VESSEL REVIEW | ROKS Chamsuri-231 – Rocket-armed fast patrol boat for Republic of Korea Navy

South Korea's ROKS Chamsuri-231 is a rocket-armed fast patrol boat built to replace older coastal patrol craft and strengthen the navy's response to small surface threats. The approximately 44-meter vessel uses combined diesel-and-gas propulsion driving waterjets for a maximum speed of 40 knots. Its armament comprises a Hyundai Wia 76 mm main gun, two remotely operated 12.7 mm machine-gun stations and a stern-mounted 12-cell launcher for 130 mm Biryong guided rockets. Search radar and electro-optical tracking support surveillance and weapon employment, combining gunfire and guided-rocket engagements within the same compact littoral combat platform.
