Spanish submarine to go undetected longer with world-first propulsion system
SMRTR summary
The Spanish Navy's S-80 class submarines are receiving an innovative air-independent propulsion (AIP) system from Navantia. This technology generates electricity from bioethanol and oxygen, allowing submarines to stay submerged 2-3 times longer than conventional vessels. The Cosme Garcia (S-83) is the first to receive this upgrade, which reduces detection risk by minimizing surfacing needs. As the only 3,000-ton submarines with AIP capability, the S-80 class are among the most advanced conventional submarines available.
