Small-sized remotely controlled anti-diversion grenade launcher system DP-65 is designed to defend:

• the ships against attacks of underwater swimmers at the outer roadsteads, basing points and at the open anchorages;

• the water-development works, sea-based platforms and other key sea-based and coastal installations against attacks of underwater swimmers.
• 
  

System DP-65 is used for:

• the grenade launcher aiming at the target coordinates formed by the sonar;

• the target marking by launching signal rocket grenades ГРС-55;

• the target destruction by single or salvo launching of rocket grenades РГ-55М.

When using with sonar station “Анапа-МЭ”, system DP-65 ensures automatic detection of the target, its classification and designation, as well as, automatic use of grenade launcher 98У when aiming at the target and its tracking.
