The Modèle-4FV is the latest creation of Demain Co. Designed through the years of 1858-1861, It is designed to be a Mobile Hot Air Balloon. It is planned to be produced in Georgia this year to aid in Recon and Supply Movement, as the Vehicle can also be used to move heavy weapons such as Mortars, Cannons, or the future invention of "Gatling Guns". It runs on improved technology from British Traction Engines; its hull is reinforced with metal sheets to protect against Normal Rifle fire, including having a Reinforced Boiler Tank. It is awaiting production and approval.
