South Korean Navy

[Sandhi Yudha]

The Republic of Korea Fleet has three numbered fleets each assigned to the seas east, west, and south of South-Korea. The three numbered fleets are responsible for protecting the coastal water around South Korea: The First Fleet is for the eastern naval sector, the Second Fleet is for the western naval sector and the Third Fleet is for the southern naval sector including Jeju Island.

And now one these three fleets will be replaced by the Maritime Unmanned Forces Command, which will consist of an unmanned surface vehicle flotilla, unmanned underwater vehicle flotilla, and unmanned aerial vehicle flotilla.

ROK Navy Announces Major Reorganization - Naval News

ROK Navy announced last week that it will undergo a major reorganization including establishing a “Maritime Unmanned Forces Command.”

www.navalnews.com

South Korea’s Defense Acquisition Programme Administration (DAPA) signed a contract with Korea Aerospace Industries (KAI) to develop an attack helicopter for the Republic of Korea Marine Corps (RoKMC) based on the KAI MUH-1 Marineon amphibious helicopter.

KAI will make three prototypes of the new version, now dubbed MAH (Marine Attack Helicopter) and will use weapon components developed for the KAI LAH, including a 20 mm Gatling gun and launchers for guided missiles. System developement is expected to be completed in the second half of the 2020s and an order for about twenty MAH helicopters is expected.

So this maritime attack helicopter with AS332 Super Puma DNA, will provide the South-Korean Marine Corps a lot of additional firepower in the near future.

Wauw, you are now in South-Korea...
Thank you for sharing this photo, the ROKS Hansanda 81 is such a unique ship, good photos of it are hard to find on the internet.

South Korea Eyeing Larger Aircraft Carrier for its CVX Program - Naval News
Get away from the insanity happening around the RAN SSNs for a minute, to one of the most interesting, forward thinking, emerging Naval powers in the world. There is a report that South Korea may be looking at a larger Aircraft Carrier than previously reported. Something in the 50,000t+ range, operating a navalised version of the KF-21, so a STOBAR or possibly even a CATOBAR Carrier.

 

[StingrayOZ]

With two F-414 makes like a mini superhornet. Or a stealthish hornet with superhornet thrust. I would imagine it would have decent short field performance.

One of the previous carrier designs could be reconfigured with an angle deck and launchers. If you are spending this level of money in this age, probably go CATOBAR.

And I couldn't see ROK having any issues obtaining EMALS from the US, or help with fitting and learning how to operate a CATOBAR Carrier

Yes, it's quite a good looking aircraft on paper that has the potential to a good combat aircraft. It has a max ferry range of 1,550nm and a max thrust of 44,000lbs. In January it made its first supersonic flight.

South Korea's DSME to Design Arsenal Ship for ROK Navy - Naval News

The ROK Navy announced the selection of DSME for the concept design of an "Arsenal Ship" known locally as the "Joint Firepower Ship".

www.navalnews.com

Arsenal ships seems really getting traction with Japan and ROK. With Japan last year prepare two arsenal ships of 20,000 ton, now ROK getting on with three seems smaller arsenal ships range (although the final design has not lock yet, however seems 80 ballistic missile capabilities could be smaller then the Japanese ones).

Different is Japan aim for ABM carriers, ROK aim for ballistic and cruise missiles carriers for attacking land target in DPRK. Seems ROK believe ship borne launchers are better then Land Based launchers.

Rather then build this capabilities on Submarine, they are seems betting more on surface ships. Well the ships arsenal missile concepts, due provide larger capabilities them Submarine. Still the question is it enough to compensate submarine under water stealth advantage?

I noticed this link yesterday. Both projects seem like mega targets IMO. Japan’s desire for ABM carrier limits its design to a surface ship. SK could consider a submarine, certainly less vulnerable. I wonder how viable a diesel electric sub with a 100 tube capacity would especially if it was roaming the Korean Peninsula where endurance isn’t really needed so much?

South Korea Begins Construction on 2nd KSS-III Batch-II Submarine - Naval News

South Korea has begun construction on the second KSS-III Batch-II submarine. The boat, built by local shipbuilder Daewoo Shipbuilding & Marine Engineering (DSME), will be completed by 2026 and delivered to the Republic of Korea Navy (ROKN) in 2028 after undergoing sea trials.

www.navalnews.com

KSS III Batch 1 have 6 VLS, and Batch 2 have 10 VLS for their Hyunmoo ballistic missile. Thus building 3 arsenal surface ships each with 80 VLS do provide substantial add on Hyunmoo VLS capabilities. Even compare to add similar number land based TEL for Hyunmoo or their cruise missiles.

