Following the losses Fahrong took in the Maecenas due to Rahmos Steel Legion Engines, the Confederation needed a powerful mass-producible engine of their own. Superficially similar to Rahmos engines, the Ontos is a unique vehicle in its own right. Curvier than its northern counterpart, the vehicle is significantly more elegant, hiding its devastating power. Superior Fahrong armor makes the Ontos a very difficult target to destroy from any angle. The main firepower, a 95mm high velocity cannon in a large turret with a heavily armored mantlet and integrated stereoscopic rangefinders gives it more efficient killing power than the veritable land battleships that the Rahmos engines represent.  All variants have a front-mounted 11mm machine gun, and most have a second and third on the left and right sides in armored casemates. Two Coreburner boilers power the steam drive train, giving the tracked vehicle a surprisingly high speed for its weight, with vibrations being the limiting factor in the vehicle’s speed, as opposed to engine power. While relatively untested in combat, the Ontos is, on paper, possibly the best engine in the world.

Variants
Hellfire – The Hellfire Ontos is the newest variant of the engine, replacing the turret with a semi-fixed rocket launching system. Capable of launching 175mm spin-stabilized rockets of varying type, the Hellfire can fulfill many artillery support roles, capable of firing accurately at large targets, or spreading a rain of rockets over a large area to suppress exposed enemy forces. Once a volley is fired, reloading is a lengthy process and the Hellfire is vulnerable when faced with close combat situations with enemy engines.
Troop Carrier – In order to provide better armored protection and greater capacity to its troop moving ability, the Ontos design was easily modified to carry a squad of Confederate soldiers. The side machine guns are replaced with armored doors and the large main turret is replaced with a small one armed with a chain-fed 20mm cannon.
