- During the Ala ʻAumoana Kai Uli (NA154) expedition, our Corps of Exploration completed a comprehensive survey of Imperial Japanese Navy (IJN) Kaga 加賀, the Japanese aircraft carrier sunk during the Battle of Midway in June 1942. Following dives on other Battle of Midway wrecks (USS Yorktown and IJN Akagi 赤城), the team explored Kaga in its final resting place within Papahānaumokuākea Marine National Monument (PMNM), the largest protected area in the U.S. and one of the largest in the world. The dive was launched and closed with protocol ceremonies to honor this place and all who lost their lives in ways that reflected their significance to Kānaka ʻOiwi (Native Hawaiian), Japanese, and U.S. military families and communities.
These historic noninvasive, visual survey dives were conducted during a 27-day NOAA-funded the E/V Nautilus expedition to explore never-before-seen deep-water habitats to collect baseline data needed to support management in the most remote and northwestern section of Papahānaumokuākea Marine National Monument (PMNM). PMNM is a UNESCO World Heritage site distinguished for both its cultural and natural significance, the only site with this special distinction in the U.S. It is currently being considered for national marine sanctuary designation to safeguard further its diverse natural, cultural, and maritime heritage resources for generations to come. Each dive on Battle of Midway cultural heritage sites was launched and closed with protocol ceremonies to honor this place and all who lost their lives in ways that reflected their significance to Kānaka ʻOiwi (Native Hawaiian), Japanese, and U.S. military families and communities.
The Battle of Midway surveys were made possible by the expertise, support, and collaboration of many partners including Ocean Exploration Trust, NOAA Ocean Exploration, NOAA Ocean Exploration Cooperative Institute, NOAA Office of National Marine Sanctuaries, SEARCH, Inc., U.S. Naval History and Heritage Command, International Midway Memorial Foundation, Papahānaumokuākea Marine National Monument, Office of Hawaiian Affairs, the State of Hawaiʻi, U.S. Fish & Wildlife Service, University of Maryland, University of Rhode Island, University of Hawaiʻi, Bureau of Ocean Energy Management, Defense POW/MIA Accounting Agency, Air/Sea Heritage Foundation, and Japanese archaeological colleagues from Teikyo University, Tokai University, and Tokyo University of Marine Science and Technology.

Kaga was expected to be a devastated wreck by the hanger explosions she suffered, but this is just total destruction. Japanese eyewitnesses state she was almost totally destroyed past the bridge down to the waterline, with only a small portion of the flight deck left at the stern. She suffered greatly.
Kaga seems about as destroyed as a shipwreck can be without suffering a magazine explosion that turned it into shreds. There is a sketch in Parshall & Tully’s Shattered Sword of what Kaga is believed to look like at the time of scuttling. With the exception of having lost the rest of its hangar, the island structure, and maybe 40 feet of the stern (probably in the course of sinking), the sketch is remarkably accurate - and sobering.
In the journal of the vice commander of the Soryu, he stated that when the first explosion went off, he was convinced nobody on the ship could have survived. It must have been enormous.
Hoping they will produce 3D renderings of the Midway wrecks.
I'd love to see this
Oh my god thank you so much. Sailors rarely follow a flag. They protect their machine and fellow shipmates. They follow the orders of their nation. They are not cruel, but actually rather kind to the survivors of the battle. With the deepest of respect I bless all sailors of all nations in this instant. Can't wait to swap stories in heaven.
This was war not Hollywood love drama we’re you expecting something else or still living in the past
I know, but I like to think that honorable men like Sturdee and Von Spee were also in the Pacific war.
I hope many men on both sides served with honor. @@oriontaylor
if they've found Akagi and Kaga, then Soryu shouldn't be too far away, and Hiryu should be north of the three.
Have always followed you guys for the marine biology and scientists' reactions. Amazing that the Nautilus was able to be a part of something so historic & sharing it with us!
Nautilus putting in the work
One thing to point out about the casemate guns from both Kaga and Akagi. They are not actually the original casemates that were planned for either the Amagi-class battlecruiser Akagi or the Tosa-class battleship Kaga. The original plans called for 140 mm or 5.5 inch guns in the casemates and the number and locations they were to be placed were radically different than where the 200 mm or 7.9 inch casemate guns ended up the carrier conversions of both. What they were a holdover from was the surface action oriented thinking of most navies because carriers were such a new idea and no one was entirely sure how best to use them at the time the conversions were planned. Akagi and Kaga even carried twin 200 mm gun turrets of a similar type to the Takao-class heavy cruisers wedged between their flight decks when they were in the original multi-flight deck configurations they were converted to initially, which were removed during the heavy rebuilds they both got in the 30's. There was much thought given to the idea of having carriers operate forward with traditional scouting units and therefore they might need protection against the new heavy cruisers that were expected to part of an enemy scouting unit. The USN did the same thing with the four twin 8 inch gun turrets that were originally on the Lexington-class carrier conversions of the same era, which likewise proved be a waste of tonnage that could be put to better uses.
In the days of early carrier doctrine, navies were unsure of how far apart the fleets would be and guns of this size were considered necessary for emergency defence (while getting away) if a carrier was caught in the open by an enemy scouting force of cruisers or destroyers. Courageous, Glorious and Furious were almost unique in that first group of carrier conversions in not having guns of 6-inch or larger for that purpose.
They ended up removing the 8 inch guns on the Saratoga and replacing them with 5 inch dual purpose guns. They were going to do the same with the Lexington. I think they had removed the 8 Inchers before The Battle of Coral Sea but never got to add the 5 inch guns as she was sunk.
