In a statement, the Navy explains that "this training, together with national and international entities, allows the testing of the latest technologies and unmanned vehicles, essential for defence and security at sea".


The same information note states that "the mission of the frigate Bartolomeu Dias is based on testing and perfecting tactics against threats such as those that have been used in current conflicts".

Two Black Shark torpedoes were also fired from the NRP Arpão, "with the aim of ensuring the response capacity and effectiveness of the subsurface naval reaction".
