The class of 129-metre longships was previously known as the FFX Batch III frigates and will displace 3,500-ton vessels. The frigate is scheduled to be constructed at HHI’s Ulsan shipyard and to be delivered in 2024.

The ship will also adopt a hybrid propulsion system designed to avoid detection by submarines. It can also operate at high speeds, up to 30 knots, using gas turbine in case of emergency, which will enhance its operational capabilities, according to Hyundai Heavy.

The ship will be equipped with a four-sided fixed multi-function phased array radar capable of 360-degree omnidirectional detection, tracking and engagement, which will significantly enhance anti-air defense capability.
