Navy Sends Robots to Take Out Iranian Mines in Strait of Hormuz: Several Successful Detonations Already Reported

Drones are probing the Strait of Hormuz for Iranian mines as the U.S. military works toward reopening the key waterway.

The need to get rid of the mines comes as the U.S. Navy is in transition from its fleet of minesweepers, four of which were recently retired, to sea drones, according to Fox News.

“To be honest, that the minesweepers retired was never a concern to me, because we had brought in newer technology,” retired Vice Adm. Kevin Donegan, who previously commanded the Navy’s 5th Fleet, said.

Drones are working both above and below water.

Underwater drones map the ocean floor and use high-resolution sonar to discern which objects might be mines.

“They kind of look like torpedoes and they map the bottom,” Donegan said.

Surface drones tow sonar systems through narrow lanes, accompanied by helicopters that scan for mines near the surface.

Bryan Clark, a defense analyst at the Hudson Institute, said finding mines is just the beginning.

“The mine neutralization part is really the long leg of the process,” Clark said.

Remotely controlled systems are used to disable a mine by either blowing it up or punching a hole in it so that it sinks.

Trump’s got Iran’s number—warning ’em off while we surge drones & ships to clear their mines from the Strait of Hormuz. Navy’s smart pivot from old sweepers to unmanned tech keeps oil flowing. Weakness? Nah, strength! Who’s with me?https://t.co/P4Rq2Ch2F0#MAGA #AmericaFirst…

“You’ve got to then retrieve this thing with EOD personnel,” Clark said, referring to explosive ordnance disposal teams.

Ensuring that a waterway is mine-free could take weeks or months.

“The finding part, you could do within a couple of weeks,” Clark said.

Donegan said it remains uncertain what Iran actually did.

🇺🇸 The U.S. is sending autonomous sea drones to sweep mines in the Strait of Hormuz, and the timing says everything.

The Strait carries roughly 20% of global oil traffic. One successful mining campaign and energy prices spike worldwide within hours.

“When somebody says they mined it, you have to go validate if that’s even true, and that takes time,” he said.

A report from The Wall Street Journal said that a Common Uncrewed Surface Vessel, a drone that tows a new floating sonar system called the AQS-20, is part of the effort to detect mines.

The drone goes back and forth scanning 100-foot-wide swathes of the sea.

Battery-powered sea drones dropped from ships are also used to scan for mines, The Wall Street Journal reported.
