All T1 Submarines feature the standard torpedoes for their faction. All Four factions have one and all four have their perks and advantages. All four fire salvos of torpedoes every four seconds, for a total of 150 damage. Three of the four have a deck gun for use while surfaced (the exception being the Aeon Sylph) which can outrange any other t1 surface weapon, though weaker than the cannons of frigates.
