The '''DP-64 Nepryadva'''<ref>{{Cite web|url=http://www.strategic-bureau.com/en/lance-grenade-dp-64-nepryadva/|title=DP-64 " Nepryadva " Grenade Launcher &#124; Strategic Bureau of Information|website=www.strategic-bureau.com}}</ref><ref>{{Cite web|url=https://www.pmulcahy.com/grenade_launchers/russian_grenade_launchers.htm|title=Russian Grenade Launchers|website=www.pmulcahy.com}}</ref> is a Russian special-purpose double-barreled over/under grenade launcher designed to protect surfaced submarines, ships, dockyards, water development works, and other coastal installations from combat swimmers and naval special forces. The weapon is [[Breech-loading weapon|breech-loading]] and operates much like a large [[shotgun]] with a side-break breech, utilizing both direct and indirect [[iron sights]]. The weapon is capable of firing grenades indirectly at ranges up to {{convert|400|m}}; 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 to diminish felt 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.

The DP-64 grenade launcher is now in serial production, said Pavel Sidorov, a representative of [[OKB|NPO]] [[Bazalt]], the designer of the DP-64, at the 2015 International Defense Exhibition (IDEX) in Abu Dhabi. Sidorov said that the company received a large order from Russia's Defense Ministry for the weapons. Previously, the DP-64 has only been built in small numbers for the Russian coast guard, Federal Security Service, and a handful of marine units.

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