WOW!! This brought back memories. I started my naval career as an acoustic operator on P-3's back in the mid 70's. Not really covered in the video, the buoys had water initiated inflatable floats that were color coded to the buoy channel so that the pilots could locate them. I'm not sure when these were added, but in the 70's some of the buoys were equipped with sea dye markers and smoke markers to make it easier for the pilots to locate. The buoys were intended to be used in conjunction with MAD, and not as a standalone system. The pilot would fly to the closest buoy and then enter into a MAD hunting circle, dropping smokes on each MAD, generating a visual course of the sub, and then fly down the course dropping a weapon on the next MAD. THANKS FOR THE MEMORIES!

I grew up near Moffett Field and was fixated on airplanes but especially the P-3s, all the more once I learned their mission and the distances they flew each time. To this day my family teases me for running outside many times each day to watch them fly overhead. If you flew out of Moffett I am 100% sure I was looking up at you from my yard numerous times. (I still can't help but go outside when I hear something unfamiliar, only my wife is more understanding - or at least tolerant).

Today with DWARF sonobuoys, it is possible to carry six DWARF sonobuoys in the space occupied by only one full-size buoy.

Very dynamic and alive presentation. I expect during ww2 each individual listening operator had adapted what they learned and improved on their own technique

I never thought I'd be listening to WW2 sonar recordings on a Friday night. Very cool. I didn't know this tech was available back then.

Oh yes, it surely was.

This is an execlent channel. I've learned something from each video. I'm 81, and have studied WW11 for my entire adult life thru books, and thought I had a pretty good grasp of the technology of the day. Thank you for your research.

It's great because he keeps things moving along. If you want to pause a part or rewind then you can.

Good info! The actual training sounds were a great touch! First time I have heard the actual noise that the subs were making.

Another good episode. The WW2 sono-buoys were really little more than prototypes despite 150,000 being produced - probably reflecting their 12th and last place in the development list. A great idea but the technology at that time was not adequate. Sea state 1 was mentioned in the video but that is something that is beyond rare in the Atlantic, North Sea and in UK coastal waters. In reality there was a lot more water noise. Post-war the UK did an analysis of 23 positive U-boat sono-buoy identifications by Coastal Command. This was then matched against BdU records and it was found that in no case was a U-boat any closer than a mile and it some cases the nearest was 200+ miles away. There was a lot of wishful thinking. Great original audio clips.

Which was why we continued to develop sonobouy technology during the Cold War. This was a very interesting video;I didn’t know that this technology was originally introduced during WWII.

Some of the aircraft shown are from RAF Costal Cammand 120 Sqdn. My father John Pat served there, first with Sunderland flying boats then LB30. He was with 120 Sqdn from just after the blitz until early 1943. Dad never told me anything about using sonar.

What an excellent video! So much of your videos cover material that is fresh and in depth, in direct contrast with the thousands of videos that rehash the same tired topics over and over.

You've posted a lot of great content, but I would say this is the best thus far. Well done.

Your series is excellent and very enjoyable. I am hugely impressed with the work you are putting into this. Thank you!

Appreciate details and precision! Please, keep the videos coming!

Wow, much more fascinating than I thought! Who knew that I'd actually be partaking in the quiz at the end from an old 1940's "Sonobuoy sub-locating exercise" haha

The submarine noise in this video was amazing. Where did you find these recordings?

Came here to say exactly the same thing! Incredible to listen to - never heard samples of that before.

Love your series on the anti sub warfare. My father flew P2Vs after the war and often mentioned using sonobuoys in the anti-sub exercises. I got the impression they were very effective. Thanks for your video as I learned a lot of detail. Regards

Thank you - your channel never disappoints!

holy hell a 21 minute video! AWESOME! NOW WE'RE TALKING.

Appreciate the love shown for the U-boat War. Couple of questions: once a submerged U-boat was detected/pinpointed, what method of attack would be used? How many sonobuoys would be generally carried onboard?

@@JohnRodriguesPhotographer Saw it. But, bombers had to be reconfigured to suit this new mission and there must be a lot of things going into this. His level of research is likely to give a better understanding as to why the Liberator was the preferred platform as opposed to the B-17, etc.

Excellent original research, much appreciated !

Awesome as usual, great work!

I've been interested in history since I was a kid, I find this fascinating.

The test at 17:55 to 19:55 seemed pretty simple; maybe I'm a good candidate for ASW crew. Also, I detected a cat meow during the record playing parts.

This is the first time I've heard that sonobouys were developed and used during WWII.

A request for in depth looks into particular bombers and what was done to them to address particular ASW needs. I would love to see a comparison between a stock B-24 and VLR variant of said aircraft.

It was RAF Coastal Command VLR Liberators, only 41 in number, which closed the Atlantic gap and caused Black May. Stripped of guns and armor and equipped with auxiliary fuel tanks in the bomb bay, they were the only planes at the time with the range to patrol the gap. Small numbers of the VLR had been in action since late 1941, but the RAF Bomber Command, Churchill, and the USAAF all opposed their use in "wasteful" defensive maritime patrol when they were needed for war winning offensive strategic bombing campaigns. Only when the U-boats appeared on the verge of victory did the allies finally provide RAF Coastal Command with the plane it needed to win the U-boat war.

Deadly simple. As long as you have a compass you know where it is. Subscribed. Thanks

The reason that the screw noise produces beats even though it turns in smooth continuous circles is that the blade making the cavitation is sometimes turning toward the listening hydrophone and sometimes away from it as the screw turns in its circle. Thus the pitch changes in a sine wave: beats.

I am continually amazed that the belligerents were even able to find each other in the open ocean, let alone accurately place rounds on target, given the rudimentary technology available!

Thank you-very informative.

Adding Ven diagram circles for range would help; smaller circles around the buoy with a strong signal and larger ones around the buoys with a weaker one. then lok for the intersections.

Cool stuff. Didn't know that the tech was that well packaged that early

Sonobuoys have come a looong way since these were produced

Commenting in June 2023... I've been watching this series and didn't know about sonobuoys at all, never mind how they were used to find U-Boats. As I type they are using the modern version of this tool to help find the missing submersible that was diving on the Titanic. Interesting coincidence.

Soooo cool. Thanks!

Fascinating information.

Love the way "buoy" is pronounced boo-ee.

Considering the ambiant noise in an arcraft, what hed set did an operator use as most of the aircrew headsets didn't screen out much noise.

This is the in-depth knowledge military history buffs love! Thank you for the channel!

Guesses to the quiz in the comments? I'm guessing the sub is running SE at high speed, just south of Red. I'd center my next pattern SE of red.

All the WWII History "I Know"? I did Not Know we had Sonobouys this Early! One of my gampas Was In the Battle for the Atlantic Anti Sub!

Verry educational, for someone like me who's just interested in technology

Sonobuoys plus Fido and Hedgehog finished Axis subs.

Is there any data on the submarine countermeasures, the German navy invested a lot in 'bolde' so I was curious if fido or sonar buoys could detect the difference?

How much did these WW II sonobuoys cost?

Having a quiz is very cool.

Why do you call them 'depth bombs' instead of 'depth charges' ?
