regarding Sejong, Long story short, something about the design's specifications have always seemed off to me, and finding the original Flight III Burke study cemented those doubts. The 128-cell Burke study ballparked the design's standard displacement at 8957 tons. That concept was 550ft long overall, which is 5.5ft more than KDX-III, and the flush deck definitely adds to its volume (and thus displacement), but it's also 10.25ft narrower than KDX-III. Given the ship should be larger than the 128-cell Burke (the wider hull will mean more deck area and hull volume), Sejong the Great should not be some 1307 tons lighter than the former if all else about the designs were the same. Which, of course, leads to the conclusion that all else between KDX-III and the 128-cell Burke is not the same. KDX-III uses the same radar, propulsion plant, most of the same weapons (Sejong has more), and has the same aviation facilities as the 128-cell Burke, so those are mostly out. Technological advances from 1989 to the late 2000s would cause savings in weight for these systems, yes, but with these key items all being the same or better on Sejong that the Burke study, it’s likely this was leveraged to make the former more capable rather than lighter. The displacement gap is not likely down to consumables (fuel, food, ammo, etc.) capacity either, as comparing the loaded displacements yields a fairly similar 1293 ton difference. The Korean ship does have a much lower complement of 300 vs. 363 (the study says 393, but that includes a growth margin), but I've never known accommodations 63 people to cost that much additional weight. If anything, trends of automation tend to show the opposite: a higher level of automation adds weight but saves space, while more crew requires greater space but reduces weight (at least until the larger crew necessitates additional shared facilities like bathrooms and mess halls). All that process of elimination really leaves only one candidate the Koreans are possibly cutting corners on: survivability. Redundant systems, watertight bulkheads, systems separation, shock isolation measures, and deliberately-inefficient system design to minimize single points of failure (among other measures) all add weight. Applied across the length of a 510ft ship, that becomes a lot of extra weight compared to civilian construction standards. Still, quantifying how much worse 1300 tons’ less of subdivision is for Sejong the Great's survivability is can't be done without a detailed set of blueprints. TL;DR The Koreans are likely skimping on survivability, which is why they can shove so many weapons on KDX-III for relatively low displacement. Building a Sejong the Great equivalent ship to USN standards would result in a large, 4-figure displacement increase over Arleigh Burke, likely to about 12000-13000 tons loaded.

For those that think that Koreans are no good at building warships on my opinion they are a better and reliable than the Chinese. Korean Hyundai heavy industry made the two Multi mission frigates a Jose Rizal Class Frigates of the Philippines. It is such a good Warships that even Chinese don't dare anymore to come near to the EEZ of the Philippines after the arrival of two frigates that is named BRO Jose Rizal and BRP Antonio Luna. Hyundai of South Korea are also building the two new Corvettes for the PHILIPPINES that is heavier longer and bigger than the frigates. What I like about Koreans is they always know what is their costumer wants the Koreans able to adjust depends what their costumer needs. Just because it's Asia doesn't mean it's not made with quality. PHILIPPINES is buying warship in Korea the thing is Korean Warships are cheap yet very reliable..

Thanks for video about my country's ship Ship-launched variant of Hyunmoo-3 missile is called Haesung(which means sea-star)-2. Also ROK Navy has AW159 ASW helicopters too. Though they are for frigates, Sejong class can still operate them when it is needed Since Sejong class are KDX-3 Batch-1, KDX-3 Batch-2 will soon be developed, and I expected that they will be one of the best Aegis destroyer in the world

It would be amazing for the US to repeal the Jones Act and purchase 30-50 of these ships. That would get the price even lower, and likely spurs South Korea into purchasing more of them as well, which boosts the US' overall efforts in the Pacific and East Asia in particular.

To Be Honest, this ship is so good looking, not only that it looks sleek but its also sexy👌♥️

This ship is literally at least 3 times as potent as a British type 45 while costing less. It really shows the ripoff of the British tax payer and betrayal of British defence needs. This has 128 vlc, a type 45 has 48. This has a towed sonar and the type 45 being an air defence destroyer as we're told has none. With over twice the vlc air defence and cruise missile capacity and anti submarine sonar and rockets it is at least 3 times as potent.

Canada, AUS and UK should have bought a bunch of these.

brooo this ship is in my fav game modern warship

Great missile shields for US vessels against Chinese missiles!

Burke class destroyer definitely inspires a number of navy to build their own aegis Destroyer!

It'd be unsurprising that Sejong's increased weight was fueled by the desire to surpass the weights of Japan's Kongou & Atago classes which were in service that time...

