pizarro class Frigates, Jupiter class, Atrevida class corvettes, and Almanzora class minesweepers and two D class submarines. The old Churruca class destroyers were even considered for modenrization but this was ruled out for more USN transfers and new construction programmes. Negociations started with the British for the construction of four Leander class frigates, and Oberon class submarines. At that time indeed, Spain was anxious to procure non-American experience and equipments. Radars for the Oquendo class were indeed provided by UK, but tense relationships with the Peninsula and an unfavourable press and parliament killed negociations in 1964.

The ASW Frigate Diana (F-32)

Ultimately, ordered went back to the USA, and in alternative to UK, France, notably for its submarines, but many other military materials as well (such as tanks). Agreements were signed in 1966 for licence-construction, which was way cheaper in Spain rather than purchasing ships abroad. This concerned five modified Knox-class and two (+3 in option) Daphne class SSGs. In 1975, the Armada had bold plans, including two aircraft carriers (Dédalo and Asturias), 2 cruisers (modernized Canarias and Galicia or possibly one acquired from the US), eight destroyers, 12 Frigates, 8 submarines, 60 minesweepers, 100 auxiliaries plus 27 ASW patrol planes and 48 ASW/SAR helicopters. This plan was partly realized. The first step in 1967 was the acquisition of the ex-USS Cabot (Dédalo), while plans for another design to be built in Spain were started. To save time and money, a USN design called the US sea control ship type, rejected by the Congress, was chosen. But the program that would be the Principe de Asturias carrier would take ten years to completion and eventually ended as replacing Dédalo instead of making a two carrier force.

From 1973, Dédalo had much increased capabilities with the adoption of AV8-S matador VSTOL aircraft, ordered from the US Marines and delivered in 1976-81. The USN also agreed in August 1970 to transfer two submarines (Balao class), five destroyer (Gearing FRAM), four ocean minesweepers, and four tank landing ships, the last transferred in October 1973. There was another agreement in 1976 for the transfer of four more ocean minesweepers and a repair ship, not carried out. Meanwhile a January 1973 nava plan was annouced, with one light cruiser, three guided missile destroyers, ten corvettes, two subs (agosta class), PF and patrol crafts. Budgetary problems ensured that the light cruiser and guides missile DDs were deferred to 1977, then to 1978 and changed in nature as opportunity made changing the light cruiser to a light aircraft carrier instead while the destroyers became USN FFG 7 Frigates. The Armada’s goal was to have two task forces, one always at sea. Each was centered around a light carrier, one cruiser, four missile frigates, two tripartite minesweepers, tenw corvettes and two subs. This led to the second naval program from 1983 (see later).

Meanwhile, The death of Franco in 1975 changed Spain a great deal. The King of Spain, Juan Carlos I, was prepared to take the succession of Franco, but instead of following the same conservative path chose to open Spain to Democracy. In 1978 Spain ratified a new constitution, and was now a newly free democratic state. The United States had pledged the new government their support, which was limited until then by MDAP to Five ex-Fletcher class destroyers from 1957, and armaments on the Oquendo and De Lauria class destroyers. The tip of the whole program was Spain’s first modern capital ship, laid down in 1979 at Ferrol: The Principe de Asturias a small but capable aircraft carrier, later also adopted by the Thai Navy. At the same time, the fleet comprised Fletcher-class ships and six Perry-class Frigates, a reflection of the long run an strong collaboration of Spanish Naval Yards with US yards.

1980s naval plans

The next phase of construction was planned for 1983-1990, basically covering the end of the cold war. Outside the Asturias, two cruisers were still planned, eight more frigates (likely enlarged Descubierta class), two more minesweepers but also 10 Matador VSTOL, six patrol and four ASW planes. Budgetary constrains, again, crippled this to just two destroyers, seven frigates, minehunters and a support ships plus PBs. It was extended FY 1995 to include three subs and two missile DDs of the Spruance class, four FFG-7 and three Type 552/A (Mod. Descubierta), but also six FACs, 13 minehunters, LPD, LSTs, and OSVs. The Spruance class were dropped but instead impressive Álvaro de Bazán class, classed as Frigates but in reality AEGIS missile destroyers were built. Budgetary conditions from 1986 partial integration in NATO urged for military spendings of 2% of GNP, however the Navy took 30% of the total defence budget instead of 20% previously. The 1988-96 plan proposed five NATO NFR 90 AAW Frigates instead of two more subs.

