Norwegian marine technology company Kongsberg Maritime has secured a contract to supply advanced propulsion and maneuvering systems for two KCR-70 Fast Attack Craft built for the Indonesian Navy. The vessels are currently under construction at Sefine Shipyard in Türkiye.
Kongsberg Maritime’s equipment package features an advanced propulsion system that integrates twin controllable pitch propeller (CPP) Promas systems for enhanced efficiency at patrol speeds, along with a Kamewa waterjet to deliver additional power for high-speed operations. This configuration optimizes propulsion performance, speed, and maneuverability, ensuring superior efficiency and capability for the new vessels.
The vessels will have a Combined Diesel and Gas Turbine (CODAG) propulsion system featuring twin diesel engines and a centrally located 23-megawatt gas turbine. This configuration directly powers a 160-centimeter diameter waterjet, capable of expelling over 30 cubic meters of water per second, ensuring enhanced speed and performance.
The integration of twin Promas controllable pitch propellers (CPP) for primary propulsion, combined with a waterjet for boost power at speeds exceeding 40 knots, represents an innovative approach. Kongsberg Maritime conducted a comprehensive hydrodynamic analysis to optimize the hull design and integrate two propulsion systems, enhancing maneuverability, speed, and overall efficiency.
The KCR-70, derived from Sefine Shipyard’s FACM-70 design, is a 70-meter fast attack craft engineered for multi-mission capabilities, including intelligence, surveillance, and reconnaissance (ISR) and anti-surface and anti-air warfare. With a displacement of 850 tonnes, the vessel can achieve speeds exceeding 40 knots. It has an operational range of 1,600 nautical miles and an endurance of seven days, making it well-suited for extended missions across various operational environments.
The FACM-70 is designed for various primary missions, including intelligence, surveillance, and reconnaissance (ISR) operations, anti-surface warfare, and anti-air warfare. These vessels can also conduct patrol missions in challenging conditions, such as nighttime operations and restricted visibility while maintaining extensive radar coverage. Additionally, they support surface combatants during naval operations and engage in missions against asymmetric threats. The FACM-70 can also perform Search and Rescue (SAR) operations in combat zones or adjacent areas, ensuring critical support across diverse mission scenarios.
