Grachonok-class anti-sabotage patrol boat (Project 21980)

The Grachonok-class anti-sabotage patrol boat, Russian Project 21980, is a small Russian naval security craft designed by KB Vympel and built at several Russian shipyards to protect basing areas, ports, and critical maritime infrastructure. The class combines sonar and electro-optical surveillance with grenade launchers, a 14.5 mm heavy machine gun, and Igla MANPADS, making it a compact diver-hunting and harbor-defense platform.
