“We Would be Glad to Cooperate with Türkiye in the MILDEN Program as We Have Done in Surface Ships!”

The S-81 Submarine ‘Isaac Peral`, the first Spanish-designed and built submarine, was launched in May 2021, conducted the initial sea trials and its first navigation in the Bay of Cartagena in May 2022, performed its first static dive in March 2023 and commissioned on November 30, 2023. Since then, the S-81 Isaac Peral, the first submarine designed in Spain and the first of four boats on order under the S-80 Program, has been operated by the Submarine Flotilla at the Cartagena Arsenal.
