Barracuda
Though the number of built submarines was limited, some of Barracudas are still in service. In the battle they suddenly burst forth from the water, annihilate enemy ships and change the tide of the fight to the victory.
Seagull
The absence of armor is fully compensated for by high mobility, proved reliability and low mass, considering that at the time of its deployment the enemy had no anti-aircraft artillery.
Stingray
Stingrays are good in every aspect, except for amount of resources required to build and maintain them. Due to this reason, they are gradually phased out of service and rarely take part in combats.
Mantaray
The Mantarays, incredibly costly yet enormously destructive flying death machines, are extremely rare to be seen in a battle.