Ultimately in 1989 the last cold war Spanish naval plan was drafted, called the Alta Mar plan (‘High seas’). It was established until 2002 but was recast in 1990 to include replacements for the Gearing FRAM DDs, with four F-100 Frigates (first active in 1998) and five F-110 Frigates to replace the Baleares class. Actually Spain was the last to drop the F90 Frigates project. The plan also planned the modernization of two Agosta-class subs before the new Scorpene class could be started. Most of deliveries were planned for 1994, but the post-war years announced a world economic recession and the Alta Mar Plan was soon in trouble, with cancellations and slips in schedules, notably for the FFG-7 Frigates (OH Perry class), and more crucially, the F 100 Frigates, delayed until the 2000s, while the first Spanish LPD was started by Navantia, and will prove to be quite an export success in the 2000s.

The effort of the Navy did not to enter the bargaining game, with exaggerate dangers or threats and what was achieved was remarkable nevertheless:
-The capacity of the amphibious force was more than doubled, compared to what was planned.
-The capacity of the auxiliary vessels was doubled.
-The displacement and armament of the F-100 was doubled, or even more (They are equivalent, but bettern to the Spruance class once planned).
-The air fleet was increased with moden SH-60s and NH90s.
But above all the acquisition of a second platform multipurpose ship, albeit not a natural aircraft carrier, was enough to replace the Prince of Asturias when in maintenance. Certainly the aforementioned increases still did not raised the Armada to the same level as Great Britain or France but it could be measured against that of Italy or Germany. The chief Admiral in front of the Congressional Defense Commission in 2006 declared that the Spanish Navy whad redeemed the specter of the 1898 war and the poor reputation that followed.

FFG-7 Frigate
The most ambitious part of the PAM (Alta Mar Plan) was trying to surpass what had been achieved with the Santa Maria class, F-80 frigates (here) and to build even more efficient ships.

As of 2018, circa 138 vessels were in service in the Armada, including minor auxiliaries. Assault ship & aircraft carriers, missiles frigates, large and small, amphibious transport docks, corvettes, submarines, mine countermeasure vessels, patrol vessels and other auxiliaries goes for a total displacement approximately of 220,000 tonnes.

Spanish Marines:

The Marine Corps is probably the most ancient in Europe, going as far back as 1537. One of the most famous of Spanish Marines was without a doubt Miguel de Cervantes, wounded at the climactic battle of Lepanto. Its motto still is “Per Terra et Mare” (“By Land and Sea!”). It was involved, Outside Lepanto and countless small engagements, in the War of Jenkins’ Ear, the Siege of Pensacola, the Spanish–American War, Rif War and Spanish Civil War. It was reformed at first in 1717 as the Cuerpo de Batallones de Marina, while the specialized Real Cuerpo de Artillería de Marina was created in 1833, later abolished in 1857. In 1879 the Academia General Central de Infantería de Marina was founded.

Batallones Expedicionarios were used in several colonial wars. Discredited by the Battle of Gallipoli during WWI where naval assault showed its limits, the Marines deployed in Morocco, despite their success, were soon described by the political left in Spain as a leftover of the Spanish colonial era and planned to be disbanded after the Spanish Republic was created in 1931. However the Civil war erupted before, and the latter partly joined the Nationalists, whereas the garrison of Cartagena, and a detachment in Madrid stayed loyal to the new government.

During the cold war, Francisco Franco increased their strength and the Infantería Marina was increased, while in 1957 the Grupo Especial Anfibio was created as a projection force, soon in action at the Ifni war. It as found in action in Spanish Sahara and got new amphibious vehicles, anti-tank weapons, individual equipment and artillery, as well as many ww2-era surplus landing crafts. However there was still no large dedicated assault ship, but from 1960: LCU and LCM were acquired, in 1964 and 1965, Aragon and Andromeda an Haskell-class Attack Transport and attack cargo (Two more in 1980). From 1971, Four ex-US Dock and Tank landing ships.

The Tercio de Armada (TEAR) became the main amphibious unit was restructured through the E-01 Plan. The latter redefined requirements and structures FY2000 for the Spanish Marine Infantry, with rapid deployment capabilities in Central America and Asia as an “emergency force”. It primary role was to evacuate civilians in conflict areas, or to act combined with other allied forces within NATO. In this frame, these were deployed in Afghanistan. Main base today is San Fernando. As in many other countries, special forces (Fuerza de Guerra Naval Especial) were created. They had operated in Somalia, Haiti and Lebanon.

