The Daegu-class frigate is a class of guided-missile frigates of the Republic of Korea Navy (ROKN). The Daegu-class is based on the preceding Incheon-class frigate and has otherwise been referred to as an Incheon-class batch II, or FFG-II.

The Daegu-class is the first Korean warship to be equipped with a combined diesel-electric or gas (CODLOG) propulsion system. The propulsion system of the ROKN ships has a gas turbine direct drive and four high-speed diesel generators driving two Leonardo DRS permanent magnet electric motors.

The Daegu-class frigate is armed with one 5-inch (127-mm)/L62 caliber Mk-45 Mod 4 naval gun, one 20-mm Phalanx CIWS (Close-In Weapon System), two triple torpedo tubes for K745 Blue Shark torpedo, eight SSM-700K Haeseong Anti-ship Missile and 16-cell K-VLS (Vertical Launching System) able to launch Haegung K-SAAM surface-to-air missile, Haeryong VL-Tactical anti-ship cruise Missiles and K-ASROC Red Shark anti-submarine missile.

The launch ceremony for the 2,800-ton FFG-II Seoul took place at Hyundai Heavy Industries Co.’s shipyard in the southeastern port city of Ulsan, according to the Navy. It is the third frigate to be built under the project to secure a second batch of such vessels to replace the Navy’s aging frigates and patrol combat corvettes.

The 122-meter-long/400-foot-long ship is equipped with guided missiles and guns and can carry a helicopter for marine operations, the Navy said. The latest version, in particular, boasts advanced anti-submarine patrol and combat capabilities, as it employs an advanced sonar system as well as a hybrid propulsion system that reduces the level of noise the vessel makes underwater, it added.

It will be delivered to the military in early 2021 after additional preparations are completed, and several more vessels of this class will be built by the early 2020s, according to the Navy. Defense Minister Jeong Kyeong-doo attended the ceremony and celebrated the launch of the new frigate as well as the 74th anniversary of the foundation of the Navy.

«Uncertainties in regional maritime security situations have continued due to feuds over maritime jurisdiction and freedom of navigation. … Under these circumstances, we should secure more powerful naval capabilities», Jeong said in his congratulatory remarks. «We will firmly protect national security and maritime sovereignty by perfectly carrying out all missions in seas surrounding the Korean Peninsula and the world», he added.
