| Source measurement | — | Ships of this class are equipped with one single-mounted Mk44 Bushmaster II 30mm autocannon with laser-optical fire-control system . The 30 mm caliber autocannon is an entirely new caliber for the JCG, and it gives this class increased firepower compared with usual 1,000 ton-class patrol vessels which normally have only one manually controlled 20 mm Vulcan Gatling gun . This 30 mm gun system is more powerful than a 20 mm Vulcan with a Remote Firing System (RFS) associated with the simplified laser-optical fire-control system (FCS) which is on board recent PMs and PSs such as the Tsurugi class , and more reasonable than the larger Bofors 40 mm L/70 gun with laser-optical FCS which is mounted on board "High-speed, High-functionality" PLs such as the Hida and Aso classes .[source]Hateruma-class patrol vessel · Lead; only the objects and conditions stated in this passage The Shiretoko class is the older 1,000 ton-class PLs, twenty-eight ships were built in late 1970s and early 1980s. It was announced that Japan plans to transfer two of the older Shiretoko -class type patrol vessels to the Philippines Coast Guard in 2012.[source]Hateruma-class patrol vessel · Lead; only the objects and conditions stated in this passage |
