Key Points

  • The Republic of Korea Navy’s second Dokdo-class ship will feature a different set of weapons and sensors from its predecessor
  • Improvements have been incorporated from the service’s 11-year operational experience with the first-of-class

The Republic of Korea Navy’s (RoKN’s) second Dokdo-class helicopter carrier, which will be known in service as ROKS Marado with pennant number 6112 once commissioned, has been built to carry a different suite of weapons and sensors from the first-of-class.

Images from the Marado ’s ceremonial launch on 14 May reveal that South Korea has selected the ELM-2248 (MF-STAR) multifunction surveillance radar from Israeli defence firm ELTA Systems in place of the SMART-L multibeam radar from Thales found on ROKS Dokdo (6111).

The country has also selected what appears to be the SPS-550K three-dimensional air and surface surveillance radar from local company LIG Nex1, in place of the Thales MW08 surveillance radar found on the first-of-class.

Also, notably absent is the Raytheon Mk 49 guided missile launching system capable of deploying the RIM-116 Rolling Airframe Missile (RAM), which is found atop Dokdo’s bridge. On Marado , this has been replaced with a single fixed-array face of the MF-STAR radar mast located amidships.

Illustrations released by South Korea’s Defense Acquisition Program Administration (DAPA) on Marado indicate that the ship will be armed with two 20 mm Phalanx close-in weapon system (CIWS) turrets. These will be located on deck in the bow section, and on a depressed pedestal at stern.

Close-in protection on Dokdo is provided by two Thales Goalkeeper turrets, which are located on the ship’s superstructure and on deck, also in the bow section.
