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 Isaac Peral class submarine can be armed with the DM2A4 heavy torpedo SeaHake, the UGM-84 anti-ship missile Sub-Harpoon, and SAES mines.

The S-80's air-independent propulsion (AIP) system is based on a bioethanol-processor consisting of a reaction chamber and several intermediate Coprox reactors. Provided by Hynergreen from Abengoa, the system transforms the bioethanol (BioEtOH) into high purity hydrogen. The output feeds a series of fuel cells from UTC Power Company.
