The Kostroma is a cheap submarine type mass-fabricated by the Coalition for assault and interception purposes. Hated by crews for its cramped interior and troublesome externally-mounted engines, the submarine's only saving grace is its high speed and the fearsome modified chaingun mounted under its nose. Submarines in this type are often sent to war in pods of three to five vessels.

This vessel is heavily inspired by rundoomer's Apollo Project submarines, I highly recommend checking them out.
