An artist rendering of South Korea’s new Chamsuri-211 fast patrol boat
NavyRecognition is reporting the South Korean Navy will be getting the first of a new class of Patrol Craft in late 2017. It is a bit smaller than the Webber class at 44 meters in length and 210 tons. It is designed specifically to counter North Korean Hovercraft. It is armed with a 76 mm gun and a pair of remotely operated, radar controlled 12.7mm (.50 cal.) machine guns. The unusual weapon seen on the stern is a launcher for 130mm (5.1″) guided rockets (apparently twelve) . (I suspect these are actually guided versions of the 5″ Zuni rocket, much like the APKWS is a guided version of the Hydra rocket. )
The vessels is expected to have a max speed of about 40 knot and will apparently be powered by waterjets. I don’t see any boat on the artist impression above.
