In an age where nuclear, biological, and chemical warheads are primarily delivered by submarines, anti-sub roles are numerous and highly developed. These robots are too small to detect with any passive systems on submarines, and can silently approach the nuclear leviathans to drill explosive charges into the hull. Modified sub-hunters have even been used by asian and south american pirates to board and assault tankers and merchant ships.

Key Features-
-Large central propellar and jets are the primary mode of conveyance.
-Limbs bunch up to body during
nautical travel to reduce drag.
-High explosive projected charge with a drill head used for breaching hulls and causing irreparable damage.
-Powerful, supra-heated talons for anchoring to hulls, and tearing open bulkheads and bulwarks.
-Variable vents for steering and speed adjustments.
