Hida

The Hida-class patrol vessel are a class of patrol vessel within the PL series (Large patrol vessel) of the Japan Coast Guard (JCG). The class name "Hida" is named after Hida Mountains, the northernmost mountain range of the Japanese Alps, a famous mountain range in Japan. The class is one of the more modern patrol vessel classes designed to intercept North Korean (DPRK) spy boats. These classes are referred to as "High-speed, high-functionality patrol vessel, large" (高速高機能大型巡視船). The vessels carry a Bofors 40 mm L/70 autocannon with a laser-optical fire-control system, and are able to safely deal with heavily armed spy boats of the DPRK which intrude into Japanese waters. The hull of this class is bulletproof in cases of close-range firefights using small arms. Ships of this class are among the leading vessels of flotillas intended for spy boat interception.
