​​​​​​​ASSIGNMENTS

The reduced acoustic, electromagnetic and thermal signature makes it one of the stealthiest conventional submarines in the world, impossible to detect without resorting to a high number of surface assets equipped with the latest sensors, manned by highly trained operators and in favorable weather conditions. Since its commissioning on the 17th of June of 2010, it has performed several maritime area surveillance missions of national interest and participated in several national, international and NATO exercises. The 1st Atlantic crossing to the USA of a Portuguese submarine is also noteworthy.​​