If you wonder how the hell South Korea built this warship that is no less sophisticated than the latest Arleigh Burke-class destroyers yet more heavily armed and bigger in size and yet... cost less than $1 billion, and they only built 3, as we know for so long that weapons program becomes more expensive if economy of scale not put into use. And now the question is how the hell latest Arleigh Burke-class destroyers cost $1,85 billion per ship to make...? The answer would be $1,35 billion of it alone is pure profit for defense companies and the rest is the real cost to build it.

Could you also do a vid about the brand new JS Maya class destroyers from Japan?

Looks like an Arleigh Burke class

It is a must have warship for the Philippine Navy,,Philippine Defense Department must acquire this kind of warship, it would be a great addition to the defense capability of the Philippine Navy.

This ship is my dream ship in modern warships

Sejong the Great class destroyer Is not a destroyer it’s a cruiser. Destroyer types in certain countries like USA, Korea, China and to a point Japan are cruises not destroyers. Its becoming a problem where it’s losing it intended purpose of being a screening ships for capital ships and turning into something else. The littoral ships didn’t turn out well. They were a cross between corvette and frigate why don’t navies learn. Same for frigates navies are getting confused on intended purpose of the difference between frigate and destroyer. Destroyers are a screening ship and frigates are a anti sub multi purpose vessel.

Make a video about Vishakapatnam class destroyers 🇮🇳

remember, this ship was made cheaper due to thea fact that the shipbuilder in korea applied new technique to build the ship in a more efficient make. South Korea is the best ship maker in the world

This is the best battle ship in the world.

Can it support the impact of an oil carrier (as the arleigh Burk!, "accident" tested), aerligh Burk was in the size of those ships that survived nuclear attack test by the US Navy

It's been a while since I watch this much good content in military category. Good Job!

WOW. NICE VESSEL.

좋은영상 올려주셔서 감사합니다. 모든 분들에게 행운이.....

Your videos are very good, but if you put them in Turkish subtitles, it could be much better.

Make video on vishakhapattanam class destroyer 🇮🇳India's biggest stealth destroyer

I recomend we must have 3 units of this sophsticated warship for external defense. Protection of small warship

세종대왕함이 최고의 이지스함인데, 생긴게, 쌈 잘하게 생겼잖아... The comments were erased by Google kids.

I like this video because its interestyng

This is the possible future destroyer warship in the Philippines in horizon 3, now we have 2 new frigate, 2 new corvette and in Horizon 3, we need at least 2 new destroyer Sejong type destroyer warship.

I hope by 2032, Philippine navy has 3 units of this kind of destroyer. 8 improve daegu type class frigate and 10- 12 HDC 3200 Corvette. THE JOSE RIZAL CLASS BE DOWNGRADED AND RE- CLASSIFY AS CORVETE TO COMPLIMENT TO THE HDC 3200 CORVETTE. THE PN SHOULD ORDER LIKE DAEGU CLASS FRIGATE BUT BE IMPROVE TO 4,000 TONS.

Our deepest respect to both South Korea, and North Korea. Hoping for peace and prosperity for both.

Probably better than the Chinese rust-buckets.

Will these ships carry essm? Plus will they carry the abm version of the standard missile like the more recent burkes do?

Bet ko to for Philippines

这年头 韩吹是真的不多见 大家且珍惜吧

Philippines can afford that destroyer but it depends on our government if they want to acquire destroyers ..

I may think it's a great Destroyer, but the Japanese, the Chinese and the Russians might disagree with it being "the best".

lol the strongest is not type 055 as it’s classified as a cruiser instead of a destroyer😂

Dear Sir and Madame. I am a germ ret navy officer. I know many poor Men from Thailand, that would love to work in your lovly country ! If anybody knows an employer or a job please please let me know. I can garanty their integrity. Thank you very much

Seria un destructor y una mejor opción para Perú el almirante Miguel Grau.🇵🇪

Try to make video on type 058 Chinese zumwalt

You missed the 4x4 box launchers

What 😳😳😳😳😳😳😳😳in MODERNWARSHIP there is also what the hell bro 😳😳😳😳😳😳😳😳😳😳🗿🙏🏽

If the South Korean Navy and the Japanese Navy fight, Japan will lose because Japan will have higher performance and occupancy and the number of ships held by Japan is more overwhelming.

Indonesia can buy this, rokn allow indo buy this destroyer

That is a lot of missiles. It could be argued to be an eggs in one basket situation.

