ROKS Daejeon (FFG-823) was launched by Daewoo Shipbuilding & Marine Engineering (DSME) today (May 3).

The new warship Daejeon is the fifth of the country’s FFX Batch II frigates to replace the Navy’s 1,500-ton frigates and 1,000-ton patrol combat corvettes, according to the South Korean Navy.

The ceremony was held at its manufacturer Daewoo Shipbuilding & Marine Engineering Co.’s Okpo shipyard on the southern island of Geoje, with the attendance of Chief of Naval Operations Adm. Boo Suk-jong.

With 120 crew members aboard, the 122-meter frigate will carry various weapons, including ship-to-ship and surface-to-ground missiles, as well as a helicopter for naval operations.

The new frigate has improved capability to detect and attack submarines with a towed array sonar system and a long-range antisubmarine torpedo, according to the South Korean Navy.

The new warship will be delivered to the South Korean Navy by the end of the next year after a trial period.

SEOUL, Aug. 4 (Yonhap) -- South Korea decided to acquire a new frigate with improved anti-aircraft and survival capabilities through domestic research and development, the arms procurement agency said Wednesday.

The defense project promotion committee held a videoconference and approved the plan for the 3.5 trillion won (US$3.1 billion) Ulsan-class Batch IV project, according to the Defense Acquisition Program Administration.

"The project is expected to enhance the military's maritime operational capabilities, as well as contribute to securing up-to-date technologies and creating jobs," the agency said in a release.

The total budget for the program, which will run from 2023-2032, is subject to review and confirmation following a feasibility study. Hyundai Heavy Industries Co. is currently developing South Korea's new 3,500-ton frigates under the Ulsan-class Batch III project that began in 2016.

During Wednesday's meeting, the committee also decided to change the lead developer for the upgrade of light torpedoes from the state-run Agency for Defense Development to a local company. The change is expected to help the local defense industry enhance its capabilities to conduct various research projects, the agency said.
