With the S-80 program, Spain becomes one of the few countries that can design and build submarines, an extremely complex task because these vessels must operate autonomously in a hostile environment. Therefore, they require highly specialized skills in different areas of knowledge and a highly qualified industrial and technological industry.

The S-80 also called Isaac Peral-class is Spanish-made submarines in production by the Spanish company Navantia in its Cartagena shipyard for the Spanish Navy. The next phases will be harbor tests and sea tests, which include sailing up to the maximum operating depth. The first sailing is scheduled for early 2022 and will be delivered to the Navy in early 2023.

The submarines will have an overall length of 80.8 m, a diameter of 7.3 m, and a submerged displacement of around 3,000 tones. They include the integrated combat system and platform control system developed by Navantia Sistemas the integrated platform control system developed by Navantia Sistemas. They will have BEST-AIP, an atmosphere-independent propulsion system, which supplies the ship with electrical power at any depth so that it can remain underwater for longer periods.

The S-80 has improved considerably its stealth capabilities, the main attribute of a submarine. The S-80 stands as the world’s most advanced conventional submarines and has drawn the attention of several navies and opened opportunities in a highly technological international market.

The S-80 is powered by Air-independent propulsion (AIP) allowing a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel). The propulsion system includes three diesel engines rated at 1,200 kW each, a 3,500 kW main electric engine, and a 300 kW air-independent propulsion (AIP) reactor. The submarine will be able to reach a surfaced speed of 12 knots (22 km/h) and 19 knots (35 km/h) in submerged conditions. The S-80 has a crew of 32 sailors.

The S-80 is armed with 6 × 533 mm torpedo tubes and will carry six torpedo launchers and 18 weapons, including mines, DM2 A4 torpedoes, MK48 torpedoes, Harpoon anti-ship missiles, and Tomahawk long-range cruise missiles.
