Why the final British F-35 total remained unsettled

Would future Tempest orders avoid the reductions often attributed to Britain's F-35 purchase?

Britain had not yet fixed or cut a final F-35 total; the eventual number would depend on operational need, cost, perceived war risk, and political consequences.

Britain had not repeatedly cut a settled final F-35 order. Governments had instead postponed the final purchasing decision while balancing defence requirements against other spending they considered more electorally attractive. The eventual total would follow carrier and combat needs, with threat perception and the political cost of being unprepared shaping the decision. Later production growth could reduce unit cost without removing that budget-and-risk calculation.
