Iran deploys explosive 'suicide skiffs' disguised as fishing boats in Strait of Hormuz

"UKMTO has received confirmation that the vessel was attacked by an uncrewed surface vehicle (USV), and that the crew has been evacuated to shore," UKMTO said in a threat assessment.

The use of so-called "suicide skiffs" represents a growing asymmetric threat in the narrow, 21-mile-wide Strait, Chell warned, while highlighting the technological capabilities behind these attacks.

"The Iranians probably have use of radio remote control, line of sight, frequency hopping, or encrypted radio communication between the skiffs and the Hormuz shoreline," Chell told Fox News Digital.

"These can be jammed and tracked, but when there's 50 of these boats, it's hard to try to find them all along this shoreline or to find a 20-foot wooden fishing boat that is laden with explosives.

"The boats would be used to ram into targets and explode," Chell clarified.

Sources said that Iran had also deployed about a dozen mines, complicating efforts to maintain any traffic through the critical waterway.

U.K. Defense Secretary John Healey also said discussions were underway with European counterparts stressing the global economic stakes tied to the strait. Chell, however, questioned current defensive readiness.

"The drone defense fleets that the U.S. Navy would not have been set up to take these suicide skiffs out," Chell said.

"The U.S. would be using manned aircraft in order to take them out, which are fantastic at taking out a large target, but inefficient in taking out 50 boats at one time that are an average of 25 or 30 feet in size, laden with explosives.

As Supreme Leader Mojtaba Khamenei vowed to keep the Strait closed as leverage against the U.S. and Israel, oil prices continue to surge, with Chell also highlighting the geographic advantage Iran holds.

"The geographic layout of the Strait lends itself very well to relatively unsophisticated suicide skiffs, unmanned surface vehicles or USVs," he warned before describing how the area "lends itself to this low-cost, automatic, asymmetric warfare."

"The Iranians can disguise them as fishing boats and can be anywhere from 12 to 30 feet, and a boat could be of any description," Chell said.

"The skiffs are not autonomous, because the distance across the Strait is so short, and it's very flat across this waterway, the communication signal could be carried for quite some time via a line of sight," he added.
