Hyundai Heavy Industries (HHI) has received a KRW400 (USD325 million) contract to design and build the first Ulsan-class Batch III frigate for the Republic of Korea Navy (RoKN).

The ship is the first of six 3,500-tonne frigates planned for the batch. The contract covers detailed designed work and construction of the first-of-class.

The ship will have an overall length of 129 m and a width of 15 m. It will feature a hybrid electric and gas propulsion system, and can attain a maximum speed of 30 kt.

The frigate can utilize its electric propulsion systems during anti-submarine operations to minimize its acoustic signatures. Accordingly, the vessel will rely on gas turbine propulsion when it needs to operate at high speeds, said HHI.

HHI also noted that the warship will be equipped with a four-sided fixed multifunction phased array radar “capable of 360-degrees omni-directional detection, tracking, and engagement”.

The ship will be constructed at HHI’s shipyard in Ulsan and is scheduled to be handed over in 2024.
