How the F-35 programme narrowed later procurement choices

Were later F-35 purchases effectively rigged even when the aircraft met the requirement?

The decisive advantage came earlier, when partner commitments reduced competing aircraft programmes and made later F-35 purchases the natural result.

The argument is not that each later F-35 competition required overt manipulation. Partner nations invested in the programme early, making them more likely to buy the aircraft after committing money, industry, and planning assumptions. At the same time, that multinational commitment reduced the incentive and market for rival Western combat-aircraft projects. The result is procurement lock-in created years before a purchase decision, reinforced by both a lack of alternatives and sunk costs.
