The S-82 “Narciso Monturiol” submarine, the second of the S-80 class, is now afloat in Navantia's shipyard in Cartagena as it prepares for the final stages of its construction and commissioning, including harbour and sea trials.

The submarine sits in the water after a long an delicate manoeuvre, carried out over several hours using a floating dock and involving a series of essential tasks and checks to ensure the operation was conducted safely, both inside and outside the submarine.

From now on, harbour trials will verify all systems, with key safety milestones such as fuel loading, battery charging, and propulsion tests while moored. Once these trials are completed, sea trials (including navigation and diving tests) will begin, paving the way for delivery to the Spanish Navy.

The S-80 programme will provide the Spanish Navy with four state-of-the-art conventional (non-nuclear) submarines and establishes Navantia as the Technical Design Authority.
