Japanese Submarine Crews Intercepted U.S. Sonar Buoys — Then Realized The Ocean Was No Longer Theirs
Video Overview & Insights
Discover how Japanese submarine crews intercepted U.S. sonar buoys in WWII and realized the Pacific Ocean was no longer theirs. This untold story reveals the shocking technological superiority that doomed Japan's submarine force during World War 2. From the dramatic sinking of I-52 by acoustic torpedoes and sonobuoys in June 1944, to the bold Operation Barney mission where nine American submarines penetrated Japan's "safe haven" Sea of Japan using revolutionary FM sonar in 1945, witness the systematic destruction of Japanese naval confidence. Learn how American anti-submarine warfare technology – including radar, sonobuoys, acoustic homing torpedoes, and mine-detecting sonar – created an invisible surveillance grid across the Pacific that Japanese submariners couldn't escape. Explore the fate of Japan's massive I-400 submarine aircraft carriers, the largest submarines in WWII, and discover why American submarines sank 1,314 Japanese ships (5.3 million tons) while Japanese subs managed only 184 Allied vessels. This historical documentary examines primary sources, survivor testimonies, and declassified records to reveal how technological warfare transformed the Pacific Theater and why the ocean belonged to those who controlled the technology. Perfect for history enthusiasts, military history buffs, naval warfare fans, and anyone interested in WWII Pacific War stories, submarine warfare tactics, and the role of technology in determining victory.

The same sentence is restated throughout this video. Technologically doomed Japanese submarines were overpowered by US industry. Over and over.
@billmcdonald9115I flew with Ltcdr aaron d levitsky out if Lakehurst! He had flown I n the Battle of Midway against Admiral Chichie Nagumo who was responsible 5:55 🎉 for Pearl Harbor !Sonabuoys were part of our sub hunting procedures and all mentioned in my new book "60 Gates" coming soon!
@stephensafka8595The FM sonar story is told from beginning to end in Adm. Lockwood's book, Sink em All. Some brave civilians took some hairy rides in those subs to get the tech to work.
@billybupkis3688The audio wire recording of the fatal U.S. attack on I-52 can be heard on the YouTube video "The incredible Sinking of Japanese Submarine I-52 during WWII - A Case Study", https://www.youtube.com/watch?v=xvMKEko90GU. Official documents describing the attack are also shown and discussed.
@woonsocket686Nice to hear my Portsmouth, NH was helpful to the war
@pete6705If we could do this in world war two , then it's no surprise we can find drug boats on the ocean today. The only question is , why don't we SINK all those drug boats?
@CAROLDDISCOVER-2026"The transformation was Complete - jap(a)nese submariners became Not just American Bi+ Chess, but Eagerly Cooperative Bi+ Chess, absorbing every little issuing detail in detail, internalizing the causes of their failures ...."
@Joe-ef2nrMy uncle, Harold F Willard Seamen first class, was a sailor in the silent service during World War ii. In fact on December 7th 1941, at 8:00 in the morning he was up on diamond head with a buddy enjoying the view when they saw the entire Japanese attack come in. He said they said a record for hauling ass coming down Diamond Head and when they got to the bottom the military police and civilian police were telling everybody to get back in their homes and all the roads were closed. He couldn't get back to his boat until the evening and he said he was absolutely stunned by the devastation that he saw and the friends that he had lost. I don't know the name of the boat my uncle was on, but I know that he was on several war patrols and that they had been depth charged on occasion. He had bad hearing and was very claustrophobic being 6 ft 2! My uncle Harold was my favorite uncle, he was a hell of a guy with a great sense of humor! Rest in peace Uncle harold, you did your job and you did it well!
@Jakal-pw8yqThe thumbnail is the Gibraltar. Wrong ocean.
@BobK58I served in the US Navy from 72-78. After A and C schools with Submarine Squadron 16. Never heard that we had this technology back in 1944.
@GeoHvlGiving the Russians the big middle finger, even back then. George Patton was also right.
@GeoHvlI think that Yamamoto warned them. The American industrial might is awesome… not so sure he said it like that but his quote was close.
@GeoHvlThe ocean has no mercy, and sonar made it even deadlier.
@TrueCrimeChronicles02These videos would be much . . . MUCH . . . better if the narrator was not in love with hearing himself constantly repeat everything a half dozen times. State the message of the video . . . show the parts that make it up . . . show how it worked and get off the air. This video could easily have been done in 15 minutes . . . maybe even a bunch less.
