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 (https://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.

As a Submariner and Sonarmen, you're speaking the language of my people Destin. And to make it really sink in, they allow a qualified broadband operator, often the most junior enlisted guys onboard who could be just out of high school, to drive a 6 billion dollar warship.

Sucks for Russia and China, because they can't pass by Japan. The straights are too narrow. Japan is like a big sub defense shield. That is why they use Murmansk and Sanya for subs. geography is much better at those ports.

I am feeling a bit confused, I as many others was experimenting with an ultrasound meter on step motor... And that's how I imagined it... beeping 360, to get a nice layer of distances. But I never really figure out how to get 3d image. Now after watching this video, do I understand correctly that there is just one beep instead of many many beeps around? So there is no good way to get really 3d information about other objects?

I knew of the Underwater Sound Channel. Years ago, I found this video lecture on YouTube that explored the Roswell 1947 incident but from a non-conspiratorial way where the lecturer explained that Maurice Ewing found out about a depth range where the temperature allowed a sound to travel a long distance w/o losing much signal strength. The lecturer went on that because of this discovery, the USAF during WWII had pilots carry orbs onboard their fighter planes to throw overboard because they had a crush depth in the underwater sound channel. Maurice Ewing also discovered an upper atmospheric sound channel at a certain height in the sky. This led the US Army to listen for Soviet nuclear weapons tests with Operation Mogul.

Okay, so Destin would have been easier been able to explain all these things without visiting the submarine (and having to deal with military personnel unwilling / unable to talk about things that are known to the public). Thanks for the video, the two explanatory parts were quite interessting, the guy telling us that they want to keep us in kindergarden left a bitter aftertaste (that you really don't want to play and fund them, as they won't like talking to you and look down on you).

I like to imagine when he got the footage back from the navy, they didn’t cut everything out, they just replaced it with a silly ‘technical difficulties’ style screen that says ‘Sorry, that’s classified’ with silly music playing for the entire duration of what would be the classified part, that would get old so Destin had to cut it out.

I love how cautious they were in this. A lot of what they discussed, and a lot of things they didn't even touch, are already addressed in PC games like 688 Attack Sub way back from 1989. There are more modern games that literally have repeated the mechanics of sonar in Jane's 688(i) and Sub Command. They had things like thermoclines, salinity, depth, pressure, etc. Nowadays, for the most part, the sonar on submarines still works the same way, except they are listening for things differently and use different methods to determine where a contact might be. ;)

This series really takes me back! When I was a ST we had our own sonar room with a door which gave us some privacy to goof off while underway. In the new subs I guess the sonar guys are just out there in the control room like lowly FTs? How sad! Also, its a shame they didn't let you sit at the broadband stack to hear some trawlers and biologics

I know how you'd remove the interference from the ice above and the floor below. You'd need to mirror the environment across the boundaries (like looking through a mirror). With that there are some simple geometric ratios that arise, and you can filter out any times that are roughly fit within that. It's actually quite similar to that special relativity experiment in that regard, actually.

On the multi-path, you can probably ping multiple times and simply get the baseline for the seafloor (assuming also that the topology/map of the ocean is a given and you know your position you can pinpoint the configuration below and take your depth) below and ice above (which is harder than the seafloor because it changes more than the seafloor and there really is no mapping reliable enough but you can still get the depth of the sub and therefore the relative time it would take for a ping striking the ice at an angle). Those two are more predictable. I would also assume that the ping is not singular. You then factor in that the object you are tracking is in motion (while the sub is the one in motion relative to the static solid ice above and the seafloor below). So the best way is to take multiple samples with these things in consideration and subtract the more static pings that come back.

They most likely can't go deep on the frequency discussion because opposing forces can make use of that to derive the range and how those ranges are interpreted. You can then design countermeasures to mimic similar objects emitting what is identified to be non-threats by their algorithm/standards. You can then basically pasa thru at least one defense layer (but there will be countermeasures for that countermeasures so better safe than sorry), among many layers.

Now what I'm wondering is, in active sonar, is the emitted pulse isotropic or directed? I'm assuming isotropic as that's how it's usually depicted, but can a sub do directional sonar the same way radar is done?

Watched every episode of the "Smarter Every day" submarine series today. Every entry was incredibly fascinating. I was left with two questions that Destin didn't ask. If fire is their number one threat, then why are there wood panels and other flammable materials all over the ship? The other question, that may be more of why I don't hear NASA and others planing deep space human travel, and that is, it seems that submariners seem like the perfect (already trained) people for such missions to Mars and other multi-month long trips.
