"Navantia believes the Armada Espanola's next-generation S-80A design will establish its credentials as a submarine prime contractor and systems integrator. Weapons already earmarked for the S-80A submarine comprise the Atlas Elektrinik DM2A4 electrically powered heavyweight wire-guided torpedo; the Boeing Sub-Harpoon anti-ship missile; and the SAES Mincoa multi-influence mine. The propulsion plant developed for the S-80A is a hybrid arrangement of classic diesel-electric (combining three 1,200 kW-rated Navantia MTU 16 V 396 SE 84L-GB31l diesel alternator rectifier sets and two 180-cell groups of Tudor batteries) and a 300kW AIP system based on reformed ethanol and liquid oxygen."
