The new submarine of the Spanish Navy made this first outing to the sea in the Bay of Cartagena, for 4 hours and in surface navigation, as reported by Navantia, the construction company. “In the coming months, until the delivery to the Navy in 2023, the Navantia shipyard in Cartagena will continue to carry out the various port and sea tests planned in the calendar, including a grounding of the submarine during the summer months.”

The director of the Submarine Business and S-80 Program, Germán Romero Valiente, has pointed out: “The submarine is a system of systems and it is essential to check the correct operation of all of them and their integration. This first navigation has confirmed the excellent level of integration and performance. For all of us who work on this project, verifying the achievement of the different milestones is a source of pride and an incentive to continue advancing in this technological challenge.”

Romero pointed out that this first exit to the sea is one of the most important milestones within this program, “which represents a technological leap for both the Navy and Navantia. Navantia has highlighted that with this project, Spain is part of the small group of countries that have the capacity to design, build and maintain submarines.

Navantia has published two videos of that first exit to the sea of the “Isaac Peral”:

The “Isaac Peral” has a length of 80.81 meters, a beam of 11.68 meters and a depth of 13.69 meters, with a diameter of 7.3 meters and a surface displacement of 2,695 tons. She is scheduled to reach a speed of 19 knots on the surface with a range of 50 days. She will carry six torpedo tubes, and her delivery to the Spanish Navy is scheduled for February 2023.

The “Isaac Peral” will be the first of four submarines of her class. The second will be the “Narciso Monturiol” S-82 and its delivery to the Navy is scheduled for December 2024. The third, the “Cosme García” S-83, will be delivered in October 2026, and the fourth, the “Mateo García de los Reyes” S-84, in February 2028. Currently, the Spanish Navy only has two active submarines: the “Galerna” S-71 (launched in 1981) and the “Tramontana” S-74 (launched in 1984).
