The Vickers MBT is a series of main battle tanks (MBTs) developed as a private venture by Vickers-Armstrongs for export. The design makes use of proven components such as the L7 gun of the Centurion, and the Leyland L60 multi-fuel engine, transmission and fire control system of the Chieftain. A large number of tanks were also built by India under licence as the Vijayanta.
