A landship is a large vehicle that travels exclusively on land. Its name is meant to distinguish it from vehicles that travel through other mediums such as conventional ships, airships, and spaceships. Military committees Landship Committee The British Landship Committee formed during World War I to develop armored vehicles for use in trench warfare. The British proposed building "landships," super-heavy tanks capable of crossing the trench systems of the Western Front. The committee originated from the armored car division of the Royal Naval Air Service. It gained the notable support of Winston Churchill. Military vehicles Tank The tank was originally referred to as the landship, owing to the continuous development from the Landship Committee. The concept of a 1,000-ton armored, fighting machine on land quickly became too impractical and too costly for it to be realistically conceived. As such, the landship project proposed a smaller vehicle. The first conceptual tank prototype was for a 300-ton vehicle that would be made by suspending a "sort of Crystal Palace body" between three enormous wheels, allegedly inspired by the Great Wheel at Earls Court in London. Six of these 'Big Wheel' landships were eventually commissioned. However, even at a revised weight, 300 tons was considered impractical given the technology present, but the influence of the big wheel would persist in the "creeping grip" tracks of the first tanks, which were wrapped around the entire body of the machine. Mark I tank The constant revision eventually led to the creation of the first tank. While the Mark 1 and later variations were smaller than the initial behemoths engineers envisioned, they still used naval guns, including the QF 6-pounder Hotchkiss, later shortened to the QF 6-pounder guns. Schwerer Gustav Schwerer Gustav was a German super heavy railway gun developed in the late 1930s. It was the largest caliber rifled weapon ever used in combat and, in terms of overall weight, the heaviest mobile artillery piece ever built. With a length of 47.3 meters (155 feet, 2 inches), a width of 7.1 meters (23 feet, 4 inches) and a height of 11.6 meters (38 feet, 1 inch), the Schwerer Gustav weighed 1,350 tonnes. The gun's massive size required its own diesel-powered generator, a special railway track and an oversized crew of 2,750 (250 to assemble and fire the gun in 3 days and 2,500 to lay the tracks). By definition, the Schwerer Gustav would have qualified
