Navantia Presents S80 Plus Submarine at UDS 2020

Navantia participated in the “Underwater Defense & Security 2020” conference, organized by Defense Leaders from 3 to 5 March in Southampton in London.

The Engineering Director of the Cartagena Shipyard, Germán Romero Valiente, made a presentation of the characteristics and capabilities of the S80 plus submarine, which make it a unique product on the market due to its size and capacity thanks to the AIP (Air Independent Propulsion) system.

This edition of UDS had a record participation of attendees and speakers from 36 countries, who had the opportunity to be informed about the progress of our S80 plus program, from the point of view of its construction and its robust design that makes it suitable for export.

Currently, the first submarine in the series, the S-81 Isaac Peral, has passed the hull closure milestone and is in the Submarine Armaments Ship (NAS). The launch is scheduled for the end of this year 2020, its tests during 2021 and delivery to the Spanish Navy in 2022.

The anaerobic propulsion system (AIP system) has been developed, specifically for the project, by the Spanish company Abengoa and the American company Collins Aerospace (the former was in charge of the bio-ethanol reformer and the latter, of the fuel cell).

The AIP system is much more versatile and effective than others on the market and includes as advantages: it uses internationally available agricultural bioethanol fuel, fuel cell membranes require half the maintenance of the market standard and its efficiency allows it to operate for periods of up to 3 weeks underwater.

The S-80 plus submarine is a highly technological product of the latest generation, whose versatility allows export. Navantia is currently offering a design derived from the S-80 plus to the Indian Navy for the P75 (I) project, which includes the design and construction of 6 units.
