Historical Reference:
Even before the start of World War II, the concept of twin-barrel tanks and self-propelled artillery units was repeatedly explored. There were tanks built in metal with two guns capable of firing salvos. Similar work was also carried out in the UK, where the military placed its hopes on the salvo-fire concept.
Both twin-barrel light tanks and much heavier vehicles were studied. One of these was a project under the provisional name Captain—an attempt to create a tank heavier than the FV214. It was one of the responses to information about the appearance of the Soviet heavy tank T-10. However, the project never progressed beyond the preliminary design stage, despite good armor protection and powerful guns. The main reasons for abandoning the project were its excessive projected weight and cost.
