Strait of Hormuz, August 6, USS Thomas Hudner (DDG-116), Lewis and Clark class cargo ship USNS Amelia Earhart (T-AKE-6) and USCGC Charles Moulthrope (WPC-1141) with L3Harris Arabian Fox uncrewed surface vessel (USV) in the foreground.
The Drive has a post discussing 5th Fleet/NAVCENT’s pioneering work with Unmanned surface systems (UAS) and the creation of Task Force 59.
Coast Guard Webber class patrol craft are prominent in the operation as they have been in previous UAS operations. I suspect this is because the WPCs are readily available to the 5th Fleet commander. Their size and maneuverability make them easier to operate in close proximity to the small UAS (and in the vicinity of Iranian Revolutionary Guard Corp (IRGC) small craft). They are heavily armed enough to prevent the IRGC from stealing the UAS. They have tried to do it in the past.
Specs on the 13 foot L3 Harris Arabian Fox (40 knot maximum speed and 36 hour endurance) lend credibility to the long-range reported for Ukrainian Kamikaze UAS, up to 450 nautical miles (approximately 833 km).

Hell, won’t be long before we won’t need a Coast Guard. Civilian operators can run this drones. Can’t get millennials to come to the office? Data-Link from their couch at home.
