In the early 1960s the Mark 3 entered service, to support the increasing weight of later Centurion models and also future plans for the Chieftain tank. These were the last Antars in service, remaining until the mid-1980s. The Mark 3 is visually distinct from the earlier models, the use of an 8-cylinder inline engine, the Rolls-Royce C8SFL; without the wide vee of the Meteorite the bonnet was much narrower.
