Military ship i.e. frigate type ship, has main propulsion unit with two driving units that drive ship in transit conditions, and secondary propulsion unit with hydrojet driven by third unit to move ship in military utilization conditions
The ship has a propulsion device (2) comprising a main propulsion unit (3) constituted by two lateral line shaftings (4a, 4b), where each shafting carries corresponding propellers (5a, 5b) driven by two driving units (6a, 6b). The driving units of the propulsion unit drive the ship in transit navigation conditions, where each driving unit comprises corresponding speed-reduction gears (8a, 8b) and diesel engines (7a, 7b). A secondary propulsion unit (10) has a hydrojet (11) driven by a third driving unit (12) for moving the ship in military utilization conditions.
