The RS-1050. This design was originally created by the European Coalition as a research platform to both imitate, and study Molochs up close, all while in a protective shell.
This submarine, however, had been captured by the Jovian Separatists and has been retrofitted with hardpoints and modified to act as a small attack vehicle. With the guise of Moloch acting as a fear factor it can be effective to decrease morale, or by chance too misidentify and subsequently, prepare an inadequate defence against.
Boasting three small Coilguns each with their own supercapacitor, positioned on the underside of the submarine, it can quickly destroy enemies of both flesh and steel.
With a large hardpoint atop the submarine, it can easily defend against larger threats, usually attacking from above due to the seemingly constant sinking whilst in the Europan oceans.
