The Sejong the Great class destroyers are among the most advanced warships afloat today. They were developed under the KDX-III program, which sought to provide the South Korean Navy with a world-class destroyer capable of meeting virtually any threat at sea, on land, or in the air.
Sensors consist of four AN/SPY-1D(V) phased array radar sets, an AN/SPG-62 fire control radar, a DSQS-21BZ hull mounted sonar, an MTeQ towed array sonar system, and a Sagem Infrared Search & Track (IRST) system. The AN/SPY-1D(V) is capable of being used as a passive radar, and the Sagem IRST is already a passive system, giving the Sejong the Great class immense situational awareness capabilities even at a maximum Emissions Control (EMCON) state, giving it substantial stealth capability.
At 8,500 tons standard displacement and 11,000 tons full load, the KDX-III Sejong the Great destroyers are the largest destroyers in operation with the South Korean Navy.
KD-III are also currently the largest ships to carry the Aegis combat system. They are bulkier and heavier than the U.S. Navy’s Arleigh Burke-class guided-missile destroyers and the Japan Maritime Self-Defense Force (JMSDF)’s Atago-class destroyers to accommodate 32 more missiles.
The destroyers’ main gun is the 127 mm/L62 Mk. 45 Mod 4 naval gun. Point-defense armaments include one 30 mm Goalkeeper close-in weapon system (CIWS) and a RIM-116 Rolling Airframe Missile (RAM) Block 1 21-round launcher. Anti-aircraft armament consists of SM-2 Block IIIA and IIIB in 80-cell VLS. Anti-submarine warfare armaments consists of both K-ASROC Hong Sahng-uh anti-submarine rockets and 32 K745 LW Cheong Sahng-uh torpedoes. Anti-ship capability is provided by 16 SSM-700K Hae Sung long-range anti-ship missile while the land-attack capability is provided by the Hyunmoo-3C cruise missile.

The Type 055 is a new class of multirole missile destroyer (DDG) currently under construction for the PLA Navy. The U.S. DoD has referred to the vessel as ‘Renhai’ class and classified it as a missile cruiser (CG) rather than destroyer. With an estimated displacement of 10,000 t, the Type 055 is the largest surface combatant ever introduced by the PLA Navy. At least four hulls are currently under construction in Dalian and Shanghai, with the first-of-class launched at the Jiangnan Shipyard on 28 June 2017.
The HHQ-9 is the naval variant of the land-based HQ-9 surface-to-air missile system developed in the 1990s. The missile may have adopted some Russian S-300 rocket motor and control technologies, with a “track via missile” (TVM) guidance system allegedly developed from the U.S. Patriot missile technology. The improved HQ-9A utilises a semi-active radar-homing, and on the HQ-9B variant this is complemented by a secondary infrared seeker. The missile has a stated maximum engagement range of 200 km, and is guided by the destroyer’s active phased array radar.
The HHQ-16 is the naval variant of the land-based HQ-16 surface-to-air missile, jointly developed with Russia based on the 9M38 series of missiles that form part of the Russian Almaz-Antey Shtil system China purchased for use on its Sovremenny class (Project 956E/956EM) and the Type 052B (Luyang class) destroyers, with features of the improved 9M317 missile. The missile has an operational range of about 40 km, though this has been extended to 70 km on an improved variant HQ-16B.
The close-in air defence is provide by a combination of the HHQ-10 short-range air defence missile and the Type 1130 close-in weapon system (CIWS). The HHQ-10 utilises a missile launcher is similar to the U.S. Navy RIM-116 in arrangement. Derived from the TY-90 short-range AAM, the HHQ-10 (or FL-3000N in its export name) is fitted with a dual passive radar-/infrared-homing seeker and has a maximum range of 9 km. An improved variant is reportedly fitted with an independent active infrared seeker, with a maximum range of 10 km.
The Type 1130 CIWS consists of the H/PJ-11 11×30 mm gun, H/LJP-349 fire-control radar, Type 4 electro-optical director (EOD), all incorporated in a single turret complex. Target acquisition is provided by the H/LJQ-364 radar installed on top of the bridge. The 11-barrelled H/PJ-11 gun has a firing rate of nearly 10,000 rounds/min, with a maximum firing range of 3,500 m against aircraft and 2,500 m against anti-ship missile
The Type 055 will be able to fire the YJ-18 ASCM from its VLS. The YJ-18 has been developed from the Russian 3M-54E Club-S, an export variant of the 3M-54 Kalibr (SS-N-27 ‘Sizzler’) anti-ship cruise missile (ASCM) used by the Russian Navy. The PLA Navy obtained 150 examples of the 3M-54E missile along with the Project 636M (Kilo class) submarines it received from Russia in 2004/05, and possibly produced the Chinese copy through reverse-engineering. Detailed information on the missile is not available but the 3M-54E missile can deliver a 200 kg warhead to a maximum range of 220 km (or 300 km on the 3M-54E1) at a speed of Mach 2.9 in the terminal stage of an engagement. The missile is powered by a turbojet engine and employs an inertial guidance plus terminal active radar-homing.
The main gun on the bow deck is an indigenous H/PJ-45A single-barrel 130 mm/70-calibre naval gun developed by Zhengzhou Institute of Machinery and Electronics (713 Institute) and built by the Second Inner Mongolia Machinery Plant (447 Factory). The H/PJ-45A is modelled after (but not a direct copy of) the Russian AK-130 automatic naval gun, and can be operated in fully automatic mode from the radar control system, from the shipborne optical sighting system, or laid manually. The gun can fire 86.2 kg projectiles at a maximum rate of 40 rounds/min to a maximum range of 30 km.
The Type 055 is equipped with a new active phased array radar (APAR) system, consisting of four larger flat arrays working in the S/C-band, and four smaller arrays working in the X-band. The dual-band radar system incorporates a variety of functionalities including air/sea surveillance, target acquisition, and fire-control previously performed by different radar systems, avoiding electromagnetic interferences and allowing an integrated intelligence, surveillance, target acquisition and reconnaissance (ISTAR) capability. The radar system is also believed to be capable of detecting ballistic missile targets and guiding missile interceptors, providing the Type 055 destroyer with the ballistic missile defence (BMD) capability.

Both ships are large, representing the last large class destroyer, so who will win?
