Medium Mark A Whippet

In service 1918 - 1920s

The fastest British tank of the war, conceived to exploit breakthroughs that the slow rhomboids could only create.

Built byWilliam Foster & Co.

Development history

The Whippet abandoned the all-round track of the heavy tanks for a fixed rear barbette and twin engines steered by separate throttles - effective but exhausting to drive. In the open fighting after Amiens it showed what mobile armour could do, most famously when a single Whippet, Musical Box, ran amok behind German lines for nine hours. It pointed directly at the interwar idea of the cavalry tank.
