The Indonesian Navy Clurit-class (KCR-40-class) fast missile craft, KRI Clurit (641) and KRI Kujang (642) successfully fired two chinese-made C-705 anti-ship missilesâ€‹ and sank former oiler KRI Balikpapan (901) at Natuna, South China Sea. The two missiles were fired from a range of Â±70km. The Sinking Exercice (SINKEX) was part of the initial preparation ahead of the Armada Jaya Exercise, which is the main training exercise of the Indonesian Navy. The Indonesian Navy released a video of the SINKEX which took place 8 April 2021.
The Clurit class fast attack craft are a class of domestically designed and built warships operated by the Indonesian Navy. Vessels of this class are named after indigenous weapons and swords used in Indonesia. The Clurit was built by PT Palindo Marine Industries, Tanjunguncang, Batam. PT Palindo also worked with Daewoo Shipbuilding and Marine Engineering’s Daesun Shipyard in South Korea on the design and construction of four Makassar class landing platform docks. The Clurit is named after a curved blade weapon native to the Madurese people of East Java.
The Clurit prioritizes the element of surprise, rapid strike, destroying multiple targets at once and avoidance. She have a length of 44 meters, a displacement of 250 tons, a crew complement of 35 sailors, a top speed of 30 knots. The first four of the class were originally armed with just a Denel (Vektor) 20mm cannon and two 12.7 mm machine guns. In May 2014 the Clurit and Kujang were fitted with a Chinese made six-barrelled NG-18 30mm CIWS and two of the new C-705 SSM. Although the first C-705 have been fitted, it is not clear when they will become operational.
The C-705 is a Chinese anti-ship missile. The missile was developed by the third research institute of the Chinese Aerospace Group, also the manufacturer of the C-701 and C-704. This anti-ship missile is designed specifically for targets with displacement between 1,000 tons to 4,000 tons. The warhead is reduced to 110 kg, but the adaption of HVTD-H high-explosive directional warhead. Indonesia hopes to licence-build the C-705, which is a derivative of the Chinese C-704 anti-shipping missile with a turbojet to extend the range to 120 kilometres (65 nmi).
