The new warship Daejeon is the fifth of the country’s Daegu-class, 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 with the participation of the Commander of the Navy, Adm Boo Suk-jong. 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. Eight Daegu-class ships are planned, with the final goal of 20-22 frigates in the ROKN.

The Daegu-class is an improved variant of the Incheon-class frigate, capable of detecting or attacking targets such as ships and submarines significantly improved, to defend itself from aircraft and guided missiles, compared with existing frigates and patrol combat corvettes.

Daegu-class frigates are quite compact in size. The standard displacement of the FFX Batch II is 2,800 tons, and full load of 3,593 tons. She is 122m long (400 ft), the beam is 14m (46 ft) and the draft is 34m (13 ft).

According to the manufacturer, the survivability of the Daegu class has been maximized because it has a stealth design. Inheriting the Incheon-class hull design, however, the weapon system and superstructure were significantly changed on the Daegu-class frigates.

The hangar and a hellicopter deck on stern has been enlarged to support the operation of a 10-ton helicopter. Supported types include the Westland Super Lynx or AW159 utility types, serve as anti-submarine or anti-surface ship roles. Helicopters can assist in sea resupply, Search & Rescue missions, and in Over-the-Horizon reconnaissance work.

FFX-II is the first South Korean warship to be fitted with DRS Hybrid Electric Drive system, coupled with Rolls-Royce MT-30 gas turbine engine for Combined diesel-electric or gas integrated full-electric propulsion. This combination helps to maximize fuel savings while providing enhanced performance.
