U.S. submarines must dive deeper in the future to preserve stealth and remain undetected by enemy sensors


U.S. Navy is rethinking the way it deploys its submarines, all to help them avoid detection by increasingly sophisticated Chinese sensors.

Submarine 20 Nov 2019

ARLINGTON, Va. – The U.S. submarine community wants to preserve its ability to operate undetected as a silent service under the seas while also contributing to the wider fleet and joint fight, the commander of the Submarine Force said earlier this month. USNI News reports. Continue reading original article

The Military & Aerospace Electronics take:

20 Nov. 2019 — Speaking at the Naval Submarine League annual symposium, Vice Adm. Chas Richard said his team is putting together a new Vision to outline the role of submarines in a future fight.

“It starts with something as simple as, we are never going to periscope depth again unless we want to; we are simply going to make that obsolete,” Richard said. “And more fundamentally, you can describe it as, get deeper.”

Another key idea is “our ability to avoid detection, our stealth, is our greatest asset. But when we think about what that means moving into the future, this becomes more than simply controlling our radiated signatures in the acoustic spectrum,” Richard said.

New Chinese Surveillance Ships to Detect Submarines

Navyreconginition.com says in its report “Three types of 927 surveillance ships entered China navy in 2018 and 2019” yesterday that according to photos circulated on Chinese internet over the past week, a new Chinese ocean surveillance ship has been completed and commissioned in southern China.

It says other two such surveillance ships are being built in Chinese shipyard. They are allo of SWATH designs extemely quiet especially when outfitted with electric motors. They are“especially useful for hydrographic surveying and research utilizing sonar and other sensitive acoustic equipment, and for locating submarines.”

They resemble U.S. Navy Ocean Surveillance Ships and may be equipped with advanced sonar arrays to detect and track submarines at great ranges. “Some can augment their passive listening arrays with low-frequency active arrays that send sound waves into the water to bounce off submerged submarine hulls to reveal their location,” says the report.