Technical matters

Infanta Elena P-76 Descubierta class

As it appeared, Spain attached a great deal of importance to reach self-sufficiency for ship design and construction. As long as possible, licences were acquired. The process had to advantage to spare a great deal of R&D money and make the finished produced more attractive to the export market. At first, the limited development of local electronics industries and defence industries at large signified the country would purchase most of its hardware abroad. In terms of tanks, apart purchased and upgraded M60 and AMX-30s, only ENASA could provide a truly domestic design, the Pegaso BMR, and later the Pizarro, a join-venture with Austria. In the air, CASA (which started licence-building German planes) provided some decent transport and light aircraft but nothing to the scope of a multirole fighter, although participating in the Typhoon project since the origin.

One example is quite telling about this: The Descubierta class corvettes started with a stretched-out German MEKO design, with German powerplant, Italian and Swedish armament, and Dutch electronics. The Corvettes were quite a success of themselves. More recently anoyher of these example had been the Meroka CIWS using rotating Oerlikon 20 mm barrels and proved quite a potent short-range weapon. Traditionally surface ships and Subs had been built in cartagena, frigates at Ferrol, and small crafts at La Carraca Yard, Cadiz.

Strategy and Operations

Initially the Navy’s main task was to protect what remained of the Spanish colonial empire, but today Spain is not even in the top 20 largest EEZ. The Armada was about also to project traditionally power an prestige, and there had been some actions that mobilized the Armada during the cold war:
-The Ifni war, an enclave attacked by Moroccan irregulars, in five occasions between 1957 and 1965. At some point, the cruisers Canarias, Cerventaes, Nunez with destroyers and supply ships ended in territorial waters of Morocco and in front of the entrance of the port of Agadir.

-There is also the long-standing question of Gibraltar. Standing as a British Bastion since its transfer on 11 April 1713, the “rock” was a point of contention bewteen the two governments since a long time. In 1982 if the British had not sent the fleet and left the Falklands to the Argentines it is likely Spain would have been more willfull to retake Gibraltar by foce if that was not diplomatic skills and the fact the rock was also essentially a large military base, airbase and naval one (and the proximity of Spain to the UK). In 1969-1970 the claims for gibraltar reached boiling point when the freshly acquired aircraft carrier dédalo and escort was sent to the bay of Algeciras, facing Gibraltar. Nevertheless, the carriers Eagle and Hermes had arrived just before and acted as a deterrent.

In the 1980s the whole of the Armada was stationed at Ferrol, to the exception of the Descubierta class in Cartagena. Old FRAM I and submarines were moved to the Mediterranean, but Spain always kept the best and more modern assets in the Atlantic, participating in more and more joint exercises with NATO. Recently the fleet’s doctrine is absed around two scenarios:
-A localized conflict with Islamists taking over nearby Morocco and attacks on Ceuta and Melilla were planned. Threats to the Canarias and fishing fleets were also taken in account.
-A large scale conflict with USSR (or the east after 1990) and according to NATO scenarios, would have cooporeated in the Atlantic for subarine hunting and protect the waters near the Gibraltar strait. In 1987 the main command center was moved to Rota, next to the US naval base.
-In 1990’s gulf war, three Santa Maria class frigates were sent to red sea as part of a multinational policing force.
-In 1994, some Spanish ships under UN mandated participating of a blockade of former Yugoslavia, to stop arms smugglers.

New ships:

In 2018, 138 vessels were in service in the Armada, including small auxiliaries, and comprised amphibious assault ship and transport docks, frigates, submarines, mine warfare vessels, patrol ships and auxiliaries for a grand total displacement of around 220,000 tonnes.

