Before the A7V was even complete a much larger tank was planned. Requirements for the K-Wagen were that it was supposed to have 4 cannons (or 2 cannons and two flame throwers), several machine guns, and be able to cross trenches 13 feet (4 meters) wide. It was origianally sopposed to weigh 100 tons! And be powered by two 200 horsepower engines. The vehicle was soon considered to be impractical for non-positional warfare, however two prototypes were almost completed before the end of the War. By the time the two prototypes were completed they weighed 150 tons! and were to be manned by 27 people! 7 Maxim machine guns were to provide protection, one facing forward on each sponson, one facing backwards on each sponson, one on each side of the hull ahead of the sponsons, and one at the front of the hull. At the end of the war the almost complete vehicles were examined by the allies then scrapped. The K-Wagen was the largest, in physical dimentions, ever built; at 43 feet long, 20 feet wide, and 10 feet tall. It was also the second heaviest tank ever built; second only to the Maus.