Thank you EVNautilus, NOAA, and others plus pioneering deep-sea explorer Dr. Robert Ballard for this Midway footage.
Utmost respect for those who’ve perished, may they Rest In Peace. Historical sites like Kaga and Akagi shall hopefully teach us to understand, in a brief frozen glimpse of the wreck, the sadness and dynamic nature of this conflict.
19:20 - Looks like one side of a lifeboat support bracket with black rubber pad... Amazing footage. Appreciation and Respect.
Rare and fascinating!! Thrilled to see historic piece being revisited.
It's amazing the damage and terrible the loss of life on all sides . One of the things i find interesting is that all of the IJN Carriers were completely different from each other . The American Carriers pretty much stayed with the same design, except for the light Carriers that came out towards the end of the war . Great videos, thank you
This is so incredible, I had goosebumps watching through the whole thing. Really awesome to see the wreck and what the ocean does to it over time.
Imagine the damage of a already damaged ship takes as it before hits bottom from falling xx mph, miles from the water surface. Imploding of air pockets and structures departing from the force of decent. Enemy or foe, it is all the same. It takes a lot of humans to make a ship fight, most of the crews who passed remains are there today.
Incredible forage. Thank you for sharing this historic moment.
You guys are doing incredible work here.
May the decades to come be kind with Kaga.
Kaga is and will allways be best fox
As a former naval member, I can understand the crews strong desire to complete their tasks. I can also understand the fear as their ship, their home, becomes engulfed in flames. I wonder though, of the engineering crews. Were they able to escape or did they reconcile their fate. War is the most perverse of all mankind’s follies. Fair Winds and Following Seas
On Kaga, it’s believed most of the engineering crew were trapped below, as the hangar above was not just engulfed in flames but was being disintegrated for around ten hours with fires and explosions from avgas and an estimated thirty-six tons of bombs. It would have been a horrific experience for anyone.
Amazing, great work 👏👏👏👏👏
Thanks very much.
素晴らしく貴重な映像をありがとうございます。 今まで赤城とヨークタウンと映像を拝見してきましたが、この空母加賀の映像は分かり辛いですね、壊れた鉄の塊の連続に見えてしまいます。 おおよその全体像をイメージできたらありがたいです。 たいへん図々しいのですが、空母加賀の海底での全体像をイメージできる画像などこしらえていただければもっと素晴らしいのですが、可能ならお願いします。
sorry to ask this dumb question: why is the submersible going up and down all the time?
Ah never mind. 4.33
wonderful stuff!
Thanks❤❤❤ so much❤❤❤
I just want to say Thanks
I hope they will put together a hard back book about the Akagi / Kaga wrecks, like what was done for the Yorktown. I'm also hoping to see an Artist rendition of both wrecks.
Hope they are going to look for Soryu and Hiryu too, anyone know how deep these wrecks are and if they are safe from plundering by salvagers?
3.3 miles deep. They'd have to be some very skilled and well equipped salvagers
Are there somewhere Drawings or 3D animated Pics where i can see how Akagi and Kaga now look in a complete overview?
Always cool to see wrecks
💙
Curious, this must be at some depth - why the bobbing motion ?
They are using a direct tether ROV. So instead of it being a secondary, free moving ROV we usually see, this one is directly connected to the surface ship which is moving with the surface waves. I read the other unit had issues so they had to use this one.
I thought at least one or two of the beams that supported the flight deck on the bow and sterns of the Kaga and Akagi would still be standing.
Hopefully no one scraps the metal from this one like some other wrecks in SEA, It's low-radiation steel has become valuable and it's siting in international waters.
Very much doubt it. She and the other wrecks are about 18000 feet down in the middle of the open ocean. The amount of money and equipment it would take is way more than what the metal is worth.
What's the difference between low radiation metal compared to metal produced today?
@@MuhammadAli-255 You said it, the amount of radiation. The detonation of nuclear weapons (during WW2 and in testing afterwards) has released a lot of radioactive fallout into the air. Air is used as part of the process of making steel, and as such contaminates it. This isn't a problem most of the time, but if you're making something like a Geiger counter you want the reading to be as accurate as possible. That's where pre-war steel (especially pre-war steel that has been insulated on the ocean floor as part of a warship wreck) comes in. Many wrecks in the South China and Java Seas have been salvaged as a result, in spite of their statuses as war graves.
The demand for pre-war steel isn't as big as it used to be, though: in 1963 a treaty was signed that banned all nuclear weapons testing except underground. Since then, background atmospheric radiation has almost dropped to pre-war levels.
Очень интересно!!!!
Are there any plans to resume a search for Soryu and Hiryu?
They found 3 carriers out of 5. Why wouldn't they want to complete the collection?
How many sunkin ship's have you found
Doomed by fire and her own ordinance
Doomed by brave American young men who saved the world from itself.

Converted cruiser with guns of zero capacity on an aircraft carrier.
Incorrect. Converted battleship, and those guns were seen as vital for emergency defence if caught by enemy cruisers. It was not just a Japanese school of thought, but interwar exercises by Britain, the U.S., and even the French reinforced that idea.
@@oriontaylor They said those guns could barely elevate. They also said they doubted the Kaga carried ammunition for those guns - on the precept it would never find a scenario where they were required to fire them.
The vessel - converted to a CV - was not going to find itself in a naval shootout.
Get proper equipment. This bobbyhead up and down swing is unwatchable.
The Kaga was hit with two 500 pd bombs fom dauntless from the Enterprise and a 1000 pd bomb
