  • 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)!

    • @@tinchote It's the fact that this stuff is for civilian consumption. The military is usually twenty years ahead of whatever is declassified, so this video sets the bar. If Iran or NK are 10 years ahead of this, they can estimate that they are 10 years behind us. It's also scary for them to know how many American civilians actively educate themselves about military hardware and tactics, and that those people form communities who share intelligence with each other. Propagation of information is one of our strong suits. Especially among teenagers. That suggests a future where young Americans are more ready for war than our adversaries. All of these ideas add up to a great deterrent. Funk is right. Dustin himself realized his video on the Future of Warfare was a weapon in the cyber domain, just one of the domains of modern wars, and it's the one the military needs civilian help to operate in.

    • There is Stuff - fairly common everyday Stuff, not this "Cold War-Spy-Stuff" rather than f. E. the Time Plan for the Mess Hall - that is classified. And, there is also Stuff, you are not even allowed to answer in any Way - so also not denying it. It is often People say something Stupid just to avoid any further Questions and even "keeping silent" would be too much of an indicator. Knowing this, mainly all you can find on YT and such is outdated (WW1-Trechtactics), common knowledge ("THAT WAY ROUND you have to hold the Rifle. THAT WAY!") or common Sense ("All the Guys around you wear blue. Your Arm you see on Screen seems to wear Blue. So guess what you gotta do with the Red ones and what not to do with the blue ones?"). In that case, the Conversation went pretty fast into "How to find out and seperate Contacts" - which is highly classified - and so the Guy showed his CO "'s all right, I know how to handle this" and just went over to the Basics, away from the deep questions. Also, that Way he provided all Answers and everybody knew that any further Questions go into the "No-Go-Zone". I am more impressed of his Leadershipskills which I had not expected from this Guy.

Send a ping wait for response for ranging, listen using a phased array antenna for direction. But once you add in one or two or five confounding physics phenomena, rotating reference frames, the Doppler and lensing, etc, this stuff gets real hard to visualize real quick, and you need some signal processing to help you out.

    • I am a Navy vet and I will tell you one thing that is true about every sailor, we love proving our superiors wrong. I used to walk around with multiple policies in my pocket because there are "old" policies that higher ups still think are enforced and they have been changed or they simply don't know about. for example: I was a sailor who was sent to Iraq to help support Army operations, we wore Army uniforms, Army uniforms have some different standards for wear than Navy uniforms. Instead of issuing a whole new set of regulations for the uniforms the Navy simply issued a policy to basically state "The Navy members who wear Army uniforms will follow the Army rules for wearing said uniforms". My favorite was for backpacks, in the Navy the backpack had to be black or dark blue and could only be worn slung over one shoulder or carried. You could not wear a laptop bag slung over a shoulder or across the chest it had to be carried. The Army on the other hand didn't care how you wore the backpack as long as it was black and left your right hand free (for saluting) and laptop bags were authorized to be worn accordingly and had to be black. When I got back from Iraq I still had to wear my Army ACU's because they told us to leave all our other uniforms at home. I was waiting to transfer to my next command and the amount of times I had to whip out the regs because some Chief or Officer would stop to scold me for wearing my laptop bag was unreal. The satisfaction I got watching many a blood vessel bulge in some chiefs foreheads was immeasurable though. most were cool and were like "oh cool, lemme write this down so I can tell the other chiefs"

  • I am a former sonarman on an Arleigh Burke class destroyer, and I must say that this is a very good video when it comes to explaining what I used to do in the Navy as an STG 2 Sonar Supervisor. Yes, lots of math and knowing the "signature" of every single ship and sub that exists (or at least those that we know of), plus all of the biologics and underwater topography (and oceanography). It does take a lot of mental aptitude to first identify the contact that you're hearing (you need to know the specific frequencies that every vessel emits into the water), and then you need to do the trig to actually figure out where it is in the water (i.e. time and space), and what direction it is moving (and at what relative velocity). And you must do this using only heard frequencies in the water, while also allowing for real-time changes on our part or theirs. We generally had 3-5 minutes to first identify the contact, and then another 5 minutes to determine where it is (and what speed/heading it was on). By the time that I left the Navy, the buttons on my calculator were worn entirely unreadable (and I bought it brand new when I checked aboard my ship). I did two deployments to the Gulf, plus an INSURV. My ship came in second for the Bloodhound Award after INSURV.