Building larger submarine seems ROK online media and analysts already ponder upon. However there's question to be decided whether larger submarine need to be Nuclear power or still diesel. KSS III already one of largest SSK only slightly smaller then Japanese ones.

Seems this arsenal ships being choose as they're realizing building something larger then KSS III need much more investment and time frame to work out. Personally I understand for 2 arsenal ships, but 3 ? Could they're better to use the money for third arsenal ships on adding more KSS III ? Then again seems they have another calculations being considered that are not public knowledge.

I-400-class submarine - Wikipedia
Of course, the Japanese built the largest DE Subs ever, the I-400 class, at 6500t and 122m they were the size of a Los Angeles SSN.

Two RNZN minesweeping trawlers, Kiwi and Moa sank the IJN submarine I-1 at Guadalcanal in 1943, It was pretty hefty even for those times with a submerged displacement of 2791 tons. They drove it aground with Kiwi ramming it twice. It mounted two 5.5in deck guns, one of which is now resident at the RNZN Museum in Auckland.

Would be interesting to see what defences and survivability features they have

Bemil Chosun put article on today signing in DSME for delivery to ROKN the second KSSIII submarine. This submarine being announced has more Korean Indigenous system and weapon suit.

DSME also put in the article that the tech in KSSIII version is mostly developed indigenously, thus also open for export potential.

Xavier video from Madex 2023 in Seoul. Shown new ships concepts from two leading ROK Naval Shipyards HHI (Hyundai Heavy Industry) and Hanhwa Ocean (new name of DSME).

HHI shown 3rd iterations of indigenous carrier, which is full fledge CATOBAR. HHI say this is 40000 tons 270m Carrier, but I do agree with Xavier it is probably heavier then that. I suspect it is full load between 50000 - 60000 which is close to QE Class and PANG. Also there's mock up on new KDX3 Aegis Destroyers and KDDX.

Hanhwa shown rival design, interesting also ROKN version of arsenal ships, potentially going to be enlarged. Not surprisingly as JMSDF already move on that direction too. Interesting their futuristic UAV carrier. Reminiscent of Marvel SHIELD carrier (just can't fly).

Yes, I watched that this afternoon. The HHI CV was quite interesting and it will be interesting to see how that progresses. The Hanwa Ocean (used to be DMSE) drone carrier is a very interesting concept.

 

[Ananda]

CVX 3 for me is quite bold concept, as such basically ROK try to cater couple problems right away at least:
1. Blue Water air coverage,
2. Increase population of KF-21.

Unlike JMSDF which relies on US carrier fighter (F-35B), ROKN CVX3 and even CVX2 relies on their KF-21N. Seems only CVX1 that just like JMSDF, they have to relies with US F-35B.

So they are trying to get more indigenous cash flow circulate within their own MIC, on this investment. There's question from previous administration of the affordability of even CVX1. That's why even CVX2 already quite ambitious, let alone CVX3.

Still if French can afford one CVN PANG, guess ROK can afford investment for one CVX3. ROKN already have enough surface fleet for escorts one carrier.

This is off course as answer toward Chinese CATOBAR program anyway.

Xavier another video from MADEX. This one talk on ROK latest submarine Janbogo/KSS III Batch II. This Submarine build by both Hanwha Ocean/DSME and HHI. Now both sign contract with Babcock teaming up to market KSSIII-II to Canada.

Later part in Video talk with Hanhwa Aerospace on their lithium ion battery. Asside using this on KSSIII-II, they are open to use their battery with other Euro producers in their design. In here talk on potential using their battery for whoever choose as winner in Netherlands Submarine program.

MADEX 2023: Hanwha Ocean Unveils KDDX-S Destroyer Design - Naval News

At MADEX 2023 Hanwha Ocean showcased several new ship designs. One of them was the KDDX-S "Smart Destroyer".

www.navalnews.com

Suppose to put this as further information on KDDXS concept.

https://m.facebook.com/story.php?story_fbid=pfbid0VwHqj8WzV6FSenLumyM9JSvGQDY9EZ9G9zHwsp4CUjkPeepJmCz2YPT5dH7eRnNpl&id=100064091161390&mibextid=Nif5oz

In their FB Naval news just add this KDDXS suppose to replace current KDX II ( if not mistaken 6 in inventory). This is shown evolving concepts as KDDXS aim also as mother ships for sea drones.
