MADEX 2021: LIG Nex1, Hanwha Systems showcase competing designs for RoKN's CIWS-II programme

by Dae Young Kim & Gabriel Dominguez

South Korean companies LIG Nex1 and Hanwha Systems have showcased models of the close-in weapon systems (CIWSs) each of them is proposing to meet the Republic of Korea Navy's (RoKN's) ‘CIWS-II' requirement.

Under the programme the RoKN aims to acquire a locally developed CIWS for use on its future warships, including the service's light aircraft carrier, KDDX guided-missile destroyers, and FFX-III-class guided-missile frigates. Janes understands that South Korea is aiming to complete development of the system by December 2030 for about KRW320 billion (USD287 million), with Seoul formally opening the bidding process for the project in May.

To meet this requirement LIG Nex1 displayed a CIWS model featuring a 30 mm Gatling-type gun capable of firing 4,200 rounds per minute; a tracking active electronically scanned-array (AESA) radar; a non-rotating, four-faced AESA search radar; and an electro-optical targeting system (EOTS) at the 9–12 June International Maritime Defense Industry Exhibition 2021 (MADEX 2021) in Busan, South Korea.

While the radars will be locally designed and built, the weapon is not likely to be a locally developed one but rather the same GAU‐8/A Avenger seven-barreled autocannon used by the Goalkeeper CIWS, which is already in service with the RoKN.

Hanwha Systems displayed a CIWS model with a more stealthy design but with similar radar and EOTS features. It seems the Hanwha design would also employ the same GAU‐8/A Avenger seven-barreled autocannon.

It is possible that these firms will team up with foreign companies, such as Thales or Raytheon, to secure the development contract.