I worked in the radio room, the electronic surveillance room, and the control room testing EMI levels on all types of systems on the subs. I got to see how the sonar worked, while sitting alongside the ship’s crew. Being in the control room was INSANE! I even went on sea trials with these guys, ate & slept with them for a whole week. It is definitely an experience that I’ll remember forever. Talking with the crew members about their lives and getting to know them like everyday people was an even better experience.

  • One way you can potentially solve the multi-return issue is using what's called a band-pass filter. If you know what the object you are hunting is made of, you can anticipate the frequencies that will have the highest energy on return. Steel will return different dominant frequencies than say ice or mud. You can frequency filter your return data to give you the true target.

    • I imagine if you have a passive cue you can at least filter out the active returns that arent in a similar azimuth/elevation as as the passive cue. But still, the passive cue has it's own multipath problems. Its like, if you know where it is, you know where to look, but if you know where it is you dont need to look. Hmm. Im sure there are fancy computers that take all these things into account and fuse the data from multiple sensors and narrow down the error possibilities automatically. Neat stuff.

  • When I was stationed on the USNS Guantanamo Bay, Cuba we used to drop a sonar down to 11000' giving us the different temperatures in the water. We had a sonar set on the bottom of the Caribbean that we could set to test ships' sonar operator on that particular piece of equipment for a period of 8 hours. In other words, no swapping out operators because they don't all work the same way. These tests went on for up to 3 days so we could test all sonar operators. Also, our shore-based operators would give bearing and range to a target in degrees, minutes, and seconds for a very accurate reading and the had to be within 5' of a target attached to the jackstaff on the bow of the ship (a DDE). There was one time when the ship had to turn so that it would not encroach into Cuban waters, as the target was disappearing I let CIC know I was losing the target but could see the light on the top of that jackstaff. I was told after the test was done the guys on the ship laughed at my response until the shore-based station told them that I was 1/2" off of the center of the target. That shut them up, and I said I could see the light again then read my reading and they were told I was dead on the target. Someone in CIC learned a fast lesson that day.

  • 18:13 this got me thinking about this question. And my guess would be that because the depth of the submarine is (hopefully) known you know the distance from the ice and the floor to an extent they are gonna have to know the terrain of the seabed in-which they are operating in which I imagine they do. You can figure out which return is gonna be the vessel contact. You already talked about algorithms to filter out biological noise and identify different ships don’t see why you couldn’t have it also auto correct for the multiple returns based on depth and distance to sea bed.

He now feels closer than ever to being a submariner and is in absolute LOVE with this series. Thank you for allowing his dream to become somewhat of a reality vicariously through you! Much love and Holiday Blessings from Texas. We ARE Smarter Every Day with your channel. Thank you and God Bless you and your family.

I do wish he gave more info as he was still far away from the line on many aspects, but seems the sonar sup was too scared to do that (don't blame him) since even public info can be class'd and while you can google it if he talks about it he'd be in jail.

  • I want to say just how great this series of videos is but I only speak one language and sadly, there are not enough words the English language to express just how good it is! As a former member of the UK Armed Forces, on occasions, I have spent some time in a tin but as this has been either on exercise or operational, neither the time available or circumstance (or being honest, simply wanting to take the opportunity to get your head down post Db) made it appropriate to do much else while aboard. So it has been really enjoyable to see what else is going on through your videos. Kudos to the US Navy for working with you on this series.

    • Because you're not learning. People watch these videos on KZhead and then think they're super confident about whatever it is--that they now can do or understand the thing. But studies have shown that after about 24 hours to 1 week, you've learned nothing. Further, we tend to overestimate our ability to understand or do things when we watch other people do them in videos. "Oh I can do that--it's simple now that I know how". But knowing how and actually developing the physical or mental ability to perform that task are very different things.
