Navantia Passes the First Safety Milestone of the S-81 Submarine: The Power-up
NAVANTIA SHIPYARD IN CARTAGENA has successfully carried out the power-up activity tests to the S-81 “Isaac Peral” submarine. The S-81 is the first of four S-80P class submarines under construction for the Spanish Navy by Navantia. This is a relevant safety-related commissioning milestone prior to delivery. The power-up is the very first time in which the boat is electrically energised. This involves the start-up of the main electricity distribution networks, as well as the emergency systems, which allow the gradual electrification of all the submarine’s equipment. The power-up is carried out in order to check the submarine’s correct operation, both individually and integrated along with the rest of its equipment.
The S-80P submarines are 3,000 tonne non-nuclear submarines provided with a revolutionary third generation Air Independent propulsion (AIP) system, powerful attack capabilities including heavy weight torpedoes, mines and submarine launched anti-ship and cruise missiles, etc. This is quite an exceptional performance, in fact, the capacity to launch submarine cruise missiles (SLCM) is unique for non-nuclear NATO submarines. The S80P submarines are proposed as baseline for the P75(I) project for India. The S-81 shall be launched during the spring of 2021, as planned.