These long-awaited missile destroyers, turned Frigates, were a major milestone in Spanish capabilities. In short, they were the First European Warship With The Aegis Weapon System. This was truly a powerful symbol of the trust and strong military ties wit the US. This class was widely regarded as the most powerful Frigate class in the world at the time. The F100 class were built by Navantia in Ferrol, and in 2018, was naturally selected as one of the five finalists for the U.S. Navy’s FFG(X) program. Their strenght rested around the AN/SPY-1 RADAR, only shared at the time by Japan’s Kongō class, and South Korea’s Sejong the Great class, or more recenntly the Norwegian Fridtjof Nansen class. The design was also the basis for the Australian Hobart-class destroyer.
The Álvaro de Bazán-class incorporated ballistic resistant steel hull, and anti-vibration mounts for the powerplant. They were planned to do the following:
• Medium-size oceanic escort.
• Command and control ship in conflict scenarios, capable of operating with allied fleets, and providing cover to expeditionary forces.
• Capable of operating in coastal and blue waters depending on the conflict situation.
• High anti-air capability.
In addition to the Lookheed-Martin AN/SPY-1, the ship was fitted with:
-Raytheon SPS-67(V)4 surface search radar
-Raytheon DE1160 LF active and passive sonar
-Two ARIES navigation/surface radars
-Two Raytheon SPG-62 Mk99 radar illuminators.
Each of the four vessels (the sixth was cancelled due to budget restraints), were given a powerful armament comprising the following:
-5 in (127.0 mm)/54 Mk45 Mod 2 gun
-CIWS FABA 20mm/120 Meroka system (provision).
-Mark 41 (VLS) (48-cell)
-32 Standard SM-2MR Block IIIA
-64 RIM-162 Evolved Sea Sparrow Missile (4 per cell)
-Eight McDonnell Douglas RGM-84 Harpoon anti-ship missile
-Two twin 12.75 in (323.8 mm) Mark 32 Mod 9 torpedo tubes with 12 Honeywell Mark 46 Mod 5 torpedoes
-Sikorsky SH-60B LAMPS III Seahawk
For active protection they were armed with:
-Four FMC SRBOC Mk36 flare launchers
-SLQ-25A Enhanced Nixie torpedo countermeasures
-Indra SLQ-380 EW suite & Mk 9500 interceptor

LPD Juan carlos

The other major achievement of post-cold war Spanish Naval industry was the LPD Juan carlos, quite a success which conducted Australia to buy the Camberra class based on her in 2008, commissioned in 2014, and the Turkish Navy which ordered the TGC Anadolu with some technology transfer at Sedef Shipyard.

This 26,000 tonnes, 230.82 x 32 x 6.9 m ship was propelled by two 11 MW POD for 21 knots and 9,000 nautical miles range, and carried Four LCM-1E with an overall capacity of 913 soldiers and up to 46 Leopard 2E tanks. Complement of the crew is 261, added to the air wing, 172 strong, this make for a potential 1346 personal on board.

Sensors and processing systems used the LANZA-N air search, ARIES surface search, PAR aircraft landing, EID ICCS integrated communications control system, REGULUS and RIGEL active protection systems, and armament: Four 20 mm guns, two BPDMS and a VLS (FBNW) and four 12.7 mm machine guns with an air group comprising 25 AV-8B Harrier II(or F-35B), with 6 spots for Chinook, Sea King, and NH-90 helicopters. The ideal hangar capacity combination was 11 AV-8B + 12 NH90 + 6 more on the flight deck parking spots.

Spanish Fleet air Arm:


Though the initial 1928 Dédalo (“Daedalus”) was the first Iberian “aircraft carrier”, using Autogyros, the new ship of the same name (R03) in service in 1967 enabled true modern carrier-borne operations to the Armada. The latter carried VTOLs because of size constraints. The choice of a particular plane, the Harrier, was not random: In 1982 the Falkands war pitted Sea Harriers, naval version of the Hawker Siddeley Harrier first flew 28 December 1967 and was introduced with the RAF in 1969. It was a very unique plane on the world stage due to its VSTOL capabilities, offering a relatively small carrier the possibility of using supersonic jets. This served the Royal Navy well, with its medium size WW2 era carriers, and could serve other countries with modest size carriers as well, but also the Unites States: The US Marines found appropriate to have them onboard assault ships as the AV-8 and later the Harrier II.

The navies of Spain and later Thailand bought the Harrier for use as their main carrier-based fixed-wing aircraft. However for Spain this purchase was complicated by long-standing political friction with the British government. Eventually the US Version was purchased, the latter being used as an intermediary, while it was manufactured in the UK. Tests started in November 1972, British pilot John Farley operating onboard the wooden deck of SNS Dédalo. In 1976, the Spanish Navy operated the specifically designed AV-8S Matador. Later later five more were purchased directly from the British government to replace losses in operations. Outside Spain, Australia, Brazil, Switzerland, and Japan were approached but only India purchased the Sea Harrier. Spain later would sold seven single-seat and two twin-seat Harriers to Thailand in 1998 to serve on the HTMS Chakri Naruebet and swapped to the Harrier II.

