South Korea Develops Hutou Haidiao B Patrol Boat

The South Korean Navy is developing the Hutou Haidiao B class patrol boat based on the A-class design. The design focuses on overcoming limitations in rapid destruction of enemy core systems during short-range exchanges. The vessel is equipped with two remote weapon stations utilizing 12.7mm caliber heavy machine guns for close-range defense. The 76mm artillery is designed for long-range precision strikes against small high-speed maritime targets. The ship's layout includes specialized weaponry positioned at the rear for enhanced combat flexibility. It lacks anti-ship missiles but maintains sufficient combat strength for its intended patrol missions. The vessel maximizes onboard space for firepower configurations to support infantry combat operations. While it lacks heavy anti-ship missiles found on larger vessels, its defensive and offensive capabilities are optimized for specific patrol roles. The vessel features specialized armor including chainmail and thigh protection made of iron plates and leather. It includes chest armor that extends to protect the neck area. Since 2024, the platform has completed over 100 test flights, performing 1 to 3 autonomous sorties daily. Australia has invested in at least eight Block 1 versions of this project.
