"Strazh" is a project of a submersible patrol ship developed by the Rubin Design Bureau, combining the advantages of a submarine and a surface patrol ship.

The ship's cruising range is up to 4000 miles (about 6437 km) at a speed of 10 knots (about 18.52 km/h).

The ship's armament will include a small-caliber automatic cannon, two launchers for guided missiles and four torpedo tubes.

The ship will have two sealed multifunctional hangars to accommodate lifeboats and weapons of inspection teams, unmanned aerial vehicles or other payloads.

To search for intruders, both a radar station and hydroacoustic antennas are used - this will allow you to secretly detect targets and quietly approach them.

The ship can also be used for training its own anti-submarine forces and training crews of classic submarines.
