The invention relates to a firearm, to be more precise to devices providing the possibility of underwater firing from a dry firearm. The device for underwater firing from a firearm comprises a firearm with ammunition, a firing control means, and a controllable muzzle valve, a through-opening in said muzzle valve being intended for the flight of an underwater charge on discharge. Furthermore, the device comprises an outer housing, within which at least a firearm and ammunition are arranged. The firing control means is equipped with at least one pyrotechnic charge intended for producing, prior to firing, an excess gas pressure in the housing which exceeds the external water pressure. Furthermore, the firing control means is connected to the muzzle valve so as to provide the possibility of firing after the muzzle valve has opened as a result of an increase in the pressure of the pyrotechnic gas inside the housing and a cessation of the firing once the muzzle valve is closed. Furthermore, the muzzle valve is mounted so as to provide the possibility of the pyrotechnic gas passing through the through-opening therein out of the housing into the water. The invention increases the firing efficiency underwater and the reliability of the device for underwater firing from a firearm |
