The Republic of Korea Navy has commissioned the frigate ROKS Jeju (FFG-827), the sixth vessel in the Ulsan-class Batch III frigate programme, as part of its ongoing effort to modernise its surface fleet and strengthen multi-domain maritime capabilities.
The 3,500-tonne frigate is designed with a hybrid propulsion system aimed at reducing acoustic signatures, improving survivability in anti-submarine warfare environments. It is capable of reaching speeds of up to 30 knots, providing high operational flexibility for rapid response missions.
ROKS Jeju is equipped with an advanced active electronically scanned array (AESA) radar system offering full 360-degree coverage, enhancing detection and tracking of aerial and surface threats. The vessel also features a vertical launch system capable of deploying air defence and anti-submarine missiles, alongside anti-ship missile systems and a 127 mm main gun.
The commissioning of the frigate reflects South Korea’s continued push towards greater self-reliance in defence manufacturing and its ambition to expand competitiveness in the global naval export market through advanced indigenous warship designs.