-13 McDonnell Douglas AV-8B Harrier II (since 1987) + 4 Cessna Citation
-Helicopters: 7 Agusta-Bell AB 212, 5 Hughes 500M, 10 Sikorsky SH-3 Sea King*, 18 Sikorsky SH-60 Seahawk.
In addition, 7 NHI NH90 are on order (2021-22)

Cabot was a USS Independence class light aircraft carrier, launched in April 1943 and completed in July, deactivated in 1947 and mothballed, recommissioned in 27 October 1948 and decommissioned again in 21 January 1955. Decomm. reserve until 1967, loaned to the Spanish Army under MDAP. In 1973 she was purchased outright by the Armada. The USN completely modernized her before transfer. She had strengthened decks and lifts to carry jets, new electronic equipments and modernized electrical network. Two funnels were removed and hangar capacity was established to 20 aircraft, speed 24 knots. In the 1980s the Armada thought to modernize her with US assistance in order to keep her in service with Meroka CIWS and be used in parallel to the Prince de Asturias. She was returned in 1989 to the US and is now on display as a museum ship in New Orleans.

spanish navy Aircraft carrier Principe de Asturias (1982)


This aircraft carrier was approved in 1977 and a tender was proposed for the design (won by Gibbs & Cox), construction was entrusted to Ferrol NyD, and started in October 1979, launched in May 1982 and completed in May 1988. Gibbs & Cox from New York proposed the updated control ship, a type proposed for the US Navy FY 75 but never funded by the Congress, and fitted with a 12 degree ski jump to deliver the planned Harriers, also included in the contract. The final VTOL chosen were the EAV-8B Matador, 17 were to be operated, when delivered from 1987.

The flight deck measured 575 x 95 feets (175.3 x 29 m) with two lifts, right aft and forward of the island, the other offset to starboard. Nominal complement of 17 planes could be in theory pushed to 37 VSTOL aircraft and helicopters. Max operational at once was 24 and Normal operational was 20. Completion was delayed by the installation of a lower bridge and consequent modifications of command and control systems to be used as fleet flagship. In 1990 there was a refit, as the flight control position was enlarged and extended, accommodations increased to 55 more personal. As in the FFG-7 class, two small retractable electric motors in propeller pods provided and emergency steering and propelling solution.

spanish navy Liniers class (Churruca III, 1950)

D-51 Liniers (1951, modernized 1962* BU 1982), D-52 Álava (1951, modernized 1962, BU 1978)

Liniers class

The last of the Churruca serie, largest destroyer class in the Spanish Navy, started in 1924 ended with the “third group” laid down in 1936 but virtually suspended for the duration of the civil war and resumed after design modification at the end of WW2. They were officially laid down again in December 1944 and January 1945, and launched in May 1946 (Liniers) and June 1947 (Alava), completed in January 1951 and December 1950 respectively, so fifteen years after they were first laid down. They had basically the same arrangement of the previous group less the admidhip 120 mm guns, replaced by some AA and two quadruple TTs instead of triple. Also, they received three twin 37 mm, at completion, four more than planned initially, and three single 20 mm AA. Of course this configuration was soon obsolete and by 1961-62 they were taken in hands to be rebuilt and modernized, reclassed as ASW Frigates.

Alava as ASW Frigate

After refit, space was to be found internally and their powerplant was reduced, with an output of 31,500 hp and top speed of 29 knots instead of 36. But they carried now 540 tonnes of oil and had a much better range. The bridge and superstructures were rebuilt, and they were reamed with three 76mm/50 Mk 34, three 40mm/70 SP48 AA, two triple 324 mm ASW TTs, and two 24 tubes Hedgehog Mk 11 ASWRL (178 grenades), eight Depth charges throwers and two racks, about 120 depht charges in store.

The electronics were completely modernized with a new lattice mast to support the radars: MLA-1B and SG-6B radars, Decca TM626 system, two Fire control radars Mk 63 and an American SQS-30A sonar. Alava was stricken in 1978 and Liniers in 1982. Not bad for ships planned in the early 1920s on a WW1 British design.

spanish navy Audaz class (1953)

Audaz, Osado, Meteoro, Furor, Rayo, Ariete, Temerario, Intrépido, Relámpago (BU 1972-82)


These basically were torpedo boats ordered on 30/3/1944, based on the French Le Fier class, dating back from 1936. Drawings were purchased in occupied France in September 1942. Machinery was licenced from Rateau-Bretagne for the turbines and La Seyne for the boilers, all built in Spain under raised steam parameters, as on Oquendo class destroyers and in échelon machinery with alternated boiler rooms and turbines. The construction also massively used welding.

