This was an incredibly challenging video to make. The challenge came with getting the Navy to agree to the interview in the first place, then successfully navigating the interview without it being shut down. In the end, everyone was super professional and it was a really fun topic to learn about! I hope you enjoy, and thank you very much for considering becoming a Patron at (www.patreon.com/smartereveryday)!

My dad was a contractor for the navy with IBM for the skipjack class. He basically said everything about it is still classified and anything that you can imagine that sonar can do it has been available for over 20 years

​@kyle32121 Clearance typically lapses with a Job - it makes no sense for someone to retain a clearance unless they specifically need it. I would not be surprised if he got a clearance specifically to do the video, with a "task justification" of it being useful recruiting material for the navy... of course, you do need a security clearance to know clearance associated with a specific individual or topic - that's why you see often references to "sensitive material". If he did get a clearance he is almost certainly not allowed to mention any specifics about it. Interesting to speculate.

Why are they using the bearing rate graph in the first place? It is kind of unintuitive, what is the advantage? Can you feed it more easily to a computer? Or is it because of time? Can you better see POIs in nosy data? Great series, got me thinking a lot and thereby smarter.

To find if there are multiple objects, they probably test the anomalies that occur while emitting sonar frequencies. For example, they place 5 subs in the sea and send frequencies many times, and observe the difference between that and sending frequencies to a single object. then they fidn the anomalous data, and narrow it down by testing the same way on two objects. Then they know how to recognize multiple entities

A real eye opener for people interested in space travel. I'd imagine the operation of a nuclear submarine is very similar to a space capsule, or the International Space Station. I never knew how tightly packed every critical system is. Thanks Destin. Fyi, I'm starting to second guess my dream of migrating to the Moon and Mars in 30 years time. But then again, I guess a person can adapt to just about any situation in the name of survival.

I play too much Cold Waters, this is all very familiar. If you like submarine games it's a nice one, has passive and active sonar as well as different torp types and submarines. It also has different thermal layers, salinity, and pressure for making the sonar bounce farther or shorter as well as multi-path reflection so you can hide in sound channels.

I love your content but bristle each time you say "smart" or "smarter". Intelligence (i.e. "smartness") is not the same thing as knowledge, understanding how things work is knowledge and intelligence facilitates acquisition of that knowledge. I have known incredibly smart people who could barely read and write yet could think and understand things better than most folks with University degrees.

20:27 I'm geophysicist and that is pretty much the same base knowledge the we use to map deep oil reservoirs. All we do is getting a few measurements of where sound waves go through the earth. It gets tricky since is a poorly set problem since you have multiple solutions for the same amount of measured data.

This is probably as much as WWII or early cold war submariners knew about sonar. Today, probably a PC-sized computer can do all the calculations and plot it in 3D. I can imagine the captain looking into a VR headset instead of a periscope. :)

The submarine serie is great but this video in particular was by far the best. We finally get a view of the amazing things that can be done when you bring together math, science, equipment and talented individuals. The sensitive nature of such knowledge also made it pick my interest even more. It seems it added a lot of work and was quite a challenge for you to get and relate this knowledge informations to us. Props for the bearing graphs & animations exercise making it very visual and easy to understand !

If you’re getting returns from the surface and the bottom why not just take the depth of the submarine, calculate the amount of time it takes for sound to go to the surface and bottom then cross reference those times with your return signals? It sounds more then likely you’ll be able to “hear” the target then once you do jot it onto a piece of paper how long it took then when you hear more returns from the surface and bottom colliding into the other vessel use them to try to isolate the location?

This has overall been a pretty informative video. Having been a previous diesel power submariner from a allied country and sonar operator I would say that overall all the info you presented is pretty accurate. There are lots of other factors that get taken into account not to mention the actual operator skill involved in processing and determining what a contact is but great info from the limited info the navy provided you.

As a former US Navy Sonar Technician, I truly enjoyed being a sonar operator, maintenance technician, supervisor, and even instructor. Each role was incredibly rewarding. I truly feel for this chief, as he has formulate his answers based on multiple criteria: Simplicity, effectiveness, and sensitivity. He needs to simplify otherwise abstract concepts. He needs to make sure he effectively answers the question, even when the question itself is loaded with inaccuracies. Lastly, he needs to ensure he doesn't divulge any sensitive, privileged, or classified information. By the time he reaches the rank of Chief Petty Officer, he likely has the experience to do most of this; however, it's still a difficult task - especially when the level of sensitivity may change from one moment to the next. They did a good job, all things considered. I've had to do this myself, and I truly dreaded it. That's why I feel for the Chief in the video. It's not an altogether enjoyable task to answer civilian questions when a) most of the answers are multilayered, b) most of the answers are very abstract to the layman, and c) much of how the US Navy uses SONAR is classified.
