The submarine S-82 “Narciso Monturiol”, the second vessel in the S-80 series, has reached a new milestone in its development by starting its diesel engines for the first time at the shipyard in Cartagena, Spain.
The progress was announced on Friday 20 March 2026 and represents an important step in the so-called harbor tests, a series of tests that are carried out before the sea trial phase.
According to the published information, this procedure brings the submarine closer to its future delivery to the Spanish Navy, which is expected to commission the vessel as part of its program of renewal and modernization of the submarine fleet.
S-82 «Narciso Monturiol» is part of S-80-class, developed to expand the Spanish Navy’s operational capabilities with platforms that offer greater autonomy, stealth capabilities and technological capability.
The first activation of the diesel engines is considered an important moment in the vessel’s schedule, as it confirms progress in the integration of essential systems and prepares the submarine for the next phases of technical tests.
The S-80 program is one of the strategic projects of the Spanish maritime defense industry, and every new advance in the development of these vessels is closely followed by both the military sector and the country’s industrial base.
