@@marcteenhc9793 Ever heard the term "A drop in the Ocean"? You are by far a much more polluter of the world than you are aware. "Ignorance is bliss" and all that.
@@marcteenhc9793 Thanksn't for the absolute beta comment. Look at all the wrecked ships at the bottom of the ocean and you'll notice one thing pretty quickly: the sea tends to break down and overgrow most wrecks very handily due to rust and corrosion rendering the metals and components into their base minerals. A sonobuoy has likely the mineral content of a decent sized motorcycle, meaning it'll barely house some isopods, much less be any sort of reef. Life underwater simply doesn't give two fucks about your opinion or mine.
Yes basically what it does it's meant for submarines who are submerged to contact their chain of command while still being deep in the ocean @Lunar_Capital
Amazing that all that hardware automatically deploys and does so reliably after hitting the surface at over 100 knots. What's not shown is that after a pre-programmed period, the sonobuoy automatically scuttles itself so that it sinks to the ocean floor to avoid detection and polluting the ocean. Since WWII the West has made something like 9 MM sonobuoys, and the US Navy still buys 50,000 to 70,000 per year. Due to high volume production, unit costs are very low (many less than $1K!).
I picked this up from a web page about sonobuoys. Probably was filmed as part of a test. There are many types of sonobuoys, and this one happens to deploy a hydrophone array. You'll also notice from the time marks that this single sequence was spliced from clips taken at different times.
Interesting that the 'umbrella' deploys and probably acts as something of a sea anchor AND makes for a directional to the current fixed unit allowing some amount of directional fixing. Several Sonobuoys would be what you'd drop to get a more precise fix of both depth and bearing. I had always presumed a more simple single hydrophone with several units generating bearing information from triangulation. This looks more sophisticated and I'm sure the details of what the operators get/see/process is highly classified.
Here after the Titan Submersible went missing and banging sounds were picked up by these buoys. What interesting technology this is. I hope they find the lost sub and all of the souls on board return to land!
Update, they found debris from the submarine. Also, the US Navy has finished processing data it picked up from the sonobuoys and turns out there was an implosion sound around the same time the sub lost communications. It's a small mercy that those onboard passed away so quickly they wouldn't even have realized anything. The alternative is terrifying to think about.
I remember seeing about 50 of these in a small compartment of both the USS Shoup and Momsen when I worked on them back in 2009 for a refit. They had Kevlar lines attached to them so they could be deployed behind the ship and recovered later. I don't think they were the same type as in this video though, I don't believe they were a deployable array. Cool stuff though, great idea.
Flew with VP-50 for a year and P-3's are awesome. If you have a great crew, they can hear a porpoise fart at 50 fathoms. First time out, we shut down an engine to increase time on station. Got used to it.
This buoy is either a SSQ-801E BARRA or ADAR sonoboy which is a beamforming capable sonobuoy (hence the 5 arms of sensors). They do not operate at the frequencies of the pingers. The P-3s instead will be dropping special extended operating range SSQ-53F sonobuoys that are capable of acoustically detecting the signal, but without bearing calculation.
EEVblog Cool, must be an ADAR then (I wasn't sure if the ADAR was a recent sonobuoy as the video looksrather old). It also doesn't look like the BARRA we use either, they don't have the interconnecting cables between the elements; just rigid telescopic rods. Also good work on those BARRAs. The ones we use are 14 years old and most still kick along ok when they hit the water!
So that's what a deployed sonobuoy looks like! I always wondered how they could get so much out of so small a can. That's no buoy, that's a miniature survey vessel in a can, as sophisticated as any satellite you care to name!
I grew up under the Moffett Field NAS downwind approach pattern for runway 32 left. To this day, the P3 Orion is the only aircraft I can identify by sound.
This video is next level, way more exciting than I expected. Did not know they were that complex. Whoever decided to edit all those clips together deserves some type of award.
