In December 1961, the G.S.O.R. (General Staff Operational Requirements) 1010 for a wheeled armored reconnaissance vehicle were released. The first developments were presented in January 1963. It was a three-man combat vehicle weighing almost 14.5 tons. Later, there was an alternative project. It was heavier and also had a more powerful armament and better armor protection.
In terms of characteristics, the GSOR 1010 FB was between a light and medium tank. The machine was relevant for combat operations in desert terrain. This was also the main reason why the work did not progress beyond the sketches. The Army needed a reconnaissance tank, two of which could be carried in an aircraft. The GSOR 1010 FB was abandoned, although a full-fledged wheeled tank has since appeared more than once among British designs.
