The “power up” consists of activating the submarine’s main and emergency electrical distribution networks. This process enables the safe supply of power to onboard systems, allowing for further tests and operational preparations.
This milestone is part of the Safety Milestones Management Plan, which ensures that construction and testing are carried out with the lowest possible risk level. The structured approach is designed to support the safe and efficient progress of the S-80 programme.
In addition to the safety milestone, the first Harbour Acceptance Tests for the Narciso Monturiol have been completed. These tests form part of an extensive evaluation programme, which includes more than 1,500 verifications covering acceptance and builder trials.
The progress of these tests aligns with the overall timeline of the S-80 programme. The first submarine in the series is already in service with the Spanish Navy, while the second vessel is undergoing trials before its planned launch next summer.
The S-80 submarines are conventionally powered vessels with a length of 80.8 metres and a submerged displacement of approximately 3,000 tonnes. They incorporate a combat and platform control system developed by Navantia Sistemas and an anaerobic propulsion system known as BEST-AIP.
The BEST-AIP system is designed to generate electrical energy from fuel cells at any depth, enabling the submarine to remain submerged for extended periods without surfacing. This enhances its operational autonomy and discretion.
Navantia has noted interest in the S-80 submarines from several international navies, including those of Poland, the Philippines, and Canada. The programme represents a step forward in submarine technology, positioning Spain as a contributor to developments in the sector.
The S-82 Narciso Monturiol will continue undergoing testing and verification as it progresses toward its scheduled launch.
