  • 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.

  • 15:07 "so you're also doing...." Xray? infrared? Microwave? Electromagnetic? It could be any of these or something else. I personally like the last one. Maybe worth a FOIA request?

    GiffyGiffy19 soat oldin
    • So, I made a huge error. xray, infrared and microwave are all electromagnetic energy. Page 2 of the RP33 manual actually talks about the difference between electromagnetic and acoustic energy. Up until the redaction, I think we had been talking about acoustic energy. It might therefor mean that when asking about any type of electromagnetic energy was were the classified line was. Just a hunch.

  • It’s kind of pointless because every sailor probably knows these concepts no matter what country’s Navi they belong. Only civilians are kept in the dark about this. As for the technology, well that’s a different thing. Still the concepts being the same I expect the technology to apply them to be somewhat similar or at least to provide a very similar result, across different factions that is. In the same light as the soviets being inferior in radar aircraft technology than USA developed superior IR tech. In the end they achieved the same results using a different tech. Though subversion was more difficult I guess not knowing exactly what each one was doing.

  • A ton of info in this video. Neat stuff. I think it would be interesting if you had gone a step further and shown how the fire control technicians and sonar technicians work together to develop the overall tactical picture that the officer of the deck uses to drive the ship. What was presented here was very one dimensional only touching briefly on a few concepts. Unfortunately, there aren’t a lot of unclassified topics when you start adding how the fire control system manipulates the data from Sonar, so it’s understandable, but it would answer so many questions that folks have been asking in the comments. Stuff I want to share, but just like the chief and XO here, I’m buffering. LoL. Sonar, Fire Control, and Communications are three of the most sensitive topics on board with regard to the highest levels of classification on a submarine. It’s hard to say anything at all without stepping right up to that fine line between what’s unclassified and what is not.

  • 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

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?
