The S-80 Plus class (or Isaac Peral class) is a Spanish class of four submarines—late-1990s design, initial production order in 2003, redesign/rebuild mid-2010s, and currently in production—being built by the state-owned Spanish company Navantia in its Cartagena shipyard for the Spanish Navy.

The S-80 Plus-class submarines have a full load displacement of 3,200 tons, a total length of 81.05 m, a beam of 11.68 m, and a draught of 6.20 m. The submarine has a crew of 32 personnel and can accommodate eight troops. The S-80 is able to reach a top speed of 12 knots (22 km/h) on the surface and 19 knots (35 km/h) when submerged.

The submarine is powered by three bio-ethanol engines, one 3,500kW main electric engine, and a 300kW air-independent propulsion (AIP) reactor.

The Integrated Combat System Core (ICSC) is called VC 9.0 SCA. The ICSC provides a set of weapons and sensors of the combat system with optimal management of the command and control center, allowing to acquire, evaluate and present all the necessary information for the offensive, defensive, or intelligence gathering actions at each moment.

The ship is fitted with active and passive sonars with accurate electromagnetic detection systems. The submarine can communicate via Link-11 and Link-22 data links.

The Isaac Peral class submarine can be armed with DM2A4 heavy torpedo SeaHake, Harpoon missiles UGM-84 Sub-Harpoon block II, and UGM-109 Tomahawk.
