South Korea intends to purchase four more Phalanx close-in weapons systems (CIWS) to equip its naval ships, US congressional records show.
In a notice to the US Congress published in January, it was revealed that South Korea requested “the inclusion of an additional four MK 15 MOD 25 Phalanx Block 1B Baseline 2 (IB2) CIWS.” Also included are AA20 ammunition, AA61 ammunition, spare parts, personnel training and contractor support.
