S-80 Plus-class submarine
The S-80 Plus class (or Isaac Peral class) is a Spanish class of four submarines being built by the state-owned Spanish company Navantia at its Cartagena shipyard for the Spanish Navy. In common with other contemporary submarines, they feature air-independent propulsion.

The class has its roots in the late 1990s, and Spain ordered the submarines into production in 2003. Due to problems with the design, it had to be extensively redesigned in the 2010s, and a Spanish government budget crisis forced additional delays. The submarines are as of 2023 slated to begin entering service in the same year. On November 30, 2023, the first submarine of the class entered service with the Spanish Navy
They are oceanic submarines of medium tonnage with the capacity to carry out long duration missions in scenarios far from their base, acting with a minimum level of indiscretion. They will have an integrated platform control system that allows operation with a reduced endowment and a high degree of automation with remote control. The characteristics of this class of ships place them at a level close to those of nuclear propulsion.
The lead boat in the class, the Isaac Peral, the first unit in the series, was launched by King Felipe VI and his daughter, Princess Leonor, heir to the throne, on 22 April 2021 at the Cartagena shipyards, entered to service in 2023, after originally being targeted for 2011. The remaining three boats are slated to be delivered in 2024, 2026 and 2028. The S-80 class has also been offered for export.
