The S-61 Delfin was retired from the active service among the Army ships on December, 10th, 2003, after 29 years of uninterrupted service at sea. The Ministry of Defence - in the person of the then minister Federico Trillo - and the Torrevieja council signed on the 4th of February, 2004, the agreement to hand over the S-61 Delfín . That was the first time that the Spanish Army handed over one of its ships to a Spanish council. In this way, Torrevieja has become the first municipality in having an Army submarine. Converted for use as a 'living museum', the S-61 Delfin , a permanent static exhibition and a first-rate tourist and cultural attraction for the city, is situated in the Torrevieja fishing wharf dock.