They would largely differ also by their Spanish armament, their 105 mm aft using DP mountings for AA fire. The first batch were armed with these three 105mm/45 SK C/32, two twin 37mm/83 SK C/30, two quadruple 20mm/65 C/38, two triple 533 mm TT banks, four DCT, one DCR, and 30 mines.

They were ultimately laid down in 1945, and delayed because of financial issues and the situation in France in 1945 for some parts delivery, but also SECN. They boilers appeared absolutely unreliable and had to be fixed, causing more delays. Launched in 1951, they were completed in 1953-56 to the original design for the Audaz, Atrivido, Osado and Rayo, but classified as frigates in 1955. They appeared seriously overloaded and had stability problems. The others stayed in for longer, completely redesigned and emerging in 1960-65. In this new version, they were modernized as AS destroyers, and the early four of the first batc were modernized a little later under the same lines. For this second batch, SNS Rayo was the prototype, in 1958. They had US electronics and armament. Ariete was lost in service in the river Mudros. The others were discarded in 1975, Intrepido in 1982.

spanish navy Lepanto class (transf. 1957)

Lepanto, Almirante Ferrándiz, Almirante Valdés, Alcalá Galiano, Jorge Juan


Thes WW2 Fletcher class destroyers were transferred under MDAP from 1957 to 1960 and they were purchased in 1972. They slightly differed in armament, but their modernization consisted in adding ASW torpedo tubes and Hedgehogs and extra AA. They also had a full electronics suite. They were decommissioned in the 1980s, the last, Jorge Juan, in 1988.


Armament: 4 or 5 5-in/38, 2 twin 3in/50 mk33 or 6x 40 mm/60, 6x 20mm, 1×3 533 mm TTs or none, 2×3 320 mm ASWRL Mk.32, 2 Hedgehog, 1 DC Rack.

spanish navy Oquendo class (1963)

Oquendo, Roger de Lauria, Marqués de la Ensenada

Roger de Lauria

These destroyers were initially planned during WW2, based on the French Le Hardi class for which plans were to be provided, planned FY 1943 at first, and ultimately they were heavily modified as the war ended and were ordered in 1947-48, taking in accounts new design trends. They leaned towards USN destroyers design in particular and were to be provided with US armament and electronics. Construction was eventually limited to three ships, the next batch being of the modified design (De lauria class), whereas the next of the first batch, “Blas de Lezo”, “Gelmírez”, “Lángara”, “Bonifaz”, “Recalde”, and “Blasco de Garay” were cancelled in 1953.

Initial armament as planned were to be four twin 4.1 guns, a triple and two twin 21-in torpedo tubes, and two DCT. See the tables for the changes. Oquendo was launched in 1956 and completed in September 1960, her trials showing massive stability problems. Eventually these led to a complete redesign of the other two, initially completion would occur much later in 1969-70. All three were built in Ferrol. Meawnhile before commissioning, Oquendo was partially rebuilt, bay ballasting the hull and reducing top weight, and further modifications made her join active service in 1963. Her initial displacement was 2050/2765 tonnes, 3.6 m draught, 39 knots, three twin 4.7 in/50 DP, six 40 mm/70 AA, 4x 20mm AA, two Hedgehog, two side launching racks for 320 mm ASW torpedoes (no TTs).
After modifications, see the first table.

The Oquendos were, from the start Spanish designers’s worst nightmare. The process took 15 years after material was procured, and at some point assistance was asked from Ateliers de Bretagne in 1955 to complete the power plant, while the boilers had to be remade and modified several times. With such slow progress, it was decided to radically modified the two other sister-ship as their armaments and electronics did not match the reality of the time. They were from Ferrol to Cartagena, cut in half lengthwise to widen them and reduce the stability issue while new weaponry was to be procured as well as new sensors.

Negociation wit the British failed and then the staff turned to the Americans, ultimately to purchase the entire FRAM II system, ande made the De Lauria a clone of the Gearing FRAM. At the end of the process, on paper the new Roger de Lauria and Marqués de la Ensenada seemed well-equipped for their time, but similar mistakes were yest made as on the Oquendo Audaz-class DDs. The original power plant and machinery was kept and despite their state-of-the-art electronic warfare systems and helicopter facilities, plus a modern and well balanced anti-submarine warfare capabilities, which included a variable depth sonar, their operational value was limited while considerable resources had been allocated on this three-ship class which prevented later improvement.

