While the first manned explorations of Europa's deep oceans were armed, these meager defenses proved horribly insufficient for the hostile nature of local megafauna. Earth crash designed military submarines, with the Humpback and Warspite classes being the most prolific. Primitive in design compared to modern powerhouses, the rare remaining Warspite carries immense frontal firepower and luxurious internal fittings at the cost of a obsolete, fuel hungry power network and limited automation.
Tier 2 Attack Class submarine themed around world war era battleships. Vanilla styled as a larger partner to the Humpback. Notably includes superfiring main battery, security camera, and upper transit deck.
