Nuclear submarines carry out multiple types of missions, but no matter the mission, it's vital that they remain hidden in the ocean's depths.

Navies rely on quiet robotic submarines. Discover the EDA's €4.8M SPHYDA project exploring advanced hydroacoustics and stealth tech for autonomous underwater vehicles (AUVs).

Diesel-powered submarines present a challenge that may seem paradoxical at first. Their engines require oxygen to operate, yet these vessels routinely travel beneath the ocean surface. Naval engineers ...

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 ...

While diesel engines don't need spark plugs, they do need air ventilation for proper combustion. This is a problem for vessels traveling underwater, such as submarines. Yet diesel submarines exist and ...

Diesel engines cannot work without oxygen, so how do diesel submarines operate when they're underwater? Their propulsion ...

Ukraine said Monday it carried out an underwater drone strike that critically damaged a Russian Kilo-class submarine docked in the port of Novorossiysk, marking the first known attack of its kind. The ...

Ukraine is under intense pressure on the battlefield and at the negotiating table, but underwater it appears to be a growing threat to Russia. New satellite imagery shows damage to a Russian naval ...

Dec. 25 (Asia Today) --North Korea released images of Kim Jong-un inspecting what it called a nuclear-powered submarine construction project, a move analysts said was aimed at casting South Korea's ...

The new system relies heavily on passive acoustics—technology that simply listens, rather than sending out signals of its own such as sonar pings. Australia is building an integrated undersea ...

Ukraine's internal security agency said it used an underwater drone to damage a Russian submarine. The agency described the attack as a first, potentially signaling a new chapter in drone warfare.
