Kraken Class Submarine

Half submarine and half battleship, the silent but deadly Kraken class fires it's specialised railguns and huge torpedo banks from deep beneath enemy units where (fully shielded) it sails at up to 19m/s making it extremely hard to hit despite it's enormous size. Designed with positive bouyancy the sub should slow down and surface when out of a fight. During a fight will attempt to track 100m above the seafloor.
