A 19-foot American drone submarine rated for 19,700 feet sat dead in the water for more than a day at the mouth of the Strait of Hormuz, where the bottom runs 200 to 330 feet, until Iranian naval forces hauled it in, and the man who built it posted "rest in peace, little buddy"
1+ day, 3+ hour ago (597+ words) Sep 13, at 11:00am ET When a piece of American military hardware turns up on Iranian state television, the script is usually the same. Tehran calls it a trophy, Washington says as little as it can get away with, and the company…...
An 18.7-foot drone boat has brought back its first seabed maps for an Italian survey crew, holding its line on two 11-kilowatt pods that swivel and sweeping a strip of bottom seven times as wide as the water is deep, 210 feet across in 30 feet of water
1+ day, 8+ hour ago (1120+ words) Sep 13, at 6:30am ET Figuring out the shape of a harbor bottom has always meant putting a boat on the water with people standing on it. You pay for the boat by the day and the crew by the day, and…...
An 88-pound drone float went over the side of a sailboat above a trench north of the Antilles, sank 19,700 feet and climbed back five times, and a French lab got it to survive down there by giving up on titanium and building the hull out of composite
4+ day, 23+ hour ago (833+ words) Sep 9, at 3:30pm ET Every few months a number goes around about how much the ocean has warmed, and it gets quoted like somebody rowed out and took a reading. Somebody did, sort of. There are about 4,000 robot floats drifting out…...
A UK company just showed a drone boat that takes loitering munitions, mini torpedoes, drones or sonobuoys as cassettes two people exchange in the field without touching the hull, and it says an Anduril ALTIUS has already gone out of one
5+ day, 6+ hour ago (365+ words) Sep 9, at 8:00am ET The system’s patent-pending, and SubSea Craft’s announcement says a swap doesn’t involve modifying the vessel itself. The company lists loitering munitions, miniature torpedoes, aerial drones and sonobuoys as potential cassettes, all delivered from the same hull. “Operators…...
A 250-pound drone keeps working through 30-foot seas that would send a survey ship back to port, and the only moment weather can touch it is when it surfaces every six hours to talk, so if the pickup boat cannot come out it lands on the bottom and sleeps
1+ week, 1+ day ago (274+ words) Sep 6, at 7:30am ET If the weather turns, the robot lands on the bottom and goes to sleep. One number I am skipping: NOAA’s page gives the cruise speed two different ways inside the same sentence, so I am leaving speed…...
A 6.5-pound drone thrown off a dock by hand sprints across the surface at 8 mph, stops, dives 197 feet straight down for a reading and pops back up, and the Navy spent two days in August watching pods of them hunt other underwater drones in a harbor
1+ week, 3+ day ago (373+ words) Sep 4, at 2:00pm ET If you’ve been following our coverage of the Navy’s underwater drone problem, you’ve probably noticed the solutions keep getting bigger. A seabed fence stretching nearly a mile across a harbor floor. A 34-foot drone submarine that fires…...
A 39-foot drone boat wrapped in solar panels from bow to stern carries a turret under an armored hatch in its nose, gathers 24 kilowatt-hours a day against the 2.5 it spends holding position, and the yard that built the hull makes wake boats

A 39-pound tube shaped the way American sonobuoys have been shaped since 1942 pinged at underwater drones this summer, gave away its own position doing it, and sank, while a 21-inch reel unspooled nearby into a listening array and never made a sound
1+ week, 5+ day ago (732+ words) By: Chema Bonilla Díaz Sonar comes in two flavors and they want opposite things. Passive sonar listens and says nothing, which keeps you hidden and leaves you guessing about how far away anything is. Active sonar pings, tells you exactly…...
An 8.5-foot drone has been crawling the seafloor 13,100 feet under California on two watts, driving 32 feet at a time and then sitting 48 hours while it counts the oxygen the mud is breathing, and it has covered 6.8 miles in seven years
