The Republic of Korea (ROK) will acquire Raytheon’s Standard Missile (SM)-6 for its upcoming KDX III Batch II ∂єѕтяσуers. Also known as RIM-174 Standard Extended Range Active Missile (ERAM), the SM-6 can perform anti-air ωαяƒαяє (AAW), вαℓℓιѕтι¢ missile defense (BMD) and anti-surface ωαяƒαяє (ASuW) missions
The decision to go ahead with the SM-6 procurement was made at the 143rd meeting of the Defense Acquisition Program Promotion Committee presided over by Minister of National Defense Suh Wook and held on the 26th.
The ROK government will invest ₩760 billion (around $600 million) from 2023 to 2031 to acquire the SM-6. The missiles will be deployed on the three Aegis-equipped King Sejong the Great-class (KDX-III) Batch-II ∂єѕтяσуers which will be delivered to the Republic of Korea Navy (ROKN) starting from 2024.
The ROKN had received significant criticism over its lack of anti-вαℓℓιѕтι¢ missile capabilities. This is because its current fleet of Aegis-equipped ships can only provide early warning of incoming ballistic missiles and are unable to actually intercept them.
The SM-6 has a range of 240~460 km, around twice the 170 km range of the SM-2, currently in service with the ROKN. This means that it will help the ROK ∂єƒєи∂ αɢαιиѕт вαℓℓιѕтι¢ missile threats, mainly from North Korea.
About SM-6A, according to Raytheon, the RIM-174 Standard Extended Range Active Missile (ERAM), or Standard Missile 6 (SM-6) is three missiles in one: It’s the only ωєαρσи that can perform anti-air ωαяƒαяє, вαℓℓιѕтι¢ missile defense and anti-surface ωαяƒαяє missions. The system offers navies more flexibility in limited ship space. The missile has an operational range up of about 370 km and a top speed of March 3.5.
About the KDX-III Batch-II
Hyundai Heavy Industries announced that it signed a contract with the Defense Acquisition Program Administration (DAPA) for the three ships of the KDX-III Batch-II on October 10th 2019.
The program will deliver one ∂єѕтяσуer every two years, starting from 2024. The ships will receive the pennant numbers 995, 996, and 997 and have an empty displacement of 8,100 tons, around 500 tons more than the KDX-III Batch-I. The ships will be 170 m in length, 21 m in width, and have a top speed of 30 knots. The three existing 7,600-ton KDX-III Batch-I ships are based on the DDG 51 Arleigh Burke-class ∂єѕтяσуers of the US Navy.
According to our South Korean sources, the KDX III Batch II ships will feature a total of 88 vertical launch system (VLS) cells:
48x Mk41 VLS for US-made missiles
16x K-VLS
24x K-VLS II
The KDX-III Batch II will be fitted with Raytheon’s SM-3 Block IB interceptors, SM-2 Block IIIB as well and the new SM-6 “multi-mission missile” capable of long-range Fleet Air Defense, Sea-Based Terminal defense, and Anti-Surface Wαяƒαяє.
K-VLS will be used to deploy K-SAAM (Korean Surface to Air Anti Missile), replacing the RIM-116 Rolling Airframe Missile (RAM). It features inertial mid-course guidance and a dual microwave and infrared homing seeker for terminal guidance. K-VLS will also deploy Hong Sang Eo (Red Shark) rocket-based torpedo (K-ASROC) and Haeryong Tactical Surface Launch Missile (TSLM) land αттα¢к cruise missile.
K-VLS II are larger cells currently being developed by Hanwha to launch the future long-range surface-to-air missile (150 Km range) Cheongung 3 (also known as L SAM). Naval News learned from a source at LIG Nex1, that the naval L SAM (which is still in conceptual phase) will only have minor modifications compared to the land-based variant. L SAM is intended to replace SM-2 in the ROK Navy. K-VLS II will also likely be used to launch the new supersonic anti-ship missile.
