The Isaac Peral class , known as the S-80A class , is a submarine class under construction in the Spanish Navy , designed by the Spanish defense company Navantia . With the exception of boats 1 and 2, it has a diesel-electric drive as well as an external air-independent drive based on fuel cells .
development
The first plans for a new submarine class, which were to replace the S-60 and S-70 class boats manufactured under French license in Spain in the long term , began in 1988. At the beginning, the plan was to cooperate with one foreign shipyard with experience in submarine construction. From a close cooperation between the Spanish state shipyard IZAR (now Navantia ) and the French DCN finally went scorpène-class submarine out, but this was ultimately obtained from either of the two nations and thus became a pure export model. In 1997, the Spanish Ministry of Defense decided on a largely national redevelopment, and in 2001 the requirements for the class were specified, including an external air-independent drive and the possibility of attacking land targets from a greater distance. In March 2004, four boats were ordered; a second construction lot originally planned, consisting of two to four additional units, is no longer planned.
Due to the complex propulsion system and later also due to budget problems, the completion of the boats is delayed. While the original plans were based on the commissioning of the S-81 in 2011, the Armada did not expect the first boat to be delivered until March 2015. The simulation system manufactured by Indra Sistemas was delivered to the military arsenal in Cartagena in October 2011 .
In May 2013, after a review of the design, which took place shortly before the planned launch of the type ship, the Navy and Navantia issued an additional 1 to 2 due to a design error that resulted in an excess weight of around 100 t and associated problems with buoyancy -year delay known. The so-called "Critical Design Review" of the changes, including an extension from 71 to 80 m, was approved by the client in July 2016.
The program was delayed again, so that the first boat will be put into service in 2022, 10 years after the original date.
technology
drive
In addition to a diesel-electric drive, consisting of three MTU 16V 396 SE 84L diesel generators and lead-acid batteries (Tudor / Exide ) manufactured by Navantia under license , the S-80 class, due to various problems, is only available from boat no. 3, also via an air-independent propulsion system (AIP) that allows the boats to be operated for up to 44 days without a snorkel at a speed of around four knots. This is developed by Hynergreen , a subsidiary of Abengoa , and is based on polymer electrolyte fuel cells that are supplied with hydrogen via a bioethanol reformer . The carbon dioxide produced during this process is discharged into the seawater using a system developed by Bionet Ingeniería . The boat is powered by a 3,500 kW permanent magnet excitation synchronous motor from Cantarey (a subsidiary of the Gamesa Group ).
Armament
The S-80A-class submarines have six 533 mm ejection torpedo tubes . The torpedoes are not started in the tube here, but ejected from the tube with pressurized water and only start up a short time later in order to prevent the boat from being located when it is launched. In addition to DM2A4 hake torpedoes, anti-ship missiles of the UGM-84 Sub-Harpoon Block II type can also be fired through the tubes . A total of up to 18 torpedoes or missiles can be carried, or alternatively up to 36 sea mines . The originally planned integration of the cruise missile UGM-109 Tomahawk was canceled in 2009 for budget reasons.
electronics
The S-80A-Class has a sonar set developed by Lockheed Martin consisting of cylinder sonar at the bow, flank sonar, passive ranging sonar, interception sonar for enemy sonar signals and active high-frequency sonar. The Spanish company SA de Electrónica Submarina (SAES) produces an inherent noise control system and the towing sonar . Attack and surveillance periscopes from Kollmorgen Electro-Optical / Calzoni are available as optical sensors . An ARIES-S LPI radar from Indra Sistemas provides navigation when the surface has surfaced .
The command and weapon deployment system was developed by Lockheed Martin in collaboration with Navantia FABA and is essentially based on that of the Virginia class . The control of the application system is done by twelve of Sainsel produced CONAM SUB consoles.
Mission profile
In addition to the classic deployment profiles of a hunting submarine, mainly fighting surface and underwater ships and reconnaissance, the boats of the S-80 class are also designed for tactical attacks on land targets and to support amphibious operations near the coast. In addition, a special unit of up to eight men, such as combat swimmers, can be carried along, who can exit and re-enter the boat for covert operations via a pressure lock.
units
The four units are named after the Spanish submarine pioneers Isaac Peral , Narciso Monturiol and Cosme García as well as after the commander of the first submarine flotilla of the Armada Mateo García de los Reyes .

export
Since the Spanish Navy ultimately only decided to buy four instead of the originally planned up to eight units, Navantia is striving to place the boats on the export market. Since most of the competing products on the market, mainly AIP hunting submarines such as the submarine class 214 , the Scorpène class or the Swedish A26 class , are usually smaller and not designed for attacks on land targets, if you think your chances are good. Only the Japanese Sōryū class is similar to the Spanish design, but is not offered internationally. Initially, the Royal Australian Navy and the Norwegian , Indian and Thai navies had expressed interest in the S-80A class. Ultimately, however, everyone who was interested decided on a different type of model.