In the end, the three of the Oquendo class had short careers, of 15, 13, and 18 years respectively with average performance in service. In 1981, as Marqués de la Ensenada was to be decommissioned, she was damaged in Santander by a bomb planted by the ETA at the line of flotation buoys. For political reasons, it was then decided to repair it and maintain the ship until 1988, although it was no longer relevant in a modern warfare environement. She was never upgraded with the proposed SAM or Meroka CIWS and was plagued by boilers problems until the end. They were basically Gearing FRAM with less capabilities whereas the originals had been discarded more ten years ago.

spanish navy Baleares class Frigates (1970)

Baleares, Cataluna, Andalucia, Asturias, Extremadura

The Baleares were the largest cold war warships built in Spain when they were laid in Ferrol in 1968, and each year, in 1969, 70, 71 and 72 (two), completed 1973-76. They were superficially clones of the Know clas USN Frigates but in reality were tailored for the Armada and were quite different, in many ways, starting from the absence of raised bulwarks and spray strakes, the “hurrican bow” to more clement waters. Also, the aft section was completely modified, as there was no helicopter onboard, so the quarterdeck instead received the SM-1 standard launcher (Tartar at first). The armament was quite different also, apart the main gun. Instead the Know were given a lighter armament, in addition of the ASROC, the standard SM-1, Harpoon antiship missiles from 1983-91 refit, and more diversified torpedo tubes, of 12.75 inches (323 mm) on the sides angled at 45° and 21-inches (533 mm) in the stern, all fitted internally, plus a more extensive electronics suite. These ships looked liked equivalent to destroyers in firepower whereas the original Knox were pure ASW warfare vessels. The Meroka/CIWS were also aded during the 1990s refit. The Meroka were associated with the RAN 12L FCR.

The Santa María class were six locally built vessels based on the Oliver Hazard Perry-class frigates, in two batches with the second comprising F-85 and 86 received an improved combat-data system and updated SPS-49 and SQR-19 radars and sonars, plus the semi-local Meroka CIWS and Mk92 Mod 6 COR and upgraded electronic warfare suite. The Spanish version of the FG-07 had a slightly broader beam, a Meroka CIWS, RAN-12L air search radar, Nettunel EW suite in place of SLQ-32.

In the late 2010s the ships were modernized with a mid-life update (MLU) comprising a new EW suite and improved combat-data system, upgraded Mk92 FCS and new electrical generators and better habitability, at least for the first batch. The second is planned for 2022-2025.

Small ASW corvettes designed in the late 1940s without clear references, they were one-of-a kind, genuinly Spanish. Atrevida and Decubierta, the first two, were armed as in the tables, but the four otjers were modernized in 1959-60 and displacement was now 997 tonnes standard, 1135 FL, 9 feets or 2.7 m draught, one 3in/50 DP gun, 3x 40mm/70 AA, 2 Hedhehogs and 8 DC mortars plus two racks. They were rated as corvettes but given the prefic F, so some had them registers in frigates, but they were way too small for that. Decribierta and Diana were discarded in 1978 and 1973, the others refitted in 1978 for patrol and fihery protection with the following data:
1031 standard/1118 FL tonnes, 9ft 10in draught (3 m), one 3-in/50 DP, 3x40mm/70 AA, 2×20 mm AA. They were ultimately discarded in 1991-92.

spanish navy Descubierta class Corvettes (1975)

Descubierta, Diana, Infanta Elena, Infanta Cristina, Cazadora, Vencedora

Vencedora F36

Thes ships were developed to replace in the 1980s the Atrevida class. They were larger and better equipped, wth a modern ASW suite, and a composite of technologie from every country. It was truly a “European warship” at a time these collaborations were not yet the norm, but with projects such as the Tornado. The design was prepared by Blohm and Voss shipyards in Germany. They took as model the Joao da Coutinho they developed for portugal, modified by the Bazan yard in Spain before construction, at Ferrol and Cartagena.

In the end, they were ordered in December 1973, with other batches in May 1976 wheras F37 and F38 were sold to Egypt before completion and another built for Morroco. Laid down in 1974-78, they were launched in 1975-79 and completed between 1978 and 1982. The armament was Italian, Swedish and American, electronics were Dutch. They were all in service well past the cold war, and are still in service today.

