The Strait of Hormuz became easier to close and easier to reopen

How has the difficulty of closing the Strait of Hormuz changed over time?

Modern weapons make denial easier, but modern strike and mine-countermeasure forces also make reopening the strait more feasible.

Gunpowder first made it practical for shore batteries to contest the narrow waterway from fixed positions. Modern mines and anti-ship missiles let defenders threaten traffic at greater range and with less warning. Attackers have gained aircraft carriers, precision strike, mine countermeasures, and the ability to seize or suppress coastal sites. An inhabited island in the strait has a fortified settlement dating back to the eleventh century BCE, showing that control has long combined maritime and land positions. The result is an enduring offense-defense contest rather than a technology that closes the strait permanently.
