Kongsberg Maritime Secures Advanced Propulsion Contract for Indonesian Navy’s Fast Attack Craft

The cutting-edge propulsion system combines twin controllable pitch propeller (CPP) Promas systems with a central Kamewa waterjet for boost power. This hybrid configuration enhances speed, manoeuvrability, and efficiency, making the vessels capable of exceeding 40 knots during high-speed operations.

Each craft will utilise Combined Diesel and Gas Turbine (CODAG) propulsion, incorporating twin diesel engines and a 23-megawatt gas turbine. The turbine directly drives the waterjet, which discharges over 30 cubic metres of water per second, providing substantial thrust and performance.

Kongsberg Maritime’s innovative integration of twin Promas CPP systems and the waterjet was achieved through extensive hydrodynamic analysis. This design optimises the hull form, delivering superior operational performance for the vessels in various missions.

The 70-metre KCR-70 is designed for intelligence, surveillance, and reconnaissance (ISR) missions, as well as anti-surface and anti-air warfare. With a displacement of 850 tonnes, a range of 1,600 nautical miles, and a seven-day endurance, the craft is well-suited for extended deployments in diverse conditions.
