Why have many navies shifted away from a high-low mix toward one end of the spectrum?
Short answerLimited budgets encourage buying the high end first and hoping that conflict brings funding for lower-end equipment.
NotesA navy's budget can prevent it from buying both high- and low-end equipment. Buying the high end first preserves a capability that it would have little chance of acquiring once conflict began. The expectation is that wartime funding could then provide the low-end equipment. This responds to financial and strategic constraints, with the outcome depending on whether that additional funding arrives.
