South Korea Starts Bidding Process For ROK Navy’s KDDX Future Destroyer


The future destroyer class will displace about 8,000 tons, and is expected to feature K-VLS only (no MK 41 cells) to deploy the latest missiles by LIG Nex1 such as the naval variant of the Hyunmoo-3C (Eagle-3 독수리-3) cruise missile with a range of 1,500 km as well as the naval variant of the Cheongung 3 (also known as L SAM) with a range of 150 km. It will also feature an advanced integrated mast (I-MAST) combining several sensors (TACAN, ESM, IFF, UHF, VHF, IRST) and radar arrays (in S and X bands) in a single mast.


Naval News learned during Seoul Airshow (ADEX 2019) that KDDX is set to feature a BAE Systems’ Mark 45 5 inch main gun with the new automated handling system (set to be installed first aboard UK’s Type 26 frigate).

South Korea plans to deploy enhanced submarines in the next five years.


An official from the South Korea Ministry of Defense said, we will develop new submarines that will be able to carry more ballistic missiles than the existing Dosan submarines, which have six launching tubes. The submarine will be powered by a nuclear engine instead of diesel.

The South Korea Navy currently operates a submarine fleet of nine diesel-electric Jang Bogo-class (Type 209/1200) and seven Son Won II-class (Type 214) hybrid diesel-electric/fuel cell vessels with air-independent propulsion (AIP).

The Korean Attack Submarine program, KSS meaning Submarine, is a three-phased project to build up the Republic of Korea Navy (ROK Navy)'s attack submarine arsenal.

For the first phase KSS-I, the South Korean Navy acquired nine 1,200-ton Chang Bo-go class submarines. For the second phase, KSS-II, the South Korean Navy plans to acquire nine 1,800-ton Type 214 submarines equipped with Air-independent propulsion (AIP) the lead ship of her class, ROKS Sohn Won-il (SS 072) was launched at a shipyard of Hyundai Heavy Industries on June 9, 2006.

The third part of the program is the construction of nine local-made 3,000-ton diesel-electric attack submarines dubbed KSS-III equipped with air-independent propulsion and multiple vertical launch tubes able to fire Hyunmoo-3C cruise missiles at a range up to 1,500 kilometers.

In September 2018, Daewoo Shipbuilding & Marine Engineering (DSME) launched the Republic of Korea (ROK) Navy's first 3,000 tons submarine on September 14, 2018.

South Korea approves construction of 3 new KDX-III AEGIS destroyers


The South Korean Defense Acquisition Program Administration (DAPA) announced on 30 April 2019 that Ministry of National Defense (MND) has approved plans to construct a second batch of three (3) new AEGIS-equipped Sejong Daewang-class KDX-III destroyers worth KRW3.9 trillion (US$3.3 billion), and a second batch of three (3) Dosan Ahn Changho-class KSS-III diesel-electric submarines worth KRW3.4 trillion (US$2.92 billion) for the Republic of Korea Navy (ROKN).

DAPA expects contracts to support the programs to be concluded within the year.



The second batch of KDX-III is expected to be an improvement over the previous design in terms of naval and anti-submarine warfare capabilities. It will utilize the Lockheed Martin AEGIS Block 10 combat system and will be capable of intercepting ballistic missiles as well as an advanced air defense capability.

The ships are designed by Hyundai Heavy Industries (HHI), which was awarded the contract to design in 2016. It is expected that both HHI and Daewoo Shipbuilding & Marine Engineering (DSME), which built the first batch of KDX-III destroyers, will again share the contract to construct. DSME was recently acquired by HHI under a streamlining program.

The current KDX-III are currently the most powerful warship in the ROKN, and are equipped with a 127mm Mk.45 Mod.4 naval gun, a 30mm Goalkeeper CIWS, a Rolling Airframe Missile (RAM) Block 1 launcher, two triple anti-submarine torpedo tubes, four quadruple launchers for the SSM-700K Haeseong anti-ship cruise missiles, an 80-cell Vertical Launching System (VLS) for SM-2 Block IIIB / Block IV surface-to-air /ABM missiles, and a 48-cell VLS for Hyunmoo-3 land attack cruise missiles and K-ASROC Red Shark anti-submarine rockets.



The KDX-III have a full load displacement of 11,000 tons, are 166 meters long, with a beam of 21.4 meters, and a draft of 6.25 meters. They are powered by four (4) General Electric LM2500 gas turbines in Combined Gas and Gas (COGAG) configuration, enabling the ship to a maximum speed in excess of 30 knots and a range of 5,500 nautical miles.

It is also equipped with a hangar facility for two anti-submarine warfare capable naval helicopters, usually either the AgustaWestland Super Lynx or Sikorsky SH-60 Seahawk.
