The Vickers Main Battle Tank Mk. 4 later known as the Vickers Valiant was a main battle tank developed as a private venture by British company Vickers for export. Its development began in 1976 and ended in January 1984. Although the Valiant did not enter production, its development provided valuable experience in the production of an aluminium-hulled, Chobham-armoured tank in the 40 tonnes weight range. A further development of its turret was later used for the Vickers Mk. 7 MBT.
