If another world war began now, would navies run out of missiles or ships first?
Short answerMissiles first.
NotesThe answer is immediate and unqualified: missiles. No estimate is given for stockpile depth, expenditure rates, or how quickly shortages would appear. The exchange still warns against treating hull numbers alone as a measure of how long a fleet can fight. Its value lies in the direct comparison, with the detailed logistics left unresolved.
