What rebuilding Britain's tank fleet would require

Would rebuilding a British division lead to a larger tank fleet?

A substantial expansion would require new production, and a newer tank would make more sense than reproducing Challenger 3 when starting that investment.

A substantial increase in tank numbers would require new production capacity. Once Britain pays for that, a newer design would make more sense than rebuilding an ageing Challenger platform. A possible tank project associated with AUKUS is mentioned, but its future is uncertain. Joint development also has to accommodate Britain's concern with shipping armour overseas, which places different demands on weight from French and German expectations of deployment over land. Domestic work share matters because a project that spends British money without building the vehicle in Britain invites opposition. Britain, Italy, and Japan are suggested as another possible partnership.
