For two months the boat passed the full cycle of state tests at the combat training grounds of the Northern Fleet.

Designed for detachments to combat underwater sabotage forces, the boat is equipped with a hydroacoustic complex, which allows detecting moving and stationary objects at different depths and distances.
Against surface, coastal and air targets, the anti-sabotage boat can use a large-caliber machine gun, which is located in the nose and can operate in both manual and automatic control modes.
Also, a pressure chamber was installed on the boat of the Rook project to ensure the safety of diving descents to medium depths and a video surveillance system was used for the surface situation.
The crew of the boat can carry out visual monitoring of the underwater environment using an uninhabited underwater vehicle.
