According to Admiral James Foggo, the commander of the US Naval Forces Europe, the Yasen class submarines are "very quiet, which is the most important thing in submarine warfare". [27] It's claimed that Severodvinsk is far quieter than previous Russian SSNs, capable of 20 knots while running quiet, which is equal to the Seawolf class [ 49 ] and ...
Silent running is a stealth mode of operation for naval submarines.The aim is to evade discovery by passive sonar by eliminating superfluous noise: nonessential systems are shut down, the crew is urged to rest and refrain from making any unnecessary sound, and speed is greatly reduced to minimize propeller noise.
The Kilo class represents a huge leap forward in the PLAN submarine fleet. Originally a Soviet design in the 1980s, the Kilo-class was meant to be one of the world's quietest class of submarines. With 12 Kilos operational by 2006, it is unclear whether PLAN will buy more of these potent vessels.
Created to find and destroy Soviet submarines, Thresher was the fastest and quietest submarine of its day, matching the smaller, contemporary Skipjack class. She also had the most advanced weapons system, including launchers for the U.S. Navy's newest anti-submarine missile , the SUBROC , as well as passive and active sonar that could detect ...

The US Navy is currently testing a robotic ship that would be able to autonomously hunt enemy diesel submarines. Originally conceived as a DARPA project, the Anti-Submarine Warfare Continuous ...
Nuclear attack submarines. China's interest in nuclear submarines dates as far back as the mid 1950s, immediately after the US Navy commissioned the world's first nuclear submarine, USS Nautilus ...
The Gotland-class submarines of the Swedish Navy are modern diesel-electric submarines, which were designed and built by the Kockums shipyard in Sweden. They are the first submarines in the world to feature a Stirling engine air-independent propulsion (AIP) system, which extends their underwater endurance from a few days to weeks. [2]
