Which allied navies need mine-laying capability, and what can the Royal Navy currently provide?
Short answerMost need more capacity; Britain has aerial options and perhaps limited ship-based potential, but lacks the robust sea-laying force needed for precise wartime minefields.
NotesGermany, Denmark, Sweden, Finland, Britain, Australia, and other navies are all identified as needing stronger mine-laying forces. Air-dropped mines provide some reach, but ships and submarines can place a field more precisely and preserve known safe routes through it. The Royal Navy appears to retain aerial options and perhaps limited theoretical use of mine-countermeasure vessels, not a substantial dedicated sea-laying force. Neglected mine warfare capacity can reveal whether a navy has prepared for serious conflict or only peacetime presence.
