U.S. Navy’s sub-hunting drone ships will hit the open ocean this summer

Drones may known for their prowess in the skies, but thanks to some new developments at the U.S. Navy, they’ll soon be turning the open seas into their turf as well. A new video shows off an autonomous watercraft dreamed into reality from the men and women at the Defense Advanced Research Projects Agency (DARPA), all with the hopes of tracking submarines that haunt the depths of the ocean.

The very first prototype is meant to demonstrate the potential of what will ultimately become a fleet of unmanned ships, known as Anti-Submarine Warfare Continuous Trail Unmanned Vessels (to be pronounced “active” for short). The 132 foot long vessel managed to log a top speed of 27 knots during its test in Portland, Oregon, and it’ll be ready for open seas this summer when it launches from the California coast. The drone ship’s official christening is fast approaching on April 7, and the Navy seems pretty excited by the prospects of “an unmanned vessel optimized to robustly track quiet diesel electric submarines.”

In addition to tracking submarines, the ACTUV could prove useful in a number of additional operations.Everything from serving as a supplier to other ships, countering undersea mines, and aiding in the logistics of complex operations could be carried out with these unmanned vessels, especially given their ability to remain at sea for three months at a time without a human crew.

In preliminary tests, the drone has successfully tracked a submarine from 1 kilometer away, which the Pentagon says is a major improvement in the technology. “Picking up the quiet hum of a battery-powered, diesel-electric submarine in busy coastal waters is like trying to identify the sound of a single car engine in the din of a major city,” said Rear Admiral Frank Drennan, commander of the Naval Mine and Anti-Submarine Warfare Command.

ACTUV ships are also expected to help lower costs for the U.S. Navy, helping it save human capital and resources with this autonomous technology. It’s still unclear as to whether these water drones will be weaponized, but if you happen to see an unmanned vessel floating around the California coast this summer, don’t be alarmed. It’s just an ACTUV ship, waiting to do its duty.

Yet another study says AI is bad for elections, and the rabbit hole gets worse
AI may be an election bomb waiting for someone to light the fuse
Voters cast their ballots on Election Day

Another election, another study has concluded that asking an AI chatbot for political guidance is a spectacularly bad idea. Research conducted during Hungary’s 2026 parliamentary election found that ChatGPT and Google Gemini offered not just inaccurate but also inconsistent and unreliable voting advice. The chatbots misclassified voter profiles, overlooked relevant parties, recommended parties absent from the ballot, and sometimes produced materially different answers when given the same information repeatedly.

Samsung’s humanoid robot ambitions are real, but factories come first
Samsung’s new robotics division has humanoids in its sights, although its immediate business is far more practical factory automation
Robot Touch Human Finger

Samsung wants a place in the humanoid race, but its new robotics push begins with machines built for factories rather than homes.

The CEO-led RX robotics division will initially focus on manufacturing robots. Samsung has separately identified humanoids as a priority, although it hasn’t announced a commercial model or explained where one fits into the division’s immediate plans.

The future of AI may depend on this one behind-the-scenes change
Running Claude on Android.

Whenever a new AI model arrives, it's easy to get caught up in the bells and whistles. We talk about how much smarter it is, how quickly it answers questions, or how realistic its images have become. But here's the thing: none of that matters much if the AI can't reliably work with the apps and services people use every day.

That's why an upcoming update to the Model Context Protocol (MCP) caught my attention. It isn't a new chatbot or a fancy AI model. In fact, most people will never even know it's happening. But it could quietly make the AI ecosystem a lot healthier. If you've never heard of MCP before, don't worry. Think of it as a shared language that lets AI assistants safely talk to apps like Gmail, Slack, calendars, databases, and countless other services. Instead of every company inventing its own way to make those connections, MCP gives everyone a common rulebook.
