HD HHI's HDF-6000 Frigate for Royal Saudi Navy.
Interview with HD Hyundai Heavy Industries during World Defense Show (WDS) 2026 in Riyadh, Saudi Arabia. The Korean shipbuilder is proposing the advanced HDF-6000 frigate to the Royal Saudi Navy for their next generation frigate requirement.

=====================

HDF-6000 is a high-end, 6,500-ton frigate specialized for long-endurance, long-range blue-water operations. The vessel features a reduced radar cross-section (RCS) hull design that maximizes stealth performance, and it is equipped with capabilities for ballistic missile detection, tracking, and interception. Built on the hull of the ROK Navy’s KDX-II, frequently deployed for Escort Task Group in the waters off Somalia, the HDF-6000 incorporates a large stern flap, which contributes to improved stability in high sea states, particularly enhancing helicopter operation safety.
