This is the kind of poor quality gobbling group you get when you don’t have the text check by human

Hedgehog was a spigot morta developed by the Royal Navy prior to the us entering WW2.

With a proper commentary this could have been an interesting video. But the bloody awful computer voice over switched me off after struggling with it for ten minutes.

This was painful to endure. Both the text and audio were poorly done. It's surprising anyone would post a video that a child could have easily corrected.

I, too, am getting fed up with the damned AI voiceovers!! Stop using it and do the talking yourself or get a friend to do it or even pay someone. Just scrap the use of computer speak!

Your computer is having a hard time pronouncing military nomenclature.

The Hedgehog was developed by the Royal Navy for use in the Atlantic against the German U Boats

Toyoda, not Toyota

yes, the number of mispronounced and misspelled terms and mind boggling poor English takes away from the story.

Mk. 10 is mark ten, not make ten. Work on your AI.

The Hedgehog was British

RFE: Allow us the *_option_*_ of captions._ As done here, just detracts from the production. sorry ...

Computer geberated narration is pretty nuch useless when it comes to military jargon. It could be worse, but, not much. Try having some pride in your work someday.

Terribly bad narration and even worse AI translation to text. I do not think I have seen worse. Never the less, it was a good story that will not be getting a thumbs up it deserved.

Lt.C is Lieutenant Commander, not Lieutenant Colonel. Colonel is an Army, or Marine rank, and would NOT be in command of a warship!

Your audience knows something about the subject. It is painful to listen and read the text.

Wasn't the hedgehog a British invention ??

The Japanese submarine fleet never had much chance of success. By mid 1943 the allies had anti-submarine warfare down to a science. The hard lessons learned during the Battle of the Atlantic against the very capable German u-boats of the kriegsmarine. The weapons and detection gear was so highly developed it was relatively easy to find, fix, and destroy any submarine threat

I think you mean the British invented hedgehog launcher. Technology that was generously provided to the US after they entered the war.

Invented by the Royal Navy...

I made it almost 3 minutes before I realized that this was never going to be a video. This is terrible.

The British stunned Japan with the Hedgehog, not the Americans.

It was the United States who used that British invention. Not the whole Continent.

Does anybody know what they are talking about or just take reports and put them through a synthesizer? The Submarines are RO-106 not rot ROW-106.If you monitored and made sure your punctuation was correctly applied it would be accurately spoken. I have been reading such reports for forty years and you make readable reports confusing and at times unrecognizable.

low calibre stuff, sadly. poorly done in a few ways.

Hedgehog was a British weapon ,Asdic was a British weapon, the “ Hunter / Killer groups and tactics used to to hunt subs was largely British…… but hey ….no mention here .👍

"Make 10" should be "Mark 10". Lousy take on an interesting story.

In spite of the typos and audio glitches, this video did tell a compelling story. I knew that the hedgehog was a British invention, but I didn't know that the U.S. used them on our destroyers. Anchors aweigh!

Up and down movements have no effect on contact fused hedgehogs they confuse depth charges which are fitted with hydrostatic pistols which activate at a given depth

Already invented and used by the Brits. We were in this war not only too but did it alone for a long time. Plus who was the only country whose war debt wasn’t mitigated …guess?

British invention yes🇬🇧

Siri, tell me about the make 10 hedgehog...

You needed to proof read (proof listen?) this first. The AI pronouncing DE as "D", Row class? There's more but I stopped watching. There's a video featuring Jon Parshall. Bye.

Ah, yes. The British invented, designed and produced Hedgehog ASW launcher system. _That_ USN weapon.

The hedgehog depth charge was a British invention. It was developed to combat the German Uboats

This is a horrible story. Men doing their jobs and dieing horrible deaths. This is a heart breaking story.

Ditch the AI please. WW2 in the Pacific was a slug fest right up until the atomic bombs where dropped. The one thing that turned that war around was intelligence in the breaking of JN25 and a lot of luck during the battle of Midway.

