The characteristics of rocket boats of the Nongo type, as, indeed, of all North Korean vehicles, are kept secret. It is known that their length is 35 or 40 m (depending on the version), and the displacement reaches 200 tons. Thanks to the use of an air cushion, the boats can reach speeds up to 48 nodes (90 km / h).
Each of the boats is equipped with an 57 or 76 mm caliber gun mount, as well as several 30-mm rapid-fire cannons. In addition, according to unconfirmed information, they can be armed with X-35 missiles. A special feature of Nongo type boats is their “stealth-like” shape. According to unofficial information, the North Korean fleet received six such boats.
