Vickers proposed improving the Valentine tank in 1943.1,5 It would be patterned after the Valentine as much as possible and have a bigger 3 man turret.1,4,5

To speed up production the road wheels were made the same size.1 Vickers gave the design to Birmingham Carriage & Wagon who then passed it on to Ruston & Hornby.1,5 The pilot was completed in mid-1944.1

One model had a GMC engine with an AEC gearbox and the other a Rolls-Royce Meteor engine and gearbox.4 The Meteorite engine could take diesel or petrol.5

The turret was 2 casts bolted together.1 The front of the hull was also made of castings.1

Only reached prototype stage as the war was close to ending.1


  • Valiant: Had GM diesel engine.5
  • Valiant II: Had Ford V-8 or Rolls-Royce Meteorite (de-rated Merlin) engine.5
