The U.S. Navy is using underwater drones to find and destroy sea mines as part of the effort to keep Iran from closing the Strait of Hormuz. The unmanned craft, which cost $100,000 per unit, are 4 feet long and weigh just 88 pound, but they also include honing sonar, TV cameras, and explosive charges. Tehran has said they are willing to close the strait “in response to increasing sanctions and in the event Iran is attacked.” Meanwhile, the Department of Defense has said that Iran’s “military capabilities continue to improve.”
