The DP-64 is a Russian special-purpose double-barreled over/under grenade launcher designed to protect ships, dockyards, water development works, and other coastal installations from combat swimmers and naval special forces. The weapon is breech-loading and operates much like a large shotgun with a side-break breach, utilizing both direct and indirect iron sights. The weapon is capable of firing grenades indirectly at ranges up to 400 meters; however, these grenades act much like small depth charges, attacking submerged swimmers like true depth charges attack submersibles. A large polymer stock and the barrels themselves makes up the bulk of the weapon. The barrels are selected by turning a lever accommodated above the trigger guard. A front pistol grip is equipped for support and is out of alignment with the rear grip and trigger mechanism, providing a more natural grip while firing indirectly. The butt is fitted with a springy rubber pad used to diminish recoil. Direct fire sights are also provided for use from a helicopter allowing for large areas to be patrolled and protected from enemy combat swimmers. The grenade launcher was developed in 1989 and introduced in 1990. Very little information is available on this weapon, but it has been mentioned as an option on several patrol boats in the Russian Navy.[citation needed]

Though large and somewhat unwieldy, the DP-64 serves an important role with few modern contemporaries in the small arms world.
