ZALA unveils Russian propulsion system for unmanned boats

The complex combines the marineized KAMA-150 gasoline engine and KAMA-180 waterjet. The engine is based on the domestic ZMZ unit, featuring a custom cooling system and control software.

The 2.7-liter four-cylinder engine paired with an 180mm impeller provides strong thrust at low speeds, enabling operation in shallow or overgrown waters where conventional propellers are vulnerable.

This fully localized powertrain reduces dependence on imported components and simplifies mass production of unmanned craft and patrol vessels. Krylov State Scientific Center officials highlighted the restoration of such systems as a key task for Russia's small fleet.