It's hard to say whether this is voice-to-text, or text-to-voice, because there are so many mistakes in both. And this isn't a "video". There is only one still photo in the entire file. This is basically a badly done audio book. I just don't understand why these are done with computer voices. Is it that hard to find someone who can read text and speak clearly?

I am in awe of the dreadful quality of this soundtrack. It must be a world record performance.

How come they're not mentioning the reason for the depth charges missing the fact is there's a blind spot KZfaq dropping the death churches the Hedgehog corrected this problem by firing ahead of the ship while the submarine was still in contact this is what made the Hedgehog so deadly

Why would the Japanese notify their enemy? Notify superior about the enemy? I'm switching your grade to thumbs down!

Voiceover is gibberish.

The hedgehog didn't "destroy the Japanese Navy in WW2" -- indeed, the headline writer is both historically and militarily ignorant. The hedgehog was a better weapon than depth charges, but it was strictly an anti-submarine device. It had literally nothing to do with the destruction of the Japanese carrier fleet at Midway (and the loss of many of its experienced pilots), or the eventual later sinking of Japanese battleships.

The unnecessary subtitles spoil this doc. That and the mispronunciations. The narration sucks, the subtitles suck and the script is deficient.

The Hedgehog was a great weapon. It could be fired while the ship had sonar contact and if the weapon missed the ship still had contact with the enemy sub so it could do a second attack!

seriously ? this is like a new benchmark for KZfaq badness.

Just say no to A.I.

Gobbledygook I was able to tolerate it for 15 minutes before giving up.

It's 'Mark 10' not 'Make 10'

If you find a "Speak your weight " machine too exciting this is the video for you.

How to ruin possibly interesting content with a distracting and rubbish commentary. Please take it down and do it properly minus robots.

hedgehog was a British system adopted by the US after it had been fielded by the Royal Navy !!

As a once torpedo and anti submarine (TAS) Royal Navy sonar operator I found this very interesting . Thank you for your input.

Great story, thanks!

Sir Charles Frederick Goodeve OBE FRS[1] (21 February 1904 - 7 April 1980) was a Canadian chemist and pioneer in operations research. During World War II, he was instrumental in developing the "hedgehog" antisubmarine warfare weapon and the degaussing[2] method for protecting ships from naval mines.

Useless narration and subtitles - give this one a miss.

Synthetic speech is awful. Unintelligible, almost insulting.

Tell your computer announcer that it is a Mark 10 Hedgehog not a Make 10. Mk stands for Mark which is how they denoted minor changes in production.

At about 12:03 the narrator started mixing Army ranks with Navy ranks involving chain of command among the DE's.

Your videos are well made. Hire an human to read your script. Would make a good site to a very good or perhaps a great channel.

Weird pronounciations. Maybe rethink the speach reader you choose.

"Mk 22" should be pronounced: "mark twenty-two."

Hedgehog British........simple

Some foreigner got most of this out of a book and copied it with spelling mistakes. Next time do it on your own navy. The England was scrapped shortly after the war. She was damaged in a kamikaze attack and was in the shipyard when the war ended. Considering almost all DEs were being mothballed, it was decided not to spend more money on repairing the England. There wasn't another England until DLG-22 launched in 1962.

Using a computer-generated AI absolutely destroys the story

How did this get any thumbs up? Its too bad because with any effort it could have been interesting. I watched the entire video only bcuz it was like watching a car accident the AI is so horrible

How at 0:50 could they claim that Japanese Battle Group could CRUSH ANY Enemy Advance. Um.....all the US had to do was put together a Massive Carrier Strike force with accompanying Battle Group(s) and the Japanese would have been toast!

By Row,he means RO 107 etc, a class of Japanese sub and the "I" class big subs. D is a slobbering saying of DE.. I served in DE 1014 for 5 years in the Atlantic.

As has been said by others . The hedgehog system was developed by the Royal Navy

We still had them 1970! Allen M. Sumner(DD-692).

Admiral Toyoda!

The script was obviously composed by one person, read out loud by another, then transcribed voice-to-text text by a machine. Despite all that the amazing story saves the presentation.