In the early 1980s was planned a replacement, an improved version of the latter. Several designs were proposed, with a base of 1879 tonnes in displacement, a lenght of approximatively 100m overall, same armament but a hangar and helicopter and gas turbine propulsion for 30+ knots. It was proposed but ultimately declined for the larger FFG-7 model instead.

spanish navy G class submarines (cancelled)

This was the story U-573, a Type VII U-Boat which was in operation in Spanish waters on 1 January 1942, taking refuge after being hunted down by a Sunderland and badly damaged, in Cartagena. She later sold to the Spanish Navy as G-7, entering service in 147 after endless repairs and tests. The 1943 the Spanish naval Programme included six submarines and in 1945 a first batch of four, heavily based on the G7 were ordered, called G1-G4. They were to be based on the Type VII, but plans were ultimaterly abandoned as in the 1950s more modern MDAP provided recent models were to be provided instead.

An honorable mention must go also to the D-class, started in 1934 but delayed at first by the civil war and next by WW2. D1, D2, D3 mixed British design and German equipments, but completion had to wait until 1947 for D1, while D2 and D3 were completed after many modifications as defects were discovered in service, in 1954, so twenty years after they were laid down… Modernization attempts concerned S21 and 22, streamlined S-22 in the 1960s with a new conning tower, modern sonar, radar and sensors. Both were discarded in 1971, later than the training submarine S-11 (former D-1), in 1965. They will be covered more in detail if more is discovered on them later. See also Spanish ww2 submarines.

spanish navy Spanish Midget submarines (1957)

Tiburon class

Foca (S40) class Midget Submarine comprised Foca (SA 41/42) and Tiburon (SA 51/52) were two very different midget submarines, semi-experimental as they were only two of each class. A radical departure over the 930 tonnes (submerged) planned G class, derived from the Type VII, they were experiments. The first serie called Foca I and II (or SA 41 class) displaced 16 tonnes to 20 tonnes submerged, for a hull 13.9 m long, 1.8 m wide and 1.5 m tall. They were propelled by a Pegaso diesel 160 bhp coupled with Siemens electric engines for 110 bhp, and were capable of 9.2/12 knots, armed with two 21-in Torpedoes and having a crew of three. They inspired by the German Seehund class, also for special operations, and were re-rated as assault subs in 1963. Probably discarded in 1971, little info available.

The Tiburon I and II were another pair of prototypes, much larger, faster and powerful with a crew of 5, launched in 1958 in Cartagena. They were re-rated as assault subs in 1965, pennants SA 51 and 52. 78 tonnes/81 tonnes sub., 21.5 x 2.7 x 2.7 m, one shaft with two Pegaso diesels for 4000 bhp and electric motors producting in all 400 shp, for 10/14.5 knots. Both were discarded in 1977.

Peral class Submarines (1971)

In 1971-74, four more submarines of the Balao class, modernized as GUPPY II, were transferred to Spain under MDAP. Pennants were S32-34. S33 Monturiol was laid up for mechanical problems in 1975 and discarded in 1977, the name given to S35 transferred in 1974. So in all Spain operated four GUPPIes in the 1980s. They were discarded in 1982-84. Specs as GUPPY IIA.

They were modernized in the mid-1990s with a towed array Sonar, improved fire control and ECM, new batteries and periscopes. The second class S 80 was a common design by Bazan and Dubigeon (later DCN), ready in 1986 but decision was postponed as it was thought better to used the Scorpene design by DCN instead, postponed in 1999, and modified to the S-80 plus standard, made by Navantia in 2007–2021. They were given French torpedoes L5, F17 et E18 and the Exocet SM39. Modenrized in the early 2000s, one had been retired in 2012, Siroco and one in 2020, Mistral but Galerna (S 71) as well as Tramontana (S 74) are still in service, pending replacement by S-80 class boats.

spanish navy CME class minehunter (1995)

Te replace the old vessels above, Spain considered several designs to be built locally in Ferrol. 12 vessels were considered, either of teh Tripartite or Lerici classes, modern minehunters, pitted against the US MHC design and a local design called “Cazador”. Eventually a contratct was signed in July 1989 with Vosper Thornycroft for Bazan to built a Sandown class derivative under licence with the SRMH GRP materials technology transfer (and later DCN). Eight hunters, four Sweepers. Eventually, order came in 1993, after the cold war, so it goes beyond the present chapter.
