The latest modification is the ship's largest version about 72 meters long with its standard displacement of about 1,300 tonnes, the press office specified.

Like its other modifications, the patrol ship has two air-tight multi-purpose hangars to accommodate boats and the armament of inspection groups. Both radars and sonar antennae can be employed to hunt down intruders: these capabilities allow stealthily spotting and approaching targets, the press office specified.

The ship that combines underwater and above-water properties and "is intended for its use in peacetime, keeps its worthiness as a combat unit in the event of a conflict escalation," Rubin stressed.

The Strazh submersible patrol ship is being engineered as an "easy-to-adjust" vessel and its modifications and capabilities can vary. Its characteristics make it possible to offer a vessel most customized to particular tasks, conditions, and possibilities, Rubin said.

TASS reported in April 2021 that the Rubin Central Design Bureau had developed the first Russian submersible patrol ship designed for foreign customers. The project was dubbed Strazh and will be offered to the world market under the BOSS designation.
