Korea will build a 30,000-ton light aircraft carrier capable of housing more than a dozen F-35B vertical takeoff-and-landing stealth fighter jets.

A government source on Monday said Joint Chiefs of Staff Chairman Gen. Park Han-ki and the chiefs of the Army, Air Force, Navy and Marine Corps in a meeting on July 12 decided to push for the project.

The carrier will be the Navy's biggest ship, nearly 1.5 times as large as the Dokdo or Marado landing platform helicopter ships.

It will be designed to accommodate 16 F-35B VTOL stealth jets, 3,000 marines, and 20 armored landing craft.

It will be about 250 m long, a little longer than Japan's Izumo-class helicopter carriers. Japan plans to turn two Izumo-class helicopter carriers into light aircraft carriers capable of accommodating about a dozen F-35B stealth jets by 2023.

Hmm, advanced in the sense they took a cutter to an old Romeo and inserted a couple of missile tubes. An SSB of late 1950s style...

The South Korean 'carrier' sounds more like an LHA/LHD platform than a full-blown dedicated carrier.

Any information on the powerplant, is it an combination of diesel and gas turbine (MT30) the same as the QE's?

Given it is most likely to be based on the Dokdo-class amphibious assault ship, I would expect the propulsion to be more in line with that. Thus something like four SEMT Pielstick 16 PC2.5 STC marine diesel engines

I am not sure of the size though.

I agree it would be a logical choice, given the design origin, though it would be interesting to see which diesels they go for, if indeed that is the way they go.
The articles state this will be bigger than the Dokdo, and I have seen it said in some places this could be over 30 000t.

The Dokdo has about 32 000 hp for a displacement of about 19 000t. Speed is about 23 knots.
The San Antonio class LPD of the USN also uses SEMT Pielstick diesels, but pushing out around 40 000hp for a displacement of around 25 000t. Speed is about the same...23 knots.
I'm not completely up to date on SEMT Pielsticks range, but I can't really think of a more powerful 4- engine installation much above 40 000hp?

I reckon if it gets to much over the 30 000t mark, it will get LM2500 gas turbines, which are also used by the Korean navy.

There's some reporting that the LPX-II propulsion plant might be related to KDDX, which is likely to have some gas turbines.


And as of 2019, GE was offering LM2500 for both KDDX and LPX-II, as part of some sort of either hybrid of integrated full electrical propulsion plant.


That said, the images posted most recently show exhaust stacks that are very similar to the Dokdos, which certainly supports the idea that the plant will be all-diesel. They haven't added the large air intakes/exhausts you'd expect for a turbine plant.

Not so sure. Those 4 round exhausts seem pretty big to me, bigger than Dokdo’s diesel exhausts and similar to Cavour’s (4x LM2500).

some reports that the UK was going to help South Korea with their carrier but now SK is denying it.

on a related note, since its an actual carrier, not an LHD.. shouldnt they add a ski jump


The Trieste is actually a LPD/LHD and already has a ski jump....

Unless they're planning to go cats and traps and are trying to keep it quiet?

Not wanting to go off topic, but isn't the Trieste supposed to act as both an LPD/LHD and an aircraft carrier? I've read reports that it's supposed to replace the Giuseppe Garibaldi.

Getting back on topic, does anybody know the dimensions of the South Korean design, or have they not been released yet? My guess is that it's around the same size as the Trieste.

Yes, she wil cover both roles.
Primary LPD/LHD and Aircraft Carrier as spare unit when Cavour isn't available for maintenance reasons.
so sorry for this off topic.
whats the aircraft capacity of cavour vs trieste? is hanger space the same?

okay back to the Korean carrier
it seems they ordered F-35Bs, so I guess cats are out?
if its primarily intended to fly Bs, a ski jump would make sense.

^ thanks! sounds like Trieste is basically Cavour with one extra floor, for the landing dock stuff.

Depends how to define 'carrier technologies'. Ammunition lifts and electrical power systems are not what you would necessarily think of as just applicable to carriers.
It could be a non-denial denial to keep the wraps on the carrier programme, or more likely Daewoo and Hyundai are putting on pressure to develop those items locally.

Yes, exactly what the Italian Navy need as not only Garibaldi's replacement but also to "Santi Class" (San Marco, San Giorgio and San Giusto) small LPDs.
The Italians are planning for 2 new ships (LHD) and an option on a third (LHA) to replace the Santi class. I’ve seen various report of 18,000 ton ships or 21,000/24,000 ton ships

I think you will find the South Korean and UK government's were probably discussing fact finding missions to the QNZL during her far east deployment to gauge F-35B operations from a dedicated STOVL carrier, they will be looking at the technology and the and how it is operated to see how they need to bring their carrier plans into fruition. They will also talk with the US, the Italians and maybe even France as Carrier operators before they finalise their own plans and place orders,