You lost me :32 seconds in. By May 1944 there was no Japanese fleet that could “crush” the American fleet. Anything you said after that was irrelevant. BTW nice computer generated voice. You seem to have issues pronouncing Mk. 10…

I tried to watch this. But the huge red text that was not even the same words as the narrator was speaking made it too annoying. This is literally the worst video I have seen on the navy in WW2.

This was like listening to a drunk telling what should have been an interesting story, only to be ruined by his drunken word salad.

You lost me at a "Fruit Pack"!

26 year old XO? Damn.

You have a 2nd grader's reading ability, matched by your script writer.

The "make ten Hedgehog ENTICE (???) a marine weapon..." WTF??? What fools produced this "cow-pie" with NO proof reading or text checking? This proves to be laughably incompetent in the first few seconds alone! If the creators of this mess intended it for English speaking viewers, then learning and using English grammar would benefit them greatly as would a human narrator. This truly sucks.

LOL How American! 3 entire Japanese armies were fighting! Those troops and resources would have been protecting those islands. The Royal Navy let the US have a carrier when they had most of there carriers damaged. At Okinawa the Commonwealth fleet had 16 aerocraft carriers attacking oil refineries and air feilds. LEARN HISTORY not Hollywood​@sheldonf

Your forcing large Closed Captions on us when KZfaq provides better ones is obnoxious. 😬 I will avoid your channel.

Keep a tight eye. With such ignorance of their own language, the USA is lost. A tight eye. Tightly closed? Get out of this business. Pathetic.

Only thing wrong with this was the narration... Would have more impact if you didn't have to think about what was said in a few instances...

This seems to have started as a decent script, but errors were introduced when read by a text-to-speech synthesizer, then more errors apparently from generating subtitles off the synthesized speech. Unfortunate results, but a good story if you can ignore all the glitches.

The boredom of the single image is lightened by amusement at the awfullness of the subtitles and commentary. I gave up about a third in.

Unacceptable. Bland slide show. AI voice with all the typical mispronunciations of common words.

I offered a thumbs DOWN for the editing and captions. Too hard to read / follow / understand.

Always thinking of an alternative or response. Could an enemy have constructed a sub (perhaps many) with the intent and purpose of sinking anti submarine type surface craft? This could have been done with quieter, faster when submerged and with torpedoes with a smaller warhead. Just a thought.

This is what happens when your A.I. gets high. Put the bowl down, just say no.

One single picture for a 32 minute video?? Kinda makes a video meaningless.

Submarines don't explode they implode.

The sharks - frightening - were the people alive when the sharks began their feeding frenzy?

Pacific Islands are impossible for computers to pronounce . I wonder how many unexploded hedgehogs lie on the bottom of the ocean.

This must be the worst attempt at an historical video clip that I have ever seen. It, because of the ineptitude of the poster, fails. It fails in whatever it was intended to do. As an afterthought the poster obvious knows nothing about Hedgehog. please take this badly produced video off KZfaq. ps: Do you know that the Destroyer Escorts (US hull classification DE) were lend-lease ships, built by US shipyards to a Royal Navy specification, and very useful they were too.

Destroyers are abbreviated ' DD 567'

The hedgehog weapon was created by the Royal Navy in 1941

What an extremely poor programme. Agree with every comment. Gave up after many mispronunciations and reference to the US hedgehog. Recollect reading sixty plus years ago of the development of this weapon. Initially the bombs would skid on contact withe the surface of the sea until the pointed nose was changed to a flat nose. Then the fuse would detonate the bomb with the hard contact with sea. Next solution was to fit a screw in the nose which would arm the fuse as passed through the water. All done prior to December 1941.

You have a surprising number of mispronunciations of English words and misunderstanding of terms. (Ashkins is wrong - the depth charge weapons were nicknamed Ashcans. And it is Mark xxx not Make. (i.e. Mark 1 or Mark II or 3 indicating improved versions of a specific weapon. It would help if you had a better education to do this narration.

May have been an interesting video if one could see it, get rid of the captions

Very interesting story, but the frustrating AI narration was like a depth charge attack on the continuity of events. My hope is that AI voices improve drastically or are dispensed with entirely.
