We have mentioned it in recent days: the renewal of French attack submarines is well underway. On the one hand, the Suffren, the first in a new class of nuclear attack submarines, now floats freely and is currently starting its sea trials. On the other hand, the French Navy received its first new generation heavy torpedoes, which will constitute the main armament of these new buildings.
