Norway’s Kongsberg Maritime announced on 23 January that it has secured a contract to supply its advanced propulsion and manoeuvring solutions for the two Indonesian Navy KCR-70 Fast Attack Crafts being built by Sefine Shipyard in Türkiye.
According to the company, the equipment package being supplied for the attack crafts includes a propulsion system that combines twin controllable pitch propeller (CPP) Promas systems that provide higher efficiency at patrol speeds with a single Kamewa waterjet for high-speed operation.
Kongsberg Maritime noted that the attack crafts will feature a combined diesel and gas turbine (CODAG) propulsion arrangement comprising twin diesel engines and a centrally positioned, 23-megawatt gas turbine that will directly drive the 160 cm diameter waterjet, which is capable of discharging more than 30 cubic metres of water per second.
“The use of twin Promas CPP for main propulsion, at speeds over 40 knots when the waterjet is used for boost power, is an innovative approach,” said Kongsberg Maritime, noting that it had carried out extensive hydrodynamic analysis to integrate the hull form and its propulsion system to ensure optimised performance and efficiency.
The 850 tonne KCR-70 Fast Attack Craft is based on Sefine Shipyard’s FACM-70 design and can be deployed for a variety of missions, including intelligence, surveillance, and reconnaissance (ISR) operations, anti-surface warfare, and anti-air warfare.
Construction of the two crafts commenced in October 2024 with a steel cutting ceremony witnessed by the Special Staff of the Chief of Naval Staff Vice Admiral TNI Retiono Kunto.
