The S-82 “Narciso Monturiol” submarine, the second unit of the S-80 series, reached a new milestone in its development by starting its diesel engines for the first time at the Cartagena shipyard in Spain.
The progress was announced this Friday, March 20, 2026, and represents another important step within the so-called harbor trials, a set of tests carried out before the sea trials phase.
According to the information released, the procedure brings the submarine closer to its future delivery to the Spanish Navy, which is expected to incorporate the vessel as part of its submarine fleet renewal and modernization program.
The S-82 “Narciso Monturiol” is part of the S-80 class, developed to expand the operational capabilities of the Spanish Navy with platforms offering greater autonomy, stealth, and technological capability.
The initial activation of the diesel engines is considered a significant 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 testing.
The S-80 program is one of the strategic projects of Spain’s naval defense industry, and each new milestone in the development of these vessels is closely followed by both the military sector and the country’s industrial base.
