Ukraine’s Security Service (SBU) said it has struck a Russian submarine in the Black Sea port of Novorossiysk using underwater drones, calling the operation a major breakthrough in naval warfare. Ukrainian authorities released video footage showing a near-surface explosion alongside a vessel, which Kyiv claims was a modern Russian submarine valued at up to $400 million. According to the SBU, the attack was carried out using “Sea Baby” underwater drones, a Ukrainian-developed system designed for stealth operations against naval targets. The agency said the blast left the submarine critically damaged and unable to operate. “This is the first time a...

This year’s Beijing Military Expo opened on June 5th, but it wasn’t the tanks, missiles, and other potentially lethal military equipment that drew reporters’ attention, it was a rather strange arowana fish swimming in a large water tank installed on site.

While you were out shopping Sunday for those last-minute holiday gifts, the Navy pushed ahead with its own vision of an underwater sugar plum: a fleet of “long endurance, transoceanic gliders harvesting all energy from the ocean thermocline.” And you thought Jules Verne died in 1905.

The U.S.-led exercises, which began last week, include operations by the unmanned SeaFox devices, which are equipped with sonar and an explosive charge designed to shoot and destroy mines. It is part of the Navy's plans to increasingly deploy automated surveillance and protection systems, including aerial drones. Navy commanders insist the exercises, comprising more than 41 nations, are not intended solely against possible Iranian threats. But Iran has previously warned it...
