Navantia Pitching S80 Plus during Underwater Defence & Security 2020 conference
It is scheduled to be floated at the end of this year 2020, tested during 2021, and delivered to the Spanish Navy in 2022
Navantia has participated in the "Underwater Defence & Security 2020" Conference, organized by Defence Leaders, that took place in Southampton, in London from 3-5 March. The Cartagena shipyard Engineering Director, Germán Romero Valiente, made a presentation of the characteristics and capacities of the Spanish S80 Plus submarine, which is a unique product in the international market for its size and capacity, thanks to its AIP system. As well, Navantia was also invited to a panel of experts where future trends in rescue and underwater rescue were discussed.
This edition of UDS has had a record participation with attendees and lecturers from 36 countries, and in this occasion Navantia has been able to report on progress of the S80 Plus submarine program, both from the constructive point of view, as of a robust design that makes it suitable for export.
Currently, the first submarine in the series has passed the hull closure milestone and is scheduled to be floated at the end of this year 2020, tested during 2021, and delivered to the Spanish Navy in 2022. The AIP (Air Independant Propulsion) system has been developed specifically for the project by the Spanish company Abengoa (bioethanol reformer) and the American Collins Aerospace (fuel cells). The AIP system is much more versatile and efficient than others on the market. Among other advantages, it uses an agricultural bio-ethanol, available internationally, 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 last generation highly technological product, whose versatility allows the export. Currently Navantia is offering a design derived from this submarine to the Indian Navy, for the P75(I) program, for design and construction of 6 units.
