CARTAGENA, Spain -- Navantia has launched the second Isaac Peral (S-80) class submarine, Narciso Monturiol, for the Spanish Navy at its facility in Cartagena. With the submarine now in the water, the manufacturer will begin conducting harbor trials, testing the power, propulsion, and other onboard systems. Following harbor tests, the submarine will begin sea trials, assessing capabilities such as seaworthiness, diving, weapons, and sensors.
Spain's Isaac Peral submarines are an incoming class of air-independent propulsion (AIP) diesel-electric boats under construction since 2007. The lead boat, Isaac Peral, was commissioned on Nov. 30, 2023. The newly launched Narciso Monturiol is expected to enter service in 2026, followed by the Cosme Garcia in 2028, and the Mateo Garcia de los Reyes in 2029. The Spanish Navy is considering plans to order an additional two boats in the future.
