A ship powered by spirit. advancement of the Spanish Orca

Recently, I went to southeastern Spain at the invitation of Navantia, part of the state industrial group SEPI (Sociedad Estatal de Participaciones Industriales). In Carthagen shipyards in the autonomous community of Murcia are built submarines of the S-80 Plus task for the Spanish Navy (Armada Española). In the course of my visit, I came to learn about the training tools utilized by the submariners preparing to service on the units built there. For the sake of full transparency, I would like to stress that the costs of transport and residence were borne by the hosts.
