A distinguishing feature of the ATx-20 boat is  its Vikhr-K gun/missile system including:

  • - Vikhr guided missile;
  • - AK-306 gun mount;
  • - TV gun/missile fire controland automatic target tracking
    system

In terms of its firepower the boat has no rivals worldwide in its class.

The ATx-20 boat is a high­speed skimming vessel. Its hull has deep V-shaped contours and is made from aluminum-magnesium alloy. The boat is designed to perform patrol missions, operate in territorial waters on call and supervise inner and outer roads of ports and harbors, as well as adja­cent littoral zones.

The basic version of the boat propulsion plant comprises two M 470 diesel engines, which develop a maximum power of 1,030 kW each, and two Arneson ASD-14 drives with partially submerged propellers.

The Project 12150V boat's navigation equipment consists of a navigation radar, a com­puterized electronic chart plot­ter, a gyrocompass, a magnet­ic compass, a passive sonar system, as well as a log and an echo sounder.

Radio communications facili­ties comprise:

  • - VHF radio stations (sta­
    tionary and portable);
  • - SW/DW radio station;
  • - COSPAS-SORSAT systemradio buoy.

In addition to the Vikhr-K gun/missile system, the Project 12150V boat is armed with a 14.5mm pedestal-mounted machine gun with an ammuni­tion allowance of 500 rounds. At customer's request, the boat can be armed with the 7.62mm PKMB machine gun, the AGS-17 automatic grenade launch­er, and the DP-64 hand-held grenade launcher for use against divers. Mangust is also equipped with an outboard motor-driven inflatable run­about boat provided with a launching gear.

One of the modifications of this project is the Mangust (Project 12150) patrol boat.
