A 15.6-pound drone the size of a toaster oven doubled how many reef survey runs a NOAA program finished in a day, and the American government had to file a public waiver first, certifying on the record that nobody in the country builds one of them
11+ hour, 6+ min ago (1168+ words) The federal government is supposed to buy American. It is the default setting on nearly everything it purchases, and when an agency genuinely cannot find a domestic option, it has to file a public waiver saying so. NOAA filed one…...
A 661-pound drone with no cable and no pilot can hang in front of one weld for 24 hours, and the reason is twelve kilowatt-hours instead of one, because the hard part underwater is not swimming anywhere, it is standing still against the current while your sensors hold steady
1+ day, 6+ hour ago (901+ words) Most of the underwater drone news over the past two years has been about distance. China is testing uncrewed submarines roughly 148 feet long. Australia handed the US Navy a drone that swims about 1,240 miles and ships inside a standard container....
A 55-pound German drone shaped like a penguin goes on display in Denmark this week, a 44-inch machine that hits 10 knots because its body has 28 times less drag than a pipe — and it flags objects on the seafloor with onboard AI before it even surfaces
1+ week, 1+ hour ago (633+ words) The torpedo shape has been the default for underwater vehicles for more than a century. It’s cheap to build, easy to seal, and it slides through water well enough that nobody felt much pressure to improve on it. A Berlin…...
A 6.6-pound Canadian missile the length of a baseball bat chases a laser dot somebody on the ground is holding on the drone, blows its fragments straight ahead instead of sideways, and the man holding that dot gets twenty-five seconds
1+ week, 1+ day ago (1716+ words) The math on drone defense has been broken since roughly 2022, and everyone in the business knows it. You fire a $4 million interceptor at a $35,000 drone, you win the engagement and lose the war, because the other side can build a…...
A 10-ton Ukrainian drone submarine that is wider than it is tall sat on a stand in Paris built partly to hunt other underwater drones, and six weeks later the US Coast Guard asked American industry for anything that could kill one
1+ week, 4+ day ago (1375+ words) There is a hard engineering reason for that, and it has nothing to do with styling. Which is what makes the machine a Ukrainian company parked on a stand at Eurosatory in Paris back in June worth a second look....
A three-ton American drone submarine survives 19,700 feet by letting the sea straight through it, stays down ten days at a time, and its whole outer shell prints in under two days, which is why a factory can turn out 200 of them a year
1+ week, 5+ day ago (556+ words) The published numbers are compact. The Dive-LD measures 5.8 meters long, about 19 feet, with a 1.2-meter diameter, roughly 4 feet, and a dry weight of 2,720 kilograms. Call it a three-ton cylinder about the size of a small delivery van, minus the wheels…...
A 9,260-pound American drone swims out on its own battery, grips with 1,000 pounds of force and swaps its own tools out of a compartment in its nose, and nobody drives the arms because radio does not work down there
1+ week, 6+ day ago (1162+ words) Underwater robots have always come in two flavors. The swimmers cover long distances on battery power and take pictures, and the workers hang off a thick cable beneath a crewed ship and actually turn wrenches. You picked one, because no…...
An Alabama yard just launched a 694-foot steel box that works by sinking on purpose, flooding its own tanks until a destroyer can float over the deck and then lifting 18,000 tons clear of the water, and it lifts what a 1943 dock lifted
2+ week, 5+ hour ago (352+ words) Getting your car fixed usually means putting it on a lift. The Navy has the same basic problem, except its cars are 500-foot warships, and there is no lift on earth you can bolt to the seabed under one. So…...
A 33-foot drone sailboat doing 5 knots with nobody aboard picked out a smuggling vessel in the Caribbean, stayed on it and handed the track to the Navy, and the ship that turned up took $81 million of cocaine off it
2+ week, 12+ hour ago (873+ words) Catching drug boats at sea has always been a numbers problem. The Caribbean and the Eastern Pacific add up to millions of square miles of water, and the Navy and Coast Guard own a painfully finite number of hulls and…...
A 132-pound American drone two people can lift off a tailgate went into the North Sea instead of a crewed survey ship and picked out everything down to a one-meter cube on the bottom, and its own maker says do not use it below 20 meters of seabed
2+ week, 2+ day ago (1265+ words) You have probably run into the line that we have better maps of Mars than we do of our own seafloor. It gets repeated at every ocean conference and in roughly every funding deck. GEBCO, the body that actually maintains…...
