Submarine

The US Navy scored a first as it carried out a submerged undersea launch of its new low-cost, long-endurance unmanned undersea vehicle (UUV) called HADALUS at Portsmouth, Rhode Island, where the vessel performed a series of sea trials.

AI-equipped helicopters went on the offensive off the islands of Hawaii as the US Navy and Lockheed Martin set two modified Sikorsky MH-60R Seahawk helicopters to hunt submarines using a new AI sonar system as part of the RIMPAC 2026 naval exercises.

For over a decade, Saildrone has been building extreme long-endurance sail/hybrid autonomous sea vessels for ocean data collection and mapping. Now, the company is adapting the tech to create a super-quiet, long-range sub-hunter craft.

Chinese scientists have revealed plans for a new tourist-centered panoramic-view submersible that will take people on an affordable trip 3,280 feet (1,000 m) into the deep – and they say the first prototype will be ready before the end of the year.

The US Navy has tapped Anduril's Dive-XL autonomous submarine for its Combat Autonomous Maritime Platform (CAMP) project, which aims at rapidly develop a fleet of underwater motherships capable of deploying smaller autonomous vehicles and torpedoes.

The Super Sub that creator U-Boat Worx calls the fastest, most advanced private sub ever built is about to be delivered to the first customer, giving a fortunate fractional-percenter what's sure to be an addictive, highly immersive new hobby.

Naval warfare goes a bit clingy as Lockheed Martin unveils its robotic Lamprey Multi-Mission Autonomous Undersea Vehicle (MMAUV), which can hitch a ride on friendly ships or submarines by latching onto their hulls to conserve power.

You can't even hide from drones under the sea now, with General Atomics flight-testing its MQ-9B SeaGuardian maritime patrol craft. It was trying out the new Expanded Sonobuoy Dispensing System (ESDS) for hunting submarines where they hide.

Robotic submarines are poised to become a major addition to the fleets of the world's major navies and as the technology matures more attention is being paid by the likes of the European Defence Agency (EDA) to making them quieter and stealthier.

Why have just one technological breakthrough when you can have two at the same time? The Royal Navy has installed for the first time a quantum clock into its XV Excalibur robotic submarine for extended precise underwater navigation.

The prototype Royal Navy robotic submarine XV-Excalibur has provided a glimpse of the fleet of the future by patrolling the waters at HMNB Devonport in Plymouth, England while controlled from a command center in Australia 10,000 miles (16,000 km) away.

The US Coast Guard has released the results of its Marine Board of Investigation of the Titan submersible tragedy that took the lives of five men and the 300-page document makes for damning reading in a tale of negligence and disregard for safety.