Hey make a video on INS Visakhapatnam please.

Daftar kapal perusak terbaik di Asia Sejong the great class (Korea) 055/renhai class (China) Maya class (Jepang) 052D class/luyang lll class (China) Kolkata class (India) Atago class (Jepang) Lanjutkan 👇

Basically its a Korean version of a Arleigh burke class?

Proved $925M cruiser or Ahead of its time $1B+ Frigate? Which one is better?

*laughs in anything Japanese AEGIS and Frigates

Railgun battleships powered by fusion reactors are the future

Wich one better? This one or Js Ashigara?

Indian Visky class is the most powerful ship in Asia

Dapat may isang distro yer lang sa Pilipinas

If $923million convert to Philippine peso is cost 47.8 billion pesos per unit

Too much eggs in 1 basket... But good as prestige ships. Hopefully it won't get attacked like what happened to USS Mason. Just 1 error, & even that will be crippled by a single cheap cruise missile

They need to build a cruiser.

Woah woah I respect this ship but I wouldn't say this was the "best". A bit too extreme

Where is maya class destroyer ?

it just looks like a copy of an alreigh burke class

Is the goalkeeper a human?😁

There has never been a better time than now for a country to ignore and violate any and all treaties and agreements with the US.

Type 055 said hi

Not a foreign jerk, but domestic one where others and myself must stop video to lookup, to compare other ships, how long in feet 169 meters is. Just so creator can feel smug at his audience insuring fewer future views.

Yo8 forgot 16 harpoons

an outdated sea mine sank south korean ships in one hit..

Bro i live on Kauai!!

join the Arleigh Burke hull design bandwagon

This is only popular because of Modern Warships.

its free market, export economy permits SK affording hi tech arms. An economic lesson the North Korean ideology dismissed.

If something is korean that means it's usa technology

Yo siempre pense que una de las marinas mas poderosas del mundo era la de Japon

Qua manh tau tac trien lien luc dia moi vung nuoc xa bo:

055 says hi😉

Antti ballistic defense interceptor......missille

失踪大王号吗？

It's a good destroyer i play with it in MODERN WARSHIP MOBILE GAME😅

how about 055type？

何でも詰め込んだコンビニ艦でした‼️船はバランスが大事のイメージ覆す結果に‼️

Surely one top in Asia, how dare compare with paper spec one..

someday philippine navy have like this most fightr ship...

however this ship's anti air is pooooor, but it has lots of missile slots and torpedo launcher which makes it strong

Maya, 055: Am I a joke to you?

It’s a fantastic ship though it definitely falls short of the Type 055’s overall capabilities.

It is just scrap, because it has the technology of the Arleigh Burke class destroyer, the destroyer that was hacked and rendered useless by Russian fighter planes from the Soviet era, that is, it is only a destroyer that cannot be compared with its competitors, in addition to this technology supposedly classified American is just selling smoke, because the rival navies already know it very well, this explains why it was hacked and rendered useless by obsolete Russian electronic warfare planes, I don't even want to think what their most advanced fighters would do, in short it's just False advertising of Lockheed Martin, to generate more sales to foolish countries. With respect to South Korea, it is not really a naval power, since it does not manufacture its own propulsion technologies, but it is technology borrowed from other countries such as the United States through General Electric and the United Kingdom through Rolls-Royce, this It allows these countries to control the economy and military production of South Korea in case of military and political disagreements, creating geopolitical dependency, this about the best destroyer in Asia is just sensational news and Fake News.

It even bested the latest Arleigh Burke

this is the baddest warship on the planet - if we're talking youngest...surface combatant. the baddest oldest warship has to be the Kirov. and, if we're going ancient-baddest, it would be HMS Victory. if baddest means WWII baddest, still floating, the American battleship...USS Missouri...i don't even know if it's still floating. the baddest warship of all time? - Yamato or Musashi. not the Bismarck. Scharnhorst was pretty bad. the Hood was just plain bad. the biggest warship of all time? - American Super-carriers. most lethal warship? - nuclear submarines attack and/or ballistic.

Dapat 4 na destroyer na arliegh. 2 otago puede na malakas na yan plus 30 to 35 corvette OK malas na yan navy Hindi na tinag at matibag

👍😎🍺🍩🚢

A nice copy of a Burke

The Sejong the Great Class lost sight of North Korea's ballistic missiles tracked by the U.S. military and the Self-Defense Forces. It is a defective ship without a data link system.

how does it compare to the Type 055
