Stealth wave-piercing trimaran carbon fast attack craft (DNVGL Patrol Boat) KRI Golok (688) built by PT Lundin Industry Invest (also known as North Sea Boats) was launched today with a ceremony held at the shipyard in Pantai Cacalan, Jawa Timur. The fast attack craft (FAC) employs a modern “Wave Piercing” trimaran design. This allows the vessel to cut-through waves rather than rise up and over them, and the increased beam provides inherent stability. This combination of features reduces both pitching and rolling, creating a stable weapons platform, and enabling the vessel to comfortably and safely maintain higher average speeds in adverse conditions.
The fast attack craft has “Stealth” design characteristics, and incorporate features that minimise detection by reducing Radar, Infra-Red, Acoustic and Magnetic signatures. Stealth properties are further improved as there are no reverse-angle bow overhangs to reflect radar signals, as seen on conventional hull forms. The total length of the KRI Golok (688) is 62.53 meters. It has a width of 16 meters, a height of 18.7 meters, and a weight of 53.1 tons. This stealth trimaran has a top speed of 28 knots and a cruising speed of 16 knots. It is equipped with a 30 mm cannon and a 12.7 mm gun. It can carry 25 crew members. The boat made of composite material which has the advantages of high specific strength and has excellent fatigue/corrosion resistance.
The Indonesian Navy ordered the first of four for delivery starting in 2012. The first of these was named KRI Klewang (model number X3K) and was launched on 29 August 2012; however, only four weeks later the trimaran carbon fast attack boat caught fire on 28 September while undergoing fit-out in Banyuwangi, and was completely destroyed. Therefore, this ship can be used as a prototype trimaran ship, for development purpose. The Klewang-class trimaran was designed in partnership with New Zealand based naval architects LOMOcean Design Ltd. over a period of 24 months. The ship has been designed to operate in sea states with 6-meter high waves.
