Leonardo da Vinci's fighting vehicle is one of the conceptions of the revered Italian polymath and artist Leonardo da Vinci.[1]


The machine was designed while Leonardo da Vinci was under the patronage of Ludovico Sforza in 1487.[2] Sometimes described as a prototype of modern tanks, Leonardo's armoured vehicle represented a conical cover inspired by a turtle's shell. The covering was to be made of wood and reinforced with metal plates that add to the thickness. Slanting angles would deflect enemy fire. The machine was powered by two large inside cranks operated by four strong men. The vehicle was equipped with an array of light cannons, placed around the perimeter.[3]

The gears of the design were located in a reversed order, making the vehicle unworkable. This is thought by some sources to have been a deliberate mistake by Leonardo as a form of security, in case his design was stolen and used irresponsibly.[4]

The armoured vehicle was designed to intimidate the enemy rather than to be used as a serious military weapon. Due to the vehicle's impressive size, it would not be capable of moving on rugged terrain. The project could hardly be applied and realized in the 15th century.[5]

Around 2010, a group of engineers recreated Leonardo's vehicle, based on the original design, and fixed the mistake in gearing.[2]

The video game TABS depicts the machine as the boss of the Renassance faction, called the Da Vinci Tank. The tank is also playable in Assassins Creed: Brotherhood, which is set in the time of Leonardo.
