Mine warfare and control of Mediterranean chokepoints

Mines gave small warships a strategic way to control movement through the Mediterranean. Even a threatened minefield could disrupt operations in confined water and force an opponent to invest in clearance, specialist equipment, or escorts. Clearing a technically passable channel was insufficient if merchant crews did not trust it. The passage points to the 2026 Strait of Hormuz blockade as a contemporary example of the difficulty of restoring commercial confidence. Many navies had already discarded mine countermeasure capacity while expecting future replacements to fill the gap. Italy's interwar destroyers retained minelaying or minesweeping flexibility alongside torpedoes and guns, giving them a way to influence access as well as fight surface actions.
