Successful Power up of the Spanish Navy S-81 Submarine: One Step Closer to Delivery

The power-up is carried out in order to check the sub’s correct operation, both individually and integrated along with the rest of its equipment

  Navantia has successfully carried out the power-up activity tests to the S-81 “Isaac Peral” submarine. The S-81 is the first of four S-80P class submarines under construction for the Spanish Navy by Navantia. The Power-up is a very relevant safety-related commissioning milestone prior launching, scheduled for the spring of 2021.The power-up is the very first time in which the boat is electrically energised. This involves the start-up of the main electricity distribution networks as well as the emergency systems, which allow the gradual electrification of the entire submarine’s equipment. The power-up is carried out in order to check the sub’s correct operation, both individually and integrated along with the rest of its equipment.

The S-80P submarines are 3,000 tonne non-nuclear submarines provided with a revolutionary third generation Air Independent Propulsion (AIP) system, powerful attack capabilities including heavy weight torpedoes, mines and submarine launched anti-ship and cruise missiles, etc. This is quite an exceptional performance; in fact the capacity to launch submarine cruise missiles (SLCM) is unique for non-nuclear NATO submarines.

The main innovation in Navantia S-80P submarine is the last-generation AIP system, developed by the company in cooperation with Abengoa and Collins Aerospace, named Bio-Ethanol Stealth Technologies (BEST). This system enables up to three weeks underwater operation with low-consumption profiles. The combination of such AIP system together with next-generation Lithium-Ion Battery (LIB) systems is complementary since LIB systems are ideal for full speed scenarios facilitating quick entering or exit from warfare scenarios. Long underwater patrol periods combined with high speed possibilities bring tactical capabilities to a new level.

The S-80P submarines are proposed as baseline for the P75 (I) project, the most important and strategically significant naval programme being undertaken by the Indian Ministry of Defence (MoD). Taking into account the advanced stage of construction of these submarines in Spain, and the fact that the Indian Navy requirements are very similar, the S80P appears as the lower risk solution.

Navantia is fully committed with the Make in India philosophy having gone itself through a similar experience over the last decades, evolving from fabricator only using foreign designs to a turnkey supplier able to go through all design, build, commission and life cycle support phases, positioning the company to assist other navies and international shipbuilders with a wide range of Transfer of Technology (ToT) solutions.

Long term relationship

Navantia is present in India for 15 years now. The company participated in the design and transfer of technology to India’s six Scorpene submarines being built in Mazagon Dock Shipbuilders Ltd, Mumbai (formerly Mazagon Dock Ltd or MDL) deploying a resident team in India between 2006 and 2013. Besides, it is currently taking part in the Landing Platform/ Dock (LPDs) tender teaming with Larsen & Toubro Defence and counts on a full support from the Spanish Navy as the visit of the LHD Juan Carlos I to Mumbai in 2017 proves.

For P75(I) project, Navantia is willing to provide the required “Know How” and “Know Why” through a Technology Transfer programme to achieve permanent design, construction and maintenance capabilities in India.

Navantia wishes all ranks of Indian Navy and their families a very Happy Indian Navy Day
