The Tank Mark VIII
also known as the Liberty
or The International
was an Anglo-American tank
design of the First World War
intended to overcome the limitations of the earlier British designs and be a collaborative effort to equip France, the UK and the US with a single heavy tank design.
Production at a site in France was expected to take advantage of US industrial capacity to produce the automotive elements, with the UK producing the armoured hulls and armament. The planned production levels would have equipped the Allied armies with a very large tank force that would have broken through the German defensive positions in the planned offensive for 1919
. In practice manufacture was slow and only a few vehicles were produced before the end of the war in November 1918.
After the war, 100 vehicles assembled in the US were used by the US Army
until more advanced designs replaced them in 1932. A few tanks that had not been scrapped by the start of World War II were provided to Canada for training purposes.
