From 'AFV WEapons Profile 44 - Ferret and Fox
AVR and TV 1000
The original AVR design put forward by FVRDE envisaged a tracked vehicle. However in 1963, FVRDE
proposed an alternative, six wheeled AVR, weighing 13.6 tonnes, and armed with Swingfire missiles and a
76mm gun. The design took two forms, turreted, and turretless, the latter being attractive for a reconnaissance
vehicle, as it resulted in a reduced silhouette. In both cases, however, the wheeled AVR was to be skid
steered, like a tracked vehicle. The use of skid steering in the AVR followed the construction of the TV 1000, a
20 tonne test vehicle, designed in 1956-57 as a possible basis for a wheeled tank, the thinking being that the
hull could be wider in relation to it's overall width, because no space was needed for the turning of it's wheels.
However, the TV 1000 suffered from the same turning problems as exhibited by tracked vehicles, and in
addition, suffered from rapid tyre wear, and poor stability when running fast on roads.
The AVR proposals were rejected in 1963,when it was decide that they were too heavy, especially for air-
portability, still considered important by planners. Therefore, in 1964, two new proposals were put forward by
FVRDE. One was for a family of light tracked vehicles, which became the CVR(T), the other being for a series
of light, 6 to 8 tonnes, six wheeled vehicles with skid steering. This latter proposal was rejected, in part as a
result of trials conducted in 1964, which demonstrated the fundamental weakness of the skid steering of the
TV 1000 on soft ground."
