Grachonok class, Russian designation Project 21980 Grachonok, is a class of anti-saboteur
and large guard boats being built for the Russian Navy. The class is designed
to combat sabotage and terrorist forces and means in the waters off bases and
near the approaches to them, as well as to assist the Border Service of the Federal
Security Service of the Russian Federation in solving the problems of preservation
and protection of the state border of Russia.
This is a single-deck boat
with a steel hull and a wheelhouse made of aluminum-magnesium alloys, with a continuous
main deck, a developed superstructure, inclined bow and transom stern. For work
at the stern of the boat there is a crane. Propulsion is from a twin marine diesel
engine arrangement that can propel the modern design to speeds of 23 knots in
ideal conditions. Since heavy automation is built into these boats, only a crew
of eight is needed for maximum function. The boat can stay at-sea for as many
as five days with the onboard fuel and food stores. Aboard is the MR-231 Pal system
used for navigation and the Kalmar is the main sonar fit while the MG-757 Anapa-M
is the towed sonar array. An MTK-201M2 provides as eletro-optical television functionality.
Armament is a DP-65A remote-controlled rocket grenade launcher and a DP-64 series
grenade launcher. There is also a single 14,5-mm MTPU heavy machine gun and an
Igla-1 man-portable SAM system (four missile reloads) as well as any personal
weapons carried by the crew.