I built p3c orions at lockheed in the 80s main cabin door and left rear lap and mutch more great ship best project i worked on at lockheed NAVY good folks to work for
@@judyburns1912 No ma’am….I’m sorry, I don’t believe so. By the late 80s, I was at sea as a “ship driver”. If he / she is related somehow, I most certainly wish you luck. Please have a relaxing Friday evening.
I work with someone who was part of the group responsible for shooting this video. He was part of the development team for the ADAR. He was very surprised to see it in the public domain!
Hey Jamie! Does your friend happen to have higher quality footage of this? I'm working on a small documentary about whale sounds and scientists use sonobuoys to listen for whales now that they've mostly been discontinued for naval use. We are just looking for some archival footage that shows sonobuoys. Any leads would be amazing!
I don't have access to any, but you could look for a book called "the ears of asw" and contact the authors. I know one of them and he might have some footage.
This totally amazing. I had never seen a sonobuoy operate, this is scary. It’s like a menacing jellyfish you can’t hide from…screw being in a sub, nothing is quiet enough…
I’ve seen a few comments saying this is a low frequency communication array but I’m pretty positive this is the AN/SSQ-101B ADAR Sonobuoy. Crazy to know these are built right around the corner from me in an area you would never think. 😂
Yes on both counts......if they are close enough to where the buoy hit the water, and if they are close enough to the surface when the plane flies over their position.
My kiddo flies on the P3 (now P8). She's getting out in 6 months and is starting to look for civilian jobs. Anybody know any good forums for former P3 jobseekers?
I was an airframer for HSL-42 about 20 years ago and even then we realized how much plastic we were dumping in the ocean. I wonder if sonobuoys are still a thing today.
As Air Cadet in the early 80 i got a jolly on a Nimrod Anti sub patrol Aircraft out of RAF Kinloss we were out for about 8 hours i got to launch one of the sonar buoys out the A/C , i acted as an extra pair of eyes with Binos , we over flew the Russian guided Missile cruiser Kirov and listened in to the conversation between the A/C captain and the cruisers radio operator who was a bit miffed that a muckle great Highly armed anti sub hunter was flying over at about 100 ft , as i 16 year old i was shitting myself but according to the crew its a daily occurrence
I have no firsthand knowledge, but I’ve known some people who served on submarines. I’ve been told that the pings from the main sonar array can kill a diver in the water nearby. I don’t believe these buoys can deliver as much energy as the main sonar of a sub. On the other hand I once stuck my finger in front of one of those little decorative ultrasonic fog generators. It felt like my finger had been hit by a hammer.
@@NoahSpurrier from what i´ve red, that this buoy is only for listening an doesnt ping. Thanks for checking out if these things hurt :D always wondered that too but my brain was telling me not to do it.
Walking on the "GIUK gap." What is meant is that there are so many buoys that have been dropped between those islands in what is a North Atlantic choke point of Soviet submarines, you could walk across that area on them. Its a joke based on operational knowledge. 2000+ hrs PPC P-3C
I can see why the British MOD wanted to retain their Nimrods so much. large inner wing mounted jets - no thrumming to give the game away. Our politicians would have us wearing bright red tunics and playing bloody brass band music.
There are multiple microphones on the different "arms" of that "antenna". By deploying them in a known pattern, they can compare the time the sound reaches each microphone, and use that difference in time to determine the direction the sound came from. If it was just a single microphone dangled down into the sea, they'd only be able to tell how far the sonar contact was from the sonobuoy. By having that "antenna", they get both range, distance, and potentially also depth.
@@heatshield I assume you are making the analogy that by using an interferometry array to measure the difference in arrival time of sound from a single point source to multiple sensors, you are doing the same thing as a GPS receiver, but in reverse (IE, a GPS receiver uses a single point receiver to receive and compare the arrival time of signals from multiple locations). ...But if you are claiming that the underwater "antenna" is a GPS antenna, that is ludicrous; GPS signals are extremely low signal strength and have absolutely ZERO chance of being receivable under any significant depth of water.
@@bronco5334 very well stated and probed. I was indeed simply making an upside-down mental image of GPS using this small array as satellites in the analogy.
