Amid Global Race For Nuclear Submarines, Why Diesel Subs Are Giving US Navy Sleepless Nights

As oceans around the world become the new frontier of war, the US Navy has a new challenge. The build-up of highly capable diesel-electric submarines are making it very difficult to detect. The nuclear-powered subs, are often prefered for their long voyages without surfacing, produce a lot of noise. So, eliminating these sounds is the key factor to keep the subs undetected.

As a SSN637 and SSN688 class Sonarman for over 22 years, the hardest threat to detect and track is the DIESEL SUBMARINE built with the newest technology and a well trained crew and Commanding Officer. It has always been my personnel contention that our military planners had totally dropped one of the most stealthiest platforms to date. Some of the newest Diesel Platforms are even deeper diving than our current fleet of nuclear submarines. During my years of searching and tracking all classes of submarines, the Diesel Boat was by far the hardest even with our sonar technologies even towed-arrays. They are build for stealth and are a continue threat in areas like the Gulf of Mexico and all shores. Our planners should wake-UP.

For those who don't know Indian Diesel electric submarine defeated US Nuclear submarine in Malabar exercise without being Noticed. (MOCK WAR LIKE SITUATION)
Also Swedish Diesel electric submarine sunk US Aircraft Carrier in mock drill

Diesel electric subs are best suited for costal defense and green waters.
Nothing can beat nuclear subs in blue waters..

Actually in a training exercise, One of the Indian Navy's Kilo class subs managed to take out a Los Angeles class submarine (in a training session off the west coast of Indian Navy and the Swedish navy are some of the only Navy's to win a submarine combat exercise against the US Navy....

The good news is that the most and the best diesel electric submarines are serving in allied navies.

I work for a company that manufacture submarines, and defence technology in general. The obvious gamechanger is, like with the Akula II class negating the SOSUS network, that if a new generation of sub is quiet enough to not be detected by modern sonar suites until its just a few nm away, it can use electric motors and AIP to patrol bastion areas at very low speeds, but in greater numbers, effectively denying these areas to SSNs, even the latest ones. While also making standoff weapons useless unless a sonarbouy is dropped right on it or its pinged by dipping sonar or really effective active sonarsweeps like those from the russian Udaloy . They cannot shadow bluewater subs across long distances or chase down carriergroups, but at area denial, they are very effective as they can be almost completly quiet and are likely to obtain a firing solution on any SSN before they are counterdetected. After launching weapons it is another matter entirely of course..

Very interesting, informative and worthwhile video.

These are NO LONGER 'DIESEL' submarines - just call them NON-NUCLEAR. They have fuel cells and other various means of energy production and storage.

You do realize that the Nautilus was technology from more than sixty years ago and the Sonus array wasn't even contemplated until the late 1960s or fully deployed until the 1970s. As for diesel electric submarines they're decent coastal defense weapons but have neither the range or operational endurance to compete with modern nuclear subs.

Interesting video. I just got through re-reading the Tom Clancy novel Red Storm Rising. Submarine warfare is a major part of the storyline.

Russia has the kilo class “black holes”submarines for the U.A. Navy and NATO.

Most of the diesels I have ever seen, wait every single diesel I have ever seen was a pretty noisy beast. I believe the most dangerous noise when it comes to U.S.N. nuclear subs are not the reactors, which are sound insulated, but rather the cavitation of the propellers, which are about the most secret parts of ANY submarine. One good look at the angle of a propeller and the frequency of sound it gives off can be calculated. Once that is known any major power can track that sub no matter where it goes. Sound can travel for hundreds of miles under water, and once a sound's frequency is calculated approximately, any sub can be tracked close enough to destroy it. Diesel, nuclear, non-nuclear, man powered, rubber bands, baking soda, it doesn't matter.

That’s what the Americans and British want you to think! They are decades ahead in technology in submarine warfare! They have mastered it following Russia for 80 years.

[alextech]

Russia alone as of 2021 have 46 disel submarines. Submarines are much better for battle then surface ships because of today technology and rockets they are easy target.

In diesel electric submarine India is winning.

This proves, "All Old need not be Obsolete.!"

They are small use batteries underwater and does not need constant circulation of water to cool the reactors like in a nuclear sub.

This video needs to cover the advantages of lithium-ion battery propulsion system which can be recharged extremely quickly and also, has major advantages over traditional lead-acid battery that is used in most diesel-electric submarine.

JMSDF (Japanese navy) claims that it can fully recharge the lithium-ion battery bank completely in just 100 minutes every ~10 days and therefore, traditional AIP system is no longer needed. They also claim that it can do 20 knots underwater in sustained operation operating on battery power.

Acoustically/mechanically speaking, it's hard to beat fuel cell AIP propulsion system in stealth since it's basically a chemical engine, even with latest nuclear reactor design.

Also, China has just tested older Stirling engine AIP system with higher power output compared to traditional Stirling engine design.

It is getting close to the time when we will all find out.