@dwightcimino1040There is a feller that does electronics on YT that has a wire with something recorded on it from way back when like shown @19:00
@JackAsstorWOULD YOU PRONOUNCE SONAR CORRECTLY? OMG!
@steveelsholz5297When a site like this one treats me like prey or something to be trapped and deceived and listening to all of their advertisements I counted as extreme disrespect. I will not stay and listen to your multitude of advertisements just to earn you another Buck for nothing.
@SEKOTDI detest listening to a psychic crowds all of its ads into the last half have a podcast. Recite managers believe they have been trapped the listeners to hear all of the advertisements in order to finish the listening begun. But it doesn't work because I have learned to bite the bullet and leave a site that inundates me with advertisements after a hunger and a lust for exorbitant profits. I listen to this site at 2:33 minutes and when as got to every 3 minutes I left. I would encourage other listeners to do the same and encourage these site managers to quit performing this despicable practice. When they learn a respect for their listeners they will begin to understand they cannot treat them like a source of mere income.
@SEKOTDThank you.
@WW2Insights-s6uObvious question... What were Japanese naval vessels doing patrolling the Atlantic off the west coast of Africa?
@edwardhegarty750Navy here
@WW2uncovered-b2hI truly honor and respect the soldiers of the Japanese empire, but they were arrogant.
@patrickmullane30God help submariners everywhere ✝️
@patrickmullane30The Japanese overcame 500 years of technological advances in one hundred years to become challenging to the west.that is still magnificent though obviously hubris.
@patrickmullane30Remember, Japan one hundred years prior was still medieval
@patrickmullane30Too much 🤖🤖
@sylvainesteve5222RIP to all lost during this war.
@ts.elliot5870I don't care what the narrator of this video says ... America's superior technology allowed them to defeat Japan's inferior technology .... This video is NOT going to change my mind about that.
@donofon1014This series on US tech and mfg advantages brings home current complaints from smaller countries about US dominance. Had Germany and Japan NOT gone to war, would the inward looking US be where it is today? IDK.
@mbranagan4277Not mentioned: US submarine operating conditions were wildly better than Japanese units. Food, ventilation, sanitation, medical care, etc., differences meant US sailors could be more effective on longer patrols.
@jimmiller5600Fun Fact --- Japan lost a major logistics link before December 7th, 1941. Pre-European war, Norway was a major contributor to global ship transport. With the German invasion of Norway that fleet fled Axis territory.

@ArchiveHystoryWW2Got chills watching this!
@kmoldphotosWhat starts as a excellent and very informative video sadly after 20 minutes is like listening to a parrot repeating itself 😢...
over and over almost the same text and information is repeated and this way a 15 minute video is stretched into a 45 minute long video 😭....
Ww2 us bombers has some excellent coverage of the sonar buoy
@markworden9169Very Interesting story ❤
@KhanKhan-c4y6uThe Channel WWII US Bombers has a good video on this attack.
@tgamronThe IJN submarine sunk by Operation Barney was I122, a mid-1920s boat that had been relegated to training duty.
@petestorz172Japan and Germany liked to build things as close as possible to Engineering Perfection. The submarines were a good example of that. The United States liked to build things that were good enough, in obscene quantities. The American approach to the tools of war was the epitome of "Sometimes, quantity is a quality all its own"
@Neon217interesting to watch
@Thewarlog1075The Japanese were impressed with the Statistical Process control systems developed by the American W Edwards Deming. And then the American MBA’s decided it was too expensive to keep using. And they didn’t need to, since in the 50’s the US pretty much had a monopoly on manufacturing. Everyone else was rebuilding. And so it goes.
@professortill8592amazing video
@BattleHistoryHubTime 36, the acoustic homing torpedoes did not get anything from a sonobuoy. They did it all on their own.
@mel-m2sTime 13, is that the sonobuoys?
@mel-m2sThat moment of realization for Japanese crews must have been terrifying – the ocean, once their domain, suddenly a surveillance grid. A powerful look at the psychological toll of technological asymmetry in WW2.
Great work on the research!
17:50 - Ah, wire recorders. I got to see one in action when I was a kid. It worked like a reel-to-reel tape deck, but with small spools of wire instead of reels of oxide-coated tape. I remember the audio quality being pretty bad.
@ztoob8898Too long, becoming boring.. get on with it,please
@kennethmaney914Absolutely in love with this story
@GeschichteUrsprüngeThe Japanese submariners should have been glad that the filthy Commie swill did not get to study their best submarines!
